Aims. The aim of this study was to report our experience at 3.5 years with outpatient total hip arthroplasty (THA). Methods. In this prospective cohort study, we included all patients who were planned to receive primary THA through the anterior approach between 1 April 2014 and 1 October 2017. Patient-related data and surgical information were recorded. Patient reported outcome measures (PROMs) related to the hip and an anchor question were taken preoperatively, at six weeks, three months, and one year after surgery. All complications, readmissions, and reoperations were registered. Results. Of the 647 THA patients who had surgery in this period through the anterior approach, 257 patients (39.7%) met the inclusion criteria and were scheduled for THA in an outpatient setting. Of these, 40 patients (15.6%) were admitted to the hospital, mainly because of postoperative nausea and/or dizziness. All other 217 patients were able to go home on the day of surgery. All hip-related PROMs improved significantly up to 12 months after surgery, compared with the scores before surgery. There were three readmissions and two reoperations in the outpatient cohort. There were no complications related to the outpatient THA protocol. Conclusion. These study results confirm that outpatient THA can be performed safe and successfully in a selected group of patients, with satisfying results up to one year postoperatively, and without outpatient-related complications, readmissions, and reoperations.

Aims. To examine incidence of complications associated with outpatient total hip arthroplasty (THA), and to see if medical comorbidities are associated with complications or extended length of stay. Patients and Methods. From June 2013 to December 2016, 1279 patients underwent 1472 outpatient THAs at our free-standing ambulatory surgery centre. Records were reviewed to determine frequency of pre-operative medical comorbidities and post-operative need for overnight stay and complications which arose. Results. In 87 procedures, the patient stayed overnight for 23-hour observation, with 39 for convenience reasons and 48 (3.3%) for medical observation, most frequently urinary retention (13), obstructive sleep apnoea (nine), emesis (four), hypoxia (four), and pain management (six). Five patients (0.3%) experienced major complications within 48 hours, including three transferred to an acute facility; there was one death. Overall complication rate requiring unplanned care was 2.2% (32/1472). One or more major comorbidities were present in 647 patients (44%), including previous coronary artery disease (CAD; 50), valvular disease (nine), arrhythmia (219), thromboembolism history (28), obstructive sleep apnoea (171), chronic obstructive pulmonary disease (COPD; 124), asthma (118), frequent urination or benign prostatic hypertrophy (BPH; 217), or mild chronic renal insufficiency (11). Conclusion. The presence of these comorbidities was not associated with medical or surgical complications. However, presence of one or more major comorbidity was associated with an increased risk of overnight observation. Specific comorbidities associated with increased risk were CAD, COPD, and frequent urination/BPH. Outpatient THA is safe for a large proportion of patients without the need for a standardised risk assessment score. Risk of complications is not associated with presence of medical comorbidities.

The purpose of our study is to examine the outcome of patients undergoing outpatient total hip arthroplasty with a BMI >35. Case-control matching on age, gender (46% female;54%male), and ASA (mean 2.8) with 51 outpatients BMI≥35 kg/m. 2. (mean of 40 (35–55)), mean age of 61 (38–78) matched to 51 outpatients BMI<35 kg/m. 2. (mean of 27 (17–34)) mean age 61 (33–78). Subsequently 47 inpatients BMI≥35 kg/m. 2. (mean of 40 (35–55)) mean age 62 (34–77) were matched outpatients BMI≥35 kg/m. 2. For each cohort, adverse events, readmission in 90 days, reoperations were recorded. Rate of adverse events was significantly higher in BMI ≥35: 15.69% verus 1.96% (p=0.039) with 5 reoperations in the BMI≥35 cohort vs 0 in the BMI<35 kg/m. 2. (p= 0.063). Readmissions did not differ between groups (p=0.125). No significant difference for all studied outcomes between the outpatient and inpatients cohorts with BMI≥35 kg/m. 2. The most complications requiring surgery/medical intervention (3B) were in the inpatient cohort of patients >35. The prevalence of Diabetes and Obstructive Sleep apnea was 21.6% and 29.4% for BMI>35 compared to 9.8% and 11.8%, for BMI <35, respectively. Severely obese patients have an overall higher rate of adverse events and reoperations however it should not be used a sole variable for deciding if the patient should be admitted or not

Microdiscectomy is the most commonly performed spine surgery in the world. Due to its technical simplicity and low complication rate, this was the first spine surgical procedure transitioning for one-day surgery. However, the economic assessment of this outpatient transition was never performed and the question on the real impact in the burden of spine care remains. This economic study aims to access the cost-utility of outpatient lumbar microdiscectomy when compared with the inpatient procedure. To do so, a cost-utility study was performed, adopting the hospital perspective. Direct medical costs were retrieved from the assessment of 20 patients undergoing outpatient lumbar microdiscectomy and 20 undergoing inpatient lumbar microdiscectomy, from a in a Portuguese NHS hospital. Utilities were calculated with quality-adjusted life-years were derived from Oswestry Disability Index values (ODI). ODI was assessed prospectively in outpatients in pre and 3- and 6-month post-operative evaluations. Inpatient ODI data were estimated from a meta-analysis. both probabilistic and deterministic sensitivity analyses were performed and incremental cost-effectiveness ratio (ICER) calculated. A willingness to pay (WTP) threshold of €60000/QALY gained with inpatient procedure was defined. Out results showed that inpatient procedure was cost-saving in all models tested. At 3-month assessment ICER ranged from €135753 to €345755/QALY, higher than the predefined WTP. At 6-month costs were lower and utilities were higher in outpatient, overpowering the inpatient procedure. Probabilistic sensitivity analysis showed that in 65% to 73% of simulations outpatient was the better option. The savings with outpatient were about 55% of inpatient values, with similar utility scores. No 30-day readmissions were recorded in either group. The mean admission time in inpatient group was 2.5 days. Since there is an overall agreement among spine surgeons that an uncomplicated inpatient MD would only need a one-day admission, an analysis reducing inpatient admission time for one day was also performed and outpatient remained cost-effective. In conclusion, as the first economic study on cost-utility of outpatient lumbar microdiscectomy, this study showed a significant reduction in costs, with a similar clinical outcome, proving this outpatient transition as cost-effective

The increased demand for total hip arthroplasty (THA) is having a significant impact on healthcare resources, resulting in increased interest in outpatient care pathways to reduce resource consumption. This study compared costs between patients who underwent outpatient THA using a Direct Anterior (DA) approach compared to a Direct Lateral (DL) approach to understand the effect of surgical approach on resource use. We conducted a prospective randomized controlled trial for DA patients undergoing primary THA. We compared patients in the outpatient arm of the trial to a prospective cohort of outpatient DL approach THAs. We recorded all costs including: equipment, length of stay in hospital, and laboratory or other medical tests. Following discharge, participants also completed a self-reported cost diary recording resource utilization such as emergency department visits or subsequent hospitalizations, tests and procedures, consultations or follow-up, healthcare professional services, rehabilitation, use of pain medications, informal care, productivity losses and out of pocket expenditures. We report costs from both Canadian public health care payer (HCP) and a societal perspective. The HCP perspective includes any direct health costs covered by the publicly funded system. In addition to the health care system costs, the societal perspective also includes additional costs to the patient (e.g. physiotherapy, medication, or assistive devices), as well as any indirect costs such as time off paid employment for patients or caregivers. We included 127 patients in the DA group (66.6 years old) and 51 patients in the DL group (59.4 years old) (p<0.01). There were no statistically significant differences in costs between groups from both the healthcare payer (DA= 7910.19, DL= 7847.17, p=0.80) and societal perspectives (DA= 14657.21, DL= 14581.21, p=0.96). In patients undergoing a successful outpatient hip replacement, surgical approach does not have an effect on cost from in hospital or societal perspectives

The coronavirus pandemic has reduced the capability of Canadian hospitals to offer elective orthopaedic surgery requiring admission, despite ongoing and increasing demands for elective total hip and total knee arthroplasty surgery (THA and TKA). We sought to determine if the coronavirus pandemic resulted in more outpatient THA and TKA in Nova Scotia, and if so, what effect increased outpatient surgery had on 90 day post-operative readmission or Emergency Department/Family Doctor (FD) visits. The study cohort was constructed from hospital Discharge Abstract Data (DAD), inpatient admissions, and National Ambulatory Care Reporting System (NACRS) data, day surgery observations, using Canadian Classification of Health Intervention codes to select all primary hip and knee procedures from 2005-2020 in Nova Scotia. Emergency Department and General Practitioner visits were identified from the Physician Billings data and re-admissions from the DAD and NACRS. Rates were calculated by dividing the number of cases with any visit within 90 days after discharge. Chi-squared statistics at 95% confidence level used to test for statistical significance. Knee and hip procedures were modelled separately. There was a reduction in THA and TKA surgery in Nova Scotia during the coronavirus pandemic in 2020. Outpatient arthroplasty surgery in Nova Scotia in the years prior to 2020 were relatively stable. However, in 2020 there was a significant increase in the proportion and absolute number of outpatient THA and TKA. The proportion of THA increased from 1% in 2019 to 14% in 2020, while the proportion of TKA increased from 1% in 2019 to 11% in 2020. The absolute number of outpatient THA increased from 16 cases in 2019, to 163 cases in 2020. Outpatient TKA cases increased from 21 in 2019, to 173 in 2020. The increase in outpatient surgery resulted in an increase in 90 day presentations to ED following TKA but not THA which was not statistically significant. For outpatient THA and TKA, there was a decrease in 90 day readmissions, and a statistically significant decrease in FD presentations. Outpatient THA and TKA increased significantly in 2020, likely due to the restrictions imposed during the coronavirus pandemic on elective Orthopaedic surgery requiring admission to hospital. The increase in outpatient surgery resulted in an increase in 90 day presentations to ED for TKA, and a decrease in 90 day readmissions and FD presentations for THA and TKA. Reducing the inpatient surgical burden may result in a post-operative burden on ED, but does not appear to have caused an increase in hospital readmission rates

Introduction. The Centers for Medicare and Medicaid Services (CMS) removed total knee arthroplasty (TKA) from inpatient-only status in 2018. Our goal was to measure the adoption of outpatient TKAs, the impact on re-treatment rates, and the economic implications for hospitals. Methods. We utilized 100% national Medicare Part A fee-for-service (FFS) patient-level claims data for 2017–2018. We excluded DRG 469 TKAs since they are unlikely to be outpatient candidates, which left 257,107 primary TKAs in 2017 and 264,393 in 2018. We examined the time trend in monthly case volume and 30-day retreatment rate (defined as percent of patients having a second TKA within 30 days of the first. We calculated the loss in revenue for a hospital by multiplying the decrease in payment rate between inpatient and outpatient by the outpatient and total 2018 TKA volume. Results. In 2017 0.2% of primary TKAs were performed outpatient. Following the rule change, 25% of cases were performed outpatient in Q1 2018. This stayed at 25% in Q2, increased to 27% in Q3, and then increased to 30% in Q4 2018. The 30-day re-treatment rate was 0.16% in 2017 and 0.15% in 2018. Across hospitals there was the following distribution in the decrease in payment rate from inpatient to outpatient TKAs in 2018: 10. th. percentile: $1,994, 25. th. : $2,612, 50. th. : $3,487, 75. th. : $4,918, 90. th. : $7,231. In 2018 outpatient TKA coding cost hospitals (saved CMS) $243M in Medicare FFS payments (an average of $89,000 per hospital). If all TKAs were performed outpatient hospital Medicare FFS payments would have been $965M lower ($353,000 per hospital) in 2018. Conclusion. Outpatient TKA volumes grew through 2018. This did not impact 30-day retreatment rates. Medicare FFS payment rates declined by a median of $3,487 per outpatient case. As more TKAs are performed outpatient, total Medicare payments will further decline. For figures, tables, or references, please contact authors directly

Percutaneous flexor tenotomy involves cutting the flexor digitorum tendons to correct claw toe deformity to treat apical pressure areas and prevent subsequent infection in patients with peripheral neuropathy. Performing this under ultrasound guidance provides reassurance of complete release of the tendon and increases procedural safety. This study is a retrospective case series evaluating the effectiveness, safety, and patient satisfaction of performing percutaneous ultrasound-guided flexor tenotomy in an outpatient setting. People with loss of protective sensation, a digital flexion deformity, and an apical toe ulcer or pre-ulcerative lesion who presented to our institution between December 2019 and June 2022 were included in this study. Participants were followed-up at a minimum of 3 months. Time to ulcer healing, re-ulceration rate, patient satisfaction, and complications were recorded. An Australian cost analysis was performed comparing this procedure performed in rooms versus theatres. There were 28 ulcers and 41 pre-ulcerative lesions. A total of 69 tenotomy procedures were performed on 38 patients across 52 episodes of care. The mean time to ulcer healing was 22.5 +/- 6.4 days. There were 2 cases of re-ulceration. 1 patient sustained a transfer lesion. There were four toes that went onto require amputation, all in the setting of pre-existing osteomyelitis. 94% of patients strongly agreed that they were satisfied with the outcome of the procedure. Costs saved were estimated to be $1426. Flexor tenotomy is a minimally invasive procedure that can be performed in the outpatient setting, and therefore without delay to treatment, reducing risk of ulcer progression and need for subsequent amputation. This is the first study to report on flexor tenotomy under ultrasound-guidance. Ultrasound-guided percutaneous flexor tenotomy is safe and effective, with high patient satisfaction and low recurrence rates. This performance in the outpatient setting ensures significant time and cost savings for both the practitioner and patient

Introduction. Total hip arthroplasty (THA) is an effective surgery for the treatment of advanced osteoarthritis but increasing numbers of these procedures are having a significant impact on healthcare budgets. One route to mitigate the increasing costs is outpatient THA, discharging patients on the same day as their surgery. The purpose of this study was to determine the cost of outpatient THA compared to standard overnight stay in hospital. Methods. This was a prospective-randomized controlled trial for patients undergoing primary THA through a direct anterior approach. Participants were randomized to be discharged on the same day as surgery, as outpatients, or on day one post-surgery, as inpatients, using a Zelen consent model. Adverse events were assessed, and participants completed self-reported cost questionnaires at two-, six- and 12-weeks post-surgery, and the WOMAC preoperatively and at 12-weeks post-surgery. We performed a cost analysis from health care payer (HCP) and societal perspectives. Results. 106 patients were enrolled in this study, with 50 randomized to outpatient and 56 randomized to inpatient THA. Seven patients from the outpatient group and five patients from the inpatient group crossed-over. Adverse event rate was similar between the groups with seven events in four participants in the inpatient group and three events in two participants in the outpatient group. WOMAC scores were not significantly different between the groups (p=0.12). From both a HCP and societal perspective, inpatient THA was more costly than outpatient THA. The cost difference was $3,353.15 for HCP (p<0.0001) and $3,703.30 for societal (p=0.003) in favour of outpatient THA. Conclusion. Our results suggest that outpatient THA is a cost-saving procedure when compared to inpatient THA from both HCP and societal perspectives. We will continue recruitment to investigate whether these results hold true in a larger sample as well as assess for cost-effectiveness, patient safety and satisfaction. Acknowledgements.

Aims. To identify variables independently associated with same-day discharge (SDD) of patients following revision total knee arthroplasty (rTKA) and to develop machine learning algorithms to predict suitable candidates for outpatient rTKA. Methods. Data were obtained from the American College of Surgeons National Quality Improvement Programme (ACS-NSQIP) database from the years 2018 to 2020. Patients with elective, unilateral rTKA procedures and a total hospital length of stay between zero and four days were included. Demographic, preoperative, and intraoperative variables were analyzed. A multivariable logistic regression (MLR) model and various machine learning techniques were compared using area under the curve (AUC), calibration, and decision curve analysis. Important and significant variables were identified from the models. Results. Of the 5,600 patients included in this study, 342 (6.1%) underwent SDD. The random forest (RF) model performed the best overall, with an internally validated AUC of 0.810. The ten crucial factors favoring SDD in the RF model include operating time, anaesthesia type, age, BMI, American Society of Anesthesiologists grade, race, history of diabetes, rTKA type, sex, and smoking status. Eight of these variables were also found to be significant in the MLR model. Conclusion. The RF model displayed excellent accuracy and identified clinically important variables for determining candidates for SDD following rTKA. Machine learning techniques such as RF will allow clinicians to accurately risk-stratify their patients preoperatively, in order to optimize resources and improve patient outcomes.

Aims. The aim of the present study was to compare the 30- and 90-day re-admission rates and complication rates of outpatient and inpatient total shoulder arthroplasty (TSA). Patients and Methods. The United States Medicare Standard Analytical Files database was questioned to identify patients who had undergone outpatient or inpatient TSA between 2005 and 2012. Patient characteristics were compared between the two groups using chi-squared analysis. Multivariate logistic regression analysis was used to control for differences in baseline patient characteristics and to compare the two groups in terms of post-operative complications within 90 days and re-admission within 30 days and 90 days. Results. A total of 123 347 Medicare subscribers underwent TSA between 2005 and 2012; 3493 (2.8%) had the procedure performed as an outpatient. A significantly greater proportion of patients who underwent TSA as inpatients were women, had a history of smoking, and had a greater incidence of medical comorbidity including diabetes, coronary artery disease, congestive heart failure, and chronic kidney disease (p < 0.05 for all). Re-admission rates were significantly higher for inpatients at both 30 days (0.83% versus 0.60%, p = 0.016, odds ratio 1.8) and 90 days (2.87% versus 2.04%, p < 0.001, odds ratio 1.8). Complications, including thromboembolic events (p < 0.001) and surgical site infection (p = 0.002), were significantly higher in inpatients. Conclusion. Patients who underwent TSA on an outpatient basis were overall younger and healthier than those who had inpatient surgery, which suggests that patient selection was taking place. After controlling for age, gender, and medical conditions, patients who underwent TSA as outpatients had lower rates of 30- and 90-day re-admission and a lower rate of complications than inpatients. .

The response to the COVID-19 pandemic has raised the profile and level of interest in the use, acceptability, safety, and effectiveness of virtual outpatient consultations and telemedicine. These models of care are not new but a number of challenges have so far hindered widespread take-up and endorsement of these ways of working. With the response to the COVID-19 pandemic, remote and virtual working and consultation have become the default. This paper explores our experience of and learning from virtual and remote consultation and questions how this experience can be retained and developed for the future.

Introduction. External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting. Materials & Methods. This prospective case series evaluated the first 20 consecutive cases of EF removal in the outpatient clinic between 10/06/22 to 16/09/22. Regional anaesthesia using ultrasound-guided blockade of peripheral nerves was administered using 1% lidocaine due to its rapid onset and short half-life. Patients were assessed for additional analgesia requirement, asked to evaluate their experience and perceived pain using the Visual Analogue Scale (VAS). Results. Twenty patients were included in the study. The mean age was 46.6 years (range 21–85 years). Two thirds were male patients (N=13). Post procedure all patients indicated positive satisfaction ratings, each participant responding as either ‘satisfied’ (N=4), ‘very satisfied’ (N=15) or ‘highly satisfied’ (N=1). In addition, 85% of participants reported they would opt for this method of EF removal in future should it be necessary. VAS for pain immediately following completion of the procedure was low, with an average score of 0.45 (range 0–4), where a score of 0= ‘No pain’, and 10 = ‘worst pain possible’. Conclusions. We present the first description of outpatient EF removal using sole regional anaesthesia, with a prospective case series of 20 EF removed in fully awake patients. This novel technique is cost-effective, reproducible, and safe. This not only reduces the burden of these surgical cases on an operating list but also improves patient experience when compared to other forms of conscious sedation. By eliminating the use of Entonox and methoxyflurane for sedation and analgesia, this project demonstrates a method of improving environmental sustainability of surgery, anaesthesia and operating theatres

Aims. The proportion of arthroplasties performed in the ambulatory setting has increased considerably. However, there are concerns whether same-day discharge may increase the risk of complications. The aim of this study was to compare 90-day outcomes between inpatient arthroplasties and outpatient arthroplasties performed at an ambulatory surgery centre (ASC), and determine whether there is a learning curve associated with performing athroplasties in an ASC. Methods. Among a single-surgeon cohort of 970 patients who underwent arthroplasty at an ASC, 854 (88.0%) were matched one-to-one with inpatients based on age, sex, American Society of Anesthesiologists (ASA) grade, BMI, and procedure (105 could not be adequately matched and 11 lacked 90-day follow-up). The cohort included 281 total hip arthroplasties (THAs) (32.9%), 267 unicompartmental knee arthroplasties (31.3%), 242 primary total knee arthroplasties (TKAs) (28.3%), 60 hip resurfacings (7.0%), two revision THAs (0.3%), and two revision TKAs (0.3%). Outcomes included readmissions, reoperations, visits to the emergency department, unplanned clinic visits, and complications. Results. The inpatient and outpatient groups were similar in all demographic variables, reflecting successful matching. The reoperation rate was 0.9% in both cohorts (p = 1.000). Rates of readmission (2.0% inpatient vs 1.6% outpatient), any complications (5.9% vs 5.6%), minor complications (4.2% vs 3.9%), visits to the emergency department (2.7% vs 1.4%), and unplanned clinic visits (5.7% vs 5.5%) were lower in the outpatient group but did not reach significance with the sample size studied. A learning curve may exist, as seen by significant reductions in the reoperation and overall complication rates among outpatient arthroplasties over time (p = 0.032 and p = 0.007, respectively), despite those in this group becoming significantly older and heavier (both p < 0.001) during the study period. Conclusion. Arthroplasties performed at ASCs appear to be safe in appropriately selected patients, but may be associated with a learning curve as shown by the significant decrease in complication and reoperation rates during the study period.

The brief answer is no….I do not believe that outpatient total joint arthroplasty is the emergent standard of care. However, for some patients and some surgeons I do believe that outpatient total joint arthroplasty can be performed safely and with greater comfort and convenience for the patient. Further, for the surgeon, it can provide greater control over the care environment if performed at an ambulatory surgery center. Patient selection is paramount in my opinion for safely performing outpatient total joint arthroplasty. While some have attempted to define specific criteria, our own criteria include patients with simple orthopaedic problems who are healthy, trustworthy and have a good support system of family or friends to assist them. As surgeons we must also be self-aware as the margin for error, particularly at a freestanding ambulatory surgery center, is narrow. Operative times should be reliably brief and blood loss should be minimal to allow for a safe discharge on the same day. Further the incidence of intraoperative complications such as fractures at the time of total hip arthroplasty or ligament injuries during total knee arthroplasty should be low. The surgeon should also be prepared with the equipment to address these common issues, if they do occur. In our review of the NSQIP data set we matched 1,236 outpatient TJA 1:1 with inpatients based on propensity scores. The risk of 30-day readmissions and complications was no different between groups, although inpatients had a higher rate of VTE and outpatients had a higher risk of re-operation. Risk factors for adverse events included patient age > 85 years old, diabetes and BMI > 35. Likewise in a review of results from my own practice, we have seen no difference in the risk of complications. As health care providers we must keep the safety of our patients paramount at all times. Further, we must be fiscally responsible to avoid costly complications, reoperations and readmissions. With conservative patient selection and careful surgical technique I believe that outpatient TJA offers an attractive alternative that is safe, cost effective and associated with high satisfaction for both patients and surgeons

Aims. Currently, there is no single, comprehensive national guideline for analgesic strategies for total joint replacement. We compared inpatient and outpatient opioid requirements following total hip arthroplasty (THA) versus total knee arthroplasty (TKA) in order to determine risk factors for increased inpatient and outpatient opioid requirements following total hip or knee arthroplasty. Methods. Outcomes after 92 primary total knee (n = 49) and hip (n = 43) arthroplasties were analyzed. Patients with repeat surgery within 90 days were excluded. Opioid use was recorded while inpatient and 90 days postoperatively. Outcomes included total opioid use, refills, use beyond 90 days, and unplanned clinical encounters for uncontrolled pain. Multivariate modelling determined the effect of surgery, regional nerve block (RNB) or neuraxial anesthesia (NA), and non-opioid medications after adjusting for demographics, ength of stay, and baseline opioid use. Results. TKAs had higher daily inpatient opioid use than THAs (in 5 mg oxycodone pill equivalents: median 12.0 vs 7.0; p < 0.001), and greater 90 day use (median 224.0 vs 100.5; p < 0.001). Opioid refills were more likely in TKA (84% vs 33%; p < 0.001). Patient who underwent TKA had higher independent risk of opioid use beyond 90 days than THA (adjusted OR 7.64; 95% SE 1.23 to 47.5; p = 0.01). Inpatient opioid use 24 hours before discharge was the strongest independent predictor of 90-day opioid use (p < 0.001). Surgical procedure, demographics, and baseline opioid use have greater influence on in/outpatient opioid demand than RNB, NA, or non-opioid analgesics. Conclusion. Opioid use following TKA and THA is most strongly predicted by surgical and patient factors. TKA was associated with higher postoperative opioid requirements than THA. RNB and NA did not diminish total inpatient or 90-day postoperative opioid consumption. The use of acetaminophen, gabapentin, or NSAIDs did not significantly alter inpatient opioid requirements.

The discussion of outpatient unicompartmental knee arthroplasty (UKA) requires proof that it can be done safely and effectively, and also begs the question of whether it can be performed in an ambulatory surgery center (ASC) rather than a general hospital (which raises costs and is typically less efficient). Successful outpatient UKA requires carefully crafted algorithms/protocols, home support, preoperative planning and preparation, expectation management, risk stratification (not everyone is a candidate), perioperative pain management and buy-in from patients, support networks and the health care team. Relatively little data is available on the feasibility, safety and potential cost savings associated with this shift in care. We evaluated the costs and short term outcomes and complications of 150 consecutive UKAs performed in an ASC compared to those done in a general hospital both on an inpatient and outpatient basis. Determination of the setting of the outpatient surgery was made based on geographic preference by the patients; otherwise choice of inpatient or outpatient surgery in the hospital was left to the discretion of the surgeon and was primarily based on the patients' comorbidity profile and circumstances of home help. Total direct facility costs were calculated, including institutional supplies and services, anesthesia services, implants, additional PACU medications and services required, and costs associated with operating room use. Only total cost was evaluated, as it is the most consistent cost variable amongst the two institutions evaluated. The mean total direct cost of UKA in a general community hospital with an overnight stay was 1.24 and 1.65 times greater than the cost of UKA performed at the same hospital or an ASC on an outpatient basis, respectively. The mean total direct cost of outpatient UKA in a general hospital was 1.33 times greater than the mean total cost of UKA performed in an ASC. Semi-autonomous robotic technology has been introduced to optimise accuracy of implant positioning and soft tissue balance in UKA, with the expectation of resultant improvement in durability and implant survivorship. Currently, nearly 20% of UKA's in the U.S. are being performed with robotic assistance. It is anticipated that there will be substantial growth in market penetration over the next decade, projecting that nearly 37% of UKA's and 23% of TKA's will be performed with robotics in 10 years (Medical Device and Diagnostic Industry, March 5, 2015). First generation robotic technology improved substantially implant position compared to conventional methods; however, high capital costs, uncertainty regarding the value of advanced technologies, and the need for preoperative CT scans were barriers to broader adoption. Newer image-free robotic technology offers an alternative method for further optimizing implant positioning and soft tissue balance without the need for preoperative CT scans and with price points that make it suitable for use in an ASC. Currently, as a result of cost and other practical issues, <1% of first generation robotic technologies are being used in ASC's. Alternatively, more than 35% of second generation robotic systems are in use in ASC's for UKA, due to favorable pricing. In conclusion, UKA can be safely performed in the outpatient setting in select patients. Additionally, we demonstrated a substantial cost savings when UKA is performed in an outpatient setting and care is shifted from a general community hospital to an ASC. Finally, robotics can be utilised to optimise accuracy of implant placement and soft tissue balance in UKA, and newer image-free robotic technology is cost effective for outpatient UKA

Aims. Recent improvements in surgical technique and perioperative blood management after total joint replacement (TJR) have decreased rates of transfusion. However, as many surgeons transition to outpatient TJR, obtaining routine postoperative blood tests becomes more challenging. Therefore, we sought to determine if a preoperative outpatient assessment tool that stratifies patients based on numerous medical comorbidities could predict who required postoperative haemoglobin (Hb) measurement. Methods. We performed a prospective study of consecutive unilateral primary total knee arthroplasties (TKAs) and total hip arthroplasties (THAs) performed at a single institution. Prospectively collected data included preoperative and postoperative Hb levels, need for blood transfusion, length of hospital stay, and Outpatient Arthroplasty Risk Assessment (OARA) score. Results. A total of 504 patients met inclusion criteria. Mean age at time of arthroplasty was 65.3 years (SD 10.2). Of the patients, 216 (42.9%) were THAs and 288 (57.1%) were TKAs. Six patients required a blood transfusion postoperatively (1.19%). Transfusion after surgery was associated with lower postoperative day 1 Hb (median of 8.5 (interquartile range (IQR) 7.9 to 8.6) vs 11.3 (IQR 10.4 to 12.2); p < 0.001), longer length of stay (1 day (IQR 1 to 1) vs 2 days (IQR 2 to 3); p < 0.001), higher OARA score (median of 60.0 (IQR 40 to 75) vs 5.0 (IQR 0-35); p = 0.001), and total hip arthroplasty (p < 0.001). All patients who received a transfusion had an OARA score > 34; however, this did not reach statistical significance as a screening threshold. Conclusion. Risk of blood transfusion after primary TJR was uncommon in our series, with an incidence of 1.19%. Transfusion was associated with OARA scores > 60. The OARA score, not American Society of Anesthesiologists grade, reliably identified patients at risk for postoperative blood transfusion. Selective Hb monitoring may result in substantial cost savings in the era of cost containment. Cite this article: Bone Joint J 2021;103-B(1):65–70

Closed ankle fractures have been reported to account for 10% off all fractures presenting to the Emergency Department. Many of these injuries require acute surgical management either via direct admission or through defined outpatient surgical pathways. While both methods have been shown to be safe, few studies have examined the cost effectiveness of each clinical scenario. The purpose of this study is to compare cost and resource utilization associated with inpatient and outpatient ankle fracture surgery at a Canadian academic institution. This is a retrospective chart review of patients who underwent acute ankle fracture surgery at London Health Sciences Centre between 2016 and 2018. Thirty patients who underwent inpatient ankle surgery for closed, isolated ankle fractures at University Hospital were compared to 30 consecutive patients who underwent outpatient ankle surgery for similar fractures at Victoria hospital. Data pertaining to age at time of surgery, sex, BMI, fracture type, operating/recovery room time, and length of hospital stay were collected. All emergency room visits, readmissions and complications within 30 days of surgery were also recorded. Inpatient and outpatient cohorts were similar with respect to average age (48 vs. 44, P=0.326) and body mass index (29.8 vs. 29.1, P=0.741). There was a greater proportion of patients with an American Society of Anesthesia (ASA) Classification of 3 or greater in the inpatient surgery group (48% vs. 23%). The inpatient group spent an average of 1.2 days in hospital while waiting for surgery and a average of 72 hours in hospital for their entire surgical encounter. The outpatient group spent an average of eight days (at home) waiting for surgery while spending an average of 7.4 hours in hospital during their entire surgical encounter. Outpatient ankle fracture surgery was associated with a cost savings of 35.9% in comparison to inpatient ankle fracture surgery (P < 0 .001). There were no significant differences in the rates of emergency room visits, readmissions, or complications between cohorts. Preliminary findings suggest that outpatient ankle fracture surgery is appropriate for most patients, requires less hospital resources and is associated with similar rates of readmission and complications as inpatient surgery. An established outpatient surgical pathway may offer significant cost savings in the treatment of the common closed ankle fracture that requires surgical intervention

Outpatient total hip arthroplasty (THA) has remained controversial and challenging. Traditional hospital stays following total joint arthroplasty were substantial and resulted in increased rates of morbidity, significant pain, and severe restriction in mobility. Advancements in the surgical approach, anesthetic regimens, and the initiation of rapid rehabilitation protocols have had an impact on the length of recovery following elective THA. Still, very few studies have specifically outlined outpatient hip arthroplasty and, thus far, none have addressed the use of robotic-arm navigation in outpatient THA. This article describes in detail the technique used to perform outpatient THA with the use of robotic-arm assistance. We believe that outpatient THA using robotic-arm assistance in combination with tissue-preserving surgery, multi-modal pain and nausea management, early rehabilitation, and stringent patient selection yields a suitable alternative to inpatient joint replacement

An outpatient TKA program was developed by integrating advances in analgesia, rehabilitation, and minimally invasive surgical techniques with the objective of improving value in elective total knee arthroplasty (TKA) while maintaining quality standards. Previous studies have established the safety of outpatient TKA in selected populations, but the literature is devoid of outcome measures in these patients. Our goal was to investigate the quality of recovery, patient satisfaction, and safety profile in the first 90 days undergoing outpatient TKA. One hundred TKAs in 93 consecutive patients with end-stage arthritis of the knee candidate for primary TKA were enrolled in this prospective matched cohort study. Patients that underwent inpatient TKA (47 TKAs) were compared with patients that underwent planned outpatient TKA (53 TKAs). The following 28 day post-operative scores were recorded: quality of recovery (QoR-18) and pain scores by Numerical Rating Scale (NRS-11). Satisfaction with pain control (0 to 10) and quantity of opioid use was collected. Secondary outcome measures of 90-day complications, readmissions, and emergency department (ED) visits were recorded. Ninety-six percent of patients planned for outpatient TKA met our defined multidisciplinary criteria for same-day discharge. QoR-18 at post-operative day one was statistically higher in the outpatient TKA group. Otherwise, outcome measures were not statistically different between the 2 groups. Two patients required overnight admission: 1 for extended motor-block and 1 for vasovagal syncope. There were 7 ED visits in the in the outpatient group and 4 in the inpatient group. One outpatient was admitted for irrigation and debridement with liner exchange for an acute infection 2 weeks post-operatively. One inpatient required manipulation under anesthesia at six weeks post-operatively. Outpatient TKA in selected patients produced a post-operative quality of recovery and patient satisfaction similar to that of inpatient TKA. Our results support that outpatient TKA is a safe alternative that should be considered due to its potential cost-savings and comparable recovery

Length of hospital stay has been decreased to the point where the next logical progression in arthroplasty surgery is outpatient arthroplasty procedures. This trend has already happened for procedures formerly regarded as “inpatient” procedures such as upper extremity surgery, arthroscopy, anterior cruciate ligament reconstruction, foot and ankle procedures, and rotator cuff repair. Refinement of surgical techniques, anesthesia protocols, and patient selection has facilitated this transformation. Today, hip, knee and shoulder arthroplasty can be performed safely as outpatient procedures by implementing surgical and protocol refinements. Understanding and addressing, safely, the reasons that surgeons and patients believe they “need” a hospital admission is the cornerstone to outpatient arthroplasty. This program can be highly beneficial to patients, surgeons, anesthesia, ambulatory surgery centers, and payors as arthroplasty procedures shift to the outpatient space. It will always cost more to perform these procedures in hospitals therefore opening up significant opportunities. The less efficiently run hospital in-patient setting demands over-treatment of each patient to fit him or her into the mold of inpatient surgery. Patient satisfaction is very high in the outpatient setting. Patients can recover in their own home with reduced inpatient services and by utilizing outpatient physical therapy. The surgeon efficiently controls the local environment, and thus the overall patient experience and satisfaction are improved in the outpatient setting. The surgeon's role changes from commoditised technician in the hospital setting to coordinator of the entire care experience including pre-operative care, imaging, anesthesia, peri-operative care mapping, post-operative care, and enhanced coordination with therapy providers. An outpatient arthroplasty program involves multiple individuals and specialised protocols for pre-operative, peri-operative, and post-operative care. These include patient selection and education, anesthesia and analgesia, and minimally invasive surgical techniques. By implementing these protocols and a minimally invasive Watson-Jones approach, one study has reported 77% utilization of outpatient THA, 99% success with day of surgery discharge, and a 1% readmission or complication rate. Outpatient arthroplasty is safe, it's better for us and our patients, and it is here now. In an outpatient environment the surgeon actually spends more time with the patients and family in a friendly environment. Patients feel safe and well cared for, and are highly satisfied with their arthroplasty experience. In a typical day a surgeon can perform 6–8 outpatient arthroplasty procedures with multiple interactions with each patient and their family throughout the day. Avoidance of narcotics with peripheral and local blocks will increase the eligibility for outpatient surgery and decrease the need for overnight hospitalization. The singular focus on the patient and the avoidance of over-treatment will become the standard of care for total hip and total knee arthroplasty in much the same way as for other procedures once deemed “inpatient” surgeries

Introduction. Outpatient total joint arthroplasty (TJA) is emerging as a viable alternative to the historically accepted hospital based inpatient TJA in the United States. Several studies have focused on the financial advantages of outpatient TJA, however little research has discussed patient reported outcome measures (PROM) and the overall patient experience. This is a retrospective comparison of PROM data in patients undergoing outpatient vs. inpatient total hip arthroplasty (THA). Methods. An internal quality metric database analysis was performed on patients undergoing THA between 2/14/14 to 5/1/2015. Outpatients underwent THA at a newly opened ambulatory surgery center. Inpatients underwent THA in a hospital setting. Ninety-six outpatients and 152 inpatients between the ages of 29–65 years old were included. The Oxford Hip, VAS Pain, and Treatment Satisfaction Questionnaires were completed pre-operatively, and at 3- and 6-months post-op. The Treatment Satisfaction Questionnaire asked 8 questions including “how well did the surgery on your joint increase your ability to perform regular activities?” Patients chose from poor, fair, good, very good, and excellent. Chi-squared analyses determined differences in percentages between outpatient and inpatient PROM. Independent samples t-tests determined significant improvements between pre-op and 3 month post-op PROM scores. Results. Outpatients reported significantly greater improvements in functionality at 3 months post-operatively compared to inpatients (20.9 vs. 17.0 raw score improvement) as assessed using the Oxford Hip Score Questionnaire. Thus, outpatients showed a 23% greater improvement compared to inpatients. This was statistically significant (p<0.01). Outpatients showed a significantly higher improvement in VAS pain score compared to inpatients (84.5% vs. 66.2%, p<0.01) at 3 months post-op. Outpatients reported a significantly higher score (on a 100 point scale) when rating how normal their joint felt (85.0 vs. 76.8, p=.022) at 3 months post-op. A significantly higher percentage of outpatients reported their pain relief as “excellent” compared to inpatients (71.7% vs. 56.3%, p<0.01) at 3 months post-op. A significantly higher percentage of outpatients reported their ability to perform regular activities as “excellent” compared to inpatients (57.7% vs. 30.6%, p=.002) at 3 months post-op. A significantly higher percentage of outpatients reported their ability to perform regular activities as “very good-to-excellent” compared to inpatients (82.7% vs. 65.9%, p=.033) at 3 months post-op. A significantly higher percentage of outpatients reported that they “definitely would” have surgery again compared to inpatients (84.6% vs. 69.4%, p=.046) at 3 months post-op. Conclusion. Significantly greater PROM and VAS pain score improvements were reported by outpatient THA patients vs. inpatient THA patients of similar age between the pre-operative time point and 3-months post-op. Outpatient THA patients report a greater improvement on the Oxford Hip Score scale, VAS pain score, THA normal joint, and THA satisfaction questionnaire. The implementation of outpatient THA procedures shows greater overall patient satisfaction and improvement 3 months post-operation. This study demonstrates our initial experience with outpatient THA. The results have met and/or exceeded the inpatient experience with regards to patient reported outcomes measures

Introduction. Outpatient total joint arthroplasty (TJA) is emerging as a viable alternative to the historically accepted hospital-based inpatient TJA in the United States. Several studies have focused on the financial advantages of outpatient TJA, however little research has discussed patient reported outcome measures (PROM) and the overall patient experience. The purpose of this study is to compare PROM data in patients undergoing outpatient vs. inpatient total knee arthroplasty (TKA) performed in the first year of a newly opened outpatient facility. Methods. An internal quality metric database analysis was performed on patients undergoing TKA between 2/14/14 and 5/1/2015. Outpatient TKA was performed at an ambulatory surgery center. Three-hundred and forty-three TKA patients (both inpatient and outpatient) between the ages of 37–65 years old were included. The Oxford Hip, VAS Pain, and Treatment Satisfaction Questionnaires were completed pre-operatively, and at 3- and 6-months post-op. The Treatment Satisfaction Questionnaire asks 8 questions including “how well did the surgery on your joint increase your ability to perform regular activities?” Patients chose from poor, fair, good, very good, and excellent. Chi-squared analyses determined differences in percentages between outpatient and inpatient PROM. Independent samples t-tests determined significant improvements between pre-op and 6 month post-op PROM scores. Results. Outpatients showed a significantly higher improvement in VAS pain score at 6 months compared to inpatients (74.5% vs. 61.6%, p<0.01). Outpatients rated their pain relief as “very good-to-excellent” significantly higher than inpatients (90.0% vs. 74.0%, p=.020) at 6 months post-op. Outpatients rated their ability to perform regular activities as “very good-to-excellent” more frequently as inpatients (82.0% vs. 59.3%, p=.004) at 6 months post-op. This difference was significant. A significantly higher percentage of outpatients reported “very good-to-excellent” meeting of expectations compared to inpatients (82.0% vs. 63.4%, p=.017) at 6 months post-op. No statistical difference was found between outpatients and inpatients in terms of Oxford Knee (function) scores at 6 months post-op. No statistical differences between the inpatient and outpatient groups were noted at the 3 month post-op time point. Conclusion. Significantly greater improvement was reported by outpatient TKA patients vs. inpatient TKA patients at six months post-op. Outpatients report a greater improvement on the VAS Pain score, and report a higher frequency of top-box ratings on the TKA normal joint and TKA satisfaction questionnaires. The implementation of outpatient TKA procedures shows greater overall patient satisfaction and improvement 6 months post-operation. This study illustrates that a de novo outpatient TJA pathway and facility can be successfully implemented with very high levels of patient satisfaction and patient reported success

To our knowledge, we are the only centre in the UK where Achilles tenotomies (TA) for CTEV Ponseti correction are performed in outpatient clinic under local anaesthetic by an Advanced Physiotherapy Practitioner (APP) in orthopaedics. This study aims to present the outcomes and safety of this practice. Retrospective analysis of cases of idiopathic CTEV undergoing Ponseti correction January 2020 to October 2022. Demographic data: Pirani score and number of casts before boots and bar. Patients were divided into five groups: Group 1: TA performed by an Orthopaedic consultant under general anaesthetic (GA) in theatre. Group 2: TA performed by an Orthopaedic consultant under local anaesthetic (LA) in theatre. Group 3: TA performed by APP under GA in theatre. Group 4: TA performed by APP under LA in theatre. Group 5: TA performed by an APP under LA in outpatient clinic. Complications recorded: revision TA, infection, neurovascular injury or need for re-casting. Mean follow up 18 months. 45 feet included. Mean Pirani score 5.5, age started casting 33 days and total number of casts 6. No significant difference in demographic details between groups. 6, 4, 20, 5 and 10 tenotomies were performed in groups 1, 2, 3, 4, and 5 respectively. Complications were 1 revision tenotomy from group 2, one from group 4 and 1 renewal of cast from 3. This study demonstrates that TAs performed in outpatient clinic under LA by an APP is safe and feasible. No increase in complications were observed compared to TAs performed by orthopaedic consultants

Total hip arthroplasty (THA) continues moving to the outpatient arena, and may be feasible for some conversion and revision scenarios. Controversy surrounds appropriate patient selection. The purpose of this study is to report complications associated with outpatient revision and conversion THA, and to determine if comorbidities are associated with complications or overnight stay. From June 2013 through March 2018, 43 patients (44 hips) underwent conversion (n=9) or revision (n=35) THA at a free-standing ambulatory surgery center. Mean patient age was 58.4 years, and 52% of patients were male. Conversion procedures were failed fracture fixation with retained hardware and all involved both femoral and acetabular replacement. Revision procedures involved head only in one, head and liner in 20, cup and head in 8, stem only in one, stem and liner in 4, and full revision in one. Forty-one (93%) were discharged same day without incident, none required transfer to acute facility, and 3 required overnight stay with 2 of these for convenience and only one for a medical reason, urinary retention. Three patients with early superficial infection, including 2 diagnosed by positive intraoperative cultures, were successfully treated with oral antibiotics. There were no major complications, readmissions, or subsequent surgeries within 90 days. One or more major comorbidities were present in 15 patients (34%) including 1 valvular disease, 7 arrhythmia, 2 thromboembolism history, 3 obstructive sleep apnea, 3 chronic obstructive pulmonary disease, 2 asthma, 4 frequent urination, and 1 renal disease. The single patient who stayed overnight for a medical reason had no major medical comorbidities. Outpatient arthroplasty, including revision THA in some scenarios, is safe for many patients. Presence of medical comorbidities was not associated with risk of complications. The paradigm change of patient education, medical optimization, and a multimodal program to mitigate risk of blood loss and reduce need for narcotics facilitates performing arthroplasty safely in an outpatient setting

Significant advances in perioperative pain management, such as multimodal periarticular injection, and subtler advances in surgical technique have resulted in improved postoperative experiences for patients with less pain, earlier rehabilitation, and shorter stays in hospital. Concurrently, and by applying the learnings from above, significant advances have been made in unicompartmental knee arthroplasty care pathways leading to safe programs for outpatient surgery. A natural extension of this process has been the exploration of outpatient total joint arthroplasty (TJA). There are some papers written on the topic, but not many. The papers are generally report that outpatient TJA can be a safe and effective procedure, but the devil is in the detail. Firstly, most authors in this field carry a bias towards positive outcomes given they fact they are expert, academic, and innovative surgeons, often having controlling interest in the management of the complete perioperative pathway. Secondly, and largely as a result of the above, there is a major selection bias as to who receives outpatient TJA. In all cases, the patients are younger, fitter, and with less comorbidities. Patients reported in the published literature on outpatient TJA therefore do not represent the average patient that the average surgeon would operate on. Recall, TJA patients are becoming heavier and older patients (85+) are also receiving TJA at increasing rates. It is useful to remember that TJA is a stressful event from a physiological perspective for the patient. Serious complications, including death, can and do occur. Further, some significant events, like cardiac ischemia occur around the second to third day postoperatively. These patients often require medical intervention for stabilization and need readmission when sent home before these events occur. This obviously is not a trivial issue given the penalties applied to hospitals in the US for early readmissions after TJA. The fundamental questions at this early stage of outpatient TJA are 1) whether it is scalable to a larger audience, and 2) whether or not processes can be developed to make it a routine, standard of care. Given that the current literature is limited and written by expert surgeons on a highly select group of patients, and given that patients in general are getting older and less healthy, it is difficult to imagine a future of TJA as drive through surgery

Introduction. The proportion of arthroplasties performed in the ambulatory setting has increased substantially. However, concerns remain regarding whether same-day discharge may increase the risk of complications. The purpose of this study was to compare 90-day outcomes between inpatients and patients having surgery at an ambulatory surgery center (ASC). Methods. Among a single-surgeon cohort of 721 patients who underwent arthroplasty at a free-standing ASC, 611 (84.7%) were matched one-to-one to inpatients based on age, gender, American Society of Anesthesiologists (ASA) score, and Body Mass Index (110 patients could not be adequately matched). The cohort included 208 total hip arthroplasties (34.0%), 196 total knee arthroplasties (32.1%), 178 unicompartmental knee arthroplasties (29.1%), 25 hip resurfacings (4.1%), two revision hip arthroplasties (0.3%) and two revision knee arthroplasties (0.3%). Post-operative outcomes including readmissions, reoperations, unplanned clinic visits, emergency department visits, and complications were compared. Complications were classified as either major (i.e. death, periprosthetic joint infection, pulmonary embolism) or as minor (i.e. delayed wound healing, rashes, urinary retention). Results. The inpatient and outpatient groups were similar in all demographic variables, reflecting successful matching. The rates of any complications (4.1% outpatient vs. 5.1% inpatient, p=0.41), minor complications (2.6% vs. 3.4%; p=0.40), readmissions (1.6% vs. 2.0%; p= 0.67), reoperations (0.7% vs. 1.1%; p=0.36), and unplanned clinic visits (5.4% vs 6.7%; p=0.34) were all lower amongst the outpatient group but did not reach significance with the sample size studied. The rate of major complications was the same in both groups (1.6% for both; p=1.0) while patients who underwent surgery at an ASC had significantly fewer emergency department visits (1.0% vs. 3.1%; p=0.009). Conclusions. Arthroplasty performed in the ambulatory setting appears to be safe in properly selected patients. However, this finding may be partly due to selection bias and intangible characteristics that were not adequately controlled for through matching

Total hip arthroplasty (THA) continues moving to the outpatient arena, and may be feasible for some conversion and revision scenarios. Controversy surrounds appropriate patient selection. The purpose of this study is to report complications associated with outpatient revision and conversion THA, and to determine if comorbidities are associated with complications or overnight stay. From June 2013 through March 2018, 43 patients (44 hips) underwent conversion (n=12) or revision (n=32) THA at a free-standing ambulatory surgery center. Mean patient age was 58.4 years, and 52% of patients were male. Conversion procedures were for failed resurfacing in two, failed hemiarthroplasty in one, and failed fracture fixation with retained hardware in 9. Revision procedures involved head only in one, head and liner in 20, cup and head in 7, stem only in 2, and stem and liner in 2. Forty-four (93%) were discharged same day without incident, none required transfer to acute facility, and 3 required overnight stay with 2 of these for convenience and only one for a medical reason, urinary retention. Three patients with early superficial infection were successfully treated with oral antibiotics. There were no major complications, readmissions, or subsequent surgeries within 90 days. One or more major comorbidities were present in 17 patients (39%) including 1 valvular disease, 8 arrhythmia, 2 thromboembolism history, 3 obstructive sleep apnea, 6 chronic obstructive pulmonary disease, 2 asthma, 4 frequent urination, and 1 renal disease. The single patient who stayed overnight for a medical reason had no major medical comorbidities. Outpatient arthroplasty, including revision THA in some scenarios, is safe for many patients. Presence of medical comorbidities was not associated with risk of complications. The paradigm change of patient education, medical optimization, and a multimodal program to mitigate risk of blood loss and reduce need for narcotics facilitates performing arthroplasty safely in an outpatient setting

To progress to a same day surgery program for arthroplasty, it is important that we examine and resolve the issues of why patients stay in the hospital. The number one reason is fear and anxiety of the unknown and of surgical pain. The need for hospital stay is also related to risk arising from comorbidities and medical complications. Patients also need an extended stay to manage the side effects of our treatment, including after effects of narcotics and anaesthesia, blood loss, and surgical trauma. The process begins pre-operatively with an appropriate orthopaedic assessment of the patient and determination of the need for surgery. The orthopaedic team must motivate the patient, and ensure that the expectations of the patient, family and surgeon are aligned. In conjunction with our affiliated hospitalist group that performs almost all pre-admission testing, we have established guidelines for patient selection for outpatient arthroplasty. The outpatient surgical candidate must have failed conservative measures, must have appropriate insurance coverage, and must be functionally independent. Previous or ongoing comorbidities that cannot be optimised for safe outpatient care may include: congestive heart failure, or valve disease; chronic obstructive pulmonary disease, or home use of supplemental oxygen; untreated obstructive sleep apnea with a BMI >40 kg/m2; hemodialysis or severely elevated serum creatinine; anemia with hemoglobin <13.0 g/dl; cerebrovascular accident or history of delirium or dementia; and solid organ transplant. Pre-arthroplasty rehabilitation prepares the patient for peri-operative protocols. Patients meet with a physical therapist and are provided with extensive educational materials before surgery to learn the exercises they will need for functional recovery. Enhancement of our peri-operative pain management protocols has resulted in accelerated rehabilitation. The operative intervention must be smooth and efficient, but not hurried. Less invasive approaches and techniques have been shown to decrease pain, reduce length of stay, and improve outcomes, especially in the short term. Between June 2013 and December 2015, 1957 primary knee arthroplasty procedures (1010 total, 947 partial) were performed by the author and his 3 associates at an outpatient surgery center. Seven percent of patients required an overnight stay, with a majority for reasons of convenience related to travel distance or later operative time. Importantly, no one has required overnight stay for pain management. Outpatient arthroplasty is safe, it's better for us and our patients, and it is here now. In an outpatient environment the surgeon actually spends more time with the patients and family in a friendly environment. Patients feel safe and well cared for, and are highly satisfied with their arthroplasty experience

Introduction. Over the past several decades, numerous surgical procedures have been perfected in the inpatient hospital setting and then evolved into outpatient procedures. This has been shown to be a safe and economical transition for many orthopedic procedures. A prime example is ACL reconstruction. We report here our early experience with our initial consecutive series of outpatient UKA's done in a free standing ASC (ambulatory surgery center). Materials and Methods. From 8/26/2008 to 5/20/12 there were 60 UKA's performed as outpatient procedures at a free standing ASC. Average patient age was 57.7 years (range of 46–69). Medical comorbidities included 22 patients with HTN and 7 with diabetes. All patients had general anesthesia with periarticular injection of the involved knee (25 cc's of Marcaine with epinephrine 1:100,000) and an intraarticular injection after closure of the capsule with 25 cc of Marcaine with epinephrine mixed with 5 cc of morphine sulfate. Patients without allergy to sulfa were given 200mg of Celebrex bid for three days and hydrocodone/acetaminophin 10/325 1–2 tabs q4 hours prn pain. Patients were discharged home when stable, ambulating with aids as needed, with length of stay ranging from 60–180 minutes (average of 85 minutes). Results. No patients required admission to the hospital for any reason. There was one hemarthrosis in a medial UKA which developed on postoperative day 4. There was uneventful resolution of this event with conservative management and an excellent result was achieved. The vast majority of patients were ambulating well and without walking aids at the 2 week postoperative evaluation. The total number of UKAs performed by the author in the ASC since 8/26/2008 is now 282, still without any complications requiring admission to the hospital. Conclusion. Outpatient UKA performed in an ambulatory surgery center was found to be a safe, efficient, and effective method for the management of unicompartmental osteoarthritis of the knee in this relatively healthy cohort of patients. It is now our routine approach for patients undergoing UKA, with inpatient hospitalization being reserved for those patients who are at higher postoperative risk due to multiple medical comorbidities

Introduction. Traditionally an inpatient hospital stay has been required for all joint replacement surgery. The three primary drivers of cost for joint replacement have been implant cost, other hospital charges and postoperative rehabilitation costs. The three primary reasons that have made hospitalization necessary are pain control, therapy and possible transfusion. Advances in surgical technique, implants, comprehensive blood management, and multimodal pain management have allowed a marked reduction in the hospital stay required, eliminated the need for extensive formal rehabilitation. The purpose of this study is to evaluate if hip resurfacing can be performed safely and cost-effectively as an outpatient procedure. Methods. We present the short-term outcome of our first 77 hip resurfacings done as an outpatient procedure performed by two experienced surgeons. Young patients without major medical co-morbidities were selected. The average age was 53±6 years old (range: 38 to 66), there were 57 men and 20 women. The mean ASA score was 1.6±0.5 (range 1 to 2). The diagnosis was OA in 56, dysplasia in 17, avascular necrosis in 2, and others in 2. Results. All patients were successfully discharged on the day of surgery from our physician-owned outpatient surgery center. There were no major complications noted in the first 6 weeks postoperative. There was one ER visit, and there were no hospitalizations required. The average and highest pain score for each day was shown in Figure 1 for the first 5 days postoperative. Three patients required a morphine injection after discharge from the surgery center. No patients required a transfusion. The cost comparison is obtained from the Blue Cross website which indicates that the “120 day episode of care” cost for hip replacement was $35,000 at Providence, $ 45,000 at Palmetto, $65,000 at Lexington hospital, while cost at our surgery center was $26,000. This represents a cost savings for the insurance company of nearly $9,000 (26%) compared to the lowest cost and $39,000 (60%) compared to the highest cost hospital in our region. Conclusion. We conclude that in properly selected patients, outpatient hip resurfacing can be accomplished safely, with a high degree of patient satisfaction and a tremendous cost savings to the insurer. We suspect that indications can be gradually expanded to allow more patients to take advantage of this option. If insurers could find creative ways to incentivize patients to take advantage of the highest quality, lowest cost options, tremendous health care savings are possible in a free-market health care model free of excessive government regulations and price controls

INTRODUCTION. The benefits of combining enhanced recovery after surgery (ERAS) interventions with an outpatient THA/TKA program are uncertain. The primary objective was to compare adverse event rate and secondly to compare pain management, functional recovery, PROMs and patients' satisfaction. METHODS. We conducted an ambidirectional single subject cohort study on 48 consecutive patients who experienced both a standard-inpatient and an ERAS-outpatient THA/TKA (contralaterally). We compared complications according to Clavien-Dindo scale and Comprehensive Complications Index (CCI), and unplanned episodes of care. Postoperative pain assessed with a numeric rating scale, opioid consumption in morphine milligram equivalents, functional recovery, patient-reported outcome measures (WOMAC, KOOS, HOOS, Forgotten Joint Score and Patient Joint Perception) and patients' satisfaction were also evaluated. RESULTS. Following the ERAS-outpatient surgery, complication rates were reduced by more than 50% (2.1 vs 4.4, p<0.001), CCI was significantly lower (12.3 vs 19.1, p<0.001), and similar unplanned episodes of care were observed (p>0.999). In the first 8 postoperative hours, perceived pain was similar (p>0.805) while opioid consumption was significantly reduced with ERAS-outpatient care (9.3 vs 26.5 MME, p<0.001). Patients walked, climbed stairs, showered, performed activities of daily living, practised sports, went back to work sooner after ERAS-outpatient surgery (p<0.001), but PROMs were similar between groups at the last follow-up (p> 0.188). Patients were more satisfied with hospital stay, pain management, functional recovery, wound management, and overall experience of the ERAS-outpatient pathway and recommended it significantly more (p <0.002). DISCUSSION. Most studies comparing outpatient to inpatient programs conclude that outpatient surgeries did not increase complication or readmission rates, and, overall, were not inferior. We found that compared to std-inpatient practice, ERAS-outpatient program reduced complications by half while not resulting in more unplanned episodes of care. Moreover, it resulted in similar pain relief with fewer opioids, faster early functional recovery and higher satisfaction. Patients were significantly more inclined to recommend the ERAS-outpatient pathway after having personally experienced both outpatient and inpatient protocols. These finding are likely multifactorial and linked to the specific ERAS interventions. CONCLUSION. Results of this study highlight the importance of following ERAS principles when implementing an outpatient THA/TKA program

To progress to a same day surgery program for arthroplasty, it is important that we examine and resolve the issues of why patients stay in the hospital. The number one reason is fear and anxiety for the unknown and for surgical pain. The need for hospital stay is also related to risk arising from comorbidities and medical complications. Patients also need an extended stay to manage the side effects of our treatment, including after-effects of narcotics and anesthesia, blood loss, and surgical trauma. The process begins pre-operatively with an appropriate orthopaedic assessment of the patient and determination of the need for surgery. The orthopaedic team must motivate the patient, and ensure that the expectations of the patient, family and surgeon are aligned. In conjunction with our affiliated hospitalist group that performs almost all pre-admission testing, we have established guidelines for patient selection for outpatient arthroplasty. The outpatient surgical candidate must have failed conservative measures, must have appropriate insurance coverage, and must be functionally independent. Previous or ongoing comorbidities that contraindicate the outpatient setting include: cardiac – prior revascularization, congestive heart failure, or valve disease; pulmonary – chronic obstructive pulmonary disease, or home use of supplemental oxygen; untreated obstructive sleep apnea – BMI >40 kg/m2; renal disease – hemodialysis or severely elevated serum creatinine; gastrointestinal – history or post-operative ileus or chronic hepatic disease; genitourinary – history of urinary retention or severe benign prostatic hyperplasia; hematologic – chronic Coumadin use, coagulopathy, anemia with hemoglobin <13.0 g/dl, or thrombophilia; neurological – history of cerebrovascular accident or history of delirium or dementia; solid organ transplant. Pre-arthroplasty rehabilitation prepares the patient for peri-operative protocols. Patients meet with a physical therapist and are provided with extensive educational materials before surgery to learn the exercises they will need for functional recovery. Enhancement of our peri-operative pain management protocols has resulted in accelerated rehabilitation. The operative intervention must be smooth and efficient, but not hurried. Less invasive approaches and techniques have been shown to decrease pain, reduce length of stay, and improve outcomes, especially in the short term. In 2014, 385 primary partial knee arthroplasty procedures (7 patellofemoral replacement, 13 lateral, and 365 medial) were performed by the author and his 3 associates at an outpatient surgery center. Of those, 348 (95%) went home the same day while 17 (5%) required an overnight stay, with 11 for convenience related to travel distance or later operative time and 6 for medical issues. Outpatient arthroplasty is safe, it's better for us and our patients, and it is here now. In an outpatient environment the surgeon actually spends more time with the patients and family in a friendly environment. Patients feel safe and well cared for, and are highly satisfied with their arthroplasty experience

Reconfiguration of elective orthopaedic surgery presents challenges and opportunities to develop outpatient pathways to reduce surgical waiting times. Dupuytren's disease (DD) is a benign progressive fibroproliferative disorder of the fascia in the hand, which can be disabling. Percutaneous-needle-fasciotomy (PNF) can be performed successfully in the outpatient clinic. The Aberdeen hand-service has over 10 years' experience running dedicated PNF clinics. NHS Grampian covers a vast area of Scotland receiving over 11749 referrals to the orthopaedic unit yearly. 250 patients undergone PNF in the outpatient department annually. 100 patients who underwent PNF in outpatients (Jan2019–Jan2020). 79M, 21F. Average age 66 years range (29–87). 95 patients were right hand dominant. DD risk factors: 6 patients were diabetic, 2 epileptic, 87 patients drank alcohol. 76 patients had a family history of DD. Disease severity, single digit 20 patients, one hand multiple digits in 15 patients, bilateral hands in 65 patients of which 5 suffered form ectopic manifestation suggestive of Dupuytren's diasthesis. Using Tubiana Total flexion deformity score pre and post fasciotomy. Type 1 total flexion deformity (TFD) between 0–45 degrees pre PNF n=60 post N= 85, Type 2 TFD 45–90 degrees pre PNF n=18 post N=9, Type 3 TFD 90–135 pre PNF n=15 post N= 5, Type 4 TFD >135 pre PNF n=1 post PNF N=1. Using Chi-square statistical test, a significant difference was found at the p<0.05 between the pre and post PNF TFD. Complication: 8 recurrence, 1 skin tear. No patients sustained digital nerve injury. Outpatients PNF clinics are a valuable resource

Introduction. Venous thromboembolism (VTE), defined as either pulmonary embolism (PE) or deep venous thrombosis (DVT), is a rare, but serious complication following total hip arthroplasty (THA). Current VTE guidelines recommend pharmacologic agents with or without intermittent pneumatic compression devices (IPCDs). At our institution, both 81mg aspirin (ASA) twice a day (BID) and portable IPCDs were prescribed to THA patients at standard risk for VTE. The aim of this study is to determine if discontinuing the use of portable outpatient IPCDs is safe and does not increase the rate of VTE in patients undergoing THA. Methods. A retrospective review of 1,825 consecutive THA cases was conducted identifying patients with a VTE 90-days postoperatively. Patients were divided into two separate consecutive cohorts. Cohort one consisted of THA patients who received outpatient IPCDs for a period of 14 days (control). Cohort two consisted of THA patients without outpatient IPCDs (experimental). Patients were non-randomized to 81mg ASA BID for 28 days for VTE chemoprophylaxis. An interim power analysis was performed to determine the proper sample size. Results. A total of 748 patients were discharged with outpatient IPCDs while 1,077 patients were discharged without IPCDs. There were no VTE events found in control group (0%). The total VTE rate of the experimental group was 0.2% (2 PE and 1 DVT). There was no statistical difference between these rates (p=0.24). A binary logistic regression did not detect any significant associations for any VTE outcomes even after accounting for demographic differences. Conclusion. Our findings suggest that discontinued use of outpatient portable IPCDs is safe and does not increase the rate of VTE in standard risk patients undergoing THA while using 81mg ASA BID as VTE prophylaxis

Purpose. Traditionally, an inpatient hospital stay has been required for joint replacement surgery. The three primary drivers of cost for joint replacement have been implant cost, other hospital charges and postoperative rehabilitation costs. The three primary reasons that have made hospitalization necessary are pain control, blood loss / transfusion, and monitoring patients with comorbidities. Advances in surgical technique, implants, comprehensive blood management, and multimodal pain management have allowed a marked reduction in the hospital stay required and have eliminated the need for extensive formal rehabilitation. The purpose of this study is to evaluate if hip resurfacing can be performed safely and cost-effectively as an outpatient procedure. Methods. We present the short-term outcome of our first 125 hip resurfacings done as an outpatient procedure performed by two experienced surgeons. Young patients without major medical co-morbidities were selected. The average age was 53±7 years old (range: 38 to 66), there were 98 men and 27 women. The mean ASA score was 1.7±0.5 (range 1 to 3). The diagnosis was OA in 92, dysplasia in 22, and osteonecrosis in 9, and trauma in 2. There were no major complications noted in the first 6 weeks postoperative. There was one ER visit, and there were no hospitalizations required. Results. The average and highest pain score for each day was shown in Figure 1 for the first 5 days postoperative. Three patients required a morphine injection after discharge from the surgery center. No patients required a transfusion. The satisfaction survey showed: The cost comparison is obtained from the Blue Cross website which indicates that the “120 day episode of care” for total hip arthroplasty is $35,000, $ 45,000, and $65,000 at the three local hospitals, while cost at our surgery center was $26,000. This represents a cost savings for the insurance company of nearly $9,000 (26%) compared to the lowest cost and $39,000 (60%) compared to the highest cost hospital in our region. Conclusion. We conclude that in properly selected patients, outpatient hip resurfacing can be accomplished safely, with a high degree of patient satisfaction and a tremendous cost savings to the insurer. We suspect that indications can be gradually expanded to allow more patients to take advantage of this option. If insurers could find creative ways to incentivize patients to take advantage of the highest quality lowest cost options, tremendous health care savings are possible in a free-market health care model free of excessive government regulations and price controls

This paper reports the cost of outpatient venous thromboembolism (VTE) prophylaxis following 388 injuries of the lower limb requiring immobilisation in our institution, from a total of 7408 new patients presenting between May and November 2011. Prophylaxis was by either self-administered subcutaneous dalteparin (n = 128) or oral dabigatran (n = 260). The mean duration of prophylaxis per patient was 46 days (6 to 168). The total cost (pay and non-pay) for prophylaxis with dalteparin was £107.54 and with dabigatran was £143.99. However, five patients in the dalteparin group required nurse administration (£23 per home visit), increasing the cost of dalteparin to £1142.54 per patient. The annual cost of VTE prophylaxis in a busy trauma clinic treating 12 700 new patients (2010/11), would be £92 526.33 in the context of an income for trauma of £1.82 million, which represents 5.3% of the outpatient tariff. Outpatient prophylaxis in a busy trauma clinic is achievable and affordable in the context of the clinical and financial risks involved. Cite this article: Bone Joint J 2013;95-B:673–7

Refinement of surgical techniques, anesthesia protocols, and patient selection has facilitated this transformation to same day discharge for arthroplasty care, most notably Partial Knee Arthroplasty (PKA). The trend for early discharge has already happened for procedures formerly regarded as “inpatient” procedures such as upper extremity surgery, arthroscopy, ACL reconstruction, foot and ankle procedures, and rotator cuff repair. Our program began focused on PKA and has now expanded to primary TKA and THA, and select revision cases. Over the past few years we have performed 1,230 knee arthroplasty procedures with no readmissions for pain control. Average age and age range is identical to our inpatient cohort for our partial knee cases. Patient selection is based on medical screening criteria and insurance access. PKA is the ideal procedure to begin your transition to the outpatient space. We currently perform medial PKA, lateral PKA, and patellofemoral arthroplasty as an outpatient. The program centers on the patient, their family, home recovery, preoperative education, efficient surgery, and represents a shift in the paradigm of arthroplasty care. It can be highly beneficial to patients, surgeons, anesthesia, facility costs, and payors as arthroplasty procedures shift to the outpatient space. Perhaps the most significant developments in joint replacement surgery in the past decade have been in the area of multimodal pain management. This has reduced length of stay in the inpatient hospital environment opening the opportunity for cost savings and even outpatient joint replacement surgery for appropriately selected patients. The hallmark of this program is meticulous protocol execution. Preemptive pain control with oral anti-inflammatory agents, gabapentin, regional anesthetic blocks that preserve quad function for TKA (adductor canal block) and pericapsular long acting local anesthetics with the addition of injectable ketorolac and IV acetaminophen are key adjuncts. Over the past two years utilizing this type of program over 60% of our partial knee replacement patients are now returning home the day of surgery. Concerns over readmission are appropriate. The rates of complications and readmissions are less than our inpatient cohort in appropriately selected cases with a standardised care map. We believe this brings the best VALUE to the patients, surgeons, and the arthroplasty system

Aim: To investigate the magnitude of revenue lost by the Department of Trauma and Orthopaedics at Ports-mouth Hospitals NHS Trust in 2007 as a result of providing outpatient viscosupplementation joint injections. Methods: Data was collated on all outpatient intra-articular hyaluronic acid viscosupplementation performed by our department in 2007. Information on existing HRG tariffs for orthopaedic outpatient attendances as well as clinical coding of joint injections by our department was also gathered. Results: The 2007/2008 tariffs for orthopaedic outpatient first and follow-up appointments were £147 and £73 respectively for adults, and £157 and £85 respectively for children (under 17 years of age). No additional mandatory tariff currently exists for joint injections performed in the outpatient setting. During our study period, the cost of a dose of viscosuplementation (Hyaluronic acid 60mg/ 3 ml) varied between £213 and £248. A total of 812 doses of viscosupplementation were administered to outpatients by our department resulting in pharmaceutical costs of £175,126. Only 751 cases of outpatient appointment with joint injection (all types) were recorded and coded by the department. Conclusions:. As long as no mandatory DoH tariff exists for out-patient joint injections, outpatient viscosupplementation remains an expensive service for trusts to provide and may warrant rationalisation. Under Payment by Results it is imperative that the quality of data capture and clinical coding improve, if trusts are to maximise financial gains. Clinicians need to be made more aware of the processes and implications of Payment by Results. In order for trusts to receive fair remuneration it is essential that reasonable national tariffs be set for all types of procedure or service delivered

Objectives. “Virtual fracture clinics” have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a “top-down” analysis of the cost effectiveness of this virtual fracture clinic pathway. Methods. National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign. Results. The total staffing costs rose by 4% over the time period (from £1 744 933 to £1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of £212 705 would have been required for staffing costs. Conclusions. The virtual fracture clinic system was associated with less overall use of staff resources in comparison to national cost data. Adoption of this system nationally may have the potential to achieve significant cost savings. Cite this article: P. J. Jenkins.

Purpose. To analyse the effectiveness of using outpatient management of paediatric bone and joint infections with parenteral antibiotic therapy in terms of its efficacy, safety and cost-effectiveness compared to prolonged inpatient treatment. Method. Paediatric cases of septic arthritis or osteomyelitis were identified over a seven year (2004–2011) period in a regional teaching hospital. This included patients either treated as long-term inpatients or given outpatient parenteral antibiotic therapy. The outcome measures recorded included: whether treatment was successful, complications, and length of hospital stay. A cost analysis was also calculated. Results. A total of 41 paediatric patients diagnosed with osteomyelitis or septic arthritis were reviewed, of which 8 were treated as inpatients during the course of their IV antibiotic therapy, and 33 were treated with outpatient parenteral antibiotic therapy (requiring a PICC line to be in situ). The mean length of hospital stay for the inpatient group was 23 days, compared to 3.9 days for the outpatient group. The cost saving in terms of hospital stay is (19 × £464=) £8816. Treatment was effective in all groups. In terms of complications of therapy, there was 1 antibiotic-related case in the inpatient group, and 4 cases in the outpatient group of which 3 related to antibiotic side-effects and 1 related to the PICC line. Conclusion. Outpatient treatment of paediatric bone and joint infections is both clinically and cost effective when compared to long stay inpatient management. It is safe, well tolerated and we advocate its adoption, wherever resources allow

Pulmonary embolism is a serious complication after arthroscopy of the knee, about which there is limited information. We have identified the incidence and risk factors for symptomatic pulmonary embolism after arthroscopic procedures on outpatients. The New York State Department of Health Statewide Planning and Research Cooperative System database was used to review arthroscopic procedures of the knee performed on outpatients between 1997 and 2006, and identify those admitted within 90 days of surgery with an associated diagnosis of pulmonary embolism. Potential risk factors included age, gender, complexity of surgery, operating time defined as the total time that the patient was actually in the operating room, history of cancer, comorbidities, and the type of anaesthesia. We identified 374 033 patients who underwent 418 323 outpatient arthroscopies of the knee. There were 117 events of pulmonary embolism (2.8 cases for every 10 000 arthroscopies). Logistic regression analysis showed that age and operating time had significant dose-response increases in risk (p < 0.001) for a subsequent admission with a pulmonary embolism. Female gender was associated with a 1.5-fold increase in risk (p = 0.03), and a history of cancer with a threefold increase (p = 0.05). These risk factors can be used when obtaining informed consent before surgery, to elevate the level of clinical suspicion of pulmonary embolism in patients at risk, and to establish a rationale for prospective studies to test the clinical benefit of thromboprophylaxis in high-risk patients

Magnetic resonance imaging (MRI) continues to become more widely accessible as an investigation, with an increasing number of scans being performed in the outpatient setting for suspected shoulder pathology. We performed a retrospective review of all shoulder MRI scans performed in an orthopaedic outpatient setting in a district general hospital between October 2010 and October 2011. We also reviewed the medical notes for these patients. 75 MRI Shoulder scans were performed on 74 patients. In 5 cases (7%), no other form of imaging was performed prior to MRI scan. 11 patients (15%) had no provisional diagnosis included in the referral. The nature of referral, indication for MRI and subsequent management of these patients was also examined. Our findings may support the use of guidelines for requesting MRI scans of the shoulder in outpatients

Aims: Outpatient clinic follow-up of patients after knee arthroscopy is routine practice in many orthopaedic units. It can be inconvenient and expensive for patients and may be unnecessary.The aim of our study was to compare oupatient follow-up with telephone follow-up after knee arthroscopy in a prospective randomised trial. Patients and method: Over a four-month period, 50 patients (mean age 41 years) were included in our study. Each patient underwent a day-case knee arthroscopy as previously planned. After surgery, each patient was randomised to either attend for an outpatient clinic follow-up after two weeks or to receive a telephone follow-up after two weeks from operation. All patients were assessed after four weeks from surgery by an independent assessor who was blinded to the type of follow-up each patient had received. No patients in the study were lost to follow-up. Results: No significant difference was found in patient satisfaction scores between the outpatient and telephone groups (mean 7.78 vs mean 7.92). However, 81% patients in the telephone group and 57% patients in the clinic group (p< 0.01) preferred telephone follow-up if they were to undergo another knee arthroscopy. There was a significant increase in patello-femoral problems in those preferring outpatient follow-up (64%) compared to telephone follow-up (24%), p< 0.05. No difference in complication rates between the two groups was found. Conclusion: Telephone follow-up provides a satisfactory and safe alternative to outpatient follow-up after knee arthroscopy. It is preferred by the majority of patients and could relieve pressure on outpatient resources

Background:. Developing a successful outpatient service for Ilizarov frame removal provides both patient and cost benefits. Misinformation and patient trepidation can be detrimental to recovery and influence choices. Education may play an important role in tailoring an efficacious service. Objective:. Review Belfast Regional Limb Reconstruction frame removal practice, introduce changes aimed at improving care and evaluate effects. Methods:. 1 year retrospective review of Ilizarov frame removal. Evaluation of service prior to and following provision of a new patient information leaflet, alongside a test wire removal technique. Subsequent service evaluation supplemented via patient reported feedback questionnaire. Results:. Retrospectively 85% Ilizarov frames removed in clinic, 54% required Entonox. Annual cost £19000. 46% patients unaware of process, gathering information from unprofessional sources. General anaesthetic and analgesic requirements related to psychosocial influences; no correlation between fracture configuration, elective reconstructive cases and operative techniques. Prospectively 96% patients found information leaflet educational and beneficial. 87% Ilizarov frames removed in clinic. 100% patients who had outpatient removal recommend this method. Entonox use reduced to 15% with average pain score 4.6/10 without analgesia. Patients felt happier. Projected annual cost savings £3000. 100% rated service excellent. Discussion:. Professional education and a standardised outpatient removal process for Ilizarov frames, delivered by a dedicated specialist team, reduces morbidity and positively impacts service provision

Low molecular weight heparin (LMWH) is frequently used as thromboprophylaxis after major orthopaedic surgery. Varying levels of non-adherence (5% to 45%) with outpatient LMWH has been reported. Oral direct thrombin inhibitors have been recommended by industry due to ease of administration. We aim to audit the compliance rate with outpatient LMWH treatment following primary total hip arthroplasties (THA) in our district general hospital (DGH). Using the ORMIS computer system, we identified all primary THA performed in Monklands Hospital between July 2011 and August 2012. Patients’ case notes were analysed retrospectively, looking at operating surgeon's postoperative thromboprophylaxis instructions. We then conducted a telephone interview on patients discharged with outpatient LMWH to assess compliance. There were 58 primary THAs performed during the audit period. 33 patients were discharged on outpatient LMWH, whilst 15 patients and 3 patients were discharged on aspirin and warfarin respectively. Seven patients were excluded as their discharge prescriptions were missing. We successfully contacted 20 of the 33 patients discharged with outpatient LMWH. All respondents showed 100% compliance to the full course of treatment. 50% of patients self-administered; 30% were administered by district nurses and 20% by family members. 35% of patients preferred an oral tablet alternative, for its perceived ease of administration. Bruising and skin irritation were the reported problems in some patients, but these did not affect compliance. Contrary to the previous published non-adherence rates, the compliance rate with outpatient LMWH after THA was high in our DGH. The patient counseling, and family/district nurse involvement in may have contributed to this. However, our numbers of patients are low but data collection continues

Introduction. There has been a recent surge in the interest of the role of vitamin D in chronic musculoskeletal pain however there are limited studies that have investigated the link of vitamin D hypovitaminosis with low back pain. The aim of our study was to determine the prevalence of low vitamin D levels in patients who present with low back pain in an outpatient setting in the UK. Methods. Data was collected retrospectively from computerised databases of all patients who presented with low back pain from a single spinal consultant's outpatient clinic and have had serum levels of 25-hydroxycholecalciferol (25-OH vitamin D) requested. Data of these patients were collected from hospital electronic and paper records and analysed against their serum 25-OH vitamin D levels. Results. Data on 229 patients was collected over an 18 month period. 19.7% of patients presenting to the spinal outpatient clinics had severe 25-OH vitamin D deficiency (less than 15 nmol/L) compared to 2.6% of 3132 non-spinal outpatient clinic patients (p<0.001). However, the percentage of patients with deficient (15 to 30 nmol/L) but not severe deficiency was similar in both groups (37.6% versus 38.3%). There was no significant difference in the incidence of vitamin D deficiency whether a surgical or non-surgical pathology was present or not (p=0.62). Conclusion. We have found no link between vitamin D deficiency and low back pain in this study. Vitamin D deficiency is a common comorbidity in Leicester

Purpose: Unicompartmental replacement for medial compartment arthrosis of the knee has become popular with eligible patients because of the shortened recovery time, decreased tissue damage and easier future revision. Contemporary multimodal anesthesia has added the potential to safely perform this as outpatient surgery reducing inpatient bed burden. We describe our initial pilot experience with this approach. Method: The first 25 patients who fulfilled the criteria developed underwent same day surgery for unicompart-mental arthroplasty for medial (19) or lateral (3) compartment replacement with either the Oxford knee (20) or the Uniglide (2). All patients were treated with an indwelling femoral nerve catheter supplied by Ropivacaine through a constant release pump (Stryker) which was discontinued at 48 hours. Home care support was made available in first 72 hours by way of RN and physiotherapy visits and mandatory use of walker or crutches for the first 48 hours. Results: Patients in this cohort were universally very satisfied with the model of postop care as described and particularly pleased to avoid a hospital stay. Eighty percent of those who were offered this model chose it. The use of narcotic oral medication was consistently about 50% less than that observed to similar inpatients treated without catheter, and eight patients had complete opioid sparing experience. There were no complications related to the catheter, in particular serious falls or longer term neurologic sequelae. The clinical results were very good and equal to those who were in patients. Conclusion: Outpatient unicompartmental replacement can be performed safely recognizing the decreased surgical trauma and pain stimuli associated with UKR and a relatively younger and healthier cohort screened for this alternative. These patients are amongst the most satisfied with their perioperative course and all would do the same again if given the chance. Other models of analgesia could be considered, though the catheter does seem to have a large opioid sparing effect that likely contributed to patient well being and satisfaction

Purpose: The purpose of this study was to demonstrate the feasibility and early outcomes of one- and two-level lumbar decompression performed as an outpatient procedure. Methods: A retrospective review was performed comparing lumbar “laminoplasty” (bilateral decompression from a unilateral approach) using a minimally invasive (MIS-group) technique (MetRxTM tubular retractor system) to open laminoplasty (Open Group). Comparison between groups was performed for patient demographics, radiographic and operative parameters, postoperative pain (VAS), analgesic use and adverse events. Results: A total of 67 (Open–n=37/ MIS-n=30 [n=20: out patients] patient with a minimum follow-up of 6 months were analyzed. There was no statistically significant difference between groups for age, sex, BMI and radiographic parameters. The MIS group demonstrated a statistically significant reduction (mean = 24minutes) in operative time, estimated blood loss (63mls vs. 227mls), recovery room VAS scores (1.4 vs. 4.4) and total analgesic requirements by %50. None of the MIS group procedures performed on an outpatient basis required readmission. The length of stay for the n=10 inpatient MIS group (elderly patients) was also reduced compared to the open group (2.6 vs. 4.7 days, P= 0.035). The groups were comparable in operative and postoperative adverse events. No progression of preexisting spondylolisthesis has been noted in either group during the follow-up period. Furthermore, only one patient has required reoperation for mechanical low back pain in the MIS group and one patient for recurrent leg pain in the open group. Conclusions: Minimally invasive outpatient decompression for 1–2 level spinal stenosis is feasible, provides acute perioperative patient and resource utilization benefits and appears to have comparable short-term clinical efficacy compared to open decompression. Long-term follow-up and validated outcomes assessments are currently being assessed. Funding: Commerical funding. Funding Parties: Medtronic-Sofamor Danek

Purpose. Pediatric orthopaedic surgeons encounter referrals from primary care practitioners and pediatricians that are benign in nature or within accepted limitations for physiological musculoskeletal variance. These referrals are believed to be secondary to insufficient pediatric musculoskeletal expertise and consume already limited pediatric orthopaedic resources. To date, our annual CME course dedicated to pediatric musculoskeletal medicine is the only one of its kind in Canada. It includes didactic teaching as well as a clinic of unnecessary referrals in which participants examine patients and receive feedback from consultants. The purpose of this study was to evaluate the impact of a pediatric musculoskeletal CME course on the quality of local outpatient referrals over a four year period. Method. Retrospective chart reviews were performed to evaluate outpatient referrals at a tertiary orthopaedic center over an eight month period prior to the commencement of an annual CME course (2006–2007) and three years following its initiation (2010). 1041 consecutive referrals from the first time period and 1124 consecutive referrals from the second time period were collected. Referrals for normal conditions within physiological tolerance were identified based on the final clinical diagnosis by the consultant orthopaedic surgeon and the scheduled follow up. Results. 872 referrals from the first time period and 1006 referrals from the second time period were provided by primary care practitioners and pediatricians. Prior to the CME course, 27.7% of referrals were for physiological conditions. These referrals were most often associated with specific benign diagnoses: torsional variation (88%) and flexible flatfoot (45%). Three years following the induction of the CME course, referrals for physiological conditions from family physicians decreased by 20.1%. Conclusion. Results from this study suggest that a pediatric musculoskeletal CME course designed for family physicians and pediatricans is an effective method for reducing unnecessary local pediatric orthopaedic referrals. We advocate that additional CME initiatives based on our annual course be implemented in communities across Canada in order to improve patient care and optimize the outpatient referral process

Total joint arthroplasty (TJA) has historically been considered primarily an inpatient operation. However, the actual length of stay (LOS) has diminished over time. At our institution the LOS from 1987 to 1990 averaged five to seven days. This decreased to three days from 1993 to 2002 and down to one to two days from 2005 to 2011. With the adaptation of improved anesthesia and pain management protocols, minimally invasive surgery techniques, rapid recovery protocols, and proper patient selection, outpatient (OP) TJA appears to be the next step in maximizing peri-operative efficiency; especially as younger patients are undergoing TJA. Other potential benefits of OP TJR include improved patient care and control, better patient and surgeon satisfaction and a lower overall cost. Over a twenty-four month period (July 2012 to June 2014) we performed 250 primary TJAs (139 hips and 111 knees) and twelve revision TJAs (six hips and six knees). All patients received 400 mg of celecoxib pre-operation and 200 mg/day for ten days. In addition to general anesthesia, hips received a short-acting spinal and knees received an adductor canal block. Tranexamic acid (IV or topical) and a pericapsular injectable cocktail of liposomal bupivacaine was routinely used. There was one deep infection (0.4%) and one readmission for pain control (0.4%). Two cases of deep vein thrombosis were diagnosed (0.8%). Patient education, home health care utilization, and proper patient selection are key factors to keep hospitalization rates, emergency room visits, and re-admission rates to a minimum

An outpatient total hip arthroplasty (THA) will be defined as a THA performed at an ambulatory care facility where the patient is discharged the same day as the procedure. Such procedures are being done in the United States and the hypothesis is that a “same day” THA will lead to reduced costs and improved outcomes. However, there are no appropriately powered randomised controlled trials evaluating outcomes in this group of patients to support this hypothesis. It appears that a “same day” THA is here to stay. Therefore, the selection criteria for patients that undergo the procedure needs to be carefully defined. The safety of this regimen needs to be confirmed. In an evaluation of the NSQIP database, Otero et al. compared outcomes in patients discharged on POD 0 and POD 1 and noted that THA patients in the POD 0 group had increased rates of complications. Risk factors for complications included age >70, smoking, COPD, CAD and hematocrit less than 36. In addition, the patients discharged on POD 0 had higher rates of diabetes, steroid use and lower hematocrit. Clearly, the selection criteria for this procedure needs to be defined. In two separate studies, Goyal et al. and Dorr et al. noted that approximately 25% of patients were unable to leave the hospital on POD 0 usually because of nausea and/or hypertension. Issues to consider before developing a same day discharge program include: 1) Is the patient healthy enough to go home the same day as the surgery?; 2) Does the patient live close enough to the hospital to be discharged the same day?; 3) Can the family provide the appropriate care for the patient at home?; 4) Is it really better for the patient or just better for the surgeon?. If a surgeon embarks on a same day discharge program, rigorous selection criteria must be instituted and followed. In addition, the patient must have free choice with respect to a same day discharge versus a 24-hour stay

Over the past 30 years there have been many improvements in implant fixation, correction of deformity, improved polyethylene wear, and survival after knee replacement. The work over the last decade has focused on less invasive surgical techniques, multimodal pain management protocols, more rapid functional recovery and reduced length of stay, aiming to minimise the side effects of treatment while maintaining function and implant durability. When combined and standardised these pre-, intra- and post-operative factors have now facilitated outpatient knee replacement procedures for unicompartmental replacement, patella femoral arthroplasty and total knee replacement (TKR). We have found liposomal bupivacaine, with potential for longer therapeutic action, to be a helpful adjunct and describe our current pain management program. The next step in our multimodal program is to improve the duration of patient satisfaction and reduce cost and length of stay after TKR. Cite this article: Bone Joint J 2014;96-B(11 Suppl A):7–9

Purpose: The Bankart procedure is widely studied in the literature. The general lack of postoperative complications is well recognised. The purpose of this work was to study patient comfort after Bankart procedures performed in the outpatient setting in order to validate the feasibility of this approach. Material and methods: Thirty patients underwent Bankart procedure from June 2001 to 2002 performed by the same surgeon in an outpatient clinic. There were 28 men and two women, mean age 28 years. Pain was assessed with a visual analogue scale (VAS) at entry into the recovery room (P0), when leaving the recovery room (P1), on day 1 by telephone (P2), and on day 7 at consultation (P3). On day 1 and day 7, the patient was also asked if he/she preferred staying in hospital one night. The general anaesthesia protocol was the same for all patients. Intraopeartive analgesia was 20 mg nefopam (Acupan(r)) in a half-hour infusion, 2g propacetamol (Prodafalgan(r)) or paracetamol (Perfalgan(r)), and 100 mg ketoprofen (Profenid(r)) if there were no contraindications. In the recovery room, 3 mg morphine was delivered in by iv bolus until the VAS was less than 4/10 followed by oral paracetamol-codeine combination. Home treatment used 200 mg/d ketoprofen and paracetamol+codeine. Results: The only complication was one superficial venous thrombosis of the upper limb diagnosed on day 15. There were no cases of postoperative haematoma or infection. One patient stayed one night in hospital after the procedure due to a vagal malaise which occurred at discharge; the VAS pain score was the same in this patient as in the others. Pain assessment was: D1=2 (5. 0); D2=1 (3, 0). Postoperative comfort was thus considered satisfactory. None of the patients would have preferred 24h hospitalisation. Discussion: There has been only one series of 25 patients reporting results of patient comfort and cost of outpatient Bankart procedure. Patients underwent surgery with a scalene interblock. Three of the 25 patients preferred a 24h hospitalisation because of pain, perhaps due to the rebound pain effect after the block. Absence of drainage did not lead to any case of haematoma, confirming an earlier unpublished study of 50 consecutive patients who underwent classical hospital procedure without drainage. Only one patient had a subcutaneous haematoma that resolve favourably spontaneously. These results suggest that satisfactory patient comfort can be achieved postoperatively for outpatient procedures. We have decided to pursue this approach

The purpose of this study was to retrospectively review the outcomes of percutaneous flexor tenotomies of diabetic claw toes with ulcers or pending ulcers. A retrospective chart review between January 1999 and June 2005 was performed to identify those patients that had undergone a percutaneous flexor tenotomy for diabetic claw toe deformities. Thirty-four toes in fourteen patients were identified. Twenty-four toes had ulcerations at the terminal aspect and three of these had radiographic evidence of osteomyelitis of the terminal phalange. All patients had palpable pulses and good capillary refill. A percutaneous flexor tenotomy was performed in an outpatient clinic on all toes, patients with a rigid flexor contracture at the proximal interphalangeal (PIP) joint underwent an osteoclaysis to correct a portion of the deformity. The average follow-up was thrirteen months, all patients with ulcers healed and there were no significant complications. Those without osteomyelitis healed within an average of three weeks and those with osteomyelitis healed within an average of eight weeks. A Percutaneous flexor tenotomy with osteoclasis of the PIP joint performed in an outpatient clinic is a safe and effective method to off-load the tip of the toe such that ulcer healing can occur. The presence of osteomyelitis is not a contraindication for this technique; however, an increased healing time can be expected

Background Our hospital operates a consultant led rapid review process of X-rays and case notes of patients referred to fracture clinic from Accident & Emergency (A& E) and General Practitioners (GP) on a daily basis. This compares with other centres where patients are reviewed in outpatient fracture clinics soon after injury. Aim Evaluate effectiveness of consultant led rapid review process compared to standard consultant fracture clinics. Patients and Methods Prospective study of the rapid review process over 4 weeks of all patients referred to fracture clinic by A& E and GPs. Total number of patients referred per day, time taken to review these patients case notes and X-rays, number of recalls and reason for recall were documented. This was compared to consultant led fracture clinics, which included time taken to review patients. Results 797 patients were processed through the rapid review over 4 weeks. 53 (6%) patients were recalled, 32 (4%) for a change of management and 21 (2.6%) because of lack of information. The mean number of patients referred per day was 28 taking a mean of 28 minutes; thus the mean time to review one patient was 1.0 minute. The mean number of patients recalled per day was 2. The mean time taken to review a patient in a standard fracture clinic was 11 minutes. Therefore, the total time that would have taken to review 28 patients in the standard fracture clinic would be 308 minutes. Conclusion A consultant led rapid review process of all patients referred to fracture clinic is a very efficient process. Rapid review process saves clinic time and resources, minimises delays in clinical decision-making and saves the patient an unnecessary visit to the outpatient department

This study aimed to evaluate the month-to-month prevalence of antibiotic dispensation in the 12 months before and after total knee arthroplasty (TKA) and total hip arthroplasty (THA) and to identify factors associated with antibiotic dispensation in the month immediately following the surgical procedure.

In total, 4,115 THAs and TKAs performed between April 2013 and June 2019 from a state-wide arthroplasty referral centre were analysed. A cross-sectional study used data from an institutional arthroplasty registry, which was linked probabilistically to administrative dispensing data from the Australian Pharmaceutical Benefits Scheme. Multivariable logistic regression was carried out to identify patient and surgical risk factors for oral antibiotic dispensation.

Oral antibiotics were dispensed in 18.3% of patients following primary TKA and 12.0% of patients following THA in the 30 days following discharge. During the year after discharge, 66.7% of TKA patients and 58.2% of THA patients were dispensed an antibiotic at some point. Patients with poor preoperative health status were more likely to have antibiotics dispensed in the month following THA or TKA. Older age, undergoing TKA rather than THA, obesity, inflammatory arthritis, and experiencing an in-hospital wound-related or other infectious complications were associated with increased antibiotic dispensation in the 30 days following discharge.

A high rate of antibiotic dispensation in the 30 days following THA and TKA has been observed. Although resource constraints may limit routine wound review for all patients by a surgeon, a select cohort may benefit from timely specialist review postoperatively. Several risk factors identified in this study may aid in identifying appropriate candidates for such changes to follow-up care.

Background. The internet has revolutionized the way we live our lives. Over 60% of people nationally now have access to the internet. Healthcare is not immune to this phenomenon. We aimed to assess level of access to the internet within our practice population and gauge the level of internet use by these patients and ascertain what characteristics define these individuals. Method. A questionnaire based study. Patients attending a mixture of trauma and elective outpatient clinics in the public and private setting were invited to complete a self-designed questionnaire. Details collected included basic demographics, education level, number of clinic visits, history of surgery, previous clinic satisfaction, body area affected, whether or not they had internet access, health insurance and by what means had they researched their orthopedic complaint. Results. 292 completed the questionnaire (146 M, 146 F). 17 were incomplete and excluded from final analysis. Multiple logistic regression found younger age (O.R. 2.22 in 20–35 age group), possession of health insurance (O.R. 2.65) and higher levels of education (O.R. 8.22 for tertiary education) were all significantly associated with a higher level of access to the internet. Among those with internet access, a second regression analysis showed that a positive history of surgery (O.R. 2.82) and possession of a trade qualification (O.R. 5.15) were the best predictors of internet use to research one's orthopedic condition. Conclusion. Our study showed a level of access comparable with national statistics. It was consistent with previous studies showing younger and better educated had greater access. We believe that this shows there is a niche for increased information provision for those patients who require surgery, but we must be aware access is not available to everyone in the community

Background: In an effort to reduce the waiting times for outpatient appointments and surgery ‘Direct Access Arthroscopy Services’ have been set up in some centres whereby GP’s assess patients with acute knee injuries. The value of a physiotherapist in the Back Pain clinic is well known, however their effectiveness in an Acute Knee Injury Clinic has not been documented despite the fact that they have already been used in some centres to triage these injuries. Purpose of study: This study was therefore set up to determine if an experienced physiotherapist can accurately diagnose an acute knee injury and formulate a treatment plan. Methods: 50 consecutive patients with acute knee injuries were seen in the fracture clinic. They were each assessed and a diagnosis made and treatment plan formulated by the consultant, an orthopaedic SHO and two experienced physiotherapists in random order. Evaluation was by history, examination and X Rays. Final diagnosis was based on arthroscopic findings, further investigations or response to conservative treatment. Results: We found no statistically significant difference in the clinical diagnosis and treatment plans made by the consultant and the orthopaedic physiotherapist p> 0.05 (Mc Nemar’s Test). In addition the physiotherapist had a higher proportion of correct diagnoses compared to the SHO. Again this difference was not statistically significant. Conclusion: The results suggest that an experienced physiotherapist can safely and effectively be used to assess patients with an acute knee injury in the outpatient clinic setting

Introduction: Shoulder pain, caused by subacromial impingement or rotator cuff tear, is common for the middle-aged and elderly people. It can cause diminished ability to work and prolonged sick-leaves. The purpose of this study was to evaluate the effect of the operative treatment of this pain (arthroscopic subacromial decompression, rotator cuff repair) when the patients returned home the same day (outpatient) from the day-surgery unit or stayed 1–3 nights at the ward (hospitalized). Methods: Ninety-three patients were included in this prospective, comparative study. The inclusion criteria were:. 1) shoulder pain more than 6 months with no response for conservative treatment,. 2) no previous shoulder surgery of the same shoulder or surgery of the contralateral shoulder,. 3) clinically and radiologically diagnosed subacromial impingement or rotator cuff tear. The minimum of the follow-up was 2 years (range 24 to 32 months), and 76 patients (82%) participated to the evaluation at this point. In the outpatient group were 37 patients (24 subacromial impingements, 13 rotator cuff tears), and in the hospitalized group 39 patients (23 subacromial impingements, 16 rotator cuff tears). Evaluation methods were clinical examination, radiographic evaluation, isometric elevation strength measurements, as well as the University of California Los Angeles (UCLA) and Constant shoulder scores. All operations were done by one experienced orthopaedic surgeon, and all evaluations at the follow-up by one independent examiner. Results: At the follow-up, both shoulder scores (UCLA, Constant) were significantly better than the preoperative scores in every patient group (p< 0.001). In the patients with subacromial impingement, muscle strengths of the operated shoulders improved to the level of non-operated, contralateral shoulders, while in the patients with rotator cuff tear, the strength was still diminished (the mean difference in elevation strengths when comparing to the contralateral side was 1.8 kg). However, no significant differences in the shoulder scores or muscle strengths were found when the outpatient group and hospitalized group were compared. Conclusions: Operative treatment of subacromial impingement and rotator cuff tear after failed conservative treatment led to good results at 2-year follow-up. The patients in the outpatient-group had similar results than the patients in the hospitalized patient-group. However, because the hospitalization is more expensive, the outpatient surgery is recommended

Background. Orthopaedic surgeons are increasingly pressured to consider thromboprophylaxis for patients when little evidence exists. The aim of this study was to determine the incidence of fatal pulmonary embolism following office attendance in our outpatient fracture clinic. Methods. Between October 2004 and September 2006 details of all new patients referred to our orthopaedic fracture clinic were prospectively entered into an audit database. Patients did not receive any form of thromboprophylaxis. Data was cross referenced with a national mortality database to identify all patients who subsequently died within 90 days of attendance in fracture clinic. Results. 11,502 new patient fracture clinic appointments occurred during the study period. 5604 patients had lower limb injuries. Twenty three patients died within 90 days of being seen. The mean age of these patients was 75 years (range 52–100). Two of the 23 patients attended fracture clinic with lower limb injuries. Review of the medical records showed no evidence of pulmonary embolism. Assuming a worst case scenario that both died of fatal pulmonary embolism the incidence of fatal pulmonary embolism following attendance in fracture clinic with a lower limb injury is no higher than 0.036% (95% CI 0.09%–0.33%). Conclusion. The incidence of fatal PE following outpatient management of lower limb fractures is very low. This incidence data will inform decisions on the risk-benefit analyisis of thromboprophylaxis in this group of patients

The increase in knee arthroscopy performed on an out-patient basis, along with the need for cost reduction and a safe and rapid patient discharge, has underlined the importance of adequate anaesthesia techniques. We designed this study to compare efficacy, efficiency and surgeon’s satisfaction of total intravenous anaesthesia with propofol and remifentanil with those of spinal or peripheral nerve blocks for outpatient knee arthroscopy. A total of 120 patients undergoing elective outpatient knee arthroscopy were randomly allocated to receive total intravenous anaesthesia with propofol and remifent-anil (n=40), combined sciatic-femoral nerve block (n=40) or spinal anaesthesia (n=40). Preparation times, surgeon’s satisfaction, discharge times and anaesthesia-related costs with the three anaesthesia techniques were analysed. Preparation time was shorter with general anaesthesia (13 min) than with spinal anaesthesia or sciatic-femoral block (15 min; p=0.006). Surgeon’s satisfaction was similar in the three groups. Furthermore, 17 patients receiving peripheral nerve block (42%) and 12 receiving spinal anaesthesia (30%) by-passed the post-anaesthesia care unit after surgery as compared with only two general anaesthesia patients (5%; p=0.01). Discharge from the post-anaesthesia care unit was more rapid after peripheral block; however, stay in the Day Surgery Unit was shorter after general anaesthesia than peripheral or spinal blocks (p=0.026). Urinary retention was reported in three spinal anaesthesia patients only (8%; p=0.03). Regional anaesthesia techniques reduce the rate of admission and the duration of stay in the post-anaesthesia care unit as compared with general anaesthesia. Peripheral rather than spinal nerve blocks should be preferred to minimise the risk of urinary retention

Background and purpose of the study. Effective communication between healthcare professionals and patients is key to a successful consultation and is reported to affect both adherence to treatment and outcome. Despite this evidence, research on how best to open consultations is limited and the optimal way, unknown. This study seeks the opinions of physiotherapists on how to open a clinical encounter in an adult musculoskeletal outpatient setting – a topic which has relevance to all clinicians aiming to build rapport with their patients. Methods. Forty clinical encounters between physiotherapists in a primary care setting and patients with back pain were observed and audio-recorded. The clinicians' key questions inviting the patient to discuss their back pain were identified, together with a content analysis of the topics discussed prior to the conversation about their back pain. In 2012, a national survey was undertaken, approaching 34,922 physiotherapists from 3 networks on the interactive website hosted by the professional body, the Chartered Society of Physiotherapy asking participants to rank the data from clinical practice, to determine the preferred way to open a clinical encounter. Results. Form the 40 recorded consultations eleven opening questions were identified. In these encounters fourteen other topics were discussed before the key opening question about back pain. In the national survey, the top 5 openings were identified. Conclusion. Knowing how clinicians and patients communicate, and specifically, how clinical encounters are opened, is important for teaching and professional development to assist clinicians in optimising their non-specific treatment effects. No Conflict of interest. No funding obtained. This abstract has not been previously published in whole or substantial part nor has it been presented previously at a national meeting

Purpose: To determine if oral midazolam reduces the anxiety of children undergoing removal of percutaneous Kirschner wires (K-wires) from the distal humerus in the Orthopaedic Outpatient Department. Methods: This was a prospective double blind, randomised controlled trial. 46 children aged between 3 and 12 years who had supracondylar fractures of the distal humerus internally fixed with K-wires were randomised into 2 groups. 0.2mg/kg oral midazolam (active group) or the same volume of an oral placebo (control group) was administered 30 minutes prior to removal of K-wires. Venham Situational Anxiety Score was performed before and immediately after removal of K-wires. University College London Hospital sedation score was recorded every 20 minutes. Results: 42 children with an average age of 7.1 years (range 3.6–12.3 years) had complete documentation for analysis. The two groups had similar demographics. All wires were removed in the clinic with or without midazolam. There was no significant difference in anxiety scores between the groups either before or after wire removal. The change in scores was not significantly different between the 2 groups. However, 45% of children in the active group had reduced anxiety levels in the active group compared to 18% of children given placebo but this difference was not significant (p=0.102). No child was excessively sedated but one in the active group became agitated and restless. Conclusions: The anxiety scores before and after wire removal in the active group were not significantly different from the placebo group scores. We do not recommend the routine administration of midazolam (0.2 mg/kg) to all children requiring k-wire removal in the outpatient department

Purpose. To prospectively assess the safety, efficacy and patient satisfaction of a standardised perioperative anesthetic and pain management protocol for outpatient Total Ankle Arthroplasty. Method. Starting February 2008 we chose to enrol 50 consecutive patients undergoing Total Ankle Arthroplasty in this study. All patients were assesed and treated by a single Anesthesiologist and Orthopedic surgeon. All patients received preoperative dosing of Celebrex, Oxycontin and Gabapentin. Anesthesia consisted of a popliteal regional block and a spinal anesthetic. Patients were discharged home when they were stable with adequate pain control and able to ambulate with crutches or a walker. All patients were contacted by telephone by the treating Anesthesiologist to assess for pain control, complications and satisfaction on the night of surgery and for the next two days. Patients were also given contact numbers to call the Anesthesiologist for any concerns outside of these times. All patients were assessed by the treating Orthopedic surgeon at two and six weeks post surgery with data collected regarding wound complications, infection, deep venous thrombosis and overall patient satisfaction. Results. All 50 consecutive patients underwent successful regional and spinal anesthesia. All patients were stable for discharge the same day as the surgery. One patient experienced nausea in the Recovery Room but was treated with standard antinausea medication and was subsequently discharged home. Forty three patients reported pain scores of less than 3/10 throughout the post operative phase. Four patients experienced mild pain (3/10) and three patients reported moderate pain level (5/10). All seven patients were treated with analgesic dose titration and/or education regarding the need to take all medications prescribed at the proper time intervals. None of the patients required further intervention or readmission for either pain control or complications of anesthesia. All patients were reviewed by the treating Orthopedic surgeon at two and six weeks postoperatively. There were no early surgical complications and all wounds healed without difficulty or sepsis. All patients admitted to being satisfied or highly satisfied with their surgical experience and post operative pain management. Conclusion. Total Ankle Arthroplasty can be performed safely on an outpatient basis with excellent pain control and a high level of patient satisfaction. We now utilize regional anesthesia and the multimodal pre- and post-operative pain management protocol described for all complex foot and ankle surgery. This has allowed for greater throughput of operative cases and significant cost savings for our Institution

We do not recommend the routine administration of midazolam (0.2 mg/kg) to all children requiring k-wire removal in the outpatient department

Aim. In an earlier study we identified severe Vitamin D deficiency as a problem in institutionalised children with cerebral palsy (CP), which resulted in rickets and a high incidence of fractures. The purpose of this study was to establish whether a cohort of non-ambulatory children with CP, living at home, presented with Vitamin D deficiency. Method. The participants were a consecutive sample (N=100) of non-ambulatory children with CP attending a CP outpatient clinic. Their ages ranged from 2 to 15 years (mean 5.8, SD 3.3 years). There were 57 males and 43 females. Nineteen were on Level IV of the Gross Motor Function Classification System (GMFCS), and 81 were on Level V. 66% were on anticonvulsant therapy (ACT). Basic demographic data was collected, and measurements included blood sample analysis and wrist radiographs. There was radiographic evidence of osteopenia and delayed ossification of the carpal bones. Results. Three participants had Vitamin D deficiency rickets confirmed by wrist changes and serology. There was a significantly higher level of Alkaline Phosphatase (p=0.04) in children on ACT than in those who did not receive ACT. Preliminary results show that one third of the children had Vitamin D deficiency. Conclusion. Non ambulatory children with CP are at risk of developing rickets. We recommend regular exposure to sunlight or Vitamin D supplementation as preventative measures. NO DISCLOSURES

Percutaneous A1 pulley release is being increasingly used as an alternative to open surgical release and injection of local steroids for the treatment of the trigger digit. We treated 43 patients, average age 57 years (range12-78). All trigger digits were grade III-IV (Quinnell classification). A mean duration of pre-operative symptoms was 7.3 months (range 2-13 months). A percutaneous release was performed with a 19-gauge hypodermic needle under local anaesthesia in the outpatient setting. All patients were evaluated with respect to clinical resolution of symptoms and general satisfaction. We report a 97% successful release and only one case of incomplete release. A result in terms of abolishing triggering was immediate and patient acceptance was excellent. By two weeks, all the patients had no pain at the operative site. After a mean follow-up of 30.2 months (range12-50), there had been no recurrences. There were no digital nerve injuries, flexor tendon injuries, and infections. The percutaneous release is a safe and effective technique, which provides significant cost savings. The time from onset of symptoms and grading prognostically is significant and affects the treatment outcome. We recommend the percutaneous technique for typical cases of trigger finger with a palpable nodule and reproducible mechanical triggering. This technique can be the treatment of choice for the established trigger finger (grade III and IV) with symptoms of more than few months' duration. The open technique is reserved for complicated cases such as florid tenosynovitis, locked digit, failed percutaneous release or those involving the thumb

Abstract

The aim is to describe the safety and efficacy of TAL in out-patient clinics when managing diabetic forefoot ulcers.

In January 2005, NICE published their guidelines on secondary prevention of osteoporotic fractures. This audit aims to assess our compliance with these in the outpatient setting. The records of all new patients attending fracture clinic in a large teaching hospital, over a one month period, were reviewed. All patients who required screening or treatment for osteoporosis (females greater than 50 years old sustaining a fragility fracture) were reviewed at one year to assess compliance with the guidelines. Of the 454 patients reviewed, 90 females over the age of 50 (19%) were identified. These were further subdivided into females between the age of 50 to 75 years (Group A, n=62) and those over 75 (Group B, n=28). The inclusion criteria was presence of a fragility fracture (Group A, n=30 and Group B, n=15). Group A was investigated with DEXA scans in only 26.7% (n=8). Of these, only six were managed as per NICE guidelines and compliant at one-year. Seven patients in Group B were subsequently treated with medical therapies, but only three were managed as per NICE guidelines and compliant. Therefore of the 45 patients included in the audit, only nine were managed appropriately at one-year (20%). One patient suffered a further fracture – who had been fully compliant with treatment. NICE guidelines have been introduced to help the nation’s health using evidence based criteria. There has been no specific extra funding to enable the setting up of additional pathways and investigations for the targeted population. Even in a busy department where systems were implemented to follow the guidelines, the overall compliance with the pathway is less than a quarter. When new guidance is produced for healthcare, there should be advice, support and funding for their implementation

Introduction. Post-operative gait abnormalities are recognized following total hip arthroplasty (THA). Despite global improvement in functional outcome, gait abnormality persists for a decade or more. In this study 3-dimensional gait analysis (3DGA) was performed using a portable system with Inertial Measurement Units (IMUs) to quantify this abnormality. Methods. The gait of 55 patients with monarthrodial hip arthrosis was measured pre-operatively and at one year post-surgery. Patients with medical co-morbidity or other conditions affecting their gait were excluded. Six IMUs were aligned at the level of the anterior superior iliac spines, mid-thigh and mid-leg. Data was analysed using proprietary software. Each patient underwent a conventional THA using a posterolateral approach. 92 healthy individuals were assessed for comparison. Results. Pre-operative movement in the sagittal plane of the ipsilateral hip (mean range 20.4) and the contra-lateral non-diseased hip (35.3 degrees) was reduced compared to the control group (40.5 degrees), (P<0.001). The pre-operative movement of both knees was reduced compared with normal (P<0.001). Pelvic movement on the ipsilateral side was increased. After one year ipsilateral hip movement significantly improved (Mean range 28.9 deg SD 6.6) but did not reach normal values (P<0.001). Movement measured in the contralateral hip was further reduced with a mean difference of −5.25 degrees (95% CI −8.06 to −2.43). Knee movement on both sides increased but not to normal values (p<0.001). There was increased coronal movement bilaterally at the thigh and calf one year after surgery. Discussion and Conclusion. Gait after routine THA does not return to normal. Unilateral hip pathology causes bilateral gait abnormality affecting the entire kinematic chain. This portable technology allows practical assessment of gait in the outpatient setting and will enable identification of key aspects of gait abnormality to target during rehabilitation following THA

Summary: A large number of review appointments in elective clinics are to discuss results. In well-informed patients, investigations and treatment plans can be discussed by telephone, avoiding the need for a face-to-face consultation. This saves resources, assists in achieving treatment pathway targets, and is financially viable and acceptable to patients. Background: An audit of the Plymouth foot & ankle service highlighted a long patient wait to discuss the outcome of investigations and plan treatment. Not only is this unacceptable for patients, it adversely affects the flow of the RTT pathways. Derriford Hospital has a wide catchment area and the foot & ankle service has a military catchment area from Cornwall to Buckinghamshire. Method: During the initial outpatient consultation, if the clinician feels that the patient is suitable, an arrangement is made to discuss the results of investigations and subsequent treatment plan by telephone. The treatment options are re-iterated in a summary letter of the consultation to the patient. Conclusion: The preliminary 3 month results are presented and as a concept the clinic has been successful, being acceptable to all patients involved and reducing the requirement to provide additional clinics

Ilizarov frame removal often occurs in the outpatient setting, and previous data has shown it can be a painful experience. Frames with a total of four or more olive wires or half-pins in combination yielded increased pain scores at frame removal. Sublingual fentanyl provides rapid onset, short acting analgesia for painful procedures such as dressing changes in burns patients. We hypothesised that administration of sublingual fentanyl, prior to frame removal would improve patients' pain scores. Twenty-one patients were given 100 mcg sublingual fentanyl prior to frame removal. Their pain scores were documented on an 11-point (0–10) numeric visual scale before, immediately after, 15 and 30 minutes after frame removal, and the following day. The same nurse specialist removed all the frames. Nitrous oxide was available for patients if they needed further analgesia. The majority of frames were removed from tibia. The average patient age was 40.8 years. Each frame had a median of 9 wires (range 2–17), and 4 olives (2–8). Eight frames had half pins (range 1–4, median 2). Fourteen patients used nitrous oxide in addition to fentanyl. Overall, the average pain score was 3.1. This peaked at 7.5 immediately after frame removal, but 15 minutes following removal the average was 2.5. Patients who had supplementary nitrous oxide had higher pain scores throughout (though not beforehand), although these differences were not statistically significant. Four patients (19%) reported adverse effects following administration, but none required medical intervention. Patients' pain scores averaged 2.52 within 15 minutes of removal, compared with 5.25 from our previous review. This suggests that fentanyl may be beneficial in frame removal, but our sample size was small, and more research is needed in this area

Rising health costs have seen increased emphasis on cost containment. Outpatient follow-up after total joint arthroplasty is one such accumulating cost. Enthusiastic recent media interest in failing implants and unacceptable waiting lists adds further interest to the area. We wished to determine the current post-operative follow-up practices and views of New Zealand Orthopaedic Surgeons. A postal survey was sent to all New Zealand Orthopaedic Surgeons. The response rate was 83% (131/158). There was wide variation in routine practice and beliefs. For cemented THJRs, 13% of surgeons routinely saw their patients for less than one year, 38% followed their patients for less than five years and 53% continued to see patients indefinitely. Follow-up for uncemented/hybrid prostheses was higher: 8% for < one year, 29% for < 5 years and 59% indefinitely. A system of periodically re-calling patients for x-rays without necessarily seeing them is used by 20% of surgeons. The most frequent reasons given for follow-up were the detection of osteolysis, wear, loosening and patient symptoms. Similar figures for total and uni-compartmental knee replacements were reported. Almost a third of surgeons reported that they were unable to follow-up their patients as they would like to because of resource limitations within the public health sector. 44% believed that future changes in medico-legal expectations will necessitate longer follow-up of patients. This survey demonstrates wide variation in practice. Higher follow-up rates for un-cemented/hybrid prostheses may reflect uncertainty about the long-term results. There is concern amongst surgeons that their ability to follow-up patients within the public health-care sector is constrained by cost. Periodic questionnaire and x-ray assessment was suggested by many as a possible alternative for long-term follow-up of selected patients. Few surgeons are however presently using such a system. We propose a standard of care

Introduction:. UKA allows replacement of a single compartment in patients who have isolated osteoarthritis. However, limited visualization of the surgical site and lack of patient-specific planning provides challenges in ensuring accurate alignment and placement of the prostheses. Robotic technology provides three-dimensional pre-op planning, intra-operative ligament balancing and haptic guidance of bone preparation to mitigate the risks inherent with current manual instrumentation. The aim of this study is to examine the clinical outcomes of a large series of robot-assisted UKA patients. Methods:. The results of 500 consecutive medial UKAs performed by a single surgeon with the use of a metal backed, cemented prosthesis installed with haptic robotic guidance. The average age of the patients at the time of the index procedure was 71.1 years (range was 40 to 93 years). The average height was 68 inches (range 58″–77″) and the average weight was 192.0 pounds (range 104–339 pounds). There were 309 males and 191 females. The follow-up ranges from 2 weeks to 44 months. Results:. Surgical Technique: The technique evolved from a one night stay with a tourniquet and a retinacular “T'd” arthrotomy, to a same day surgical procedure with a 2.5–3 inch straight medial arthrotomy that is muscle sparing and tourniquet free allowing all patients to go home the same day with only 2–3 weeks of formal physical therapy post op, less pain medication and a quicker return to their preoperative range of motion. Clinical Outcomes: All patients increased their ROM by 3–6 months postop. The return to preoperative ROM was seen by 6 weeks with an increased ROM of 5–10 degrees by 1 year. 6 out of 500 patients were converted to a TKA (1.2%). Two for deep infection (one had severe venous stasis disease preop), Three for medial pain despite stable, well aligned implants, and one who developed pain at around 6 weeks that had a large scar band that formed across the top of the tibial poly causing pain with weight bearing. Conclusion:. This evolved surgical technique along with the use of the sophisticated, patient-specific preoperative and intraoperative planning software combined with haptically guided bone resection allowed most patients, regardless of age, to have their procedure performed as an outpatient. This new technique can provide significant savings to the healthcare system in terms of costs of hospital days, costs of rehabilitation, costs in pain medication and quality of life in the acute post operative period with no increased risk of failure, loosening, malalignment, DVT, PE, infection, return to the OR, readmissions, or manipulation

The aim of the study was to assess the validity of the new device [BREVIO] [AEND] [Level 2 evidence] in diagnosing carpal tunnel syndrome in the outpatient setting when used by personnel not trained previously in neurophysiologic methods. We prospectively compared the results from a portable handheld automated electroneurodiagnostic devices (AEND) the BREVIO with those from conventional nerve conduction studies. We calculated specificity and sensitivity. We also studied the limits of agreement and correlation between measured latencies. Patient satisfaction with new device was recorded. Twenty-seven participants (42 hands) were tested. The average age was 56.43 years (38-79). There were 16 females and 11 males. The sensitivity and specificity of the BREVIO as compared to conventional methods were 80% and 75% using distal motor latencies; using distal sensory latencies the sensitivity and specificity were 90% and 60% respectively. The limits of agreement between the sensory and motor latencies using Bland Altman plots were good. Similarly there was good correlation between values measured with the Pearson's correlation coefficient. The position of the baseline cursor was questionable in 19 hands. Repositioning the cursor reduced the number of false positive results which would increase the specificity of the device. The average pain score, VAS on a scale of 1-10, with the BREVIO was 1.69 (1-4) and 3.11(1-5) with conventional testing. The average satisfaction rating on a scale of 1-5 was 1.39 with the BREVIO and 2.73 with the conventional nerve conduction testing. The BREVIO is an interesting device. We recommend its use by untrained persons only under the supervision of someone trained in neurophysiology who is aware of potential pitfalls

This study aims to determine the incidence of surgical site infection leading to reoperation for sepsis following minor hand procedures performed outside the main operating room using field sterility in the South African setting.

The investigators retrospectively reviewed the records of 485 patients who had WALANT-assisted minor hand surgery outside a main operating theatre, a field sterility setting between March 2019 and April 2023. The primary outcome was the presence or absence of deep surgical site infection that required reoperation within four weeks. Cases included where elective WALANT minor hand procedures, a minimum age of 18 with complete clinical records.

The patients were mostly female (54.8%), with a mean age of 56.35 years. The majority of cases were trigger finger and carpal tunnel release. An overall 485 cases were reviewed, the deep surgical site infection rate resulting in reoperation within 4 weeks post-operatively was 1.24% ((95% Confidence Interval (CI) 0.0034 to 0.0237); p = 0.009).

Minor hand procedures performed under field sterility using WALANT have a low surgical site infection rate. The current study's infection rates are comparable to international surgical site infection rates for similar surgeries performed in main operating rooms using standard sterilisation procedures. Field sterility is a safe and acceptable clinical practice that may improve work efficiency in public sector.

The entirety of the patient experience after contemporary total knee and total hip replacements in 2017 is markedly different from that encountered by patients just a decade ago. Ten years ago most patients were treated in a traditional sick-patient model of care and because they were assumed to require substantial hospital intervention, many cumbersome and costly interventions (e.g. indwelling urinary catheters, patient-controlled-analgesic pumps, autologous blood transfusion, continuous passive motion machines) were a routine part of the early post-operative experience. Today the paradigm has shifted to a well-patient model with a working assumption that once a patient has been medically optimised for surgery then the intervention itself, hip or knee replacement, will not typically create a sick-patient. Instead it is expected that most patients can be treated safely and more effectively with less intensive hospital intervention. While as orthopaedic surgeons we are enamored with the latest surgical techniques or interesting technologies most busy surgeons recognise that advances in peri-operative pain management, blood management, and early-mobilization therapy protocols account for the greatest share of improvements in patient experience over the past decade.

One can think pragmatically to get ahead and stay ahead of 3 predictable physiologic disturbances that adversely impact rapid recovery after knee and hip replacement: fluid/blood loss; pain; and nausea. The modern orthopaedic surgeon and his/her care team needs a simple strategy to pro-actively, not reflexively, manage each of those 3 predictable impediments to early recovery. Those surgical teams that routinely get ahead and stay ahead in each of those areas will routinely witness faster recovery, lower costs and greater patient satisfaction and that is clearly a win for patient and surgeon alike.

Effective pain management improves patient satisfaction, decreases hospital stay, and facilitates discharge to home. Today's emphasis is on a multi-modal strategy that minimises the use of opioids. Most protocols use pre-operative medications including an NSAID, acetaminophen, an oral opioid and some include gabapentin. Regional anesthesia is typically preferred over general. Both peripheral nerve blocks and periarticular local anesthetic cocktail injections have proved as effective adjuncts in decreasing early post-operative pain. Post-operative oral medications delivered on a schedule, not just as needed, often include acetaminophen, an NSAID and some include gabapentin. Oral and parenteral opioids are reserved for breakthrough pain.

Two hundred and eighty-three patients with tuberculosis of the thoracic and/or lumbar spine have been followed for 10 years from the start of treatment. All patients received PAS plus isoniazid daily for 18 months, either with streptomycin for the first three months (SPH) or no streptomycin (PH), by random allocation. There was also a second random allocation for all patients: in Masan to inpatient rest in bed (IP) for six months followed by outpatient treatment or to ambulatory outpatient treatment from the start (OP), and in Pusan to outpatient treatment with a plaster-of-Paris jacket (J) for nine months or to ambulatory treatment without any support (No J). A favourable status was achieved on their allocated regimen by 88% of patients at 10 years. Some of the remaining patients also attained a favourable status after additional chemotherapy and/or operation, and if these are included the proportion achieving such a status increases to 96%. There were five patients whose deaths were attributed to their spinal disease. A sinus or clinically evident abscess was present on at least one occasion in the 10-year period in 42% of the patients. Residual sinuses persisted at 10 years in two patients, at death at seven years in a third and at default in the seventh year in a fourth. Thirty-five patients had paraparesis at some time during the 10-year period, including two who died with paraplegia before five years. Complete resolution occurred in 26 patients (in six after additional chemotherapy and/or surgery). At 10 years two patients had severe paraplegia and one a moderate paraparesis.(ABSTRACT TRUNCATED AT 250 WORDS)

An audit was carried out to assess the management of patients with fragility fractures in fracture clinic and primary care. NICE guidelines advise these patients require treatment for osteoporosis if 75 years or older, and a DEXA scan if below this age.

Distal radius and proximal humeral fractures were identified in a retrospective review of letters from 10 fracture clinics. Current medication of all patients ≥ 75 years was accessed and DEXA scan requests identified for patients < 75 years.

There were 69 fragility fractures: 53 distal radius and 16 proximal humerus. 4 letters (6%) mentioned fragility fracture and advised treatment and 3 (3%) correctly advised a DEXA scan. Only 3 of 25 (10%) patients ≥ 75yrs not previously on osteoporosis medication had treatment started by their GPs. 3 of a possible 29 (10%) patients < 75 years were referred for a DEXA scan.

A text box highlighting fragility fractures and NICE guidelines was added to all clinic letters for patient ≥ 50 years old. Re-audits showed an improvement in management of these fractures, with 45% of patients ≥ 75 years being started on treatment and 39% of patients < 75 years being referred for a DEXA scan.

Aims

Increasing demand for total hip and knee arthroplasty (THA/TKA) and associated follow-up has placed huge demands on orthopaedic services. Feasible follow-up mechanisms are therefore essential.

The Ponseti and French taping methods have reduced the incidence of major surgery in congenital idiopathic clubfoot but incur a significant burden of care, including heel-cord tenotomy. We developed a non-operative regime to reduce treatment intensity without affecting outcome. We treated 402 primary idiopathic clubfeet in patients aged < three months who presented between September 1991 and August 2008. Their Harrold and Walker grades were 6.0% mild, 25.6% moderate and 68.4% severe. All underwent a dynamic outpatient taping regime over five weeks based on Ponseti manipulation, modified Jones strapping and home exercises. Feet with residual equinus (six feet, 1.5%) or relapse within six months (83 feet, 20.9%) underwent one to three additional tapings. Correction was maintained with below-knee splints, exercises and shoes. The clinical outcome at three years of age (385 feet, 95.8% follow-up) showed that taping alone corrected 357 feet (92.7%, ‘good’). Late relapses or failure of taping required limited posterior release in 20 feet (5.2%, ‘fair’) or posteromedial release in eight feet (2.1%, ‘poor’). The long-term (> 10 years) outcomes in 44 feet (23.8% follow-up) were assessed by the Laaveg–Ponseti method as excellent (23 feet, 52.3%), good (17 feet, 38.6%), fair (three feet, 6.8%) or poor (one foot, 2.3%). These compare favourably with published long-term results of the Ponseti or French methods. This dynamic taping regime is a simple non-operative method that delivers improved medium-term and promising long-term results.

Weber A fractures are a sub-group of ankle fractures parallel or distal to the joint line, below the level of the syndesmosis. Most stable Weber A fractures are managed conservatively with no significant difference in outcome vs. surgical intervention.^1,2In an effort to ensure staff time was being used as efficiently as possible, a consultant-led virtual fracture clinic (VFC) was introduced to manage Weber A fractures. Patients not requiring immediate surgery were reviewed remotely and, wherever possible, were ‘virtually discharged’ to a nurse-led telephone line. Those with diagnostic uncertainty, unusual features or delayed recovery received a face to face review from a nurse or surgeon.

To examine how patients were allocated under this protocol, along with overall patient satisfaction and functional outcome.

An audit of satisfaction and outcome was performed of all patients who presented with a Weber A fracture to the ED between October 2011 and October 2012. The minimum follow-up period was two years. A satisfaction and patient reported outcome (5-level-likert-scale, EQ-5D, MOXFQ) measure was conducted via telephone.^3,4After exclusions, 79 patients were left, of which 63 were successfully contacted (80%).

Of the 79 patients included, 33 (42%) required early face-to-face review while 46 (58%) were discharged with advice following discussion at the VFC. Of the 63 successfully contacted, receipt of the information leaflet was recalled by 61 (97%) and 54 (86%) were satisfied with the information they had received. There was no difference in patient satisfaction regarding recovery (p=0.079) or treatment information (p=0.236) provided between avulsion and transverse fractures or in functional outcome according to MOXFQ (p=0.626) or EQ-Vas (p=0.915) scores.

Patient satisfaction can remain high without face-to-face consultations following injury. This was demonstrated by the high satisfaction with recovery (83%) and with information provided (86%) and is consistent with current published literature and similar to what would have been achieved with traditional fracture clinic review.⁵The new protocol reduces unnecessary hospital attendances for patients and reduces the burden of unnecessary review in orthopaedic departments. Only 15% of patients required review at a traditional fracture clinic and 27% at a nurse-led clinic, freeing resources for more complex cases.

Introduction

There are approximately 1.2 million patients using orthotics in the UK costing the NHS in excess of £100 million per annum. Despite this, there is little data available to determine efficacy and patient compliance. There have been a few reports on patient satisfaction, which indicate that between 13-50% of patients are dissatisfied with their orthotics. Our aim was to evaluate patient reported satisfaction with orthotics prescribed and to investigate the reasons behind patient dissatisfaction.

Aims: To validate a set of simple clinical tests, these could then be used to establish an objective assessment of an individualñs ability to perform an emergency stop safely in orthopaedic clinics. Methods: This prospective ethically approved study involved assessment of emergency breaking reaction times of Right knee arthroscopy patients using a computer linked car simulator designed by Transport Research Laboratory (TRL). The ability to perform an emergency stop was assessed as the time taken to achieve a brake pressure of 200N after a visual stimulus. Each patient was tested preoperatively, 1 day and 1 week after arthroscopy. In addition three speciþcally designed clinical tests were performed, i.e, a) Knee ßexion during single leg stance; b) Active plantar ßexion against the weight of the whole body during single leg stance c) straight leg raise for 10 seconds. Results: In total 31 patients completed the study. The average reaction time preoperatively was 750ms; Correlation between driving reaction times and the results of clinical tests was performed. Statistical analysis revealed sensitivity up to 96%, speciþcity up to 71% and positive predictive value up to 92% for the clinical tests. Conclusions: Ç Doctor when I can drive? È is a common question faced by all orthopaedic surgeons in the clinics. As driving simulators are not available in the clinics it is appropriate for patients to be assessed with these simple clinical tests, to decide the actual timing of return to driving. A similar study involving joint replacement patients is underway.

To assess the safety of day case lumbar decompressive surgery

Introduction: Mismatch between patient load and out-patient clinic resources in South Australian public sector has resulted in a long waiting list for initial appointment of new patients with shoulder complaints. There is no validated triage tool to help prioritize the patient referrals appropriately, to avoid inappropriate delays.

Methods: We devised a self evaluation questionnaire to appropriately triage new referrals with shoulder complaints. Ethics committee approval was obtained. Forty eight new referrals to shoulder clinic filled in this questionnaire and the self evaluation part of American Shoulder and Elbow Society form. The patients were assessed in chronological order by two surgeons. Both were blinded to the GP referral and questionnaire findings at the time of patient assessment. GP referrals and the questionnaires were subsequently assessed and triaged. These findings were compared to assessment in the clinic.

Results: Whilst the questionnaire provided significantly more information when compared to GP referrals, both were inadequate on their own as reliable triage tool. However in combination, majority of the patients could be triaged appropriately. Based on the presumptive diagnosis, basic investigations and therapy can be correctly instituted whilst awaiting formal orthopaedic review. None of the patients would have been allocated a lower priority than appropriate. The self evaluation part of ASES form on its own was not a satisfactory tool for triaging.

Discussion: The proposed questionnaire and initial referral letter can be used for safe triaging and ensuring most basic relevant clinical workup is done prior to presentation. Further refinement of the questionnaire and additional studies are required to fully define its role in routine public hospital use.

Introduction & aims: Quadriceps muscle wasting is common in patients with osteoarthritis (OA) of the hip and knee. Previous studies,using ultrasound and performing biopsies, have demonstrated quadriceps muscle fibre atrophy. Thigh girth measurements are quoted in textbooks as a means of quantitatively assessing muscle bulk. This study has looked at these measurements in patients with hip and knee OA to see if these measurements are useful.

Method: 87 patients (mean age 62, range 36–87) with a diagnosis of OA were seen in the pre-assessment clinic. 47 were awaiting total hip replacement (THR) and 40 were awaiting total knee replacement (TKR).All were awaiting primary arthroplasty and had not had previous joint surgery. Thigh girth measurements were taken at 2 points corresponding with one-third and two-thirds of the length between the anterior superior iliac spine and the tibial tuberosity. These measurements were taken for both thighs. The observed differences were analysed with normal probability plots and paired Student’s t-tests.

Results: No significant difference in thigh girth could be detected in patients awaiting total knee replacement. Girth was significantly reduced in the thigh on the side of planned THR. This difference was apparent when measured both proximally and distally.

Conclusion: Measurements of thigh girth were not useful indicators of quadriceps wasting in patients awaiting TKR. Patients awaiting THR should have thigh girth measured, those with reduced thigh girth on the side of planned arthroplasty may have quadriceps atrophy and can then be referred for physiotherapy prior to surgery.

Most hip replacements are performed in an in-patient setting; however, there has been a shift in recent years in Canada towards doing more on an outpatient basis. In 2021–2022, 15.6% of hip replacements were performed as day surgeries compared to 0.7% in 2018–2019. This analysis will assess patient reported outcome measures of patients who had inpatient versus outpatient hip replacement surgery between 2018 and 2021. We analysed a retrospective sample of 4917 adult patients who had an elective primary unilateral hip replacement. Preoperative and three-month postoperative PROMs were completed - the Oxford Hip Score, EQD5L and patient satisfaction with the outcome were recorded. Patients who had an outpatient procedure were matched 1:1 with patients who are admitted to hospital for surgery based on age, sex and pre-COVID versus the COVID (March 15, 2020 as the start). Preoperative PROMs and Charlson Comorbidity Index were collected. T-tests and chi-square tests were used to assess the differences. The inpatient group on average was older, female and had a lower preoperative PROMs score and more comorbidities than the outpatient group. With cohort matching the sample consisted of 1244 patients. The inpatient and outpatient groups have similar Oxford scores, postoperative EQ-5D-5L scores and the proportion satisfied with their surgical results. The Oxford postoperative score was slightly higher in the outpatient group compared to the inpatient group; however, this is not clinically significant. We observed that outpatient protocols have no difference in patient satisfaction, self-reported functional outcomes and self-reported health-related quality of life three months after a hip replacement. Day surgery protocols represented potential solution to the challenges caused by the expected increase in demand for hip replacements. Our results demonstrated that patients do well clinically with day surgery procedures and there does not appear to be any detrimental effect on PROMs

Abstract. Introduction. Transforming outpatient services is a key commitment set out in the NHS Long Term Plan, with particular emphasis on digital solutions to reduce outpatient follow-up (FU) by 25%. This study looks at the potential for removing knee arthroscopy FU by providing a bespoke multimedia report for each individual patient, generated using the Synergy™ Surgeon App (Arthrex). Methodology. Single District Hospital using a 3 Phase study. Phase 1 – Assessment of cost and environmental impact of outpatient follow up appointments. Phase 2 – Bench marking of existing pathways and patient experience. Phase 3 – Qualitative assessment of multimedia report feedback of 30 patients. Results. Phase 1 – Impact per year for Trust in released clinician time 135hrs. Cost avoidance £40-£60k. Reduction of the carbon footprint from reduced FU of 3132 KgCo2e2. Phase 2 – Deep dive on 2019 n. 353 procedures. 1206 outpatient appointments required. Average 1.2 post-operative appointments. Phase 3 – 87% of patients who received the e-op report needed no further FU. This compares to only 25% using a traditional post op discussion after surgery. 94% of patients felt the report aided their recovery. Conclusions. Reducing patient FU appointments is crucial to the future of the NHS. Achieving this whilst simultaneously improving the quality of patient communication is achievable as this study has demonstrated. The potential scalability of this project to be applied other arthroscopic procedures is enormous. The study has demonstrated patients are comfortable with modern technology and feel it enhances their understanding whilst decreasing the need for routine post-op FU

Orthopaedic surgeons prescribe more opioids than any other surgical speciality. Opioids remain the analgesic of choice following arthroscopic knee and shoulder surgery. There is growing evidence that opioid-sparing protocols may reduce postoperative opioid consumption while adequately addressing patients’ pain. However, there are a lack of prospective, comparative trials evaluating their effectiveness. The objective of the current randomized controlled trial (RCT) was to evaluate the efficacy of a multi-modal, opioid-sparing approach to postoperative pain management in patients undergoing arthroscopic shoulder and knee surgery. The NO PAin trial is a pragmatic, definitive RCT (NCT04566250) enrolling 200 adult patients undergoing outpatient shoulder or knee arthroscopy. Patients are randomly assigned in a 1:1 ratio to an opioid-sparing group or standard of care. The opioid-sparing group receives a three-pronged prescription package consisting of 1) a non-opioid prescription: naproxen, acetaminophen and pantoprazole, 2) a limited opioid “rescue prescription” of hydromorphone, and 3) a patient education infographic. The control group is the current standard of care as per the treating surgeon, which consists of an opioid analgesic. The primary outcome of interest is oral morphine equivalent (OME) consumption up to 6 weeks postoperatively. The secondary outcomes are postoperative pain scores, patient satisfaction, quantity of OMEs prescribed and number of opioid refills. Patients are followed at both 2 and 6 weeks postoperatively. Data analysts and outcome assessors are blinded to the treatment groups. As of December 1, 2021 we have enrolled 166 patients, reaching 83% of target enrolment. Based on the current recruitment rate, we anticipate that enrolment will be completed by the end of January 2022 with final follow-up and study close out completed by March of 2022. The final results will be released at the Canadian Orthopaedic Association Meeting in June 2022 and be presented as follows. The mean difference in OME consumption was XX (95%CI: YY-YY, p=X). The mean difference in OMEs prescribed was XX (95%CI: YY-YY, p=X). The mean difference in Visual Analogue Pain Scores (VAS) and patient satisfaction are XX (95%CI: YY-YY, p=X). The absolute difference in opioid refills was XX (95%CI: YY-YY, p=X). The results of the current study will demonstrate whether an opioid sparing approach to postoperative outpatient pain management is effective at reducing opioid consumption while adequately addressing postoperative pain in patients undergoing outpatient shoulder and knee arthroscopy. This study is novel in the field of arthroscopic surgery, and its results will help to guide appropriate postoperative analgesic management following these widely performed procedures

Aim. Bone and joint infection requires antimicrobial treatment for 6 to 12 weeks. When patients are well prepared and instructed regarding their therapy, they are more likely to have less side effects and improved compliance. Although side effects are common, this coaching is often not routinely performed when oral treatment is given. We developed a monitoring and guidance program for our outpatients who are on long term antimicrobial therapy, in which we can early signal side effects and treatment failure and coach the patients in their journey of infection treatment. Method. In our tertiary referral centre for orthopaedic infections, we started the outpatient monitoring of antimicrobial treatment (OMAT)- team for patients who will receive antimicrobial therapy for >2 weeks. Before discharge, our trained nurse gives instruction to the patient. Within 3 days after hospital discharge the patient is contacted by phone to, if necessary, clarify ambiguities in monitoring set up. During this contact, the nurse checks for side effects, addresses logistic problems regarding laboratory monitoring or future appointments and coaches patients for other questions. The patient is instructed how to recognize and who to contact in case of red flags and problems possibly related to the treatment. This is repeated after every laboratory check-up. Supervision is performed by an infectious disease specialist in close collaboration with the patient's surgeon. Results. The OMAT-team started in October 2020 and consists of 3 trained nurses and 3 ID specialist. In one year, 453 patients were proactively monitored for a mean of 11 weeks. Routinely, laboratory measurements were performed 1 week after the start of therapy and every 3–4 weeks thereafter, which resulted in 2711 contacts per year. In total, 64% of the patients reported side effects and 13% needed one or more extra laboratory measurement. This led to 40 additional outpatient consultations by the ID specialist because of complications of treatment and a switch of the antimicrobial agent in 31% of the patients. Conclusions. OMAT seems to improve the early signalling of complications regarding treatment, which is likely to improve compliance. The OMAT-team serves as a easy to access team to discuss any problem regarding antimicrobial therapy. Being proactive, the OMAT-team intervenes in an early stage of problems regarding side effects, logistics of the treatment and possible treatment failure. Future analysis of our data will show to what extend this will lead to prevention of re-hospitalization and improvement of success rate

The mean difference in OMEs prescribed was XX (95%CI: YY-YY, p=X). The mean difference in Visual Analogue Pain Scores (VAS) and patient satisfaction are XX (95%CI: YY-YY, p=X). The absolute difference in opioid refills was XX (95%CI: YY-YY, p=X). The results of the current study will demonstrate whether an opioid sparing approach to postoperative outpatient pain management is effective at reducing opioid consumption while adequately addressing postoperative pain in patients undergoing outpatient shoulder and knee arthroscopy. This study is novel in the field of arthroscopic surgery, and its results will help to guide appropriate postoperative analgesic management following these widely performed procedures

Introduction. Flexor sheath infections require prompt diagnosis, and management with intravenous antibiotics and/or surgical washout followed by physiotherapy. Complication rates as high as 38% have been reported. Methods. A retrospective review was carried out of all patients between January 2014 and May 2021 attending with a suspected or confirmed diagnosis of flexor sheath infection. Age, gender, co-morbidities, cause of infection, management, and subsequent complications recorded. Results. Of 132 patients, 67% were male. Mean age was 50.8 years. A trend towards fewer presentations each year with animal bites, foreign bodies and penetrating trauma as the main cause of infection. 89% (n=117) required admission, 77% (n=101) underwent a surgical washout. 11% (n=15) were treated as an outpatient. 7% (n=9) suffered a complication. Discussion. Whilst flexor sheath washout continues to be the treatment of choice, 23% of patients were managed with intravenous antibiotics, 48% of these purely via an outpatient service. Our overall complication rate was 7%

Myriad protocols exist for isolated Weber B lateral malleolus fractures with a congruent tibiotalar joint on initial radiographs. Stress and weight-bearing radiographs, all at various timepoints, may be employed to identify those injuries that develop significant talar shift but consensus is elusive. This study outlines a safe and reproducible protocol for such injuries, utilising a removable orthosis, immediate weight bearing and standard supine radiographs. A retrospective analysis of a prospective trauma database was analysed to identify patients with an isolated Weber B ankle fracture with adequate presentation radiographs demonstrating a congruent mortise. Patient records and radiographs were evaluated a minimum of 5 years after initial presentation to determine ankle stability, complications, and the burden on outpatient services. Between 2014 and 2016, 657 patients were referred to the specialist trauma clinic from the emergency department. Of the 657, 52 patients had inadequate ED radiographs to determine ankle congruity. At the two-week assessment, 11 of the 52 demonstrated talar shift and required intervention. Therefore 646 patients demonstrated ankle congruity at two weeks after weight bearing. No patient demonstrated talar shift at the six-week assessment. Average number of follow up appointments was 2.4 with 3.5 radiographs. Our new treatment protocol advocates discharge after a single orthopaedic assessment after two weeks of weight bearing. This study supports immediate weight-bearing of Weber B ankle fractures with a congruent mortise in an orthosis. Follow up beyond two weeks is unnecessary and our protocol offers a safe means of significantly reducing the outpatient burden

Abstract. Introduction. Neck of femur (NOF) fracture patients are at risk of developing venous thromboembolisms (VTE). VTE risks could be reduced by adhering to the National Institute for Health and Care Excellence (NICE) recommendation for 1 month of prophylaxis with low molecular weight heparin. This audit aimed to assess and improve local compliance to national guidelines on VTE prophylaxis in NOF fracture patients following discharge. Methods. A retrospective consecutive case series of all NOF fractures treated at our institution from May – July 2021 was conducted. Those not eligible for outpatient VTE prophylaxis were excluded (anticoagulated for other indications, completed prophylactic course in hospital, inpatient death, pharmacological prophylaxis contraindicated). The agent and duration of VTE prophylaxis, and the occurrence of clinically significant VTE or bleeds were recorded. A re-audit was conducted in March 2022. Results. From May – July 2021, only 1/65 (1.5%) patient was discharged on a VTE prophylaxis regime consistent with NICE guidelines (1 enoxaparin, 56 rivaroxaban, 6 apixaban; 58 35-day course, 5 28-day course). A quick-guide document summarising the standard inpatient and outpatient VTE prophylaxis regimes for various orthopaedic indications was designed and widely disseminated. In March 2022, 30/34 (88.2%) patients were discharged with enoxaparin and 24/34 (70.6%) received a 28-day course. There were no cases of clinically significant VTE or bleeds in both cycles. Conclusion. Local compliance to national guidelines improved significantly with the implementation of a standardised VTE prophylaxis protocol. Our quick-guide document is a reproducible way of communicating consensus and ensuring consistency within a department

Abstract. Objectives. Magnetic resonance imaging (MRI) is one of the most widely used investigations for knee pain as it provides detailed assessment of the bone and soft tissues. The aim of this study was to report the frequency of each diagnosis identified on MRI scans of the knee and explore the relationship between MRI results and onward treatment. Methods. Consecutive MRI reports from a large NHS trust performed in 2017 were included in this study. The hospital electronic system was consulted to identify whether a patient underwent x-ray prior to the MRI, attended an outpatient appointment or underwent surgery. Results. 4466 MRI knees were performed in 2017 with 71.2% requested in primary care and 28.1% requested in secondary care. The most common diagnosis was signs of arthritis (55.2%), followed by meniscal tears (42.8%) and ACL tears (8.3%). 49.4% of patients who had an MRI attended outpatients and 15.6% underwent surgery. The rate of knee surgery was significantly higher for patients who had their scans requested in secondary care (32.9% vs 8.9%, p < 0.001). Conclusion. The rate of surgical intervention following MRI is low and given these results it seems unlikely that the scan changes practice in most cases. The rate of surgery and outpatient follow up was significantly higher in scans requested by secondary care. We urge clinicians avoid wasteful use of MRI and recommend the use of plain radiography prior to MRI where arthritis may be present

Introduction. Virtual fracture clinics (VFC's) aim to reduce the number of outpatient appointments while improving the clinical effectiveness and patients experience through standardisation of treatment pathways. With 4.6% of ED admissions due to trauma the VFC prevents unnecessary face to face appointments providing a cost savings benefit to the NHS. Methods. This project demonstrates the importance of efficient VFC process in reducing the burden on the fracture clinics. We completed preformed a retrospective cross-sectional study, analysing two cycles in May (n=305) and September (n=332) 2021. We reviewed all VFC referrals during this time assessing the quality of the referral, if they went on to require a face to face follow up and who the referring health care professional was. Following the cycle in May we provided ongoing education to A&E staff before re-auditing in September. Results. Between the two cycles there was an average 19% improvement in quality of the referrals, significant reduction in number of inappropriate referrals for soft tissue knee and shoulder injuries from 15.1% (n=50) to 4.5% (n=15) following our intervention. There was an 8% increase in number of fracture clinic appointments to 74.4% (n=247), primarily due to an increase number of referrals from nurse practitioners. Radial head fractures were targeted as one group that were able to be successfully managed in VFC, despite this 64% (n=27) of patients were still seen in the outpatient department following VFC referral. Conclusion. Despite the decrease in the number of inappropriate referrals, and the increase in quality of referrals following our intervention. The percentage of VFC referrals in CAVUHB is still higher than other centres in with established VFCs in England. This possibly highlights the need for further education to emergency staff around describing what injuries are appropriate for referral, specifically soft tissue injuries and radial head fractures. In order to optimise the VFC process and provide further cost savings benefits while reducing the strain on fracture clinics
