Introduction. Rapid recovery protocols (RRP) for joint replacements have been shown to improve efficiency, reduce costs, and minimize adverse outcomes in academic health systems. The purpose of this study is to evaluate if RRP can be safely implemented in a community health system for total knee arthroplasty. Methods. This study used a retrospective cohort of 3,608 patients who underwent primary unilateral total knee arthroplasty from January 1, 2013 to December 31, 2014. 60 Patients were excluded because data or surgery could not be verified: BMI less than 18.5 or greater than 60 kg/m∘2 or if the surgical time was less than 45 seconds or greater than 180 minutes, and bilateral surgery. Data was obtained from querying the health system's inpatient database containing information for all joint replacements within the system. Patients were compared in two groups: those who received a RRP after surgery versus those who received traditional post-op care. The main outcome measure was all-cause 30-day readmissions. Multivariate logistic regression was used to calculate the odds for all-cause 30-day readmission for patients who received RRP versus traditional care when controlling for age, gender, race, insurance status (Medicare versus no Medicare), obesity, diabetes, renal disease, tobacco use, and ASA score (less than 3 versus 3 or greater). Results. Patients receiving RRP were readmitted less than those who received traditional care (1.6% versus 3.6%, p<0.001) and had a lower mean length of stay (1.5 versus 3.3 days, p<0.001). When controlling for confounding factors, the odds of 30-day readmission for patients receiving RRP versus traditional care was 0.42 (95% CI 0.26–0.66, p<0.001). Conclusions. Rapid recovery protocols are an effective means of reducing 30-day readmissions and length of stay in patients undergoing primary unilateral total knee arthroplasty in a community setting

Introduction

The advantages of UKA include bone stock preservation, physiologic kinematics, retention of main knee ligaments, improved proprioception, & better functional outcome. A semi-active robotic system using CT-based data combined with intraoperative registration & tactile feedback has the potential for more precise implant placement & alignment. This purpose of this study was to compare robotic-assisted implantation (RAI) with conventional manual implantation (CMI) & to investigate whether this technology could lead to more reliable & reproducible outcomes.

Aims. Is it feasible to conduct a definitive multicentre trial in community settings of corticosteroid injections (CSI) and hydrodilation (HD) compared to CSI for patients with frozen shoulder? An adequately powered definitive randomized controlled trial (RCT) delivered in primary care will inform clinicians and the public whether hydrodilation is a clinically and cost-effective intervention. In this study, prior to a full RCT, we propose a feasibility trial to evaluate recruitment and retention by patient and clinician willingness of randomization; rates of withdrawal, crossover and attrition; and feasibility of outcome data collection from routine primary and secondary care data. Methods. In the UK, the National Institute for Health and Care Excellence (NICE) advises that prompt early management of frozen shoulder is initiated in primary care settings with analgesia, physiotherapy, and joint injections; most people can be managed without an operation. Currently, there is variation in the type of joint injection: 1) CSI, thought to reduce the inflammation of the capsule reducing pain; and 2) HD, where a small volume of fluid is injected into the shoulder joint along with the steroid, aiming to stretch the capsule of the shoulder to improve pain, but also allowing greater movement. The creation of musculoskeletal hubs nationwide provides infrastructure for the early and effective management of frozen shoulder. This potentially reduces costs to individuals and the wider NHS perhaps negating the need for a secondary care referral. Results. We will conduct a multicentre RCT comparing CSI and HD in combination with CSI alone. Patients aged 18 years and over with a clinical diagnosis of frozen shoulder will be randomized and blinded to receive either CSI and HD in combination, or CSI alone. Feasibility outcomes include the rate of randomization as a proportion of eligible patients and the ability to use routinely collected data for outcome evaluation. This study has involved patients and the public in the trial design, dissemination methods, and how to include groups who are underserved by research. Conclusion. We will disseminate findings among musculoskeletal clinicians via the British Orthopaedic Association, the Chartered Society of Physiotherapy, the Royal College of Radiologists, and the Royal College of General Practitioners. To ensure wide reach we will communicate findings through our established network of charities and organizations, in addition to preparing dissemination findings in Bangla and Urdu (commonly spoken languages in northeast London). If a full trial is shown to be feasible, we will seek additional National Institute for Health and Care Research funding for a definitive RCT. This definitive study will inform NICE guidelines for the management of frozen shoulder. Cite this article: Bone Jt Open 2024;5(3):162–173

Total knee arthroplasty has been associated with substantial blood loss in the perioperative period necessitating a substantial risk for blood transfusions. There are various methodologies utilized to decrease postoperative anemia and minimize the need for allogeneic blood transfusions. These include autologous pre-donation, the use of erythropoietin and the use of perioperative cell salvage. Although all of these are successful in decreasing postoperative anemia, there is still a significant risk of allogeneic blood transfusions in the postoperative period. This is a retrospective review of a consecutive series of total knee replacements investigating blood loss and the need for postoperative blood transfusions utilizing MIS surgical techniques and Symphony (tm) platelet gel as the sole means of blood conservation.

Purpose and background. Nearly 70% of UK physiotherapists experience work-related musculoskeletal disorders (WRMSDs) during their career, with a significant proportion occurring in the back and being attributed to patient handling tasks. Evidence suggests that manual handling training alone is ineffective and interventions among nurses indicate that a tailored approach, including targeted exercise (TE), can reduce WRMSD rates. This study aimed to explore physiotherapists’ perspectives of WRMSDs, patient handling, and the role of TE in reducing WRMSDs among physiotherapists. Methods and Results. Key informant interviews were conducted with 4 physiotherapy operational leads and 1 manual handling trainer from NHS Grampian. Interviews were transcribed and Framework Analysis was utilised to identify key themes, including challenges, barriers, and facilitators. Following this, two online focus groups were conducted with 7 qualified NHS physiotherapists across the UK. Views of manual handling training varied across specialities, with some finding it comprehensive and adaptable, and others finding it less applicable to patients in their speciality or community setting. Physiotherapist views on fitness for work varied, with some highlighting the necessity of TE to ensure workforce health whilst others considered exercise to be a personal matter. Facilitators to implementation identified by participants were having support from management and a strong justification for the exercise content. Varied work schedules and facilities were identified as barriers to implementation of a work-based TE intervention. Conclusion. Varying perspectives on TE interventions and barriers to implementation were identified. This work will inform future research to develop TE interventions in consultation with key stakeholders.

Aims. The primary aim of this study was to assess the feasibility of recruiting and retaining patients to a patient-blinded randomized controlled trial comparing corticosteroid injection (CSI) to autologous protein solution (APS) injection for the treatment of subacromial shoulder pain in a community care setting. The study focused on recruitment rates and retention of participants throughout, and collected data on the interventions’ safety and efficacy. Methods. Participants were recruited from two community musculoskeletal treatment centres in the UK. Patients were eligible if aged 18 years or older, and had a clinical diagnosis of subacromial impingement syndrome which the treating clinician thought was suitable for treatment with a subacromial injection. Consenting patients were randomly allocated 1:1 to a patient-blinded subacromial injection of CSI (standard care) or APS. The primary outcome measures of this study relate to rates of recruitment, retention, and compliance with intervention and follow-up to determine feasibility. Secondary outcome measures relate to the safety and efficacy of the interventions. Results. A total of 53 patients were deemed eligible, and 50 patients (94%) recruited between April 2022 and October 2022. Overall, 49 patients (98%) complied with treatment. Outcome data were collected in 100% of participants at three months and 94% at six months. There were no significant adverse events. Both groups demonstrated improvement in patient-reported outcome measures over the six-month period. Conclusion. Our study shows that it is feasible to recruit to a patient-blinded randomized controlled trial comparing APS and CSI for subacromial pain in terms of clinical outcomes and health-resource use in the UK. Safety and efficacy data are presented. Cite this article: Bone Jt Open 2024;5(7):534–542

INTRODUCTION. Early discharge after total joint arthroplasty has started to gain acceptance in select academic centers. The purpose of this study was to compare the risk of readmission of Medicare patients discharged one day after total knee arthroplasty (TKA), versus those discharged two or three days after surgery. Our hypothesis was that patients with length of stay (LOS) of one day would not have a higher risk of readmission in a community setting. METHODS. A hospital impatient database was queried for all unilateral, primary total knee replacements performed on patients 65 years or older from January 1, 2013 to December 31, 2014. A total of 1,117 patients discharged the day after TKA (reduced LOS) were compared with 947 patients discharged POD #2 or 3 (traditional LOS). All cases were performed at a community-based joint replacement center with rapid recovery protocols. Discharge timing and disposition were based on established functional benchmarks judged by physical therapy. The main outcome measure was all-cause 30-day readmissions. Multivariate logistic regression was used to calculate odds ratio for all cause 30-day readmission for reduced versus traditional LOS while controlling for age, gender, race, diabetes mellitus, ASA score (less than 3 versus 3 or greater), discharge disposition (home versus rehab). RESULTS. The 30-day readmission rate for the reduced LOS group was 1.2%, as compared to 3.4% readmission rate for the traditional LOS group (p=.001). In the regression model, the traditional LOS group had an increased risk of readmission (odds ratio 2.10, 95% CI 1.02–4.35, p=0.045) when controlling for confounding factors. DISCUSSION AND CONCLUSIONS. Medicare patients can be discharged safely the day after total knee arthroplasty with no increased risk of 30-day readmission in a community medical center

Early mobilization within the first 12 hours (day zero) of total joint arthroplasty (TJA) has been shown to reduce length of stay (LoS) without risking clinical outcomes, patient safety or satisfaction. The purpose of this study was to investigate associations between the degree of mobilization on day zero (i.e., standing at the bedside versus walking in the hallway) and LoS in TJA patients. In addition, we investigated predictors of LoS and day zero mobilization. A retrospective cohort study was undertaken of the health records of patients in a community hospital setting who had an elective unilateral primary TJA between June 2015 and May 2017 and had mobilized on day zero. The total sample was 283 patients (184 TKA and 99 THA) across four mobilization categories: Sat on beside (n = 76), Stood by bed/marched in place (n = 83), Walked in the room (n = 79), and Walked in hall (n = 45). Analysis of variance found no significant group differences in age, ASA score, Charlson Comorbidity Index score, anesthesia, surgeon, procedure type, pain medication, and patient reported symptoms recorded by physiotherapists. Significantly more women were in the Sat group and significantly more men were in the Hall group (p < .001). Patient reported symptoms of nausea and drowsiness were significantly greater for the Sat group (p < .001). LoS was also significantly different across the groups. Post hoc Tukey comparisons found the Walked Hall group had significantly shorter LoS (M = 2.7 days) than the Sat group (M = 3.9, p < .001), Stood group (M = 3.4, p = .011), and the Walked Room group (M = 3.5, p = .004). A hierarchical regression was performed to determine predictors of LoS. Block 1 consisted of demographic, medical status, and patient reported symptoms as variables. Mobilization was entered in Block 2. The first model was significant (p < .001) and explained 24% of variance in LoS. The final model was also significant (p < .001), accounting for a total of 26% of the variance in LoS. Thus, block 2 (i.e., mobilization) accounted for a small but significant 2% incremental variance (p = .008) beyond the block 1 variables in the prediction of LoS. With mobilization added, only male gender (p = .002), lower BMI (p = .026), and lower ASA scores (p = .006) remained significant predictors of shorter LoS, and the predictive ability of several of the block 1 variables were reduced to non-significant levels. A simultaneous regression model was then used to predict degree of mobilization. The model accounted for 24% of the variance in mobilization (p < .001). Variables significantly associated with a greater degree of mobilization included: younger age, male gender, lower BMI, and fewer symptoms, namely nausea, numbness, lightheadedness, and drowsiness. This study found length of stay was shorter when patients mobilized farther on the day of surgery. Some factors predictive of mobilization may be modifiable. Focusing on symptom management could increase opportunities for farther mobilization on the day of surgery, and thus decrease length of stay

Enhanced Recovery After Surgery (ERAS) is a multimodal perioperative care pathway designed to achieve early recovery for patients undergoing major surgery. ERAS allows for the incorporation of evidence based practices and incorporated a comprehensive assessment of the patient's journey through the surgical process from pre-operative screening through to post-operative care. The purpose of this study was to determine if optimisation of ERAS protocol with pre-operative screening and incorporating patient-specific factors into their post operative care would improve length of stay (LOS) and readmission rates following total joint arthroplasty (TJA) in a Canadian community hospital setting. The study collected clinical, demographic data and the physical status perioperative using the American Society of Anaesthesiologists (ASA) classification on 508 patients who underwent TJA between January and August 2015 and compared similar data from the same time frame in the previous calendar year prior to implementation of the pathway. Cohorts were analysed for length of stay (LOS), readmission rates, Pre-operative assessments (completed by anaesthesia, nursing and pharmacy), relevant labs, patient history (surgery, medical, social), and patient values were all considered when developing a specific patient plan for care post-operatively. A post-operative management tool was used to optimise pain control, post-operative nausea and vomiting, bowel management, diabetes blood glucose control, venous thromboembolism prophylaxis, as well as monitoring parameters specific to patient medical history (e.g. respiratory, cardiac). While in hospital, physiotherapy and nursing were consulted by the pharmacist to assess whether patient's post op management needed to be altered to optimise mobilisation and recovery in hospital. The average patient's LOS and readmission rates in 30 days was analysed to assess the change after implementation of the post-operative management tool based on patient specific factors. A total of 508 patients (mean age: 66 years), ASA classification was 3 or greater for 430 patients. The patients were assessed for LOS, readmission rates in 30 days. The mean LOS decreased from 3.6 to 3.3 days after optimisation of the ERAS protocol (student t test p=0.021). The 30-day readmission rate decreased from 2.9% to 1.4% post intervention (z test p=0.087) when compared to the same time period in the previous calendar year prior to protocol implementation. Overall, the cost savings to optimising the ERAS protocol for the hospital is substantial; with approximately $238 saved per patient. Pre-operative screening and incorporating patient-specific factors into an individualised care plan to optimise the ERAS protocol for TJA reduced mean length of stay without a concomitant increase in readmission rates with significant cost saving

Aims

Deep surgical site infection (SSI) remains an unsolved problem after hip fracture. Debridement, antibiotic, and implant retention (DAIR) has become a mainstream treatment in elective periprosthetic joint infection; however, evidence for DAIR after infected hip hemiarthroplaty is limited.

Aims

A pragmatic multicentre randomized controlled trial, UK FROzen Shoulder Trial (UK FROST), was conducted in the UK NHS comparing the cost-effectiveness of commonly used treatments for adults with primary frozen shoulder in secondary care.

Aims

Perthes’ disease is a condition which leads to necrosis of the femoral head. It is most commonly reported in children aged four to nine years, with recent statistics suggesting it affects around five per 100,000 children in the UK. Current treatment for the condition aims to maintain the best possible environment for the disease process to run its natural course. Management typically includes physiotherapy with or without surgical intervention. Physiotherapy intervention often will include strengthening/stretching programmes, exercise/activity advice, and, in some centres, will include intervention, such as hydrotherapy. There is significant variation in care with no consensus on which treatment option is best. The importance of work in this area has been demonstrated by the British Society for Children’s Orthopaedic Surgery through the James Lind Alliance’s prioritization of work to determine/identify surgical versus non-surgical management of Perthes’ disease. It was identified as the fourth-highest priority for paediatric lower limb surgery research in 2018.

The aim was to determine the longterm results of the Oxford unicompartmental knee replacement implanted by a single surgeon in a community hospital setting. The results of the first 97 cases performed by a single surgeon between Feb 1991 Feb 1999 were retrospectively reviewed. Demographic and operative data were recorded and patients were assessed with Knee Society knee score and x-ray. Ninety seven operations were performed on 83 patients. Antero-medial osteoarthritis was the predominant preoperative diagnosis present in 96, gout was present in 2 and avascular necrosis in one. The average age was 70, follow-up 104.3 months with maximum 170 months. Kaplan-Meier analysis was performed and survival was 88% at 124 months. 20 patients (21 knees) had died and 10 (9 patients) had required revision leaving 65 knees available for review. No cases were lost to follow-up. Of the 10 revisions 7 had been revised to a total knee, 4 for lateral wear or pain, one for femoral loosening, 1 for tibial subsidence and 1 for infection. Four of these patients had a previous high tibial osteotomy. The remaining 3 revisions included 2 1iner exchanges for fracture and wear in one patient with varus knees at 11 years and 1 liner exchange for dislocation. The Oxford UKA gives satisfactory longterm results in antero-medial osteoarthritis. We would caution against using this prosthesis where a previous high tibial osteotomy has been performed

Aims: The purpose of this study was to analyse the clinical and radiological results and revision rate of Oxford II unicompartmental arthroplasty in a community hospital setting. Methods: 46 unicompartmental arthroplasties were evaluated after mean 8.4-year follow-up. Clinical results were analysed according to Knee Society and Lysholm scores. Radiologically tibiofemoral axis and possible radiolucent lines were measured. Kaplan-Meier survivorship curves, using revision of any reason as an end point, were also analysed and compared to overall results from the Finnish Arthroplasty Register. Results: During the follow-up there were six revisions (13.0%): one of them for primary deep infection, menis-ceal bearing was repeatedly dislocated in one knee. Four conversions to TKA were made because of ongoing lateral osteoarthritis and an average time for revision surgery was 63.8 months (1,5- 120 months). The survivorship calculated at þve years was 90.5% (95%Cl 81.6–99.4; 33 cases at risk), and after eight years 87.6% (95%Cl 77.3–97,9; 19 cases at risk). Follow-up showed no clinical or radiological signs of solution of components. The angle of tibiofemoral axis was also not altered signiþcantly during this observation period. Conclusions: We conclude that the unicompartmental Oxford arthroplasty is a potential alternative in the treatment of unicompartmental medial osteoarthritic knee. Indications and patient selection should be carefully considered. The survivorship was in accordance with most of the previous series

Aim: The purpose of this report was to analyse the clinical and survivorship results and revision rates of Bichat III uncemented total hip arthroplasty in a community hospital setting. Poor results are rarely published what may have effect on the results of meta-analyses done on hip replacement surgery. At the time of selecting the prosthesis there were no reports published on this particular model. Methods: Between 1987 and 1990 þftyþve patients (57 hips) were operated using the Bichat III endoprosthesis. The prosthesis has a ßuted, anatomic and non-porous Ti femur, and a threaded nonporous acetabular cup. There were 25 male and 30 female patients. Mean age of the male patients was 62 (40–75) and that for the female 61 years (43–82). The indication for operation was primary arthrosis in 45, posttraumatic arthrosis in 5, LPC in 2 cases, and rheumatoid arthritis, AVN and CHD one each. All the operations were made using the Hardingen approach. For the survivorship analysis the patients were traced from the Finnish Arthroplasty Register and Kaplan-Meir survival was calculated for all the 57 patients with the 95% Cl. Those not revised until 31st December 2001 were called for clinical and radiological examination. The mean follow-up time was 12,7 years (11,4–14,2). Results: During the follow-up 16 patients died (28%), and revision was done on 21 patients (37%) after a mean follow-up time of 7,2 years (3,6–11,3). Seventeen patients arrived to the clinical follow-up; of those only 10 cases were without any radiological signs of loosening. For all the patients re-examined the Mayo Clinics Hip Score was 50.8 in average ((5–75), and that for those with radiological signs of loosening 46,3 (16–71). The survivorship calculated at ten years was 57,0% (95%Cl 42,5–71,6; 22 hips at risk). Typical features at revision were total loosening of both components, marked metallosis and breakage of the polyethylene liner. Conclusions: Our results are in accordance with other reports with uncemented, non-porous coated components, as well as with those of the screw þxed acetabular cups. Also the reports from other Nordic arthroplasty registers speak favour of the non-acceptable results with such concepts of THA. Publication of also the negative results of THA may decrease risk of sc. publication bias. We conclude that until now there is sufþcient evidence that porous coating on both components of hip endoprosthesis is crucial for reliable þxation of uncemented components. Prosthesis selection should be made on a well documented basis and trials should be made in arthroplasty centers and on a prospective and randomized basis
