Purpose: Operative site infections can have catastrophic consequences after orthopaedic surgery. Prevention is particularly difficult due to the large number of factors involved. We describe here an exceptional epidemic of meti-R Staphylococcus aureus (MRSA) operative site infections whose source was successfully identified and eradicated. Material and methods: The epidemic affected seven patients who underwent orthopaedic surgery during a thirteen-month period. All patients developed acute MRSA operative site infection. The epidemic nature of the infections was confirmed by the bacteriological study which identified the causal germ as a specific MRSA strain very different from strains generally identified in hospital infections. The causal strain was sensitive to quinolones and resistant to amikacin. Antibiotic therapy prescribed in all cases was combined with surgical lavage in four patients. Search was undertaken to identify an environmental or human source. An audit of the operating theatre was performed and nasal swabs were obtained from all personnel present at the last operation complicated by operative site infection. One non-medical assistant was found to be a carrier of the same MRSA strain incriminated as the cause of the epidemic. Nasal application of mupirocin successfully eradicated the carrier-state. No new case of operative site infection was noted for more than fourteen months. Discussion: Operative site infections in orthopaedic surgery led to longer inpatient care and can compromise functional outcome. These nosocomial infections have a significant impact on mortality and constitute a major cost burden for hospitals. Prevention, control and treatment of MRSA nosocomial infections is a major challenge in hospitals throughout the world. Most operative site infections are caused by direct contamination during the operation. This epidemic highlights the importance of strict application of rigorous preventive measures not only by the surgical team but also by all healthcare workers and hospital personnel in general. Conclusion: The specific antibiotic susceptibility pattern of a Staphylococcus aureus strain incriminated in several operating site infections enabled identification of the source of the epidemic and its eradication

Aim: Since obesity is thought to be an aetiological factor for SCFE we have looked to see if the ‘Obesity epidemic’ in children has been associated with a similar trend in SCFE. Method: A population based study, using a national database of NHS Scotland activity, was undertaken to analyse trends in SCFE from 1981 to 2005 and to look for a relationship with changes in obesity in Scotland. Data on the body mass indices of Scottish school children have been collected as part of the child Health Surveillance Programme. Results: We found that the incidence of SCFE increased from 3.78 per 100,000 children in 1981 to 9.66 per 100,000 children in 2000 (R. 2. = 0.715) – a two and a half fold increase over two decades. Furthermore, SCFE was seen at younger ages with a fall in the average age at diagnosis from 13.4 to 12.6 years for boys (p=0.007) and 12.2 to 11.6 for girls (p=0.047). SCFE is rare in young children – for 1981–1990 only two children presented with the diagnosis between the ages of six and eight; however for 1991–2000 seven presented in this age group. Along with the rest of the UK, the two decades we studied had seen markedly rising childhood obesity rates in Scotland. The prevalence of overweight (BMI> 85. th. centile) 13–15 year old children doubled from 15% in 1981 to 29% in 2001 and the problem extends to 4 and 5 year olds, although it is not of the same severity. Conclusion: The incidence of SCFE has increase two and a half times in two decades and may well be a consequence of the worsening obesity rates that have occurred over the same period

Background The non-motorised microscooter has become the urban transport of choice for children in Ireland. Recently, Josefson highlighted the rising trend of scooter-related injury in the US and predicted possible significant impacts in human and socioeconomic terms.

Materials and Methods. A prospective study was undertaken of all referrals with scooter injuries to accident and emergency departments and fracture clinics in the first three months of the year. These cases were then reviewed at 6 months post injury

Results: There were 151 microscooter injuries seen in the first 3 months of the year, Forming over 4% of all trauma seen over this period. Eighty nine of the patients (59%) were female, and the mean age at presentation was 8.5 years (range 3–15 years). The peak referral rates for January, February and March measured 48%, 29% and 23% respectively. A survey of attending paediatric outpatients over this period revealed that 75% of households possessed at least 1 scooter, and in those households with children aged between 4 and 14 years, the rate of micoscooter possession increased to 83%. Eighty four children suffered fractures and dislocations, 59 suffered soft tissue injuries, 8 had isolated head injuries. Upper limb fractures and dislocations were the most common injury (75 of 84 bone and joint injuries). Fracture of distal third of radius and ulna, was the most common single injury. upper limb fractures wer seen frequently. A high proportion of these had apex dorsal angulation with or without displacement (Smith deformity). Lower limb fractures were relatively rare. The pattern of soft tissue injuries and lacerations mostly affected the head and neck 25 (17%), the lower limb was involved in 19 (13%) and upper limb in 15 (10%) of patients. No major head injuries occurred. Only 5 patients had any adult supervision at the time of their injury. No children wore any formal protective clothing or apparatus. In the 84 patients who had suffered bony injury, at 6 months, 110 patients (73%) had

Purpose: The aim of the study was to evaluate whether the recognition rates of ACL injuries had improved in the decade following the original paper published by the senior author.

Methods: Prospective data collection using a standard questionnaire on all patients presenting to a dedicated soft tissue knee injury clinic. There were 103 patients with a median age of 31.

Results: 94 out of the 103 patients gave a typical history of an ACL injury. The mean time to referral to this specialist clinic was 92 weeks. The commonest mechanism of ACL injuries was sports (88/103), with soccer making up the vast majority. The correct diagnosis was made by 13% of A& E staff, 30% of GPs and 57% of Orthopaedic surgeons.

Of the 11 patients who had an arthroscopy, 4 were told that they had an ACL injury. None of the 15 who had an MRI scan were told that they had an ACL injury.

Conclusion: Despite the increasing incidence and changes in management, there appears to have been very little improvement in the detection of the ACL injured knee in the last 10 years.

The senior author has treated a series of patients with subtrochanteric and diaphyseal femoral stress fractures associated with long-term alendronate or other bisphosphonate usage. Several patients completely fractured their femurs prior to referral. Most patients had consulted other physicians and were referred for presumed neoplasms. All patients had been diagnosed with osteoporosis and had been treated with bisphosphonates. Their plane radiographs revealed abnormalities that are pathognomonic of bisphosphonate-associated stress fractures. However, due to the subtle nature of these new unfamiliar abnormalities, most were unrecognized as such by clinicians (including experienced ISTA member hip surgeons) and radiologists. This series is presented to illustrate this pattern of impending fracture.

The authors have reviewed and will present a series (n=17) of femoral stress fractures in bisphosphonate-treated patients to illustrate the clinical and radiographic pattern of these stress fractures, and review their treatment.

The most common lesion is a subtrochanteric lateral cortical thickening that in actuality is a horizontal plane “dreaded black line” of a stress fracture with surrounding proximal and distal cortical thickening of the endosteal and periosteal bone. The stress fracture line is obscured unless a near-perfect radiographic projection is obtained. The lesion is best seen with CT scans. MRI scans reveal the stress fracture lines with surrounding edema (Fig 1), which may be misinterpreted as a tumor. Without treatment, a low-impact completed fracture will likely occur.

Many bisphosphonate-associated impending subtrochanteric femoral stress fractures are misdiagnosed as trochanteric bursitis, leading to subsequent displaced subtrochanteric fractures [Fig. 2 - Note subtle impending fracture lesion on right, completed fracture on left]. The clinical and subtle radiographic findings must be recognized by orthopaedic surgeons, particularly hip surgeons, to prevent these complete fractures. These fractures are preventable with internal fixation. Long-term administration of bisphosphonates can have adverse effects, and alternatives to long-term continuous dosing must be investigated to determine optimal administration regimens.

Radiation exposure is a hazard to orthopaedic surgeons, theatre staff and patients intra-operatively. Obesity is becoming a more prevalent problem worldwide and there is little evidence how a patient's body habitus correlates with the radiation doses required to penetrate the soft tissues for adequate imaging.

We aimed to identify if there was a correlation between Body Mass Index (BMI) and radiation exposure intra-operatively.

We performed a retrospective review of 75 patients who underwent sliding hip screw fixation for femoral neck fractures in one year. We recorded Body Mass Index (BMI), screening time, dose area product (DAP), American Society of Anesthesiologists (ASA) grade, seniority of surgeon and complexity of the fracture configuration. We analysed the data using statistical tests.

We found that there was a statistically significant correlation between dose area product and patient's BMI. There was no statistically significant relationship between screening time and BMI. There was no statistical difference between ASA grade, seniority of surgeon, or complexity of fracture configuration and dose area product.

Obese patients are exposed to increased doses of radiation regardless of length of screening time. Surgeons and theatre staff should be aware of the increased radiation exposure during fixation of fractures in obese patients and, along with radiographers, ensure steps are taken to minimise these risks.

Background

We reproduced a frequently cited study performed at our University Hospital that was published in the British Medical Journal in 1981 assessing the extent of “snow and ice” fractures during the winter period.

Firearm injury is a potentially increasing public health problem worldwide. It is increasingly the subject of media and public attention. We aim to analyze the epidemiology, pattern and outcome as experienced.

Data such as age, sex, race, scene and nature of injury, firearm used, alcohol and drug factors, anatomy involved, surgical requirements, transfusion details, ICU/HDU stay, complications, deaths, and outcome were collected from medical notes, WYMAS and Coroners office of all patients who presented with firearm injuries from January 1995 to December 2001. Seventy-eight cases presented to our institution. There were 19 fatalities at the scene of injury. 69 were male. 51 sustained injuries in public places, 20 at their homes and 7 in outdoor areas. Low velocity firearms were involved in 49 cases. 50 were crime related. Alcohol was identified in 34 patients and illicit drugs in 6 cases. 19 cases had bony injury with associated vascular injury in one case. Primary neurological injury was diagnosed in 5 cases. Lower extremities and upper limb injuries accounted for 59% and 26%. 3 had head and neck wounds. 4 patients had thoracic trauma and 5 had abdominal injury. 86% required surgical intervention. 11 patients had a total of 16 complications, the most common being secondary infection. 6% of patients died at the emergency department and 3 after. Chest injuries caused 5 deaths and head wounds caused 3 deaths illustrating criminal intention to cause fatal body harm.

Conclusion: Males in younger age groups are disproportionately affected and the majority were crime- related injuries. Alcohol and other drugs were identified as a significant factor. There has been no significant decrease in the reported cases of firearm injuries or firearm-related deaths after the amendment made in the Firearm Rules in September 1998 (No:1941). The incidence of non-fatal firearm injury is comparable to centres involving similar population.

Revision hip surgery is reportedly rising inexorably yet not all units report this phenomenon. The outcome of 1143 consecutive Corin TaperFit primary hip arthroplasties (957 patients) performed between 1995 and 2010 is presented. The implants were cemented under pressurisation and combined the TaperFit stem with Ogee flanged cups.

Data was gathered from local arthroplasty database and case note review of revised joints. 13 hips have been revised (1.1%). Cumulative prosthesis survival is 0.99 +/− 0.0. Two femoral stems were revised (0.2%); one at 6 months for sepsis, one at 14 days after dislodgment during reduction of dislocation. No revisions were undertaken for aseptic loosening of the stem or cup, nor for thigh pain. 32 patients (32 hips) ≥15 year follow up, 13 survive today and none have been revised (0%). Of the 471 with ≥10 year follow up, 38 were aged ≤50 at time of surgery and 1/38 has been revised to date (PLAD for dislocation).

The strong population stability in this region, supported by independent investigation by Scottish Arthroplasty Project, endorses the accuracy of the data quoted. The low incidence of revision in this cohort, and absence of revision for aseptic loosening (mean follow up 8.03 years +/− SD 3.94; range 18 months to 16yrs 2 months), substantially supports the longevity and use of cemented, double-taper, polished, collarless femoral stems in combination with cemented polyethylene cups in primary hip arthroplasty in all patient age groups.

Aims. To investigate factors that contribute to patient decisions regarding attendance for arthroplasty during the COVID-19 pandemic. Methods. A postal questionnaire was distributed to patients on the waiting list for hip or knee arthroplasty in a single tertiary centre within the UK. Patient factors that may have influenced the decision to attend for arthroplasty, global quality of life (QoL) (EuroQol five-dimension three-level (EQ-5D-3L)), and joint-specific QoL (Oxford Hip or Knee Score) were assessed. Patients were asked at which ‘COVID-alert’ level they would be willing to attend an NHS and a “COVID-light” hospital for arthroplasty. Independent predictors were assessed using multivariate logistic regression. Results. Of 540 distributed questionnaires, 400 (74.1%; 236 awaiting hip arthroplasty, 164 awaiting knee arthroplasty) complete responses were received and included. Less than half (48.2%) were willing to attend for hip or knee arthroplasty while a UK COVID-19 epidemic was in circulation (COVID-alert levels 3 to 5). Patients with worse joint-specific QoL had a preference to proceed with surgery at COVID-alert levels 3 to 5 compared to levels 1 and 2 (hip arthroplasty odds ratio (OR) 1.54 (95% confidence interval (CI) 1.45 to 1.63); knee arthroplasty OR 1.16 (1.07 to 1.26)). The odds of patients with worse joint-specific QoL being willing to attend for surgery at COVID-alert levels 3 to 5 increased further if surgery in a private, “COVID-light” hospital was available (hip arthroplasty OR 3.50 (95% CI 3.26 to 3.71); knee arthroplasty OR 1.41 (95% CI 1.29 to 1.53). Conclusion. Patient decisions surrounding elective surgery have been influenced by the global COVID-19 pandemic, highlighting the importance of patient involvement in ensuring optimized provision of elective surgery during these challenging times.

The coronavirus 2019 (COVID-19) global pandemic has had a significant impact on trauma and orthopaedic (T&O) departments worldwide. To manage the peak of the epidemic, orthopaedic staff were redeployed to frontline medical care; these roles included managing minor injury units, forming a “proning” team, and assisting in the intensive care unit (ICU). In addition, outpatient clinics were restructured to facilitate virtual consultations, elective procedures were cancelled, and inpatient hospital admissions minimized to reduce nosocomial COVID-19 infections. Urgent operations for fractures, infection and tumours went ahead but required strict planning to ensure patient safety. Orthopaedic training has also been significantly impacted during this period. This article discusses the impact of COVID-19 on T&O in the UK and highlights key lessons learned that may help to proactively prepare for the next global pandemic.

Introduction. Due to the opioid epidemic, our service developed a cultural change highlighted by decreasing discharge opioids after lower extremity arthroplasty. However, concern of potentially increasing refill requests exists. As such, the goal of this study was to analyze whether decreased discharge opioids led to increased postoperative opioid refills. Methods. We retrospectively reviewed 19,428 patients undergoing a primary hip or knee arthroplasty at a single institution from 2016–2019. Patients that underwent secondary procedures within that timeframe were excluded. Two-thousand two-hundred and forty-one patients (12%) were on narcotics preoperatively or had chronic pain syndrome. Two reductions in routine discharge narcotics were performed over this timeframe. First, 8,898 patients routinely received 750 morphine milligram equivalents (MMEs). After the first reduction, 4,842 patients routinely received 520 MMEs. After a second reduction, 5,688 patients routinely received 320 MMEs. We analyzed refill rates, refill MMEs, and whether discharge MMEs were associated with refill MMEs in a multivariate model. Results. Opioid refill rates were 28%, 32%, and 33% in each timeframe (p=0.001). Significantly fewer patients received narcotic refills after 6 weeks in the 320 MME group (8%) compared to the 750 MME group (6%, p=0.02). Total refill MMEs reduced significantly from a mean of 282 in the first to 227 in the last timeframe (p<0.001). After controlling for age, sex, BMI, history of anxiety/depression, and procedure type, opioid discharge of <400 MMEs was not a risk factor for increased refill MMEs in opioid-naïve patients (p=0.23). Conclusion. While decrease in MMEs prescribed at discharge after arthroplasty led to a slight increase in the number of opioid refills (5%), there was a reduction in total refill MMEs. Furthermore, less patients received refills beyond 6 weeks postoperatively. This institutional cultural change led to a reduction in opioid prescriptions after primary arthroplasty equivalent to 500,000 oxycodone 5 mg tablets

Obesity is a global epidemic of 2.1 billion people and a well known cause of osteoarthritis. Joint replacement in the obese attracts more complications, poorer outcomes and higher revision rates. It is a reversible condition and the fundamental principles of dealing with reversible medical conditions prior to elective total joint replacement should apply to obesity. The dilemma for orthopaedic surgeons is when to offer surgery in the face of a reversible condition, which if treated may obviate joint replacement and reduce the risk and severity of obesity related disease in both the medical arena and the field of orthopaedics

Despite the widespread success of total hip arthroplasty (THA), postoperative pain management remains a concern. Opioids have classically been administered for pain relief after THA, but their side effect profile, in addition to the cognizance of the growing opioid epidemic, has incited a shift toward alternative pain modalities. Although the nonsteroidal anti-inflammatory drug (NSAID) diclofenac is a promising addition, its impact on immediate THA outcomes has not previously been investigated. Thus, in the present study, we evaluate the effects of adjunctive diclofenac on: 1) postoperative pain intensity, 2) opioid consumption, 3) discharge destination, 4) length of stay, and 5) patient satisfaction in primary THA patients. A retrospective review was performed to identify all patients who underwent primary THA by a single surgeon between May 1 and September 31, 2017. Patients were stratified into a study group (n=25), who were treated with postoperative diclofenac in addition to the standard pain control regimen, and a control group (n=88), who did not receive adjunctive diclofenac. Repeated-measures analysis of variance (ANOVA)/analysis of covariance (ANCOVA) and chi-square/logistic regression analysis were used for continuous and categorical variables, respectively. Patients receiving adjunctive diclofenac were more likely to be discharged home than to inpatient facilities (O.R. 4.02, p=0.049). In addition, patient satisfaction with respect to how well and how often pain was controlled (p= 0.0436 and p=0.0217, respectively) was significantly greater in the diclofenac group. Finally, patients who received diclofenac had lower opioid consumption on postoperative days one and two (−67.2 and −129 mg, respectively, p=0.001 for both). The rapid growth of THA as an outpatient procedure has intensified the urgency of improving postoperative pain management. The present study demonstrates that THA patients receiving adjunctive diclofenac were more likely to be discharged home, had reduced opioid consumption, and experienced greater satisfaction. This will, in turn, decrease complications and total hospital costs, leading to a more cost-effective pain control regimen. In order to further investigate the optimal regimen, future studies comprising larger cohort, as well as a comparison of diclofenac to other NSAIDs, are warranted

HIV and musculoskeletal trauma have reached epidemic proportions in the developing world especially in sub Saharan Africa. The epidemic has adversely affected health care delivery in limited resource settings. We assessed the outcome of HIV+ patients following spinal surgery for fractures and dislocations. Forty seven HIV+ patients were treated surgically over the past three years. The mean age was 32 years (19–53 years) and included 39 males. The dorsolumbar region was affected in 28 patients and the cervical spine in 19. Motor vehicle collisions (34) accounted for 72% of the injuries. Neurology occurred in 49% of patients (23). The mean CD4 count was 426 (range 98–742). The albumen was 29 gm/d? (range 26–34) and the lymphocyte count was 1.6c/cumm range 1.4–1.9). Twenty eight patients had generalized lymphadenopathy and recent weight loss was noted in 11 patients. Fifteen patients were treated for pulmonary TB and seven patients were on ARVs. The dislocations at the cervical spine commonly occurred at C5/6 (8). Three patients required a posterior cervical release with facetectomy prior to anterior cervical plating which was performed in all patients. The dislocations and unstable burst fractures of the dorsolumbar spine were treated by a one/two level posterior fusion. Post-operative sepsis due to S. aureus occurred in 8 (17%) patients. In four patients with deep infection vacuum dressings were used to clear the sepsis. Post-operative sepsis is best avoided by optimization of patients and meticulous surgery

Osteoarthritis (OA) is one of the most common causes of knee pain in the aging population and presents with higher odds with increased BMI. Total knee arthroplasty (TKA) has become the standard of care for the treatment of OA. Over “719,000 TKA's were performed in 2010 in the USA alone, with dramatic economic burden- costing 16,000 USD per TKA” (CDC 2012). Over the past two decades, this cost was compounded by the unknown increasing rate of primary TKA and cannot be explained by the expanding population or worldwide obesity epidemic. These facts raise two key questions: are patients' quality of life expectations higher and driving the TKA rate up, or have surgeons changed their indications and started to operate on less disabled people? Our study aimed to determine the average functional profile for patients undergoing TKA using patient reported Outcome Measure (SF-36), to document if preoperative SF-36 scores have changed over the past two decades, and lastly to asses if patient pre-operative SF-36 scores are lower in in the USA vs the rest of the world. A literature search of Medline, Embase and Cochrane databases was performed extracting data from publishing year 1966 to 2016 with a search date of Dec 12, 2016. Two independent reviewers revised the abstracts and excluded articles with: no TKA, revision TKA, no pre-op SF-36, no SF-36 reported, incomplete scores to calculate SF-36, duplicates, review article, meta-analysis, letter to the editor, conference proceeding or abstract, disagreements were resolved with a third reviewer. All languages were included to maximize the catchment of data. All remaining articles were independently read and excluded if they did not provide data required for our study. Included articles were analyzed for data including: for year of patient enrollment, location (USA vs. non-USA), pre-operative SF-36 mental (MCS) and physical (PCS) component summary, level of evidence. Recorded data was compared post completion to assess inter-observer accuracy as per PRISMA guidelines for meta-analysis. After applying all the exclusion criteria on 923 selected abstracts, a total of 136 articles of which 30 were randomized control trials, were completely reviewed and included in our study. A total of 56,713 patients' physical component scores were analyzed and revealed an overall pre-operative SF-36 physical component score 31.93. When stratifying the data, it was revealed that patients operated in the USA had an average score of 32.3 whereas Non-US countries were 31.7, with no statistical significance. No statistical difference between SF36 scores was seen over time amongst studies of all nations. Based on the results of this study, we have shown that orthopaedic surgeons are performing TKA universally at the same pre-operative scores, independent of country of origin or year of surgery. The indications thus have remained consistent for two decades regardless of the advances in technology. Functional profiles of patients appear similar among US and Non-US countries. Further, we infer that based on pre-operative SF-36 PCS scores, the optimal time to undergo a TKA is when PCS is 31.9 +/−3

The August 2013 Hip & Pelvis Roundup. 360 . looks at: are we getting it right first time?; tantalum augments in revision hip surgery; lower wear in dual mobility?; changing faces changes outcomes; synovial fluid aspiration in MOM hips; taper disease: the new epidemic of hip surgery; the super-obese and THR; and whether well fixed stems can remain in infected hips

Fracture neck of femur (NOF) in elderly is a serious debilitating injury and has been presenting in increasing proportions. Some of these patients are unfortunate to come back with a contralateral injury. We attempted at looking into the incidence of these episodes in a cohort attending our trust and compared various parameters. We retrospectively assessed our hospital theatre data for fracture NOF in patients over 60 years in the last 3 years. We reviewed their demographics, mode of injury, time to contralateral injury, incidence of any other insufficiency fracture, operative procedure and any complications. There were 1435 patients who underwent surgery for fracture NOF over the 3 years. Forty-three of these had bilateral fractures. Females had 3 times more incidence as compared to males; average age at first injury was 84 years and at contralateral side was 85 years. Time between the two injuries ranged from 20 to 855 days (Median 242 days). Almost equal incidence of intra / extracapsular fractures was noted. Contralateral fracture pattern (Intra vs Extracapsular) for the was similar in 34 patients. Twelve patients had an associated insufficiency fracture. Fracture NOF in elderly is a rising epidemic. Only 3% of these patients suffer a contralateral fracture NOF which usually occurs within a year. The fracture pattern is frequently similar to the first fracture in and hence similar implants have been used. Only 21% patients were on bone protection medications. It is rather difficult to identify this small group and hence prevent a second contralateral incident

Background. Opiate abuse is a rapidly growing epidemic in the US, and orthopaedic surgeons are among the highest prescribers. While surgeons have relied heavily on opiates after total hip replacement (THR), our goal was to determine whether a multimodal pain regimen could improve pain control and reduce or even obligate the need for opiates. Methods. In a cluster-randomised, crossover trial, we assigned 235 patients undergoing THR to receive either a multimodal pain regimen with a minimal opiate supply (Group A- 10 tablets only), a conventional multimodal regimen (Group B- 60 tablets), or a traditional opiate regimen without multimodal therapy (Group C- 60 tablets). Clusters were determined by surgeon, with each cluster alternating between regimens in 4-week intervals. The multimodal pain regimen comprised standing-dose acetaminophen, meloxicam, and gabapentin. Primary outcomes were VAS pain and daily opiate use for the first 30 days postoperatively. Secondary outcomes included daily assessments of satisfaction, sleep quality, and opiate-related symptoms, hip function at 1-month, and 90-day adverse events. Results. Daily pain was significantly lower in both multimodal groups, Group A (Coeff −0.81, p=0.003) and Group B (Coeff −0.61, p=0.021). While daily opiate utilization and duration of use was also lower for both Group A (Coeff −0.77, p=0.001) and Group B (Coeff −0.30, p=0.04) compared with Group C, Group A also had significantly lower daily opiate use than Group B (Coeff −0.46, p=0.002), and few prescription refills were required in any group. Opiate-related symptoms, in particular fatigue, were significantly lower in Group A compared to Group C (p=0.005), but Group B and C did not differ (p=0.13). Additionally, both multimodal regimens improved satisfaction and sleep, and there was no difference in hip function or adverse events. Conclusions. While a multimodal pain regimen after THR improved pain control and decreased opiate utilization, patients also receiving a minimal opiate supply had a much greater reduction in opiate use and, consequently, fewer opiate-related adverse effects. It's time to rethink traditional approaches to pain management after elective surgery

Introduction. Opioid abuse is a national epidemic. Traditional pain management after total knee arthroplasty (TKA) relied heavily on opioids. The evidence that in-hospital multimodal pain management (MMPM) is more effective than opioid-only analgesia is overwhelming. There has been little focus on post-discharge pain management. The purpose of this study was to determine whether MMPM after TKA could reduce opioid consumption in the 30-day period after hospital discharge. Methods. This was a prospective, two-arm, comparative study with a provider cross-over design. The first arm utilized a standard opioid-only (OO) prn regimen. The second arm utilized a 30-day MMPM regimen (standing doses of acetaminophen, metaxalone, meloxicam, gabapentin) and opioid medications prn. Surgeons crossed over protocols every four weeks. The primary outcome measure was VAS pain score. Secondary outcome measures included morphine milligram equivalents (MME) consumed, failure of the protocol, and manipulation under anesthesia (MUA). A pre-hoc power analysis was performed for the primary outcome measure and an intent-to-treat analysis was done utilizing a longitudinal mixed model. Results. There were 43 patients in the OO cohort and 39 patients in the MMPM cohort. There was no difference in the baseline demographics or preoperative scores (p=0.94). There was no clinically meaningful difference in VAS score between the two groups at any time. The average opioid consumption at 30-days was 469 and 344 MME's for the OO and MMPM cohorts, respectively (p=0.026). 19/43 (44.2%) patients in the OO cohort failed vs. 4/39 (10.3%) in the MMPM cohort (p=0.002). There was 1 MUA in the OO and none in the MMPM cohort (p=0.338). Discussion. A 30-day post-discharge multimodal pain regimen reduced opioid use after TKA. Opioid-only regimens are at an increased risk of failure to control pain. As a result of this study, multimodal pain management after hospital discharge is standard at our institution
