ABSTRACT
INTRODUCTION: Perioperative bleeding increases morbidity and mortality in sarcoma patients. Tranexamic acid (TXA), an antifibrinolytic, is widely utilized in non-sarcoma orthopaedic surgeries, but its adoption in sarcoma surgery is hindered by concerns about thrombotic events. METHODS: Searches in Ovid MEDLINE, EMBASE, and CENTRAL were performed without date restrictions. Inclusion criteria encompassed sarcoma patients undergoing surgery with TXA intervention. Two authors independently screened studies, resolved conflicts, and assessed biases. RESULTS: Eight studies met inclusion criteria, comprising 2142 patients. TXA administration varied in dose and timing across studies. Meta-analysis revealed significantly reduced mean blood loss with TXA of -462.5 mL ([95% confidence interval [CI: -596.7, -328.31], p < 0.001) but no difference in transfusion rates (odds ratio [OR] = 0.51 [95% CI: 0.14-1.89]) or venous thromboembolism events (OR = 0.93 [95% CI: 0.40, 2.16]). Study biases were predominantly moderate to high due to retrospective designs and lack of control for confounders. Quality of reporting varied, with limitations identified in outcome reporting and effect size estimation. CONCLUSIONS: Despite evidence of reduced blood loss, the absence of prospective studies limits conclusive recommendations on TXA use in sarcoma surgery. Further research is warranted to determine optimal TXA regimens and assess safety concerns regarding thrombotic events in this patient population.
ABSTRACT
BACKGROUND AND OBJECTIVES: Intraoperative frozen section analysis is commonly used to evaluate marrow margins during extremity bone sarcoma resections, but its efficacy in the era of magnetic resonance imaging is debated. This study aimed to compare the accuracy of intraoperative frozen section assessment with final pathology, assess its correlation with gross intraoperative margin assessment, and evaluate its impact on surgical decision making. METHODS: Consecutive patients undergoing extremity bone sarcoma resections from 2010 to 2022 at a single sarcoma center were included. Intraoperative frozen section and gross margin assessments were compared to final pathology using positive predictive values (PPV) and negative predictive values (NPV). Changes in surgical decisions due to positive intraoperative margins were recorded. RESULTS: Of 166 intraoperative frozen section marrow margins, four were indeterminant/positive, with two false positive/indeterminant findings and two false negatives compared to final pathology. Gross intraoperative assessment had no false positives and two false negatives. Frozen section analysis yielded a PPV of 50% (95% confidence interval [CI]: 16%-84%) and NPV of 98.8% (95% CI: 97%-100%), while gross assessment had a PPV of 100% (95% CI: 16%-100%) and NPV of 98.8% (95% CI: 97%-100%). Positive frozen section margins led to additional resections in three of four cases. CONCLUSIONS: Intraoperative frozen section analysis did not offer added clinical value beyond gross margin assessment in extremity bone sarcoma resections. It exhibited a low PPV and led to unnecessary additional resections. Gross intraoperative assessment proved adequate for margin evaluation, potentially saving time and resources.
ABSTRACT
BACKGROUND: Given the paucity of data, the objective of this study is to evaluate the association between obesity and major wound complications following pelvic bone sarcoma surgery specifically. METHODS: Patients who underwent pelvic resection for bone sarcoma from 2005 to 2021 with a minimum 6-month follow-up were reviewed. Patients with benign tumors, primary soft tissue sarcomas, local recurrence at presentation, pelvic metastatic disease, and underweight patients were excluded. A major wound complication was defined as the need for a secondary debridement procedure. Differences in baseline demographics, surgical factors, postoperative complications, and functional outcomes were compared between obese and nonobese patients. A multivariate logistic regression was performed to identify independent risk factors for major wound complications, and a Kaplan-Meier analysis to estimate overall survival between both groups. RESULTS: Of the 93 included patients, 21 were obese (body mass index ≥ 30 kg/m2). The obesity group had a significantly higher rate of major wound complication (52% vs. 26%, p = 0.034) and a lower Toronto Extremity Salvage Score at 1-year postoperatively (47.5 vs. 71.4, p = 0.025). Obesity was the only independent risk factor in the multivariate analysis. No differences in overall survival were demonstrated between groups. CONCLUSIONS: Obesity is a significant risk factor for major wound complications in pelvic bone sarcoma treatment. This highlights the importance of careful perioperative optimization and wound management.

PURPOSE: To identify risk factors associated with increased postoperative opioid consumption and inferior pain outcomes following knee and shoulder arthroscopy. METHODS: Using the data set from the NonOpioid Prescriptions after Arthroscopic Surgery in Canada (NO PAin) trial, eight prognostic factors were chosen a priori to evaluate their effect on opioid consumption and patient-reported pain following arthroscopic knee and shoulder surgery. The primary outcome was the number of oral morphine equivalents (OMEs) consumed at 2 and 6 weeks postoperatively. The secondary outcome was patient-reported postoperative pain using the Visual Analogue Scale (VAS) at 2 and 6 weeks postoperatively. A multivariable linear regression was used to analyse these outcomes with eight prognostic factors as independent variables. RESULTS: Tobacco usage was significantly associated with higher opioid usage at 2 (p < 0.001) and 6 weeks (p = 0.02) postoperatively. Former tobacco users had a higher 2-week (p = 0.002) and cumulative OME (p = 0.002) consumption compared to current and nonsmokers. Patients with a higher number of comorbidities (p = 0.006) and those who were employed (p = 0.006) reported higher pain scores at 6 weeks. Patients in the 'not employed/other' category had significantly lower pain scores at 6 weeks postoperatively (p = 0.046). CONCLUSION: Former smoking status was significantly associated with increased post-operative opioid consumption following knee and shoulder arthroscopy at 2 and 6 weeks postoperatively. Increased pain was found to be significantly associated with employment status and an increasing number of comorbidities at 6 weeks postoperatively. These findings can aid clinicians in identifying and mitigating increased opioid utilization as well as worse pain outcomes in high-risk patient populations. LEVEL OF EVIDENCE: Level III, cohort study.
ABSTRACT
INTRODUCTION: Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis. OBJECTIVE: A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care. METHODS: A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today. CONCLUSION: Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided.

PURPOSE: Platelet-rich plasma (PRP) represents a highly profitable biological therapy. Platelet-rich plasma is widely used to treat musculoskeletal disorders despite mixed evidence of its efficacy. As evidenced by literature from other domains, industry funding may influence the results of clinical trials. The objective of the current study was to determine the association between industry funding and positive results for randomized controlled trials (RCTs) assessing the efficacy of PRP in musculoskeletal disorders. METHODS: A search of four databases was conducted. Included studies were RCTs comparing PRP to any non-PRP comparator in adults (18 years old or over) with musculoskeletal disorders and had full text available in English. Studies were excluded if they were published before 2016 or were non-human trials. A multivariate binomial logistic regression model was created to explore predictors of statistically significant findings. Covariates included the presence of industry funding, sample size, and length of study follow-up. 1440 records were screened with 87 trials included in the final analysis. RESULTS: Of the 87 studies, 61 (70%) reported a statistically significant primary outcome. The presence of industry funding was not predictive of a statistically significant primary outcome [OR = 0.36, 95% CI 0.096-1.36, (n.s.)]. Studies that did not state whether industry funding was present had a higher chance of reporting a statistically significant primary outcome (OR = 3.61, 95% CI 1.1-11.9, p = 0.035). Sample size and length of follow-up were not predictive of a statistically significant primary outcome. CONCLUSION: The results of the current study conclude that industry funding had no impact on the reporting of positive results for RCTs investigating PRP in musculoskeletal disorders. However, not disclosing sources of funding was associated with a higher likelihood of reporting positive results. The results of trials that fail to disclose funding sources should be interpreted with caution in the PRP literature. LEVEL OF EVIDENCE: I.

PURPOSE: The purpose of this study was to determine the cost-effectiveness of antibiotic-laden bone cement (ALBC) in primary total knee arthroplasty (TKA) from the perspective of a single-payer healthcare system. METHODS: A cost-utility analysis (CUA) was performed over a 2-year time horizon comparing primary TKA with either ALBC or regular bone cement (RBC) from the perspective of the single-payer Canadian healthcare system. All costs were in 2020 Canadian dollars. Health utilities were in the form of quality-adjusted life years (QALYs). Model inputs for cost, utilities and probabilities were derived from the literature as well as regional and national databases. One-way deterministic sensitivity analysis was performed. RESULTS: Primary TKA with ALBC was found to be more cost-effective compared to primary TKA with RBC with an incremental cost-effectiveness ratio (ICER) of -3,637.79 CAD/QALY. The use of routine ALBC remained cost-effective even with cost increases of up to 50% per bag of ALBC. TKA with ALBC was no longer cost-effective if the rate of PJI following this practice increased 52%, or the rate of PJI following the use of RBC decreased 27%. CONCLUSIONS: The routine use of ALBC in TKA is a cost-effective practice in the single-payer Canadian healthcare system. This remains to be the case even with a 50% increase in the cost of ALBC. Policy makers and hospital administrators of single-payer healthcare systems can leverage this model to inform their local funding policies. Future prospective reviews and randomized controlled trials from the perspective of various healthcare models can further shed light on this issue. LEVEL OF EVIDENCE: III.

BACKGROUND: The influence of socioeconomic status on outcomes following total joint arthroplasty (TJA) in the Canadian single-payer healthcare system is yet to be elucidated. The objective of the present study was to evaluate the impact of socioeconomic status on TJA outcomes. METHODS: This was a retrospective review of 7,304 consecutive TJA (4,456 knees and 2,848 hips) performed between January 1, 2001 and December 31, 2019. The primary independent variable was the average census marginalization index. The primary dependent variable was functional outcome scores. RESULTS: The most marginalized patients in both the hip and knee cohorts had significantly worse preoperative and postoperative functional scores. Patients in the most marginalized quintile (V) showed a decreased odds of achieving a minimal important difference in functional scores at 1-year follow-up (odds ratio [OR] 0.44; 95% confidence interval [CI] [0.20, 0.97], P = .043). Patients in the knee cohort in the most marginalized quintiles (IV and V) had increased odds of being discharged to an inpatient facility with an OR of 2.07 (95% CI [1.06, 4.04], P = .033) and OR of 2.57 (95% CI [1.26, 5.22], P = .009), respectively. Patients in the hip cohort in V quintile (most marginalized) had increased odds of being discharged to an inpatient facility with an OR of 2.24 (95% CI [1.02, 4.96], P = .046). CONCLUSION: Despite being a part of the Canadian universal single-payer healthcare system, the most marginalized patients had worse preoperative and postoperative function, and had increased odds of being discharged to another inpatient facility.

BACKGROUND: Although periprosthetic joint infection (PJI) is a serious complication following a total joint arthroplasty procedure, there remains uncertainty regarding the diagnosis of PJI due to the lack of a globally accepted, standardized definition. The goal of this review is to critically analyze the quality of the evidence used for the novel 2018 MSIS PJI definition and identify gaps and limitations with using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. METHODS: References from the modified 2018 MSIS definition for PJI by Parvizi et al. were retrieved and manually reviewed. A total of 11 studies were assessed using a validated QUADAS-2 tool. RESULTS: Many included studies had an unclear or high risk of bias for the Index Test domain due to a lack of blinding and lack of prespecified thresholds. A majority of studies utilized Youden's J statistic to optimize the thresholds which may diminish external validity. Likewise, several studies were assessed to have an unclear and high risk of bias for the Flow and Timing domain primarily due to a lack of reporting and a large number of exclusions. Overall, there was a low risk of bias for the choice of reference standard, its conduct and interpretation, as well as for the Patient Selection domain. CONCLUSION: Although the literature used for the MSIS 2018 PJI definition is fraught with potential sources of bias, there may be a trend toward an improvement in the quality of evidence when compared to the earlier definition of PJI.

PURPOSE: The treatment of giant cell tumors (GCT) of the distal radius remains challenging, with no consensus on the optimal surgical management. Surgical management remains the mainstay of treatment with options including intralesional curettage and en-bloc resection with reconstruction. The objective of this systematic review and meta-analysis was to evaluate and compare the outcomes of these two procedures. METHODS: Using OVID-Medline and Embase databases, a systematic literature search was performed. Comparative studies, assessing intralesional curettage and en-bloc resection in patients with GCTs of the distal radius, were included. Data regarding rates of local recurrence, metastasis, overall complications, and functional outcomes, were collected and analyzed. The ROBINS-I tool was utilized for risk of bias appraisal within each study outcome. RESULTS: Thirteen studies (n = 373 patients) reporting on 191 intralesional curettage procedures and 182 en-bloc resections were included in the analysis. The average age of participants was 31.9 (SD ± 2.4) years and average follow-up was 7.1 (SD ± 3.6) years. Patients that underwent intralesional curettage were more likely to develop local recurrence (Risk Ratio (RR) 3.3, 95% CI, [2.1, 5.4], p < 0.00001) when compared to patients that underwent en-bloc resection. In Campanacci grade 3 lesions, the risk for local recurrence was 5.9 (95% CI, [2.2, 16.3], p = 0.0006) times higher in patients that received intralesional curettage. Patients that underwent intralesional curettage showed an 84% reduction in the relative risk of developing overall complications compared to en-bloc resection (95% CI, [0.1, 0.4], p < 0.00001), and a larger decrease in Visual Analog Scale and lower Disabilities of the Arm, Shoulder, and Hand (DASH) scores (p < 0.00001). Risk ratio for developing a local recurrence, with PMMA versus bone graft following an intralesional procedure was not significant (RR 1.2, 95% CI, [0.6, 2.6], p = 0.62). CONCLUSIONS: In the surgical management of GCT of the distal radius, intralesional curettage increased local recurrence compared to en-bloc resection with reconstruction, particularly in grade 3 tumors. However, it led to significantly fewer operative complications, lower pain scores, and improved functional outcomes compared to en-bloc resection. Both treatment options remain relevant in the contemporary management of GCTs of the distal radius. Surgical decision making should include both patient and tumor factors when determining the optimal treatment strategy for these patients. LEVEL 3 EVIDENCE: Meta-analysis of Level 3 studies.

INTRODUCTION: Sarcoma patients undergoing surgical resection and endoprosthetic reconstruction often receive neoadjuvant chemotherapy (NACT). The objective of the current study was to determine if the timing of NACT impacts the rates of surgical site infections (SSI) and reoperations. METHODS: This study was a secondary analysis of the recently published Prophylactic Antibiotic Regimens in Tumor Surgery trial. Patients who underwent NACT, tumor resection, and endoprosthetic reconstruction for a bone or soft tissue sarcoma were included. Multivariate Cox proportional hazards regression models were created to evaluate if NACT timing was predictive of SSI or reoperations. RESULTS: Overall, 216 patients from 39 clinical sites were included in the analysis. The most common diagnosis was osteosarcoma (75%), followed by Ewing's sarcoma (16%). The median time from completion of NACT to surgery was 24 days (interquartile range 15-42 days). Eighty-five (39%) patients underwent surgery within 3 weeks of completing NACT, 78 (36%) underwent surgery 3-6 weeks after completing NACT, and 53 (22%) patients underwent surgery > 6 weeks after completion of NACT. The timing of NACT did not impact SSI rates or reoperation rates. Longer operative time was an independent predictor of both SSI [hazard ratio (HR) per hour of 1.21, 95% confidence interval (CI) 1.07-1.40; p = 0.002] and reoperation rates (HR of 1.15 per hour, 95% CI 1.03-1.28; p = 0.014). CONCLUSION: The timing of surgery following NACT varied considerably. Chemotherapy timing did not impact SSI or reoperations in patients undergoing surgical resection and endoprosthetic reconstruction in sarcoma patients.

OBJECTIVE: An evolved understanding of the pathophysiology of greater trochanteric pain syndrome has led to a number of proposed nonoperative management strategies. The objective of this review was to compare the efficacy of the various nonoperative treatments for greater trochanteric pain syndrome (GTPS). DESIGN: Systematic review and network meta-analysis. SETTING: PubMed, Embase, CENTRAL, SCOPUS, and Web of Science were searched to January 2020. PATIENTS: Patients undergoing nonoperative treatment for GTPS. INTERVENTIONS: Nonoperative treatment strategies for GTPS including injections of corticosteroids, platelet-rich plasma, hyaluronic acid, dry needling, and structured exercise programs and extracorporeal shockwave therapy. MAIN OUTCOME MEASURES: Pain and functional outcomes. Bayesian random-effects model was performed to assess the direct and indirect comparison of all treatment options. RESULTS: Thirteen randomized controlled trials and 1034 patients were included. For pain scores at 1 to 3 months follow-up, both platelet-rich plasma (PRP) and shockwave therapy demonstrated significantly better pain scores compared with the no treatment control group with PRP having the highest probability of being the best treatment at both 1 to 3 months and 6 to 12 months. No proposed therapies significantly outperformed the no treatment control group for pain scores at 6 to 12 months. Structured exercise had the highest probability of being the best treatment for improvements in functional outcomes and was the only treatment that significantly improved functional outcome scores compared with the no treatment arm at 1 to 3 months. CONCLUSION: Current evidence suggests that PRP and shockwave therapy may provide short-term (1-3 months) pain relief, and structured exercise leads to short-term (1-3 months) improvements in functional outcomes.

PURPOSE: The use of virtual reality (VR) based rehabilitation has increased substantially within orthopedic surgery, particularly in the field of total knee arthroplasty (TKA). The objective of this systematic review and meta-analysis was to compare patient-reported outcomes and cost analyses from randomized controlled trials (RCT) utilizing VR-based rehabilitation in patients following TKA. METHODS: MEDLINE, EMBASE, and Cochrane databases were searched for RCTs involving VR-based rehabilitation following TKA. Quantitative synthesis was conducted for pain scores and functional outcomes. Narrative outcomes were reported for results not amenable to quantitative synthesis. RESULTS: A total of 9 RCTs with 835 patients were included with follow-up ranging from 10 days to 6 months postoperatively. No differences in pain scores were demonstrated between VR-based and traditional rehabilitation at 2 weeks and 3 months postoperatively. VR-based rehabilitation demonstrated improved functional outcomes at 12 weeks (n = 353) postoperatively [mean difference (MD) - 3.32, 95% confidence interval (CI) - 5.20 to - 1.45, moderate certainty evidence] and 6 months (n = 66) postoperatively [MD - 4.75, 95% CI - 6.69 to - 2.81, low certainty evidence], compared to traditional rehabilitation. One trial demonstrated significant cost savings with the use of VR-based rehabilitation. CONCLUSIONS: VR-based rehabilitation for patients undergoing TKA represents an evolving field that may have advantages over traditional therapy for some patients. The current review is limited by the low quality of evidence in the literature. This is a rapidly evolving field with more trials needed to determine the impact of VR-based rehabilitation on patients undergoing TKA. LEVEL OF EVIDENCE: Level I; meta-analysis of randomized controlled trials.

BACKGROUND: Current literature suggests that 8%-35% of patients undergoing total hip arthroplasty (THA) undergo a subsequent contralateral THA. This study aims to determine if functional outcomes after primary THA predict outcomes in the subsequent primary THA of the contralateral side. METHODS: A retrospective cohort of patients undergoing staged bilateral primary THA was reviewed. The Oxford Hip Score (OHS) was utilized as the functional outcome measurement tool and was assessed preoperatively and at one year postoperatively. The minimal clinically important difference (MCID) was assessed. Based on the first-side THA one-year outcomes, the odds of maintaining an MCID, or not, for the second-side THA were determined. RESULTS: The study cohort consisted of 551 patients and 1102 primary THAs. The average postoperative OHSs were similar after the first and second THA. Patients achieving the MCID with the first-side surgery were 2.6 times (95% confidence interval 1.0 to 6.64, P = .04) more likely to achieve the MCID for the second-side surgery than patients failing to reach the MCID for their first-side surgery. After the first THA, 29 (5.3%) patients failed to reach the predefined MCID for the OHS compared with 54 (9.8%) patients undergoing their second THA (odds ratio: 1.96 [95% confidence interval: 1.23 to 3.1], χ2 = 8.14, P = .005). CONCLUSIONS: Functional outcomes after the first THA are predictive of functional outcomes of the second THA. Patients are more likely to achieve a clinically significant improvement after their first THA related to higher preoperative OHSs before the second THA.

Importance: In 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. Objective: To evaluate the effect of a multimodal, opioid-sparing approach to postoperative pain management compared with the current standard of care in patients undergoing arthroscopic shoulder or knee surgery. Design, Setting, and Participants: This randomized clinical trial was performed at 3 clinical sites in Ontario, Canada, and enrolled 200 patients from March 2021 to March 2022 with final follow-up completed in April 2022. Adult patients undergoing outpatient arthroscopic shoulder or knee surgery were followed up for 6 weeks postoperatively. Interventions: The opioid-sparing group (100 participants randomized) received a prescription of naproxen, acetaminophen (paracetamol), and pantoprazole; a limited rescue prescription of hydromorphone; and a patient educational infographic. The control group (100 participants randomized) received the current standard of care determined by the treating surgeon, which consisted of an opioid analgesic. Main Outcomes and Measures: The primary outcome was postoperative oral morphine equivalent (OME) consumption at 6 weeks after surgery. There were 5 secondary outcomes, including pain, patient satisfaction, opioid refills, quantity of OMEs prescribed at the time of hospital discharge, and adverse events at 6 weeks all reported at 6 weeks after surgery. Results: Among the 200 patients who were randomized (mean age, 43 years; 73 women [38%]), 193 patients (97%) completed the trial; 98 of whom were randomized to receive standard care and 95 the opioid-sparing protocol. Patients in the opioid-sparing protocol consumed significantly fewer opioids (median, 0 mg; IQR, 0-8.0 mg) than patients in the control group (median, 40.0 mg; IQR, 7.5-105.0; z = -6.55; P < .001). Of the 5 prespecified secondary end points, 4 showed no significant difference. The mean amount of OMEs prescribed was 341.2 mg (95% CI, 310.2-372.2) in the standard care group and 40.4 mg (95% CI, 39.6-41.2) in the opioid-sparing group (mean difference, 300.8 mg; 95% CI, 269.4-332.3; P < .001). There was no significant difference in adverse events at 6 weeks (2 events [2.1%] in the standard care group vs 3 events [3.2%] in the opioid-sparing group), but more patients reported medication-related adverse effects in the standard care group (32% vs 19%, P = .048). Conclusions and Relevance: Among patients who underwent arthroscopic knee or shoulder surgery, a multimodal opioid-sparing postoperative pain management protocol, compared with standard opioid prescribing, significantly reduced postoperative opioid consumption over 6 weeks.

BACKGROUND: The direct anterior approach (DAA) has increased in popularity in recent years. Proponents cite its muscle-sparing approach and purported reduction in pain and improvement in function when compared to the traditional surgical approaches. There remains controversy surrounding the validity of these claims. The objective of this study was to compare the common total hip surgical approaches in terms of pain scores, functional outcomes, opioid use and complications within the first 12 weeks postoperatively. METHODS: A network meta-analysis of randomized controlled trials (RCT) comparing postoperative outcomes of different surgical approaches in primary THA up to 12 weeks was performed. PubMed, MEDLINE, Embase, Web of Science and SCOPUS were systematically searched from inception to May 2020. Outcomes included pain scores, functional outcome scores, length of stay (LOS), complications and opioid consumption. RESULTS: Twenty-five RCTs (n = 2339) were included. The DAA demonstrated statistically significant improvement in Harris Hip Scores at 6 weeks when compared to the posterior and direct lateral approaches. The DAA reduced pain scores on postoperative day 2 and at 2 weeks compared to the direct lateral approach. The anterolateral approach was found to have a significantly shorter LOS compared to the other major surgical approaches. The differences in functional outcomes or pain scores did not surpass conventional cutoffs for a minimal clinically important difference. CONCLUSION: The DAA led to functional improvements at 6 weeks compared to the posterior and direct lateral approaches and reduced postoperative pain compared to the direct lateral approach. However, these improvements failed to reach clinical significance. All major surgical approaches led to large improvements in function by 12 weeks with relatively low complication rates. Whether a short-term statistically significant improvement in function is sufficiently patient important to recommend DAA as a standard remains uncertain.

OBJECTIVE: Intra-articular (IA) injections represent a commonly used modality in the treatment of hip osteoarthritis (OA). Commonly used injections include corticosteroids (CCS), hyaluronic acid (HA) and platelet-rich plasma (PRP). A network meta-analysis allows for comparison among more than two treatment arms and uses both direct and indirect comparisons between interventions. The objective of this network meta-analysis is to compare the efficacy of the various IA injectable treatments in treating hip OA at up to 6 months of follow-up. DESIGN: This is a systematic review and network meta-analysis. Bayesian random-effects model was performed to assess the direct and indirect comparisons of all treatment options. DATA SOURCES: PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus and Web of Science, from inception to October 2019. ELIGIBILITY CRITERIA FOR SELECTED STUDIES: Randomised controlled trials assessing the efficacy of CCS, HA, PRP and placebo in the form of IA saline injection for patients with hip OA. RESULTS: Eleven randomised controlled trials comprising 1353 patients were included. For pain outcomes at both 2-4 and 6 months, no intervention significantly outperformed placebo IA injection. For functional outcomes at both 2-4 and 6 months, no intervention significantly outperformed placebo IA injection. Regarding change from baseline at 2-4 months and 6 months, pooled data demonstrated that all interventions (including placebo), with the exception of HA+PRP, led to a clinically important improvement in both pain, exceeding the minimal clinically important difference. CONCLUSION: Evidence suggests that IA hip saline injections performed as well as all other injectable options in the management of hip pain and functional outcomes.

PURPOSE: The opioid epidemic has prompted an emphasis on investigating opioid-sparing alternatives for pain management following knee arthroscopy. This review evaluated the effects of perioperative nonopioid adjunct analgesia on postoperative opioid consumption and pain control in patients undergoing knee arthroscopy. METHODS: A systematic review and meta-analysis was performed using the following databases: PubMed, Embase, Web of Science, MEDLINE, and SCOPUS. Prospective comparative studies assessing the efficacy of various perioperative nonopioid analgesic strategies in patients undergoing knee arthroscopy were included. Twenty-five studies (n = 2408) were included. RESULTS: Pre-emptive nonopioid pain medications demonstrated a reduction in cumulative postoperative oral morphine equivalent (OME) consumption by 11.8 mg (95% CI - 18.3, - 5.4, p ≤ 0.0001) and VAS pain scores by 1.5 (95% CI - 2.3, - 0.7, p < 0.001) at 24 h compared to placebo. Postoperative nonopioid pain medications significantly reduced cumulative postoperative OME consumption by 9.7 mg (95% CI - 14.4, - 5.1, p < 0.001) and VAS pain scores by 1.0 (95% CI - 1.354, - 0.633, p < 0.001) at 24 h compared to placebo. Saphenous nerve blocks significantly reduced cumulative postoperative OME consumption by 6.5 mg (95% CI - 10.3, - 2.6, p = 0.01) and VAS pain scores by 0.8 (- 1.4, - 0.3, p = 0.03) at 24 h compared to placebo. Both preoperative patient education and postoperative cryotherapy reduced postoperative opioid consumption. CONCLUSION: Perioperative nonopioid pharmacotherapy, saphenous nerve blocks, and cryotherapy for patients undergoing knee arthroscopy significantly reduce opioid consumption and pain scores when compared to placebo at 24 h postoperatively. These interventions should be considered in efforts to reduce opioid consumption in patients undergoing knee arthroscopy. More research is needed to determine which interventions can reduce pain outside of the immediate postoperative period and the potential synergistic effects of combining interventions.

BACKGROUND: The relationship among pain catastrophizing, emotional disorders, and total joint arthroplasty (TJA) outcomes is an emerging area of study. The purpose of this study is to examine the association of these factors with 1-year postoperative pain and functional outcomes. METHODS: A prospective cohort study of preoperative TJA patients using the Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale (HADS-A/HADS-D) was conducted. Postoperative outcomes included Visual Analog Scale (VAS) pain, Oxford, Harris Hip (HHS) and Knee Society (KSS) scores. Median regression was used to assess the pattern of relationship among preoperative clinically relevant catastrophizing (CRC) pain, abnormal HADS, and 1-year postoperative outcomes. RESULTS: We recruited 463 TJA patients, all of which completed 1-year follow-up. At 1 year, CRC-rumination (adjusted median difference 1; 95% confidence interval [CI] 0.31-1.69, P = .005) and abnormal HADS-A (adjusted median difference 1; 95% CI 0.36-1.64, P = .002) were predictors of VAS pain, CRC magnification a predictor of HHS/KSS (adjusted median difference 1.3; 95% CI 5.23-0.11, P = .041), and abnormal HADS-A a predictor of Oxford (adjusted median difference 3.68; 95% CI 1.38-5.99, P = .002). CRC patients demonstrated inferior VAS pain (P = .001), Oxford (P < .0001), and HHS/KSS (P = .025). Abnormal HADS patients demonstrated inferior postoperative VAS (HADS-A, P = .025; HADS-D, P = .030) and Oxford (HADS-A, P = .001; HADS-D, P = .030). However, patients with CRC experienced significant improvement in VAS, Oxford, and HHS/KSS (P < .05) from preoperative to 1 year. Similarly, patients with abnormal HADS showed significant improvement in VAS pain and HHS/KSS (P < .05). CONCLUSION: TJA patients who are anxious, depressed, or pain catastrophizing have inferior preoperative and postoperative pain and function. However, as compared to their preoperative status, clinically significant improvement can be expected following hip/knee arthroplasty.

BACKGROUND: The Fragility Index (FI) is a method for evaluating the robustness of statistically significant findings from randomized controlled trials (RCTs) beyond the P value in trials with dichotomous outcomes. The FI is defined as the number of patients in one arm of a trial that would have to have a different outcome to change the results of the trial from statistically significant to nonsignificant. This review assessed the FI in arthroplasty RCTs. METHODS: A systematic search was conducted in MEDLINE, Embase, and Web of Science for RCTs related to primary total joint arthroplasty (TJA) from 2010 to 2020. Trials with a statistically significant dichotomous primary outcome were included. The FI was calculated using Fisher's exact test to determine how many events would need to be reversed to change a study from statistically significant to nonsignificant. RESULTS: A total of 34 RCTs were included. The median sample size was 103 patients (range 24-791). The median FI was 1 (range 0-45), meaning that reversing the outcome of just one patient in either treatment group of each trial would change it from a significant to a nonsignificant result. CONCLUSION: Hip and knee arthroplasty RCTs with statistically significant dichotomous outcomes in TJA are fragile. The median FI in TJA is lower than the FI in any of the other previously reported orthopedic subspecialties. Fragility is another reason to be cautious when conducting or interpreting small trials, and to continue to strive toward large trials to answer important questions in TJA. LEVEL OF EVIDENCE: Level I.
