RESUMO
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.
RESUMO
PURPOSE: There remains a lack of consensus around autograft selection in anterior cruciate ligament reconstruction (ACLR), though there is a large body of overlapping systematic reviews and meta-analyses. Systematic reviews and their methodological quality were aimed to be further assessed, using a validated tool known as assessing the methodological quality of systematic reviews (AMSTAR-2). METHODS: MEDLINE, Embase and CENTRAL were searched from inception to 23 April 2023 for systematic reviews (with/without meta-analysis) comparing primary ACLR autografts. A final quality rating from AMSTAR-2 was provided for each study ('critically low', 'low', 'moderate' or 'high' quality). Correlational analyses were conducted for ratings in relation to study characteristics. RESULTS: Two thousand five hundred and ninety-eight studies were screened, and 50 studies were ultimately included. Twenty-four studies (48%) were rated as 'critically low', 17 (34%) as 'low', seven (14%) as 'moderate' and two (4%) as 'high' quality. The least followed domains were reporting on sources of funding (1/50 studies), the impact of risk of bias on results of meta-analyses (11/36 studies) and publication bias (17/36 studies). There was a significant increase in the frequency of studies graded as 'moderate' compared to 'low' or 'critically low' quality over time (p = 0.020). CONCLUSION: The methodological quality of systematic reviews comparing autografts in ACLR is low, with many studies being rated lower due to commonly absent aspects of systematic review methodology such as investigating sources of funding and publication bias. More recent studies were generally more likely to be of higher quality. Authors are advised to consult AMSTAR-2 prior to conducting systematic reviews in ACLR. LEVEL OF EVIDENCE: Level IV.

PURPOSE: To evaluate the clinical outcomes in patients undergoing revision anterior cruciate ligament reconstruction (r-ACLR) using hamstring tendon (HT) autografts with those using either quadriceps tendon (QT) or bone-patellar tendon-bone (BPTB) autografts or allografts. METHODS: Three databases were searched on 8 August 2023. The authors adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Revised Assessment of Multiple Systematic Reviews (R-AMSTAR) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, surgical details, patient-reported outcome measures (PROMs), rates of instability, failure and return to sport (RTS) were extracted. RESULTS: Eleven studies comprising 859 patients were included in this review. Five studies compared HT and QT autografts. One study each reported greater IKDC scores (p = 0.04) and Tegner scores (p = 0.04) in the QT group, while one study each reported higher anterior translation (p = 0.04), rates of positive pivot shift (p = 0.03) and rates of failure (p = 0.03) in the HT group. Six studies compared HT and BPTB autografts with one study each reporting greater Lysholm scores (p = 0.02) and less side-to-side anterior laxity (p < 0.01) in the BPTB group. Two studies compared HT autografts with allografts with only one study reporting a faster time to RTS in the HT group than the allograft group (p < 0.001). All other comparisons were not significant. CONCLUSIONS: HT autografts result in either similar or inferior outcomes in r-ACLR when compared to QT or BPTB autograft options. Allografts resulted in similar outcomes to HT autografts apart from greater time to RTS for r-ACLR. LEVEL OF EVIDENCE: Level III.
RESUMO
BACKGROUND: The optimal management of first-time anterior shoulder dislocations (FTASDs) remains controversial. Therefore, the purpose of this study was to assess the efficacy of arthroscopic stabilization surgery for FTASDs through a systematic review and meta-analysis of existing literature. METHODS: MEDLINE, Embase, and Web of Science were searched from inception to December 18, 2022, for single-arm or comparative studies assessing FTASDs managed with arthroscopic stabilization surgery following first-time dislocation. Eligible comparative studies included studies assessing outcomes following immobilization for an FTASD, or arthroscopic stabilization following recurrent dislocations. Eligible levels of evidence were I to IV. Primary outcomes included rates of shoulder redislocations, cumulative shoulder instability, and subsequent shoulder stabilization surgery. RESULTS: Thirty-four studies with 2222 shoulder dislocations were included. Of these, 5 studies (n = 408 shoulders) were randomized trials comparing immobilization to arthroscopic Bankart repair (ABR) after a first dislocation. Another 16 studies were nonrandomized comparative studies assessing arthroscopic Bankart repair following first-time dislocation (ABR-F) to either immobilization (studies = 8, n = 399 shoulders) or arthroscopic Bankart repair following recurrent dislocations (ABR-R) (studies = 8, n = 943 shoulder). Mean follow-up was 59.4 ± 39.2 months across all studies. Cumulative loss to follow-up was 4.7% (range, 0%-32.7%). A composite rate of pooled redislocation, cumulative instability, and reoperations across ABR-F studies was 6.8%, 11.2%, and 6.1%, respectively. Meta-analysis found statistically significant reductions in rates of redislocation (odds ratio [OR] 0.09, 95% confidence interval [CI] 0.04-0.3, P < .001), cumulative instability (OR 0.05, 95% CI 0.03-0.08, P < .001), and subsequent surgery (OR 0.08, 95% CI 0.04-0.15, P < .001) when comparing ABR-F to immobilization. Rates of cumulative instability (OR 0.32, 95% CI 0.22-0.47, P < .001) and subsequent surgery rates (OR 0.27, 95% CI 0.09-0.76, P = .01) were significantly reduced with ABR-F relative to ABR-R, with point estimate of effect favoring ABR-F for shoulder redislocation rates (OR 0.59, 95% CI 0.19-1.83, P = .36). Return to sport rates to preoperative levels or higher were 3.87 times higher following ABR-F compared to immobilization (95% CI 1.57-9.52, P < .001), with limited ABR-R studies reporting this outcome. The median fragility index of the 5 included randomized controlled trials (RCTs) was 2, meaning reversing only 2 outcome events rendered the trials' findings no longer statistically significant. CONCLUSION: Arthroscopic stabilization surgery for FTASDs leads to lower rates of redislocations, cumulative instability, and subsequent stabilization surgery relative to immobilization or arthroscopic stabilization surgery following recurrence. Although a limited number of RCTs have been published on the subject matter to date, the strength of their conclusions is limited by a small sample size and statistically fragile results.

PURPOSE: To compare pronator quadratus preserving (PQ-P) approaches with PQ dissecting (PQ-D) approaches in volar plate fixation of distal radius fractures (DRFs). METHODS: Three databases were searched on March 10th, 2024. The authors adhered to the PRISMA and R-AMSTAR guidelines and Cochrane Handbook for Systematic Reviews. Data on demographics, fracture classifications, patient reported outcome measures (PROMs), range of motion, radiographic parameters, and complications were extracted. RESULTS: Thirteen studies with a total of 1007 fractures were included. Two of three studies reported lower DASH scores in the PQ-P group between 6 weeks and 3 months postoperative, however no studies reported lower scores in the PQ-P group after 3 months. Three of three studies reported significantly lower VAS scores at 6 weeks postoperative, however no studies reported significant differences after 6 months. Only one of six studies reported significantly greater flexion, extension, and pronation in the PQ-P group. One of four studies reported greater radial deviation in the PQ-P group, while there were no differences in supination or ulnar deviation. One of ten and one of six studies reported greater volar tilt and ulnar variance or radial length, respectively, in the PQ-P group. CONCLUSION: There is not sufficient evidence supporting the utility of PQ-P approaches over conventional PQ-D approaches for volar plate fixation of DRFs, especially at long-term follow-ups (3+ months). There may be short term benefits with PQ-P approaches, specifically with regards to PROMs in the short-term (< 6 weeks), however there is limited high-quality evidence supporting these findings. LEVEL OF EVIDENCE: Level III.

PURPOSE: To identify and assess the clinical impact of randomised controlled trials (RCTs) assessing the surgical management of femoroacetabular impingement syndrome (FAIS) through a citation analysis. METHODS: MEDLINE, EMBASE and CENTRAL were searched from inception to April 22, 2023 for RCTs assessing the surgical management of FAIS. Study characteristics were directly abstracted from included trials and citation metrics were obtained from the Clarivate Web of Knowledge database on May 19, 2023. The continuous fragility index (CFI) was calculated for eligible outcomes. Univariate regression models were used to explore correlations between total citations per year and various study characteristics. RESULTS: Ten studies comprising one thousand two hundred ninetypatients were eligible for analysis. Studies were published from 2013 to 2023. Eight countries were represented across various trials with 91% being either North American or European. The mean journal impact factor of published studies was 39.684 (median 2.982; range 1.31-202.73). The mean citation density was 14.17 (range 0.33-48.67). The median CFI was 4.8 (range 1-32.2). Correlation analysis demonstrated strong and statistically significant correlations to study sample size (R = 0.75, p = 0.012), journal impact factor (R = 0.80, p = 0.006) and continuous fragility index (R = 0.95, p = 0.015). CONCLUSION: Trials assessing the surgical management of FAIS present with a wide range of clinical uptake based on citation density and are published in journals of broadly variable impact factor. Despite promising citation metrics, high-quality evidence on arthroscopy for FAIS is limited to the United States and Europe with an unclear international impact. Future knowledge translation efforts are warranted to maximise the international uptake of evidence regarding arthroscopic management of FAIS. LEVEL OF EVIDENCE: I.

PURPOSE: To evaluate the clinical outcomes of primary or revision ACL reconstruction (ACLR) after contralateral hamstring autografts versus ipsilateral hamstring autograft harvest. METHODS: Three databases (MEDLINE, PubMed and EMBASE) were searched from inception to April 27th, 2023 for studies investigating contralateral hamstring autografts in primary or revision ACLR. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, strength measures, patient-reported outcome measures (PROMs), and rates of positive Lachman test, positive pivot-shift test and graft rupture were extracted. PROMs included Lysholm, International Knee Documentation Committee (IKDC) and Tegner scores. RESULTS: Nine studies comprising 371 patients were included in this review. In primary ACLR, there were no significant differences between contralateral and ipsilateral groups in isokinetic hamstring torque in the non-ACLR limb or isokinetic quadriceps torque in both limbs when tested at 60, 90, 120 or 180 degrees/second. Isokinetic hamstring torque in the non-ACLR limb was significantly weaker in the contralateral group at six months for primary ACLR; however, these deficits did not persist. There were no significant differences in postoperative median Tegner scores and Lysholm scores between contralateral and ipsilateral groups in primary ACLR. There were no significant differences in postoperative median Tegner, mean Lysholm and IKDC scores between groups in revision ACLR. There were no significant differences in positive Lachman, positive pivot-shift and rupture rates in primary ACLR between groups. Rates of positive Lachman and pivot-shift were slightly higher in the contralateral than ipsilateral group for revision ACLR. CONCLUSION: Contralateral hamstring autografts results in comparable muscle strength to ipsilateral hamstring autografts, with the exception of weaker hamstring strengths in the early postoperative period. Patient-reported outcome measures were similar between the two groups across both primary and revision ACLR, with rates of instability and failure being similar between groups for primary ACLR. Contralateral hamstring grafts do not provide additional benefit when compared to ipsilateral options for either primary or revision ACLR, and should be used only in select circumstances including insufficient ipsilateral hamstring grafts or situations where quadriceps or patella autografts are not optimal. LEVEL OF EVIDENCE: Level IV.

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: Proximal humerus fractures are the second-most common fragility fracture in older adults. Although reverse total shoulder arthroplasty (RTSA) is a promising treatment strategy for proximal humerus fractures with favorable clinical and quality of life outcomes, it is associated with much higher, and possibly prohibitive, upfront costs relative to nonoperative treatment and other surgical alternatives. QUESTIONS/PURPOSES: (1) What is the cost-effectiveness of open reduction internal fixation (ORIF), hemiarthroplasty, and RTSA compared with the nonoperative treatment of complex proximal humerus fractures in adults older than 65 years from the perspective of a single-payer Canadian healthcare system? (2) Which factors, if any, affect the cost-effectiveness of ORIF, hemiarthroplasty, and RTSA compared with nonoperative treatment of proximal humerus fractures including quality of life outcomes, cost, and complication rates after each treatment? METHODS: This cost-utility analysis compared RTSA, hemiarthroplasty, and ORIF with the nonoperative management of complex proximal humerus fractures in adults older than 65 years over a lifetime time horizon from the perspective of a single-payer healthcare system. Short-term and intermediate-term complications in the 2-year postoperative period were modeled using a decision tree, with long-term outcomes estimated through a Markov model. The model was initiated with a cohort of 75-year-old patients who had a diagnosis of a comminuted (three- or four-part) proximal humerus fractures; 90% of the patients were women. The mean age and gender composition of the model's cohort was based on a systematic review conducted as part of this analysis. Patients were managed nonoperatively or surgically with either ORIF, hemiarthroplasty, or RTSA. The three initial surgical treatment options of ORIF, hemiarthroplasty, and RTSA resulted in uncomplicated healing or the development of a complication that would result in a subsequent surgical intervention. The model reflects the complications that result in repeat surgery and that are assumed to have the greatest impact on clinical outcomes and costs. Transition probabilities and health utilities were derived from published sources, with costs (2020 CAD) sourced from regional costing databases. The primary outcome was the incremental cost-utility ratio, which was calculated using expected quality-adjusted life years (QALYs) gained and costs. Sensitivity analyses were conducted to explore the impact of changing key model parameters. RESULTS: Based on both pairwise and sequential analysis, RTSA was found to be the most cost-effective strategy for managing complex proximal humerus fractures in adults older than 65 years. Compared with nonoperative management, the pairwise incremental cost-utility ratios of hemiarthroplasty and RTSA were CAD 25,759/QALY and CAD 7476/QALY, respectively. ORIF was dominated by nonoperative management, meaning that it was both more costly and less effective. Sequential analysis, wherein interventions are compared from least to most expensive in a pairwise manner, demonstrated ORIF to be dominated by hemiarthroplasty, and hemiarthroplasty to be extendedly dominated by RTSA. Further, at a willingness-to-pay threshold of CAD 50,000/QALY, RTSA had 66% probability of being the most cost-effective treatment option. The results were sensitive to changes in the parameters for the probability of revision RTSA after RTSA, the treatment cost of RTSA, and the health utilities associated with the well state for all treatment options except ORIF, although none of these changes were found to be clinically realistic based on the existing evidence. CONCLUSION: Based on this economic analysis, RTSA is the preferred treatment strategy for complex proximal humerus fractures in adults older than 65 years, despite high upfront costs. Based on the evidence to date, it is unlikely that the parameters this model was sensitive to would change to the degree necessary to alter the model's outcome. A major strength of this model is that it reflects the most recent randomized controlled trials evaluating the management of this condition. Therefore, clinicians should feel confident recommending RTSA for the management of proximal humerus fractures in adults older than 65 years, and they are encouraged to advocate for this intervention as being a cost-effective practice, especially in publicly funded healthcare systems wherein resource stewardship is a core principle. Future high-quality trials should continue to collect both clinical and quality of life outcomes using validated tools such as the EuroQOL-5D to reduce parameter uncertainty and support decision makers in understanding relevant interventions' value for money. LEVEL OF EVIDENCE: Level III, economic and decision analysis.

PURPOSE: To assess the performance of the quadriceps tendon (QT) autograft in pediatric anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic search of MEDLINE, PubMed, and EMBASE was conducted on March 1, 2021. Studies of all levels of evidence reporting outcomes and/or complications after QT autograft ACLR in pediatric patients (≤ 18 years old) were eligible for inclusion. Study demographics, patient demographics, reported outcomes, and complications were abstracted. Screening and data abstraction were designed in accordance with PRISMA and R-AMSTAR guidelines. Descriptive statistics were presented when applicable, with data for heterogeneous outcomes presented in narrative summary fashion. RESULTS: A total of 14 studies examining 596 patients (46.3% female), mean age 15.4 years, were included in this systematic review. Mean postoperative Lysholm scores ranged from 94.0 to 99.5. Mean postoperative IKDC subjective scores ranged from 75.9 to 94.0. Limb symmetry index ranged from 96.8 ± 10.4 to 100.4 ± 7.6% across multiple hop tests. Return to sports (RTS) rates ranged from 88.9 to 91.7%. Eleven studies reported postoperative complications, whereby 16 patients (4.8%) experienced contralateral complications and injuries. Forty-six patients (9.4%) experienced ipsilateral complications, including ten graft failures (2.5%) and two growth disturbances (0.6%). CONCLUSIONS: QT autograft ACLR in the pediatric population retains the potential of regaining a preinjury level of knee stability, and yields promising postoperative function and rates of RTS, yielding comparable outcomes relative to HT autograft and the reference-standard BPTB ACLR that have previously been described in the literature. Moreover, use of the QT autograft is associated with low rates of postoperative complications, including graft failure and growth disturbances in this active and high-risk patient population in observational studies to date. Therefore, clinical equipoise exists to further appraise the influence of QT autograft on postoperative outcomes compared to aforementioned autograft options in a randomized control trial fashion. LEVEL OF EVIDENCE: IV.

PURPOSE: The aim of this systematic review was to evaluate the impact of bone grafting of patellar defects on reported anterior knee morbidity and subjective outcomes after bone-patellar tendon-bone autograft reconstruction of the anterior cruciate ligament. METHODS: A systematic electronic search of MEDLINE, Embase, Web of Science, and the Cochrane Library was carried out. All English-language prospective randomized clinical trials published from January 1, 2000, to July 24, 2020, were eligible for inclusion. All studies addressing patellar defect grafting were eligible for inclusion regardless of the timing of surgery, graft type, surgical technique, or rehabilitation protocol. RESULTS: A total of 39 studies with 1,955 patients were included for analysis. There were 796 patients in the no patellar grafting (NPG) group, with a mean age range of 22.7 to 33.0 years, and 1,159 patients in the patellar grafting (PG) group, with a mean age range of 17.8 to 34.7 years. The visual analog scale pain score ranged from 1.2 to 5.1 in the NPG group compared with 0.3 to 3.7 in the PG group. The proportion of patients with anterior knee pain ranged from 19% to 81% in the NPG group and from 15% to 32% in the PG group. Moderate to severe kneeling pain was reported in 22% to 57% of patients in the NPG group and 10% of those in the PG group. The percentage of patients with at least 3° of extension loss ranged from 4% to 43% in the NPG group and from 2% to 11% in the PG group. CONCLUSIONS: PG favors decreased anterior knee pain, kneeling pain, and extension loss compared with non-grafted defects; however, the functional outcomes are comparable. Owing to the heterogeneity in reporting, statistical conclusions could not be drawn. LEVEL OF EVIDENCE: Level II, systematic review of Level I and II studies.

OBJECTIVE: The aim of this study was to explore the efficacy of current bariatric perioperative measures at reducing emergency department (ED) visits following bariatric surgery in the state of Michigan. SUMMARY OF BACKGROUND DATA: Many ED visits following bariatric surgery do not result in readmission and may be preventable. Little research exists evaluating the efficacy of perioperative measures aimed at reducing ED visits in this population. Therefore, understanding the driving factors behind these preventable ED visits may be a fruitful approach to prevention. Furthermore, evaluating the efficacy of current perioperative measures may shed light on how to achieve meaningful reductions in ED visits. METHODS: We studied 48,035 eligible bariatric surgery patients across 37 Michigan Bariatric Surgical Collaborative (MBSC) sites between January 2012 and October 2015. Hospitals were ranked according to their risk- and reliability-adjusted ED visit rates. For hospitals in each ED visit rate tercile, several patient, surgery, and hospital summary characteristics were compared. We then studied whether a hospital's compliance with specific perioperative measures was significantly associated with reduced ED visit rates. RESULTS: Only 3 of the 30 surgery, hospital, and patient summary characteristics studied were significant predictors of a hospital's ED visit rate: rate of sleeve gastrectomies, rate of readmissions, and rate of venous thromboembolism complications (P = 0.04, P = 0.0065, and P = 0.0047, respectively). Also, a hospital's compliance with the perioperative measures evaluated was not a significant predictor of ED visit rates (P = 0.12). CONCLUSIONS: Current practices aimed at reducing ED visits appear to be ineffective. Due to heterogeneity in patient populations and local infrastructure, a more tailored approach to ED visit reduction may be more successful.

BACKGROUND: Evidence-based care relies on robust research. The fragility index (FI) is used to assess the robustness of statistically significant findings in randomized controlled trials (RCTs). While the traditional FI is limited to dichotomous outcomes, a novel tool, the continuous fragility index (CFI), allows for the assessment of the robustness of continuous outcomes. PURPOSE: To calculate the CFI of statistically significant continuous outcomes in RCTs evaluating interventions for managing anterior shoulder instability (ASI). STUDY DESIGN: Meta-analysis; Level of evidence, 2. METHODS: A search was conducted across the MEDLINE, Embase, and CENTRAL databases for RCTs assessing management strategies for ASI from inception to October 6, 2022. Studies that reported a statistically significant difference between study groups in ≥1 continuous outcome were included. The CFI was calculated and applied to all available RCTs reporting interventions for ASI. Multivariable linear regression was performed between the CFI and various study characteristics as predictors. RESULTS: There were 27 RCTs, with a total of 1846 shoulders, included. The median sample size was 61 shoulders (IQR, 43). The median CFI across 27 RCTs was 8.2 (IQR, 17.2; 95% CI, 3.6-15.4). The median CFI was 7.9 (IQR, 21; 95% CI, 1-22) for 11 studies comparing surgical methods, 22.6 (IQR, 16; 95% CI, 8.2-30.4) for 6 studies comparing nonsurgical reduction interventions, 2.8 for 3 studies comparing immobilization methods, and 2.4 for 3 studies comparing surgical versus nonsurgical interventions. Significantly, 22 of 57 included outcomes (38.6%) from studies with completed follow-up data had a loss to follow-up exceeding their CFI. Multivariable regression demonstrated that there was a statistically significant positive correlation between a trial's sample size and the CFI of its outcomes (r = 0.23 [95% CI, 0.13-0.33]; P < .001). CONCLUSION: More than a third of continuous outcomes in ASI trials had a CFI less than the reported loss to follow-up. This carries the significant risk of reversing trial findings and should be considered when evaluating available RCT data. We recommend including the FI, CFI, and loss to follow-up in the abstracts of future RCTs.
RESUMO
Background: There is still controversy surrounding the routine use of vancomycin locally in primary orthopaedic surgery procedures. Therefore, the aim of this review is to assess how local vancomycin impacts the rates and microbiology of surgical site infections. Methods: A systematic electronic search of MEDLINE, EMBASE, and Web of Science was carried out for all comparative studies comparing locally applied vancomycin to control for primary orthopaedic surgery procedures published before August 14, 2022. Results: A total of 61 studies with 65,671 patients were included for analysis. Forty-six studies used vancomycin powder, 12 studies with grafts soaked in vancomycin, two studies used vancomycin irrigation, and one study administered vancomycin interosseously. There were 15 studies (of 26) in spine surgery, five (of 14) in arthroplasty, ten (of 11) in sports medicine, and two (of five) in trauma surgery that found statistically significant decreases in overall infection rates when applying local vancomycin. Only one study (in spine surgery) found significant increases in infection rates with local vancomycin application. For spine surgery, local vancomycin application had the greatest proportion of gram-negative bacteria (40.7%) isolated compared to S. aureus (42.4%) in controls. In arthroplasty and trauma surgery, there were increases in the proportions of gram-negative bacteria when vancomycin was added. There were no reported systemic adverse reactions associated with local vancomycin use in any of the studies. Conclusion: Applying local vancomycin during primary orthopaedic surgery procedures may reduce the rates of infections in multiple different orthopaedic specialties, particularly in spine surgery and sports medicine. However, careful consideration should be applied when administering local vancomycin during specific orthopaedic procedures given the heterogeneity of included studies and breadth of surgeries included in this review. Level of evidence: Level III. A systematic review of level I - III studies.
RESUMO
Purpose: There is a lack of scientific consensus on the best arthroplasty implant option for proximal interphalangeal joint (PIPJ) arthritis, due to diversity in outcome reporting and measurement methods. The development of a standardized core outcome set (COS) and standard outcome measures could mitigate this issue. This study catalogs the reported outcomes and outcome measures found in PIPJ arthroplasty studies, which can be used in the first step of developing a COS. Methods: A database search of MEDLINE, EMBASE, and Web of Science (January 1, 2010, to March 10, 2021) was performed to retrieve studies that reported outcomes of the 3 most common primary PIPJ arthroplasty implants: silicone, pyrocarbon, and metal-polyethylene. The primary objectives of this study include reported outcomes and outcome measures. Secondary objectives include clinimetric properties of outcome measures, study design, and implant types. Results: Fifty articles met inclusion criteria. Of the included studies, 41 (82%) were case series, 8 (16%) were cohort studies, and 1 (2%) was a randomized control trial. Thirty-three unique outcomes were identified. Fifteen (46%) outcomes were clinician-reported and 26 (79%) were patient-reported. Eighteen unique outcome measures were identified. Of the outcome measures, 15 (83%) were patient-reported, 1 (6%) was clinician-reported, and 2 (11%) were reported by both patients and clinicians. Conclusions: Substantial heterogeneity was found in reported outcomes and outcome measures across studies evaluating PIPJ arthroplasty, impeding knowledge translation. The development of a COS for PIPJ arthroplasty is necessary to help compare and pool data across studies, and advance scientific knowledge.
Objectif: Il manque de consensus scientifique sur la meilleure option d'arthroplastie pour l'arthrite de l'articulation interphalangienne proximale (IPP) en raison de la diversité des résultats décrits et des méthodes de mesure. L'élaboration d'un ensemble standardisé de résultats de base et de mesures standardisées des résultats pourrait contribuer à limiter ce problème. Cette étude dresse un catalogue des résultats rapportés et des mesures de résultats trouvés dans les études sur l'arthroplastie des IPP; celui-ci peut servir de première étape à l'élaboration d'un ensemble standardisé de résultats de base. Méthodes: Une recherche a été menée dans les bases de données MEDLINE, EMBASE et Web of Science sur la période du 1er janvier 2010 au 10 mars 2021 pour extraire les études qui rapportaient des résultats avec les 3 implants pour arthroplastie des IPP les plus souvent utilisés : silicone, pyrocarbone et métal-polyéthylène. Les objectifs principaux de cette étude incluent les résultats rapportés et les mesures des résultats. Les objectifs secondaires sont, notamment, les propriétés clinimétriques des mesures des résultats, la conception des études et les types d'implants. Résultats: Cinquante articles satisfaisaient les critères d'inclusion. Parmi les études incluses, 41 (82%) étaient des séries de cas, 8 (16%) étaient des études de cohortes et 1 (2%) était un essai randomisé. Trente-trois résultats uniques ont été identifiés. Quinze résultats (46%) étaient rapportés par le clinicien et 26 (79%) ont été déclarés par les patients. Dix-huit mesures uniques de résultats ont été identifiées. Parmi les mesures de résultats, 15 (83%) ont été déclarées par les patients, 1 (6%) a été déclarée par un clinicien et 2 (11%) ont été déclarées à la fois par les patients et les cliniciens. Conclusions: Une hétérogénéité importante a été constatée dans les résultats rapportés et dans les mesures de résultats dans les études évaluant l'arthroplastie des IPP, entravant leur traduction en connaissances utiles. L'élaboration d'un ensemble standardisé de résultats de base s pour les IPP est nécessaire pour comparer et regrouper les données entre les études et donc pour faire avancer les connaissances scientifiques.
RESUMO
OBJECTIVES: To synthesize all-cause complications and reoperations data, and secondary clinical, functional, and radiographic outcomes after the management of very distal ulna fractures (VDUFs) either nonoperatively or operatively. DATA SOURCES: MEDLINE, Embase, and Web of Science were searched for English-language articles from inception to February 17, 2022. STUDY SELECTION: Studies reporting the nonoperative or operative management of VDUFs were eligible for inclusion. VDUFs were defined as either being Q2-Q5 distal ulna fractures using the OTA/AO Comprehensive Classification of Fractures for distal ulna fractures associated with distal radius fractures or being amenable to characterization by the classification system for ulnar head, neck and metaphyseal fractures by Biyani et al. DATA EXTRACTION: Two reviewers independently extracted data from included studies. Study validity was assessed using the methodological index for nonrandomized studies. DATA SYNTHESIS: Seventeen studies (512 VDUFs) were included for analysis. There were 209, 237, and 66 fractures in the nonoperative, open reduction internal fixation (ORIF), and distal ulna resection groups, respectively. Descriptive statistics including weighted mean values, standard deviations, and 95% confidence intervals were calculated. CONCLUSIONS: The treatment of VDUFs with nonoperative management, ORIF, or distal ulna resection may all be acceptable treatment options in specific patient populations. Nonoperative management of VDUFs is a promising treatment strategy even for complex fracture patterns in patients 65 years of age or older. Despite higher reoperation rates, ORIF may be considered for the younger, high-demand patient. Distal ulna resection presents with very favorable functional outcomes in patients 65 years of age or older presenting with a complex VDUF with the lowest reoperation rate across all groups. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Background: There is currently a scarcity of information and consensus for transportal (arthroscopic or fluoroscopic) joint preparation during tibiotalocalcaneal (TTC) fusion, and therefore this review aims to summarize the available techniques and to evaluate the outcomes after this procedure. Methods: A systematic electronic search of MEDLINE, EMBASE, and Web of Science was performed for all English-language studies published from their inception to April 4, 2022. All articles addressing arthroscopy in TTC nailing were eligible for inclusion. The PRISMA Checklist guided the reporting and data abstraction. Descriptive statistics are presented. Result: A total of 5 studies with 65 patients were included for analysis. All studies used arthroscopic portals for tibiotalar and subtalar joint preparation (in 4 studies) prior to TTC nailing, with 4 studies using an arthroscope and 1 study using fluoroscopy. The overall major complication rate was 13.8%; however, there was only 1 instance of deep wound infection (1.5%) and 4 instances of surgical site infections (6.2%). Full fusion was achieved in 86% of patients with an average time to fusion of 12.9 weeks. The mean American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score preoperatively was 34.0 and postoperatively was 70.5. Conclusion: Although limited by the number of studies, transportal joint preparation during TTC nail ankle fusion is associated with good rates of complications and successful fusion. Level of Evidence: Level III, systematic review of Level III-IV studies.
RESUMO
IMPORTANCE: A paucity of clinical evidence surrounds the effect of the knee flexion angle during tibial fixation of the graft during anterior cruciate ligament (ACL) reconstruction. While biomechanical studies have recently sought to revive this area of study in both single- and double-bundle graft populations, they have done so using variants of the hamstring graft. This does not shed light on the optimal fixation of other autograft options, namely, the quadriceps tendon (QT) autograft. OBJECTIVES: To determine the effect of the knee flexion angle during tibial graft fixation on functional and clinical outcomes following ACL reconstruction using single-bundle QT autograft, inclusive of both soft-tissue and bone-plug graft types. EVIDENCE REVIEW: An electronic search of MEDLINE, EMBASE, Web of Science, and the Cochrane Library was carried out from database inception to June 2020. Following study screening, patient demographics and fixation technique as well as both subjective and objective clinical outcomes were abstracted. Studies were divided based on the knee flexion angle during tibial fixation of the graft. The low knee flexion angle (L-KFA) group included patients with a tibial fixation angle of < 30° of flexion, and the high knee flexion (H-KFA) group included those with a tibial fixation of exactly 30° of flexion. The data were qualitatively synthesized due to significant heterogeneity across the included studies. FINDINGS: Sixteen studies (1,169 patients) were included for analysis. There were 675 patients in the L-KFA group (mean age range, 18.7-34.5 years) and 494 patients in the H-KFA group (mean age range, of 23.2-32.1 years). Both groups yielded statistically significant improvements from preoperative to postoperative scores across several functional and clinical outcomes. Return to pre-injury activity levels ranged from 64% to 81% in L-KFA studies and from 73.3% to 86.7% in H-KFA studies. All-cause graft failure rates ranged from 1.4% to 4.3% in L-FKA studies and from 0%-10.7% in H-KFA studies. CONCLUSION: Both low- and high-knee flexion angles during tibial graft fixation produce improved postoperative clinical and functional outcomes with comparable outcomes across groups. There is inconclusive evidence to recommend the ideal knee flexion angle for graft fixation in primary ACLR. LEVEL OF EVIDENCE: Level IV.

Background: Distal femoral varus osteotomy (DFVO) is an effective surgical intervention for the management of symptomatic valgus malalignment of the knee. Because it preserves the native knee joint and its ligamentous stability, DFVO is preferred to total knee arthroplasty (TKA) in the young, active population. Purpose: We sought to assess return to work (RTW) and return to sport (RTS) rates following DFVO for valgus malalignment of the knee. Methods: For this systematic review, we searched EMBASE, MEDLINE, and Web of Science from inception through December 31, 2020. English language studies of all levels of evidence explicitly reporting on RTS and RTW rates following DFVO for valgus malalignment of the knee were eligible for inclusion. Results: Seven studies and 127 patients were included in our analysis. Mean age was 32.4 ± 8.8 years with men comprising 46.7% ± 22.3% of study populations. The mean RTS rate was 87.2% ± 10.7%, with a return to preoperative activity levels rate of 65.4% ± 26.8%. The mean RTW rate was 81.8% ± 23.3%, with a return to preoperative activity levels of 72.8% ± 18.1%. The mean reoperation rate was 35.6% ± 18.8% within a mean follow-up period of 5.5 ± 1.9 years. Conclusions: This systematic review of low-level studies found DFVO to be a safe and effective procedure for the management of genu valgum in young, active populations, with most patients returning to sport and/or work, although not all at their preoperative activity levels. A paucity of data surrounds RTS and RTW rates following DFVO. Future studies should explicitly report both return to activity rates and whether patients returned to their preoperative activity levels.
RESUMO
Objective: To synthesize the best evidence surrounding the efficacy of cannabinoids for acute pain in the clinical setting based on subjective pain scores and observed adverse effects. Design: Systematic review with meta-analysis. Data Sources: PubMed, Embase, Cochrane Databases, and Google Scholar. Eligibility Criteria: English-language randomized-controlled clinical trials comparing cannabinoids with placebo in patients with acute pain. Data Extraction and Synthesis: Study quality was assessed using the Cochrane risk of bias tool. All stages were conducted independently by a team of three reviewers. Data were pooled through meta-analysis and stratified by route of administration. Primary Outcomes and Measures: Patient-reported pain and adverse events (AEs). Results: Six trials (678 participants) were included examining oral (5 trials) and intramuscular (1 trial) cannabinoids. Overall, there was a small but statistically significant treatment effect favoring the use of cannabinoids over placebo (-0.90, 95% confidence interval [CI] -1.69 to -0.1, i 2=65%, p=0.03). When stratified by route of administration, intramuscular cannabinoids were found to have a significant reduction in pain relative to placebo (-2.98, 95% CI -4.09 to -1.87, i 2=0%, p<0.0001). No difference in effect was observed between oral cannabinoids and placebo (-0.21, 95% CI -0.64 to 0.22, i 2=3%, p=0.34). Serious AEs were rare, and similar across the cannabinoid (14/374, 3.7%) and placebo groups (8/304, 2.6%). Conclusions: There is low-quality evidence indicating that cannabinoids may be a safe alternative for a small but significant reduction in subjective pain score when treating acute pain, with intramuscular administration resulting in a greater reduction relative to oral. Higher quality, long-term randomized-controlled trials examining whether there may be a role for cannabinoids in treating acute pain are required.
