Risk factors for prolonged opioid consumption following hip arthroscopy: A secondary analysis of the Femoroacetabular Impingement RandomiSed controlled Trial and embedded cohort study.

PURPOSE: The purpose of the study was to identify prognostic risk factors for prolonged opioid use at 2 and 6 weeks after hip arthroscopy using data from the Femoroacetabular Impingement RandomiSed controlled Trial and its external validation cohort study. METHODS: Opioids were prescribed for postoperative pain management at the surgeon's discretion, with a majority being prescribed a combination of oxycodone and paracetamol (5/325 mg). Prolonged opioid use was defined as the ongoing use of any dosage of opioids reported at either 2 or 6 weeks after surgery to treat femoroacetabular impingement, as recorded in the patient's study medication log. Multivariable logistic regressions were performed to evaluate patient and surgical characteristics, such as preoperative opioid use, type of surgical procedure and intraoperative cartilage state that may be associated with prolonged opioid use at either 2 and 6 weeks postoperatively. RESULTS: A total of 265 and 231 patients were included for analysis at 2 and 6 weeks postoperatively, respectively. The median age of participants was 35 years (interquartile range [IQR]: 27-42) and 33% were female. At 2 weeks postoperatively, female sex (odds ratio [OR]: 2.56; 95% confidence interval: [CI] 1.34-4.98, p = 0.005), higher body mass index (BMI) (OR: 1.10; 95% CI: 1.02-1.18, p = 0.009), active tobacco use (OR: 4.06; 95% CI: 1.90-8.97, p < 0.001), preoperative opioid use (OR: 10.1; 95% CI: 3.25-39.1, p < 0.001) and an Outerbridge classification of ≥3 (OR: 2.33; 95% CI: 1.25-4.43, p = 0.009) were significantly associated with prolonged opioid use. At 6 weeks postoperatively, only preoperative opioid use was significantly associated with prolonged opioid consumption (OR: 10.6; 95% CI: 3.60-32.6, p < 0.001). CONCLUSION: Preoperative opioid use was significantly associated with continued opioid use at 2 and 6 weeks postoperatively. Specific patient factors including female sex, higher BMI, active tobacco use and more severe cartilage damage should be considered in developing targeted strategies to limit opioid use after surgery. LEVEL OF EVIDENCE: Level III.

Labral repair, reconstruction, and augmentation improve postoperative outcomes in patients with irreparable or hypoplastic labra: A systematic review.

PURPOSE: To review the postoperative outcomes of arthroscopic surgical options in treating irreparable and hypoplastic labrum of the hip. METHODS: Three online databases (PubMed, MEDLINE, and EMBASE) were searched from database inception to June 27, 2023 to identify literature on treatment strategies for hypoplastic/irreparable acetabular labrum. Data pertaining to classification of irreparable tears or labral hypoplasia, indication for surgery, description of treatment, radiographic findings, and clinical outcomes were recorded and described. The methodological quality of included studies was assessed by the Methodological Index for Non-Randomized Studies (MINORS) criteria. RESULTS: Seven level IV case series, eleven level III retrospective cohort studies, and two level II prospective cohort studies comprising 1937 patients were included for analysis. Studies were divided into an irreparable labral group comprising 1002 patients and a hypoplastic labral group comprising 935 patients. Treatments included repair, augmentation, or reconstruction. In the irreparable group, 12 studies recorded improvement of modified Harris Hip Score (mHHS) with preoperative scores ranging from 50.3 to 67.3 and postoperative scores ranging from 76.2 to 95.0. The rate of conversion to total hip arthroplasty (THA) and rate of revision arthroscopy were 6.6% and 5.9%, respectively across all studies. In the hypoplastic group, two studies that focused on repair noted no statistical difference in mHHS for repair in hypoplastic labrum vs repair in non-hypoplastic labrum. One study showed that there was a difference in post-operative mHHS for labral repair for hypoplastic vs non-hypoplastic labrum, with repair in non-hypoplastic labrum showing superior mHHS (p â€‹< â€‹0.001). CONCLUSION: The findings of this review suggest that treatment of irreparable labra with reconstruction or augmentation results in improved patient-reported outcome measures (PROMs). For the hypoplastic labrum, primary repair also results in improvement in PROMs. Future studies focusing on the hypoplastic labra alone with an appropriate control group, rather than irreparable labral tears, are needed to properly assess patient outcomes and guide surgical indications.

Return-to-Sport Rates After Hip Arthroscopy for Femoroacetabular Impingement Syndrome in Flexibility Sports Athletes: A Systematic Review.

CONTEXT: Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain in young adults. Flexibility athletes represent an interesting subset due to the extreme range of motion requirements of their sport. OBJECTIVE: The objective of this review was to provide a summary of the outcomes of hip arthroscopy for FAIS in patients who participate in flexibility sports. DATA SOURCES: Three online databases (Medline, Embase, and PubMed) were searched from database inception (1946, 1974, and 1966, respectively) to January 10, 2023. STUDY SELECTION: Studies were screened for literature addressing surgical outcomes for flexibility athletes undergoing hip arthroscopy for FAIS. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Various patient-reported outcomes that evaluated the efficacy of hip arthroscopy in this patient population were abstracted and presented in descriptive and analytical format. Abstraction was performed by 2 reviewers. RESULTS: Overall, a total of 8 Level 3 or 4 studies and 295 patients (312 hips) were included in this review. The pooled standardized mean differences for the Visual Analog Scale for pain score, Modified Harris Hip Score, Hip Outcome Score - Activity of Daily Living scale, and Hip Outcome Score - Sport-Specific Subscale all demonstrated significant improvement after undergoing arthroscopy for FAIS between 12 and 116 months (N = 175, -1.97, 95% CI -2.5 to -1.4, P < 0.01, I2 = 76%; N = 211, 1.82, 95% CI 1.49 to 2.16, P < 0.01, I2 = 52%; N = 164, 1.75, 95% CI 1.42 to 2.05, P < 0.01, I2 = 28%; N = 211, 1.71, 95% CI 1.38 to 2.04, P < 0.01, I2 = 52%, respectively). Across 289 patients, 75.6% to 98% returned to sport at a similar or higher level than presurgery. CONCLUSION: This review demonstrates a trend of improvement in patient-reported pain, function, quality of life, and return to sport at a minimum of 12 months among flexibility athletes after hip arthroscopy to treat FAIS.

The Radiographic Femoroepiphyseal Acetabular Roof Index Is a Reliable and Reproducible Diagnostic Tool in Patients Undergoing Hip-Preservation Surgery: A Systematic Review.

PURPOSE: To assess the utility of the femoroepiphyseal acetabular roof (FEAR) index as a diagnostic tool in hip-preservation surgery. METHODS: MEDLINE, EMBASE, and PubMed were searched from database inception until May 2022 for literature addressing the utility of the FEAR index in patients undergoing hip-preservation surgery, and the results are presented descriptively. RESULTS: Overall, there were a total of 11 studies comprising 1,458 patients included in this review. The intraobserver agreement for the FEAR index was reported by 3 of 11 studies (intraclass correlation coefficient range = 0.86-0.99), whereas the interobserver agreement was reported by 8 of 11 studies (intraclass correlation coefficient range = 0.776-1). Among the 5 studies that differentiated between hip instability and hip impingement, the mean FEAR index in 319 patients in the instability group ranged from 3.01 to 13.3°, whereas the mean FEAR index in 239 patients in the impingement group ranged from -10 to -0.77° and the mean FEAR index in 105 patients in the control group ranged from -13 to -7.7°. Three studies defined a specific cutoff value for the FEAR index, with 1 study defining a cutoff value of 5°, which correctly predicted treatment decision between periacetabular osteotomy versus osteochondroplasty 79% of the time with an AUC of 0.89, whereas another defined a cutoff of 2°, which correctly predicted treatment 90% of the time and the last study set a threshold of 3°, which provided an AUC of 0.86 for correctly predicting treatment decision. CONCLUSIONS: This review demonstrates that the FEAR index has a high agreement and consistent application, making it a useful diagnostic tool in hip-preservation surgery particularly in patients with borderline dysplastic hips. However, given the variability in FEAR index cutoff values across studies, there is no absolute consensus value that dictates treatment decision. LEVEL OF EVIDENCE: Level IV; Systematic Review of Level II-IV studies.

From Protocol to Definitive Study-The State of Randomized Controlled Trial Evidence in Sports Medicine Research: A Systematic Review and Survey Study.

OBJECTIVE: To evaluate the progression, quality, and challenges associated with conducting and publishing randomized controlled trials (RCTs) in sports medicine. DESIGN: Systematic review and survey. SETTING: MEDLINE and Embase were searched for all publications before September 17, 2021. A targeted search of clinicaltrials.gov , BMC Musculoskeletal Disorders, PubMed, and Google Scholar were also conducted. The survey was administered to authors using REDCap. PARTICIPANTS: Where the systematic search revealed no corresponding published definitive trial, authors of the published pilots were surveyed. INTERVENTIONS: Survey assessing limitations to definitive trials. MAIN OUTCOME MEASURES: Protocol/method articles, pilot articles, and relevant clinical trial registry records with corresponding definitive trials were pooled. RESULTS: Our literature search yielded 27 006 studies; of which, we included 208 studies (60 (28.8%) pilot RCTs, 84 (40.4%) protocol/method articles, and 64 (30.8%) trial registry records). From these, 44 corresponding definitive RCTs were identified. Pilot study and definitive RCT methodological quality increased on average most significantly during the duration of this review (30.6% and 8.2%). Of the 176 authors surveyed, 59 (33.5%) responded; 24.6% (14/57) stated that they completed an unpublished definitive trial, while 52.6% (30/57) reported having one underway. CONCLUSIONS: The quality and number of RCT publications within the field of sports medicine has been increasing since 1999. The number of sports medicine-related protocol and pilot articles preceding a definitive trial publication showed a sharp increase over the past 10 years, although only 5 pilot studies have progressed to a definitive RCT.

Hip microinstability diagnosis and management: a systematic review.

PURPOSE: The purpose of this systematic review is to present the most common causes, diagnostic features, treatment options and outcomes of patients with hip micro-instability. METHODS: Three online databases (MEDLINE, Embase, and PubMed) were searched from database inception March 2022, for literature addressing the diagnosis and management of patients with hip micro-instability. Given the lack of consistent reporting of patient outcomes across studies, the results are presented in a descriptive summary fashion. RESULTS: Overall, there were a total of 9 studies including 189 patients (193 hips) included in this review of which 89% were female. All studies were level IV evidence with a mean MINORS score of 12 (range: 10-13). The most commonly used features for diagnosis of micro-instability on history were anterior pain in 146 (78%) patients and a subjective feeling of instability with gait in 143 (81%) patients, while the most common feature on physical examination was the presence of anterior apprehension with combined hip extension and external rotation in 123 (65%) patients. The most common causes of micro-instability were iatrogenic instability secondary to either capsular insufficiency or cam over-resection in 76 (62%) patients and soft tissue laxity in 38 (31%) patients. CONCLUSION: The most common symptom of micro-instability on history was anterior hip pain and on physical exam was pain with hip extension and external rotation. There are many treatment options and when managed appropriately based on the precise cause of micro-instability, patients may demonstrate improved outcomes. LEVEL OF EVIDENCE: IV.

Labral Tears and Chondral Lesions Are Common Comorbidities Identified During Endoscopic Repair of Gluteal Tendon Tears for Greater Trochanteric Pain Syndrome: A Systematic Review.

PURPOSE: The primary purpose of this study was to systematically review the literature on intraoperative findings during endoscopic treatment for greater trochanteric pain syndrome (GTPS). Secondary outcomes were preoperative imaging findings and postoperative functional outcome measures. METHODS: Medline, PubMED, and Embase databases were searched from inception (1946, 1966, and 1974, respectively), to July 15, 2021, for records reporting intraoperative findings during endoscopic surgery for GTPS. Studies of Level I-IV evidence were eligible. All studies were assessed for quality using the Methodological Index for Non-Randomized Studies (MINORS) score. RESULTS: Sixteen studies met the inclusion criteria. Most patients underwent endoscopic greater trochanteric bursectomy with repair of the gluteal tendons. Intraoperative conditions reported were gluteal tendon tears usually involving the gluteus medius tendon, labral tears, and chondral lesions. Three studies reported an average of 9% of patients who subsequently underwent conversion to total hip arthroplasty. Pain was assessed using the visual analog scale, and functional outcome measures were measured using the modified Harris Hip Score, Non-Arthritic Hip Score, Hip Outcome Score Sport-Specific subscale, Hip Outcome Score Activities of Daily Living subscale, and iHOT-12. Pain and functional outcomes demonstrated significant improvement in nearly all the studies where they were reported. CONCLUSIONS: Patients who underwent endoscopic management of GTPS commonly underwent repair of gluteal tendon tears, and in many cases had concomitant labral tears and chondral lesions identified intraoperatively. There were low rates of adverse events, repair failure, and revision surgery. Patient-reported functional outcomes were improved at follow-up at least 1 year postoperatively. LEVEL OF EVIDENCE: IV, systematic review of level IV or better investigations.

Hip Arthroscopy Improves Outcomes With Moderate Conversion to Total Hip Arthroplasty Rates in Patients Aged 50 Years or Older: A Systematic Review.

PURPOSE: The purpose of this systematic review was to assess the indications, outcomes, and complications of hip arthroscopy in individuals 50 years of age or older over the past 5 years. METHODS: The electronic databases PUBMED, MEDLINE, and EMBASE were searched on March 3, 2022, for studies assessing the use of primary hip arthroscopy for patients aged 50 years or older from the past 5 years. The Methodological Index for Non-randomized Studies (MINORS) was used to assess study quality. Data are presented descriptively. RESULTS: Overall, 17 studies were included, consisting of 6,696 patients (37.5%) with a mean age of 61.4 ± 5.0 years and a median follow-up of 24 months (range: 1.4-70.1). Indications for hip arthroscopy in patients aged 50 years or older were unspecified/undefined (93.8%), mixed pathology (i.e., combined femoroacetabular impingement [FAI], labral tear, osteoarthritis, etc.) (2.7%), and FAI (2.6%). Eleven studies demonstrated significant improvement in functional outcome scores from baseline to final follow-up. Of the 6 studies that compared outcomes across multiple age groups, 3 demonstrated significantly worse functional outcomes, and 2 demonstrated significantly higher rates of conversion to THA for older patients compared to younger patients. Lastly, the overall complication rates ranged from 0 to 38.3%. The rate of conversion to THA ranged from 0 to 34.6%, occurring between 6 and 60 months postoperatively. CONCLUSIONS: Hip arthroscopy for patients aged 50 years or older yields significant improvements in patient-reported outcomes postoperatively compared to baseline, with a moderate rate of conversion to THA (range: 0 to 34.6%). Clinicians should consider patient history (e.g., imaging, comorbidities, etc.) and values when electing for hip arthroscopy in the older population. LEVEL OF EVIDENCE: IV, systematic review of Level III and IV studies.

Performance of 5-Strand Hamstring Autograft Anterior Cruciate Ligament Reconstruction in the STABILITY Study: A Subgroup Analysis.

BACKGROUND: Anterior cruciate ligament (ACL) reconstructions (ACLRs) with graft diameters <8mm have been shown to have higher revision rates. The 5-strand (5S) hamstring autograft configuration is a proposed option to increase graft diameter. PURPOSE: To investigate the differences in clinical outcomes between 4-strand (4S) and 5S hamstring autografts for ACLR in patients who underwent ACLR alone or concomitantly with a lateral extra-articular tenodesis (LET) procedure. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Data from the STABILITY study were analyzed to compare a subgroup of patients undergoing ACLR alone or with a concomitant LET procedure (ACLR + LET) with a minimum graft diameter of 8mm that had either a 4S or 5S hamstring autograft configuration. The primary outcome was clinical failure, a composite of rotatory laxity and/or graft failure. The secondary outcome measures consisted of 2 patient-reported outcome scores (PROs)-namely, the ACL Quality of Life Questionnaire (ACL-QoL) and the International Knee Documentation Committee (IKDC) score at 24 months postoperatively. RESULTS: Of the 618 patients randomized in the STABILITY study, 399 (228 male; 57%) fit the inclusion criteria for this study. Of these, 191 and 208 patients underwent 4S and 5S configurations of hamstring ACLR, respectively, with a minimum graft diameter of 8mm. Both groups had similar characteristics other than differences in anthropometric factors-namely, sex, height, and weight, and Beighton scores. The primary outcomes revealed no difference between the 2 groups in rotatory stability (odds ratio [OR], 1.19; 95% CI, 0.77-1.84; P = .42) or graft failure (OR, 1.13; 95% CI, 0.51-2.50; P = .76). There was no significant difference between the groups in Lachman (P = .46) and pivot-shift (P = .53) test results at 24 months postoperatively. The secondary outcomes revealed no differences in the ACL-QoL (P = .67) and IKDC (P = .83) scores between the 2 subgroups. CONCLUSION: At the 24-month follow-up, there were no significant differences in clinical failure rates and PROs in an analysis of patients with 4S and 5S hamstring autografts of ≥8mm diameter for ACLR or ACLR + LET. The 5S hamstring graft configuration is a viable option to produce larger-diameter ACL grafts.

Effect of a Postoperative Multimodal Opioid-Sparing Protocol vs Standard Opioid Prescribing on Postoperative Opioid Consumption After Knee or Shoulder Arthroscopy: A Randomized Clinical Trial.

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. Trial Registration: ClinicalTrials.gov Identifier: NCT04566250.

Sexual and urinary function post-surgical treatment of femoroacetabular impingement: experience from the FIRST trial and embedded cohort study.

The goal of this study was to investigate the sexual and urinary function and any related complications in patients post-hip arthroscopy for the treatment of femoroacetabular impingement (FAI). Data from 214 patients enrolled in the FIRST trial and 110 patients enrolled in the trial's embedded prospective cohort study (EPIC) were analyzed. EPIC patients either refused to participate in the trial or did not meet the FIRST eligibility criteria. Outcomes included the International Consultation on Continence Questionnaire (ICIQ) for males (ICIQ-MLUTS) and females (ICIQ-FLUTS) and the Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF) administered before surgery and at 6 weeks and 12 months. Urinary and sexual function adverse events were recorded up to 24 months. Linear regression analyses were conducted to compare the osteochondroplasty and lavage groups in the FIRST trial and to evaluate age and traction time as prognostic factors among all patients. Longer traction time was associated with a small but statistically significant improvement in urinary voiding function in males at 6 weeks and 12 months (MD (95% CI) = 0.25 (0.12, 0.39), P < 0.001 and 0.21 (0.07, 0.35), P = 0.004), respectively. Mean traction time was 43.7 (± 23.2) min for FIRST trial and 52.8 (± 15.2) min for EPIC cohort patients. Increasing age in male patients was associated with a decrease in urinary continence at 6 weeks (MD (95% CI) = 0.25 (-0.42, -0.09), P = 0.003). FIRST male patients who received osteochondroplasty improved significantly in sexual function at 12 months compared to males in the EPIC cohort (MD (95% CI) = 2.02 (0.31, 3.72), P = 0.020). There was an overall complication rate of 1.2% at 24 months [one urinary infection, two instances of erectile dysfunction (one transient and one ongoing at 24 months) and one reported transient numbness of tip of the penis]. Hip arthroscopy for the treatment of FAI has a low rate of sexual and urinary dysfunction and adverse events.

Effect of Osteochondroplasty on Time to Reoperation After Arthroscopic Management of Femoroacetabular Impingement: Analysis of a Randomized Controlled Trial.

Background: A subset of patients with femoroacetabular impingement (FAI) fail arthroscopic management. It is not clear which patients will fail surgical management; however, several surgical and patient factors, such as type of procedure and age, are thought to be important predictors. Purpose: This time-to-event analysis with a 27-month follow-up analysis compared the effect of (1) arthroscopic osteochondroplasty with or without labral repair versus (2) arthroscopic lavage with or without labral repair on the time to reoperation in adults aged 18 to 50 years with FAI. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Eligible participants had been randomized in a previous study trial to a treatment of arthroscopic osteochondroplasty or arthroscopic lavage with or without labral repair. Using the comprehensive data set from the Multinational Femoroacetabular Impingement Randomized controlled Trial, all reoperations until 27 months after surgery were identified. The analysis was conducted using a Cox proportional hazards model, with percentage of patients with a reoperation evaluated in a time-to-event analysis as the outcome. The independent variable was the procedure, with age and impingement subtype explored as potential covariates. The effects from the Cox model were expressed as the hazard ratio (HR). All tests were 2-sided, with an alpha level of .05. Results: A total of 108 patients in the osteochondroplasty group and 106 patients in the lavage group were included. The mean age of the patients included in the study was 36 ± 8.5 years. Overall, 27 incident reoperations were identified within the 27-month follow-up, with an incidence rate of 6 per 100 person-years. Within the osteochondroplasty group, 8 incident reoperations were identified (incidence rate, 3.4 per 100 person-years), while within the lavage group, 19 incident reoperations were identified (incidence rate, 8.7 per 100 person-years). The hazard of reoperation for patients undergoing osteochondroplasty was 40% of that of patients undergoing lavage (HR, 0.40 [95% CI, 0.17-0.91] P = .029). Conclusion: This study demonstrated that for adults between the ages of 18 and 50 years with FAI, arthroscopic osteochondroplasty was associated with a 2.5-fold decrease in the hazard of reoperation at any point in time compared with arthroscopic lavage. Registration: NCT01623843 (ClinicalTrials.gov identifier).

A higher proportion of patients may reach the MCID with capsular closure in patients undergoing arthroscopic surgery for femoroacetabular impingement: a systematic review and meta-analysis.

PURPOSE: The purpose of this review is to provide a summary of the techniques and outcomes of various capsular management strategies in patients undergoing hip arthroscopy for femoroacetabular impingement (FAI). The information this review provides on capsular management strategies will provide surgeons with operative guidance and decision-making when managing patients with FAI lesions arthroscopically. METHODS: Three databases MEDLINE, EMBASE, and PubMed were searched from database inception to November 2nd 2021, for literature addressing capsular management of patients undergoing hip arthroscopy for FAI. All level I-IV data on capsular management strategy as well as postoperative functional outcomes were recorded. A meta-analysis was used to combine the mean postoperative functional outcomes using a random-effects model. RESULTS: Overall, there were a total of 36 studies and 4744 patients included in this review. The mean MINORS score was 10.7 (range 8-13) for non-comparative studies and 17.6 (range 15-20) for comparative studies. Three comparative studies in 1302 patients examining the proportion of patients reaching the MCID for the mHHS score in patients undergoing interportal capsulotomy with either capsular repair or no repair found that the capsular repair group had a higher odds ratio of reaching the MCID at 1.46 (95% CI 0.61-3.45, I2 = 67%, Fig. 2, Table 3); however, this difference was not significant with a p value of 0.39. When looking at only level 1 and 2 studies, four studies in 1308 patients reporting on the mHHS score in patients undergoing capsular closure regardless of capsulotomy type, found a pooled standardized mean difference in the mHHS score of 2.1 (95% CI 1.7-2.55, I2 = 70%, Fig. 3), while four studies in 402 patients reporting on the mHHS score in patients not undergoing capsular closure regardless of capsulotomy type found a pooled standardized mean difference in the mHHS score of 1.46 (95% CI 1.2-1.7, I2 = 30%, Fig. 4). CONCLUSION: This review may demonstrate improved postoperative outcomes in patients undergoing complete capsular closure regardless of capsulotomy type based on postoperative mHHS score. Furthermore, this review may suggest improved postoperative outcomes after closure of an interportal capsulotomy. There are limited published outcome data regarding T-type capsulotomy without closure. This review provides surgeons with operative guidance on capsular management strategies when treating patients with FAI lesions arthroscopically. LEVEL OF EVIDENCE: IV.

Surgical Soft Tissue Management for Glenohumeral Deformity and Contractures in Brachial Plexus Birth Injury : A Systematic Review and Meta-analysis.

PURPOSE OF THE REVIEW: Consensus on the effects of soft tissue surgical intervention in the management of brachial plexus birth injury (BPBI) sequalae is lacking. The purpose of this review is to examine the available literature on the functional and structural outcomes following soft tissue surgical management of BPBI sequalae. RECENT FINDINGS: EMBASE, PubMed, and MEDLINE were searched for related literature from the point of database inception until April 2021. Relevant papers were screened by two reviewers independently and in duplicate. A meta-analysis was performed using a random effects model. A total of 25 studies (852 patients) were included in the review, with the number included in each meta-analysis varying based on outcome of interest. There were significant improvements from pre- to post-operative time points for the following measures: Mallet aggregate scores (5.0 points, p<0.0001), active external rotation in adduction (48.9°, p=0.003), passive external rotation in adduction (64.6°, p< 0.00001), active abduction (46.2°, p<0.00001), glenoid version (14.4°, p< 0.00001), and percentage of the humeral head anterior to the scapular line (17.53°, p< 0.00001). Furthermore, data revealed an overall complication rate of 9.3% (79/852 patients) and a major complication rate of 0.47% (4/852 patients). Patients with BPBI sequela experience statistically significant improvements in functional, structural, and range of motion outcomes of the GH joint following soft tissue surgical management. Understanding the ideal indications for each procedure and age of surgical management with future prospective studies will help to optimize surgical management of these patients.

Predictors of Graft Failure in Young Active Patients Undergoing Hamstring Autograft Anterior Cruciate Ligament Reconstruction With or Without a Lateral Extra-articular Tenodesis: The Stability Experience.

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction (ACLR) has higher failure rates in young active patients returning to sports as compared with older, less active individuals. Augmentation of ACLR with an anterolateral procedure has been shown to reduce failure rates; however, indications for this procedure have yet to be clearly defined. PURPOSE/HYPOTHESIS: The purpose of this study was to identify predictors of ACL graft failure in high-risk patients and determine key indications for when hamstring ACLR should be augmented by a lateral extra-articular tenodesis (LET). We hypothesized that different preoperative characteristics and surgical variables may be associated with graft failure characterized by asymmetric pivot shift and graft rupture. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Data were obtained from the Stability 1 Study, a multicenter randomized controlled trial of young active patients undergoing autologous hamstring ACLR with or without a LET. We performed 2 multivariable logistic regression analyses, with asymmetric pivot shift and graft rupture as the dependent variables. The following were included as predictors: LET, age, sex, graft diameter, tear chronicity, preoperative high-grade knee laxity, preoperative hyperextension on the contralateral side, medial meniscal repair/excision, lateral meniscal repair/excision, posterior tibial slope angle, and return-to-sports exposure time and level. RESULTS: Of the 618 patients in the Stability 1 Study, 568 with a mean age of 18.8 years (292 female; 51.4%) were included in this analysis. Asymmetric pivot shift occurred in 152 (26.8%) and graft rupture in 43 (7.6%). The addition of a LET (odds ratio [OR], 0.56; 95% CI, 0.37-0.83) and increased graft diameter (OR, 0.62; 95% CI, 0.44-0.87) were significantly associated with lower odds of asymmetric pivot shift. The addition of a LET (OR, 0.40; 95% CI, 0.18-0.91) and older age (OR, 0.83; 95% CI, 0.72-0.96) significantly reduced the odds of graft rupture, while greater tibial slope (OR, 1.15; 95% CI, 1.01-1.32), preoperative high-grade knee laxity (OR, 3.27; 95% CI, 1.45-7.41), and greater exposure time to sport (ie, earlier return to sport) (OR, 1.18; 95% CI, 1.08-1.29) were significantly associated with greater odds of rupture. CONCLUSION: The addition of a LET and larger graft diameter were significantly associated with reduced odds of asymmetric pivot shift. Adding a LET was protective of graft rupture, while younger age, greater posterior tibial slope, high-grade knee laxity, and earlier return to sport were associated with increased odds of graft rupture. Orthopaedic surgeons should consider supplementing hamstring autograft ACLR with a LET in young active patients with morphological characteristics that make them at high risk of reinjury.

Glenohumeral Internal Rotation Deficit in the Adolescent Overhead Athlete: A Systematic Review and Meta-Analysis.

OBJECTIVE: The objective of this review was to investigate the average glenohumeral internal rotation deficit (GIRD) in the dominant arm of adolescent overhead athletes and to examine the association with shoulder and elbow injuries. DESIGN: Systematic review and meta-analysis. SETTING: MEDLINE, Embase, and PubMed were searched from inception to August 1, 2020. PARTICIPANTS: Adolescent overhead athletes with glenohumeral range of motion (ROM) measurements. INTERVENTIONS: Nonoperative treatments of GIRD. MAIN OUTCOME MEASURES: Glenohumeral ROM measurements comparing the dominant and nondominant extremities were pooled in a meta-analysis. RESULTS: Twenty-five studies were included in this review, which involved 2522 overhead athletes. Pooled internal rotation (IR) deficit of the dominant arm was 9.60° (95% confidence interval [CI] 7.87°-11.32°, P < 0.00001), with an external rotation (ER) gain of 6.78° (95% CI 4.97°-8.59°, P < 0.00001) and a total ROM (TROM) deficit of 1.78° (95% CI -0.70° to 4.26°, P = 0.16). The association between GIRD and shoulder or elbow injury was not clearly defined. Two studies reported treatment, and both used nonoperative treatment in the form of physiotherapy and sleeper stretches. CONCLUSIONS: The adolescent overhead athlete has roughly 10° of IR deficit in their dominant arm, accompanied by nearly 7° of ER gain, with similar ROM measurements for injured and uninjured athletes. Those with pathological GIRD have a greater degree of IR deficit, but without an accompanying compensatory increase in ER, leading to a TROM deficit of nearly 15°. Surgical treatment in the absence of other indications is rare, whereas physiotherapy and sleeper stretches remain the first-line treatment.

Return to Sport After Surgical Management of Posterior Shoulder Instability: A Systematic Review and Meta-analysis.

BACKGROUND: Posterior shoulder instability accounts for a small proportion of all shoulder instability, although it can affect athletes of all types, from contact to overhead athletes. Surgical treatment is quite successful in these patients; however, the literature reports a wide range of rates of return to sport. PURPOSE/HYPOTHESIS: The purpose was to determine the return-to-sport rates after surgical stabilization for posterior shoulder instability. It was hypothesized that patients would experience a high rate of return to sport. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: Embase, PubMed, and MEDLINE were searched for relevant literature from database inception until April 2020, and studies were screened by 2 reviewers independently and in duplicate for studies reporting rates of return to sport after surgical management of posterior shoulder instability. Demographic data as well as data on return to sport and functional outcomes were recorded. A meta-analysis of proportions was used to combine the rates of return to sport using a random effects model. A risk of bias was assessed for all included studies. RESULTS: Overall, 32 studies met inclusion criteria and comprised 1100 patients (1153 shoulders) with a mean age of 22.8 years (range, 11-65) and a mean follow-up of 43.2 months (range, 10-228). The pooled rate of return to any level of sport was 88% (95% CI, 84%-92%; I2 = 68.7%). In addition, the pooled rate of return to the preinjury level was 68% (95% CI, 60%-76%; I2 = 79%). Moreover, the pooled return-to-sport rate for contact athletes was 94% (95% CI, 90%-97%; I2 = 0%), while for throwing athletes it was 88% (95% CI, 83%-92%; I2 = 0%). CONCLUSION: Surgical management of posterior shoulder instability resulted in a high rate of return to sport, as well as significant pain reduction and functional improvement in most patients. However, only two-thirds of athletes can return to their preinjury levels of sport.

Bilateral hip arthroscopy for treating femoroacetabular impingement: a systematic review.

PURPOSE: Femoroacetabular impingement (FAI) is a hip disorder which can often present bilaterally. The purpose of this systematic review was to explore the current practices for bilateral hip arthroscopy in treating FAI as they relate to outcomes and complications. METHODS: This review has been conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). The electronic databases PubMed, MEDLINE, EMBASE, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched from data inception to October 18th, 2020. The Methodological Index for Non-randomized Studies (MINORS) was used to assess study quality. Data are presented descriptively. RESULTS: Overall, 19 studies were identified, comprising 957 patients (48.6% male) with a mean age of 27.9 ± 7.1 years and a mean follow-up of 31.7 ± 20.8 months. The majority of patients were treated with a staged bilateral hip arthroscopy (78.5%) with a mean duration between surgeries of 7.1 ± 4.0 months. Significant preoperative-to-postoperative improvements for clinical outcomes such as pain, hip function, and health-related daily living as well as radiographic outcomes were reported in six studies for staged procedures (p < 0.05) and three studies for simultaneous procedures (p < 0.02). Significant improvements in patient-reported outcomes (e.g., HOS-ADL, Pain, HOS-SS, mHHS, and NAHS) were found in favor of those undergoing a shorter delay between surgeries in three studies (i.e., < 3, 10 or 17 months) (p < 0.05) compared to those who had delayed surgeries (i.e., > 3, 10, or 17 months). The overall complication rate was 10.1% (97/957). CONCLUSIONS: Bilateral surgery for FAI yields improved outcomes postoperatively and complication rates similar to unilateral surgery. The overall complication rate was 10.1% with the most common complication being revision surgery. Staged bilateral surgery is more commonly performed than simultaneous surgery. Clinicians should consider preoperative imaging, clinical history, and patient values when deciding between staged and simultaneous procedures for bilateral FAI surgery. Future studies are required to determine the optimal indications for simultaneous versus staged procedures, as well as the ideal timing between surgeries for the latter. LEVEL OF EVIDENCE: Level IV.

Osteochondroplasty Benefits the Pragmatic Patient With Femoroacetabular Impingement: Analysis From the Embedded Prospective Cohort of the Femoroacetabular Impingement RandomiSed Controlled Trial (FIRST).

PURPOSE: To determine whether arthroscopic osteochondroplasty demonstrated effectiveness in a pragmatic femoroacetabular impingement patient population embedded within FIRST (the Femoroacetabular Impingement RandomiSed controlled Trial). METHODS: All cohort patients were not randomized and were followed prospectively with a follow-up assessment protocol identical to that in FIRST. The primary outcome was hip pain using a 100-point visual analog scale. Secondary outcomes included hip function (Hip Outcome Score, International Hip Outcome Tool-12), health utility (EuroQol 5 Dimensions), and health-related quality of life (Short Form-12) at 12 months, as well as operatively and nonoperatively treated hip complications at 24 months. We performed multivariable regressions to compare these outcomes between 3 groups of patients: (1) those randomized to lavage in FIRST, (2) those randomized to osteochondroplasty in FIRST, and (3) those who received osteochondroplasty as part of the cohort study. RESULTS: All groups had improvements across all questionnaire outcomes from baseline to 12 months, with no significant differences. There were significantly more reoperations in the lavage trial group compared with those in the embedded cohort (adjusted odds ratio [aOR] 3.08; 95% confidence interval [CI] 1.23-7.73; P = .016). There were significantly more nonoperatively treated hip complications in the lavage trial group and in the osteochondroplasty trial group when compared with those in the embedded cohort (aOR 3.81; 95% CI 1.19-12.17; P = .024 and aOR 4.55; 95% CI 1.43-14.42; P = .010, respectively). CONCLUSIONS: Hip arthroscopic osteochondroplasty and lavage led to improvement in hip pain, function, and health-related quality of life at 12 months across both randomized controlled trial (RCT) and cohort patients. The pragmatic cohort receiving osteochondroplasty had (1) significantly fewer complications than RCT patients, (2) significantly less reoperations than RCT patients randomized to arthroscopic lavage, and (3) fewer, although nonsignificant, reoperations than RCT osteochondroplasty patients. LEVEL OF EVIDENCE: II, therapeutic.
