Return to Sport After Hip Arthroscopy for Femoroacetabular Impingement Syndrome in NCAA Division I Athletes: Experience at a Single Institution

Arthroscopic Management of Femoroacetabular Impingement: Current Concepts

Background: Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction, especially in young and active individuals, and it may require surgical management for associated labral tears and cartilage damage. The management of FAI has advanced radically over the last few years, and hip arthroscopy has gained a leading role. However, despite the increasing number of published research and technological advancements, a comprehensive systematic review summarising current evidence is still missing. Methods: All the clinical studies investigating the arthroscopic management of FAI were accessed. Only studies with a minimum of six months of follow-up were considered. The 2020 PRISMA guidelines were followed. In December 2024, PubMed, Web of Science, and Embase were accessed without time constraints. Results: The present systematic review included 258 clinical investigations (57,803 patients). The mean length of follow-up was 34.2 ± 22.7 months. The mean age was 34.7 ± 5.3, and the mean BMI was 25.1 ± 2.0 kg/m2. Conclusions: The present systematic review updates current evidence on patients who have undergone arthroscopic surgery for FAI, updating and discussing current progress in managing labral injuries and patient selection, emphasising outcomes and pitfalls. Progress in surgery and improvement in eligibility criteria, as well as current controversies and prospects, were also discussed.

Return-to-sports criteria used by professional team physicians in elite athletes after hip arthroscopy - a qualitative study

OBJECTIVES

The purpose of this study was to explore currently utilized readiness to Return to Sport (RTS) criteria after Hip Arthroscopy (HA) used in elite athletes to gain novel insights into the RTS decision-making process of professional team physicians. The authors hypothesized that even among this group of highly specialized physicians, there exists variability of measures and criteria used to determine RTS after HA.

METHODS

A total of 15 qualitative semi-structured interviews with professional team physicians were conducted by a single trained interviewer. The interviews were used to identify team physician concepts and themes regarding the criteria used to determine RTS after HA. Themes and sub-themes were identified using a general inductive analysis and a coding process. A hierarchical approach in coding helped to link themes.

RESULTS

Four key themes and several subordinate themes were identified from the interviews that seem to influence the return to sports decision. The most important RTS criteria were muscle strength (especially symmetric hip strength and muscle bulk with low side-to-side variance compared to the contralateral side) followed by pain-free sport-specific activity (pain-free drill skills and play at a lower level), physical examination (with major emphasis on the absence of hip pain with a painless hip range of motion compared to the contralateral side), and functional testing (including full squats, Ober test, FABER test, and pain-free FADIR position).

CONCLUSION

Besides objective findings, including muscle strength, we identified time after surgery as well as subjective findings, including absence of pain and feedback of clinical team members that influence RTS decision after HA. We showed that even among specialized professional team physicians, the main criteria to RTS in these categories were not consistent necessitating the further development of specific RTS guidelines.

State of the Art in Rehabilitation Strategies After Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Systematic Review

Background/Objectives: Femoroacetabular impingement (FAI) is a common cause of hip pain in athletes and active individuals, often requiring hip arthroscopy followed by a structured rehabilitation program. Effective rehabilitation is crucial for optimizing surgical outcomes and facilitating a return to sport. Methods: A systematic review following PRISMA guidelines was conducted to evaluate post-operative rehabilitation protocols after hip arthroscopy for FAI. Databases searched included PubMed, Embase, and Cochrane Library up to April 2024. Inclusion criteria focused on studies documenting rehabilitation post-arthroscopy for FAI, with a final selection of 14 studies encompassing 1105 patients. Data extraction focused on rehabilitation techniques, functional outcomes, and return-to-sport rates. The risk of bias was assessed using RoB2 and ROBINS-I tools. Results: Rehabilitation protocols were categorized into four phases, emphasizing manual therapy, strengthening, stretching, aquatic exercises, and sport-specific drills. The average return-to-sport rate was 90.3%. Manual therapy and aquatic programs were critical in early recovery, while strengthening and proprioception exercises were central to later stages. Variability in protocols across studies was noted. Conclusions: Post-operative rehabilitation following hip arthroscopy for FAI is essential for recovery. A phased, individualized approach, integrating manual therapy, aquatic exercises, and sport-specific training, yields positive outcomes. However, the heterogeneity of protocols suggests the need for standardized guidelines tailored to individual patient needs and activity levels.

Females Have Higher Return-to-Sport Rate Than Males Among Collegiate Athletes After Hip Arthroscopy for Femoroacetabular Impingement Due to the Difference in the Type of Sports, Type of Impingement, and Prevalence of Severe Cartilage Damage

PURPOSE

To investigate the return to sport (RTS) rate and the sex-based difference of collegiate athletes after arthroscopic treatment for femoroacetabular impingement (FAI).

METHODS

Patients who were collegiate athletes at the time of surgery and underwent hip arthroscopy for treatment of FAI between January 2009 and June 2020 were included. Patients were excluded if they were in their final year of eligibility, graduated, retired, or had plans to retire from collegiate play before surgery. Publicly available data were collected regarding each patient's collegiate team and division and RTS status after surgery. Comparisons were made based on the RTS status and gender.

RESULTS

Of the 181 hips (144 athletes) who met the inclusion criteria, 114 were male (63%) and 67 were female (37%), with a median age of 20.4 (range: 18.0-24.5). Eighty-six percent (155 hips) returned to sport at the collegiate level after hip arthroscopy. Males were significantly less likely to return to sport compared with females (82% vs 93%, odds ratio = 2.8, 95% confidence interval: 1.003-7.819, P = .042). Males participated in more contact sports (26% vs 1.5%, P < .001) and had more mixed-type FAI (95.6% vs 80.6%, P = .003) compared with females. In addition, males had more grade 3/4 chondral defects (28% vs 13%, P = .023) and underwent microfracture more frequently (11% vs 3%, P = .047). Further, males had significantly larger postoperative alpha angles (46.2 vs 43.6, P < .001).

CONCLUSIONS

Collegiate athletes were found to have a high RTS rate of 86% after arthroscopy for the treatment of FAI; however, males were less likely to RTS compared with females. Sex-based differences were identified in the type of sports, type of FAI, prevalence of severe cartilage damage, and postoperative alpha angle.

The Definition of Failure in Hip Arthroscopy May Include Factors Outside of Reoperation: A Systematic Review

Purpose

To perform a systematic review about the varying definitions of "failure" of hip arthroscopy (HA) in the current literature and to provide a recommendation for the standardization of defining failure of HA.

Methods

A systematic search of electronic databases was conducted to identity Level I-IV clinical studies on HA failure published between January 2016 and July 2021 according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Inclusion criteria consisted of studies of patients who underwent an arthroscopic hip procedure and included a definition of failure. Studies with patients who underwent open hip procedures and non-full-text articles were excluded.

Results

Of 1,290 titles, 85 (6.6%) met inclusion criteria and were analyzed in this review. The most common definition of HA failure used was the need for any subsequent ipsilateral hip surgery (80/85, 94.1%). Among studies that noted reoperation as a cause for failure, conversion to total hip arthroplasty was most frequently cited (66/85, 77.6%) followed by any other reoperation on the ipsilateral hip, including repeat HA, hip resurfacing, and hip periacetabular osteotomy (65/85, 76.5%). Multiple studies used subjective patient-reported outcomes, with use of the modified Harris Hip Score being the most common (17/85, 20%).

Conclusions

There are numerous definitions of the term "failure" of HA used by authors in the peer-reviewed literature. A standardized definition of HA failure should be multifactorial. It may include any unplanned subsequent procedures; patient-reported outcomes with emphasis on minimal clinically important difference, substantial clinical benefit, and/or patient acceptable symptom state values; and the inability to return to normal function or sports.

Return to Sport Following Arthroscopic Management of Femoroacetabular Impingement: A Systematic Review

Background: Femoroacetabular impingement (FAI) is common. The present systematic review updates the current evidence on return to sport (RTS) in patients who have undergone arthroscopic surgery for FAI in any of its variants (CAM, pincer, or both). Methods: The outcomes of interest were sports-related patient-reported outcome measures (PROMs) and the level and time to RTS. All available clinical studies concerning the RTS following arthroscopic management of FAI were considered. In July 2024, the following databases were accessed following the PRISMA guidelines: Embase, Web of Science, and PubMed. Only studies with a minimum of six months of follow-up were eligible. Results: From 1245 initially identified articles, 43 studies (4103 patients) met the inclusion criteria, in which 32.1% (1317 of 4103 patients) were women. The mean length of follow-up was 33.7 ± 15.8 months. The mean age was 28.1 ± 7.2 years, the mean BMI was 24.7 ± 6.4 kg/m2, and 79.6% ± 27.8% of patients returned to sport at the same or higher level at a mean of 14.3 ± 9.6 months. The mean time away from sports was 8.0 ± 3.3 months. Conclusion: Arthroscopic management for FAI leads to a high rate of RTS, with approximately 80% of patients returning to their preinjury level. Future research should focus on standardised definitions of RTS, sport-specific rehabilitation protocols, and the influence of deformity and procedures on RTS.

Sex-Based Differences in Prevalence, Outcomes, and Complications of Hip Arthroscopy for Femoroacetabular Impingement: A Systematic Review and Meta-analysis

Background

Trends between the sexes have been reported regarding prevalence, patient-reported outcomes (PROs), and complications of hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS), yet current results lack consensus.

Purpose

To evaluate sex-based differences after HA for FAIS in (1) prevalence of cam and pincer morphology in FAIS and (2) PROs, pain scores, and postoperative complication rates.

Study Design

Systematic review; Level of evidence, 4.

Methods

The EMBASE, PubMed, and Ovid (MEDLINE) databases were searched from establishment to February 28, 2022, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included studies had sex-based data on prevalence, outcomes, and complications of HA for FAIS. Reviews and commentaries were excluded. Data were combined, and between-sex differences were analyzed. Meta-analyses using random-effects models were performed when possible. Pooled risk ratios (RRs) and standardized mean differences were calculated.

Results

A total of 74 studies were included (213,059 patients; 132,973 female hips [62.4%] and 80,086 male hips [37.6%]). The mean age was 30.7 ± 7.7 years among male patients and 31.1 ± 7.8 years among female patients. Male patients experienced mixed-type impingement significantly more often (39.4% vs 27.2% for female patients; RR = 0.69 [95% confidence interval [CI], 0.58-0.81]; P < .001), whereas female patients experienced pincer-type impingement more often (50.6% vs 30.8% for male patients; RR = 2.35 [95% CI, 1.14-4.86]; P = .02). Male patients had higher likelihoods of undergoing femoroplasty (89.8% vs 77.4% for female patients; RR = 0.90 [95% CI, 0.83-0.97]; P = .006), acetabuloplasty (67.1% vs 59.3% for female patients; RR = 0.87 [95% CI, 0.79-0.97]; P = .01), or combined femoroplasty/acetabuloplasty (29.2% vs 14.5% for female patients; RR = 0.63 [95% CI, 0.44-0.90]; P = .01). Although female patients showed greater improvements in Hip Outcome Score-Sport-Specific subscale (P = .005), modified Harris Hip Score (P = .006), and visual analog scale pain (P < .001), both sexes surpassed the minimal clinically important difference at 1, 2, and 5 years postoperatively. Female patients had higher complication rates (P = .003), although no sex-based differences were found in total hip arthroplasty conversion rates (P = .21).

Conclusion

Male patients undergoing HA for FAIS had a higher prevalence of mixed-type FAIS while female patients had more pincer-type FAIS. Female patients gained greater improvements in PROs, although both sexes exceeded the minimal clinically important difference, suggesting that both male and female patients can benefit from HA.

Comparative analysis between operative and non-operative acetabular labral tear injuries in division 1 collegiate athletes

Acetabular labral tears have shown to be difficult to diagnose and manage in an active and competitive athletic population. The goal of this study was to compare NCAA Division 1 collegiate athletes undergoing operative and non-operative management of their labral injuries by assessing ability to return to competition and secondarily evaluate days lost from sport. A retrospective cohort analysis was conducted on Division 1 collegiate athletes from 2005 to 2020, incorporating all varsity university sports. Records showing MRI confirmed diagnosis were included in the cohort, as well as all pertinent clinical data. Data revealed 10/18 (55%) of individuals managed conservatively versus 23/29 (79%) surgically (p-value = 0.0834) were able to return to sport following treatment. Of those athletes, 22 surgical patients experienced a mean of 324 days ± 223 days lost from sport and nine conservatively managed patients experienced a mean of 27 days ± 70 lost days (p-value < 0.001) Seven of nine conservatively managed patients were able to continue competition while undergoing treatment. Findings suggest no statistical significance regarding operative vs non-operative management of acetabular labral tears. The majority of athletes returning to sport and treated conservatively were able to resume competition during treatment. Therefore, treatment of these injuries should be individualized based on athlete's symptoms.

Why Is There a Range in Time Returning to Preoperative Activity Habits After Femoroacetabular Impingement Treatment in Recreational Athletes?

CONTEXT

Professional athletes showed excellent results after hip preserving procedures. However, there is still a lack of knowledge regarding the rate of return to activity and the rehabilitation time of recreational athletes. Thus, the aim of this study was to investigate factors that were associated with an extended return-to-activity time in nonprofessional athletes.

DESIGN

Retrospective, quantitative case-control study.

METHODS

This study included 47 cases (45 nonprofessional athletes), which were divided according to return-to-activity time (short term: 0.0-7.0 mo vs long term: >7.0 mo). The clinical outcome were evaluated with the modified Harris hip score, the nonarthritic hip score, the Western Ontario and McMaster Universities Osteoarthritis Index, and the University of California, Los Angeles activity score. For statistical analysis between both groups, an unpaired student t test and a paired Wilcoxon test were used. In addition, the sports behavior, intraoperative findings, and surgical procedures were also assessed.

RESULTS

After a mean follow-up of 4.3 years (±0.6; 3.4-5.6), the overall postoperative modified Harris hip score was 81.8 points, the nonarthritic hip score was 75.8 points, the Western Ontario and McMaster Universities Osteoarthritis Index was 36.7 points, and the University of California, Los Angeles activity score was 7.9. Compared with the preoperative results, all scores improved significantly (P < .001). Patients of the short-term return-to-activity group showed a higher preoperative activity diversity and, postoperatively, a higher rate in high-impact sports (P = .024).

CONCLUSIONS

After mini-open arthrotomy for femoroacetabular impingement syndrome treatment, 92.5% of the recreational athletes returned to sports activity. The findings did not detect factors influencing the return-to-activity time. However, a higher preoperative diversity of activities and a shift to high-level impact sport activities might support a shorter rehabilitation.

Midterm results after arthroscopic femoral neck osteoplasty combined with labral debridement for cam type femoroacetabular impingement in active adults

INTRODUCTION

Arthroscopic labral procedures are frequently undertaken in patients with femoroacetabular impingement (FAI). The role of arthroscopic femoral neck osteoplasty is well established, but less is known about labral procedures. This study evaluates the midterm efficacy and feasibility of arthroscopic osteoplasty with concomitant labral debridement for cam impingement in active adults.

METHODS

The present study was conducted according to the STROBE Statement. All 108 patients who underwent primary hip arthroscopy for cam type FAI combined with labral debridement were considered. Axial and anteroposterior plain radiographs of the pelvis were obtained preoperatively to identify the cam deformity and assess the presence of osteoarthritis, the lateral centre-edge angle, and the alpha angle. The ROM (flexion, extension, abduction, adduction, and intra/extra rotation) was evaluated. The following PROMs were administered: visual analogic scale (VAS), Tegner Activity Scale, non-arthritic hip score (NAHS), the international Hip Outcome Tool (iHOT-33) overall score, and related subscales: symptoms and functional limitations, sports and recreational activities, job-related concerns, and social, emotional, and lifestyle concerns.

RESULTS

At a mean of 2.0 ± 1.1 months, all 108 patients returned to their daily activities with no limitation. At a mean of 2.6 ± 1.4 months, all 108 patients were able to return to sport with no limitation. At 11.9 ± 2.1-month follow-up, no differences were reported in the range of motion compared to baseline: flexion (P = 0.3), extension (P = 0.09), abduction (P = 0.1), adduction (P = 0.3), internal rotation (P = 0.4), and external rotation (P = 0.6). At 72.8 ± 21.7-month follow-up, the mean VAS score was 1.7 ± 3.0, Tegner Activity Scale 3.5 ± 1.4, NAHS 92.1 ± 21.5, iHOT33 83.3 ± 27.2. At a mean of 21.7 ± 15.5 months following the index procedure, 14 of 108 patients had undergone total hip arthroplasty. No further revisions or complications were reported.

CONCLUSION

Arthroscopic femoral neck osteoplasty with concomitant labral debridement for cam type of FAI in active adults yields the reliable results, with a rate of progression to total hip arthroplasty of 13% (14 of 108) at 3-year follow-up. All patients returned to their daily activities with no limitation 2 months postoperatively. Within 3 months, all patients returned to sport with no limitations. No complication related to the index procedure was reported, and no further arthroscopic procedures were necessary.

Driving performance and turning reaction time following hip arthroscopy for FAIS: does capsular repair matter?

PURPOSE

(1) To compare the pre- and postoperative driving performance in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS); (2) to examine the differences in driving performance between patients with versus without capsular repair.

METHODS

Patients who underwent arthroscopic hip surgery for FAIS were included. Driving performance of participating patients was collected using a driving simulator preoperatively and at 2 weeks, 4-6 weeks and 8-12 weeks postoperatively. Data collected included demographics, surgery laterality, intraoperative procedures, left and right turn reaction time, total turn reaction time, gas off time (GOF), and break reaction time (BRT). Repeated measures analysis of variance (ANOVA) was used for statistical analysis.

RESULTS

21 subjects (9 males, 12 females) with a mean age of 30 ± 9 years were included and 57.1% of the subjects had right-sided surgery. There was no difference between the mean preoperative and the 2-week postoperative left (0.72 seconds and 0.75 seconds, respectively) right (0.77 seconds and 0.75 seconds, respectively), and total (0.74 seconds and 0.75 seconds, respectively) turn reaction times as well as GOF (0.62 seconds and 0.60 seconds, respectively) and BRT (0.92 seconds and 0.93 seconds, respectively), indicating that the patients' driving performance returned to the preoperative level as early as 2 weeks following hip arthroscopy for FAIS. There was no significant difference amongst any of the driving variables between patients who underwent capsular repair (50%) and those who did not. There was no significant difference amongst any of the driving variable s between patients who underwent left versus right hip arthroscopy.

CONCLUSIONS

Patients' driving performance returns to the preoperative level as early as 2 weeks after hip arthroscopy for FAIS. Surgery laterality nor capsular repair make any significant difference in the time for driving abilities to return to baseline. The impact of intraoperative procedures performed, and the analgesic medications used postoperatively on the driving ability of patients undergoing hip arthroscopy warrants further investigation in larger patient populations.

Editorial Commentary: Earlier Hip Arthroscopy May Result in Improved Outcomes for Femoroacetabular Impingement Syndrome in Symptomatic Athletes: No Time Like the Present Could Mean Better Luck Next Year

Hip arthroscopy is an effective tool to address hip pain and dysfunction related to femoroacetabular impingement syndrome (FAIS), and an increasing volume of evidence suggests improved outcomes of these procedures if they are done closer to the onset of symptoms. Although this same relationship is observed in competitive athletes, these patients often have competing priorities when deciding if and when to proceed with surgical management of FAIS, including the desire to complete a competitive season, scouting and scholarship considerations, and financial incentives. Despite these incentives, consideration may be given to earlier surgical management, given the improved outcome potential and high rates of return to play. However, caution should be taken, particularly in the elite athlete population, as return to play data may not paint the whole picture, and there remains a paucity of data on sport performance after hip arthroscopy for FAIS.

Basketball Players Undergoing Primary Hip Arthroscopy Exhibit Higher Grades of Acetabular Cartilage Damage but Achieve Favorable Midterm Outcomes and Return to Sports Rates Comparable With a Propensity-Matched Group of Other Cutting Sports Athletes

BACKGROUND

Favorable short-term outcomes in competitive basketball players have been reported. Midterm outcomes in these athletes and how they compare with athletes in sports with similar demands have not been well established.

PURPOSE

(1) To report minimum 5-year patient-reported outcomes (PROs) and return to sports data in competitive basketball players undergoing primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and (2) to compare outcomes with a propensity-matched control group of other cutting sports athletes.

STUDY DESIGN

Cohort study, Level of evidence, 3.

METHODS

Data were prospectively collected and retrospectively reviewed for basketball players who competed at the professional, collegiate, high school, or competitive amateur levels and underwent primary hip arthroscopy for FAIS between May 2009 and March 2016. Patients with preoperative and minimum 5-year postoperative outcomes for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain were included. Patients were propensity matched to athletes in other cutting sports (soccer, lacrosse, field hockey, and tennis) according to age, sex, body mass index (BMI), and preoperative competition level for comparison.

RESULTS

A total of 28 competitive basketball players were included, with a mean follow-up time of 67.1 ± 5.1 months and a mean BMI of 23.7 ± 4; there were 12 (42.9%) female athletes. The cohort was composed of 1 professional, 10 collegiate, 13 high school, and 4 organized amateur athletes. They demonstrated significant improvements in all recorded PROs from baseline to the minimum 5-year follow-up (P < .001) and had high rates of achieving the minimal clinically important difference (MCID) for the mHHS (75%), NAHS (75%), HOS-SSS (67.9%), and VAS for pain (71.4%). Furthermore, 76.5% of basketball players who returned to sports were still competing at a minimum of 5 years postoperatively. When compared with a propensity-matched cohort of other cutting athletes, basketball athletes demonstrated a significantly higher acetabular labrum articular disruption (ALAD) grade (P < .001) and trended toward a higher Outerbridge grade of the acetabular cartilage (P = .067). Despite this, basketball players demonstrated similar preoperative, postoperative, and improvement scores in all recorded PROs. Moreover, both groups exhibited similar rates of achieving psychometric thresholds and rates of continued sports participation at minimum 5-year follow-up.

CONCLUSION

Competitive basketball players undergoing primary hip arthroscopy for FAIS demonstrated significant improvements in all recorded PROs and high rates of continued play at a minimum 5-year follow-up. When compared with a control group of other cutting sports athletes, basketball players exhibited more severe ALAD grades intraoperatively but similar midterm outcomes.

Femoroacetabular Impingement in Elite Skiers and Snowboarders: Return to Sports and Outcomes After Hip Arthroscopy

BACKGROUND

Hip arthroscopy has been shown to be an effective treatment for femoroacetabular impingement (FAI) in high-level athletes; however, limited outcome and return-to-play data exist for hip arthroscopy in skiers and snowboarders.

PURPOSES

To determine the return-to-sports rate of elite skiers and snowboarders who have undergone hip arthroscopic surgery for FAI and to assess hip-related outcomes at a minimum 2-year follow-up.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Elite skiers and snowboarders who underwent hip arthroscopy for the treatment of FAI between 2005 and 2018 were identified via a retrospective review of prospectively collected data. Data were obtained from fis-ski.org, usskiandsnowboard.org, xgames.com, and wikipedia.org, including information on each player's career length, participation on a national team, and time between surgery and first competition after surgery. Patient-reported outcomes (PROs) were prospectively collected preoperatively and at minimum 2 years postoperatively.

RESULTS

In total, 26 elite skiers and snowboarders (34 hips) were included. The mean ± standard deviation age at surgery was 24.5 ± 6.7 years (range, 18.7-46.8 years). A total of 85% (22/26) returned to elite-level competition at 8.9 months (range, 2.9-23.7 months) with an average career length of 3.6 ± 2.7 years after surgery. Four athletes (5 hips) required revision arthroscopy, with adhesions being the most frequent indication. At a mean follow-up of 7.7 ± 3.2 years, significant improvement in PROs (P < .05) was demonstrated for the Hip Outcome Score (HOS)-Activities of Daily Living (from 76 ± 20 to 95 ± 6), HOS-Sport Specific Subscale (from 63 ± 28 to 92 ± 14), modified Harris Hip Score (from 70 ± 19 to 89 ± 12), and 12-Item Short Form Health Survey Physical Component Summary (from 45 ± 11 to 54 ± 8). Patient satisfaction had a mean of 8 ± 2 (range, 1-10) and median of 10.

CONCLUSION

The return-to-competition rate in elite skiers and snowboarders after hip arthroscopy for FAI was 85% at an average of 8.9 months and with a career length of 3.6 years after surgery. Significant improvement in PROs was demonstrated for the HOS-Activities of Daily Living, HOS-Sport Specific Subscale, modified Harris Hip Score, and 12-Item Short Form Health Survey Physical Component Summary, with a median patient satisfaction score of 10. These findings support hip arthroscopy as an effective procedure for the treatment of FAI in elite skiers and snowboarders with symptomatic activity-limiting hip pain, allowing them to return to their previous levels of competition at a high rate.

Incidence of heterotopic ossification following hip arthroscopy is low: considerations for routine prophylaxis

PURPOSE

This scoping review aims to map and summarise the available literature on heterotopic ossification (HO) following hip arthroscopy, with particular focus on incidence, distribution as per Brooker classification, efficacy of prophylactic measures and factors that may influence the likelihood of production of HO.

METHODS

A computer-based search was performed on PubMed, Embase, Emcare, Cinahl, ISI web of science and Scopus using the terms 'heterotopic ossification' and 'hip arthroscopy'. Articles reporting heterotopic ossification following hip arthroscopy for any condition were included after two-stage title/abstract and full-text screening.

RESULTS

Of the 663 articles retrieved, 45 studies were included. The proportion of patients with HO ranged from 0 to 44%. The majority of the cases were either Brooker grade I or II. Of the six studies investigating the effect of NSAID prophylaxis, five reported a significantly lower incidence of heterotopic ossification associated with its use. Weak evidence suggests that an outside-in arthroscopic approach, no capsular closure, male sex and mixed cam and pincer resection may be associated with an increased risk of HO.

CONCLUSION

Although there is a large variation in rates of HO following hip arthroscopy in the current literature, the majority of studies report a low incidence. Evidence exists advocating the administration of post-operative NSAIDs to reduce the incidence of HO following hip arthroscopy. This, combined with the low risk of complications, means there is a favourable risk-benefit ratio for prophylactic NSAID used in HA. Future research should work to identify patient clinical and demographic factors which may increase the risk of development of HO, allowing clinicians to risk stratify and select only specific patients who would benefit from receiving NSAID prophylaxis.

Epidemiology and Outcomes of Maxillofacial Injuries in NCAA Division I Athletes Participating in 13 Sports

Background:

Maxillofacial injuries account for an estimated 11% of National Collegiate Athletic Association (NCAA) sport-related injuries and occur at a rate of 0.2-1.5 injuries per 1000 athletic events/exposures.

Purpose:

The purpose of this study was to report the epidemiology, treatment, and outcomes of maxillofacial injuries in NCAA Division I athletes participating in 13 sports. It was hypothesized that the rate of maxillofacial injuries would be greater than previously reported in national registry studies.

Study Design:

Descriptive epidemiology study.

Methods:

A single-institution registry was utilized to retrieve the maxillofacial injuries and surgical procedures recorded over 4 athletic seasons, for the years 2015 through 2019, across 13 NCAA Division I sports. The incidence of injuries per sport was reported as the number per 1000 athlete-exposure (AE) hours. The time lost from participation and time to complete injury resolution per sport were reported as the mean and range.

Results:

A total of 193 maxillofacial injuries occurred over 4 seasons. The overall incidence of maxillofacial injuries was 2.06 injuries per 1000 AE hours. The injury incidence for male and female athletes was 1.92 and 2.43 injuries per 1000 AE hours, respectively. Men’s basketball (8.30 injuries per 1000 AE hours) and men’s water polo (8.15 injuries per 1000 AE hours) had the highest rates of all sports. Overall, 20 athletes (10.4%) required surgery. The mean time to resolution across all sports was 33.3 days (range, 0-336 days) per injury. The mean time lost across all sports was 17.1 days (range, 0-336 days) per injury.

Conclusion:

At a single NCAA Division I institution, maxillofacial injuries occurred at a higher rate than previously thought and could lead to significant time lost from sport participation. Basketball players were at the highest risk of this injury. Across all sports, male athletes took longer to return to sport after a maxillofacial injury compared to female athletes, but the latter required more time to fully recover. Maxillofacial injuries may require surgical treatment, and their prevention is critical.

Do Relaxin Levels Impact Hip Injury Incidence in Women? A Scoping Review

Purpose

The aim of this review is to assess the current evidence regarding the impact of relaxin on incidence of soft tissue hip injuries in women.

Methods

A trained research librarian assisted with searches of PubMed, Embase, CINAHL, and SPORTDiscus, with a preset English language filter. The review was completed per the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis methodology. Included studies required assessment of relaxin effects on musculoskeletal health, pelvic girdle stability, or hip joint structures in human subjects. Letters, texts, and opinion papers were excluded.

Results

Our screen yielded 82 studies. Molecularly, relaxin activates matrix metalloproteinases (MMPs) including collagenases MMP-1/-13 and gelatinases MMP-2/-9 to loosen pelvic ligaments for parturition. However, relaxin receptors have also been detected in female periarticular tissues, such as the anterior cruciate ligament, which tears significantly more often during the menstrual cycle peak of relaxin. Recently, high concentrations of relaxin-activated MMP-9 receptors have been found on the acetabular labrum; their expression upregulated by estrogen.

Conclusions

Menstrual cycle peaks of relaxin activate MMPs, which locally degrade collagen and gelatine. Women have relaxin receptors in multiple joints including the hip and knee, and increased relaxin correlates with increased musculoskeletal injuries. Relaxin has paracrine effects in the female pelvis on ligaments adjacent to hip structures, such as acetabular labral cells which express high levels of relaxin-targeted MMPs. Therefore, it is imperative to investigate the effect of relaxin on the hip to determine if increased levels of relaxin are associated with an increased risk of acetabular labral tears.

Association Between Comorbid Depression and Rates of Postoperative Complications, Readmissions, and Revision Arthroscopic Procedures After Elective Hip Arthroscopy

Background:

Depression and related psychiatric diagnoses are common in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). The effects of depression on postoperative complications, readmissions, and additional ipsilateral hip surgery are not well studied.

Hypothesis:

Patients with preoperative depression who undergo hip arthroscopy for FAIS would experience higher rates of 90-day postoperative complications and readmissions, with an increased risk of additional ipsilateral hip procedures, as compared with patients without depression.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A retrospective cohort study between 2010 and 2019 was performed using the Mariner/PearlDiver database. Current Procedural Terminology and International Classification of Diseases codes were used to compare patients with and without preexisting depression who underwent hip arthroscopy for FAIS. Patients were matched at a 1:1 ratio based on age, sex, Charlson Comorbidity Index, body mass index, and tobacco use. Patients undergoing shoulder or knee arthroscopy were also identified to compare lifetime preoperative depression prevalence amongst groups.

Results:

The lifetime preoperative depression prevalence was significantly higher in patients undergoing hip arthroscopy as compared with patients undergoing shoulder or knee arthroscopy (25.4% vs 22.2% vs 19.8%; P < .001). When compared with the patients without depression, patients with preoperative depression had higher rates of 90-day readmissions (2.4% vs 1.5%) and complications, including urinary tract infection (36.2% vs 28.9%), pneumonia (12.9% vs 9.1%), hematoma formation (3.1% vs 1.9%), acute kidney injury (4.0% vs 2.6%), deep venous thrombosis/pulmonary embolism (2.6% vs 1.7%), and superficial infection (4.9% vs 2.8%; P < .01 for all comparisons). Preoperative depression was associated with significantly higher odds of undergoing revision hip arthroscopy within 2 years (6.3% vs 2.4%; P < .001).

Conclusion:

Patients with preexisting depression experienced higher rates of 90-day postoperative complications and hospital readmissions after elective hip arthroscopy for FAIS and were more likely to undergo revision hip arthroscopy within 2 years of the index procedure.
