Comparison of post-operative outcomes following anterior cruciate ligament reconstruction between patients with vs. without elevated tibial tubercle-trochlear groove (TT-TG) distance.

PURPOSE: It is unclear if an elevated tibial tubercle-trochlear groove (TT-TG) distance is a risk factor for poor outcomes following ACLR. Therefore, the purpose of this study was to determine whether patients with an elevated TT-TG have an increased risk of retear following primary ACLR compared to controls with a normal TT-TG. METHODS: All patients who underwent primary ACLR between July 2018 and June 2019 with an available preoperative magnetic resonance imaging (MRI) were eligible for inclusion. TT-TG distance was measured on preoperative MRI scans by two independent investigators. Clinical outcomes, return-to-sport rates, and Lysholm scores were compared between patients with a TT-TG < 12.5 mm (normal) and those with a TT-TG ≥ 12.5 mm (elevated). RESULTS: Overall, 159 patients were included, 98 with normal TT-TG distance and 61 with elevated TT-TG distance. Patients with an elevated TT-TG distance had worse post-operative Lysholm scores than patients with a normal TT-TG distance (83.0 vs. 95.0, p = 0.010). In patients who received a bone-patellar tendon-bone (BTB) graft, an elevated TT-TG distance was associated with higher rates of subjective instability (13.0% vs. 3.0%, p = 0.041), reoperation (13.0% vs. 1.5%, p = 0.012), and post-operative complications (25.0% vs. 8.2%, p = 0.026), as well as lower ACL psychological readiness scores (324.1 vs. 446.7, p = 0.015). CONCLUSION: Patients with an elevated pre-operative TT-TG distance have worse Lysholm scores than patients with normal TT-TG distance. Patients with an elevated pre-operative TT-TG distance who underwent ACLR with BTB grafts had significantly higher rates of subjective instability, reoperation, and post-operative complications. LEVEL OF EVIDENCE: III.

Increased rates of subjective shoulder instability after Bankart repair with remplissage compared to Latarjet surgery.

HYPOTHESIS AND BACKGROUND: Controversy exists as to the ideal management of young active patients with subcritical glenoid bone loss and an off-track Hill-Sachs lesion, and the Latarjet and arthroscopic Bankart with remplissage are effective surgical options. The purpose of this study was to compare rates of recurrent instability and reoperation, as well as patient-reported outcome measures, between Latarjet and arthroscopic Bankart repair with remplissage surgery patients. The authors hypothesized that there would be no difference in rates of recurrent instability, reoperation, and postoperative outcomes between patients who underwent Latarjet surgery and patients who underwent Bankart repair with concomitant remplissage postoperatively. MATERIALS AND METHODS: All patients who underwent primary shoulder stabilization for shoulder instability from 2014 to 2019 were screened. Latarjet and Bankart repair with remplissage patients were included if arthroscopic surgery was performed in response to anterior shoulder instability. Recurrent instability, revision, shoulder range of motion, return to sport (RTS), and patient-reported outcome measures (Oxford Shoulder Instability, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form scores) were compared between groups. RESULTS: Overall, 43 Latarjet patients (age: 29.8 ± 12.1 years, 36 males 7 females) and 28 Bankart repair with remplissage patients (age: 28.2 ± 8.8 years, 25 males 3 females) were included with a mean follow-up of 3.3 ± 1.9 years. Patients who underwent Latarjet surgery had larger amounts of bone loss (19% vs. 11%, P < .001), a lower rate of off-track Hill-Sachs lesions (47% vs. 82%, P < .001), and more frequently had a history of chronic shoulder dislocations (88% vs. 43%, P < .001) compared to Bankart repair with remplissage patients. Latarjet patients less frequently reported feeling subjective shoulder instability after surgery (21% vs. 50%, P = .022), which was defined as feeling apprehension or experiencing a shoulder subluxation or dislocation event. There were no differences in rates of postoperative dislocation, revision, reoperation, or RTS, as well as patient-reported outcome scores, between groups (all P > .05). CONCLUSION: Despite differences in osseous defects, Latarjet and Bankart repair with remplissage patients had similar rates of clinical, patient-reported, and RTS outcomes at a mean of 3.3 years postoperatively. Latarjet surgery patients may be less likely to experience subjective shoulder instability postoperatively than patients who undergo Bankart repair with concomitant remplissage.

The Arthroscopic Surgery Skill Evaluation Tool Global Rating Scale is a Valid and Reliable Adjunct Measure of Performance on a Virtual Reality Simulator for Hip Arthroscopy.

PURPOSE: The purpose of this study is to further evaluate the construct validity and interobserver reliability of a hip arthroscopy virtual simulator using the Arthroscopic Surgery Skill Evaluation Tool (ASSET) global rating scale. METHODS: Thirty participants (23 male/7 female) completed a diagnostic arthroscopy and a loose body retrieval simulation on the VirtaMed Arthros Hip Simulator (Zurich, Switzerland) twice at a minimum of 1 week apart. Subjects consisted of 12 novices (medical students, postgraduate year [PGY] 1-2), 5 intermediate trainees (PGY3-4), 9 senior trainees (PGY5 and fellows), and 4 attending faculty. Simulator metrics were recorded and then compiled to generate a total simulator score (TSS). The loose body retrieval was graded using the ASSET scoring tool. Inter-rater and intrarater reliability for the ASSET for 2 blinded raters and construct validity of the ASSET and the TSS were calculated. Correlation between the TSS, ASSET and individual simulator metrics was determined. RESULTS: Prior simulation experience (P ≤ 0.01) correlated with higher TSS and higher ASSET, while video game experience correlated with higher TSS on the diagnostic module only (P = 0.004). There was a significant difference in ASSET score among all experience groups (P < 0.04). Novices had the lowest mean ASSET whereas experts had the highest mean ASSET with a difference of 17.4 points. Overall performance on the surgical module significantly correlated with the ASSET score (r = 0.444, P = 0.016). There was a significant positive correlation among higher ASSET and number of loose bodies retrieved, operation time, camera path and grasper path length, and percentage of cartilage injury. ASSET demonstrated excellent intrarater reliability and showed substantial or better inter-reliability in 8 of 9 domains. CONCLUSION: The VirtaMed hip arthroscopy simulator demonstrated good construct validity and excellent reliability for simulator-based metrics and ASSET score. Use of both simulator metrics and ASSET offers a more comprehensive performance assessment on hip arthroscopy simulation than either measure alone. CLINICAL RELEVANCE: As virtual reality simulation for arthroscopy becomes more commonplace in orthopaedic training, evaluation of the most effective objective and subjective measures of performance is necessary to optimize simulation training.

Injuries in the emerging sport of roundnet (Spikeball): a cross-sectional study of 166 players.

Objectives: To describe injury frequency and characteristics in roundnet athletes and compare injury characteristics between elite and non-elite athletes. Methods: This cross-sectional study was performed by convenience sampling recreational and competitive roundnet athletes via a REDCap survey distributed through social media platforms. The custom survey evaluated athlete demographics, past sport participation, training workload and roundnet-related injuries throughout their whole playing career. Injury characteristics were reported for the full study cohort and compared between elite and non-elite athletes. Results: 166 athletes participated in the study, with 33.7% playing at the elite level. 279 injuries were reported, with 86.1% (n=143) of athletes reporting at least one injury throughout their playing career. Injuries most frequently involved the shoulder (20%), ankle (18%), knee (14%) and elbow (14%). 47% of reported injuries occurred due to overuse, and 67% resulted in missed competition time averaging 2.0 months. There were 10 injuries (3.6%) that required surgery. No differences were found in regards to injury frequency (1.9±1.5 vs 1.6±1.1 injuries per athlete, p=0.159) or any injury characteristics between elite and non-elite athletes. Conclusion: Roundnet athletes experienced a mean of 1.7±1.2 injuries while playing roundnet. Injuries most frequently involved the shoulder and ankle and often resulted in missed competition time. The level of competition does not significantly impact injury frequency or characteristics. Roundnet athletes may benefit from injury prevention programmes that include shoulder strengthening, maintaining shoulder range of motion and ankle stability.

Evaluating Return to Sports After Surgical Treatment of Unstable Osteochondritis Dissecans of the Knee: A Systematic Review.

Background: Although the incidence of osteochondritis dissecans (OCD) of the knee may be low, an overview and comparison of sports-related outcomes with current surgical management techniques are needed. Purpose: To summarize the available evidence regarding outcomes for different surgical treatment options for unstable OCD of the knee in both skeletally mature and immature patients by calculating the return to sports (RTS) rate, the mean RTS time, and other sports-related postoperative outcome measures. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of studies on RTS after surgical correction of unstable OCD within the knee was conducted utilizing PubMed, Embase, and the Cochrane databases. Included were studies discussing the treatment of unstable OCD with minimum 1-year follow-up outcomes. Multivariate analysis was used to compare studies grouped together based on RTS and skeletal maturity. Results: Of 2229 articles, 6 studies (197 patients; 198 knees) met the inclusion criteria and were included in our analysis. The percentage of patients who returned to the previous level of sport ranged from 52% to 100%; those returning to any level of sport ranged from 87% to 100%. Clinical outcomes did not differ between patients with open versus closed physes. Osteochondral Autograft Transfer System (OATS) procedures had a 100% RTS rate across several studies with skeletally mature and mixed cohorts, and microfracture had the lowest overall RTS rate (52%). For skeletally immature patients, all examined studies that utilized either open or arthroscopic reduction and internal fixation, 77% and 78%, respectively, had acceptable RTS rates. Arthroscopic fixation had a higher rate of revision surgery in both skeletally mature and immature patients. Conclusion: Our analysis indicated that the treatment of unstable OCD lesions using the OATS technique demonstrated high RTS rates across several studies, while microfracture alone exhibited the lowest RTS rate. Both arthroscopic and open internal fixation utilizing bioabsorbable screws yielded satisfactory RTS rates for juvenile patients with OCD.

Rates of Reporting and Analyzing Race and Ethnicity in Athlete-Specific Sports Medicine Research: A Systematic Review.

Background: Race- and ethnicity-based differences in treatment access and outcomes have been reported in the orthopaedic sports medicine literature. However, the rate at which race and ethnicity are reported and incorporated into the statistical analysis of sports medicine studies remains unclear. Purpose: To determine the rate at which race and ethnicity are reported and analyzed in athlete-specific sports medicine literature. Study Design: Systematic review; Level of evidence, 4. Methods: Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, articles published by the 3 journals of the American Orthopaedic Society for Sports Medicine between 2017 and 2021 were considered for inclusion. Original sports medicine research studies that focused on athletes were included. Outcome measures included reporting and analysis of patient demographics (age, sex, race, ethnicity). Studies that included demographic variables in a multivariate analysis or that performed a race-/ethnicity-based stratified analyses were considered to have analyzed that variable. Studies that reported and/or analyzed patient demographics were examined. Chi-square tests were performed to determine statistical significance. Results: A total of 5140 publications were screened, and 842 met the inclusion criteria. Age and sex were well reported (84.1% and 87.0%, respectively), while race (3.8%) and ethnicity (2.0%) were poorly reported. There was no difference in rates of reporting age, sex, race, or ethnicity between the American Journal of Sports Medicine (AJSM), the Orthopaedic Journal of Sports Medicine (OJSM), or Sports Health: A Multidisciplinary Approach (Sports Health). The rate of analysis was also calculated as a percentage of the studies that reported that variable. Of the studies that reported age, 38.5% analyzed age. Using this method, 26.2% of studies analyzed sex, 40.6% analyzed race, and 17.6% analyzed ethnicity. Although there was no difference in the overall rate at which studies from the 3 journals analyzed ethnicity, Sports Health studies analyzed age (P = .044), sex (P = .001), and race (P = .027) more frequently than studies published in AJSM and OJSM. Of the studies that analyzed race, most of those studies (8/13, 61.5%) found significant race-based differences in reported outcomes. Conclusion: This systematic review demonstrated that race and ethnicity are poorly reported and analyzed in athlete-specific sports medicine literature, despite the fact that a majority of studies analyzing race found significant differences between racial groups. Improved reporting of race and ethnicity can determine whether race- and ethnicity-based differences exist in patient interventions to ameliorate disparities in patient outcomes.

Female Authorship Is Driving Studies of Female Athletes: A Systematic Review.

BACKGROUND: Patient sex is known to affect patient outcomes in sports medicine. Historically, many studies on athletes have focused on male athletes and been generalized to female athletes. HYPOTHESIS: Studies with female first or senior authors will isolate female athletes as study participants more frequently than studies with male first or senior authors. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocols, original research studies published between 2017 and 2021 that analyzed athletes were systematically screened from the 6 top sports medicine journals (British Journal of Sports Medicine; Arthroscopy: The Journal of Arthroscopic and Related Surgery; Knee Surgery, Sports Traumatology, Arthroscopy; American Journal of Sports Medicine; Orthopaedic Journal of Sports Medicine; Sports Health: A Multidisciplinary Approach). Articles were included for analysis if they met the following criteria: (1) original sports medicine research study, (2) analysis involving athletes, and (3) inclusion of ≥10 participants. Exclusion criteria included (1) review articles of any type and (2) cadaveric studies. The determination of author sex was completed using the name-to-gender assignment algorithm Genderize.io (https://genderize.io/). RESULTS: A total of 1146 studies were included in quantitative analysis. There were 246 studies with a female first author (21.5%) and 191 studies with a female senior author (16.7%). When looking at all authors (first, senior, and intermediate), 19.9% were female. Female first authors were over 4 times more likely to isolate female athletes in clinical research than male first authors (17.5% vs 3.8%, respectively; P < .001). Female senior authors were approximately twice as likely to isolate female athletes compared with male senior authors (11.5% vs 5.8%, respectively; P < .001). CONCLUSION: Female first authors were significantly more likely to perform research isolating female athletes. While improving the frequency of female athlete research is multifactorial, increasing the number of female researchers may have a direct effect on improving gender equality in sports medicine research.

How to Be a Mentee: Getting the Most of Your Mentorship.

Mentorship is a key part of the development of knowledge and skills in orthopedics. Mentorship at each of these different phases is important to preparing and enabling a competent, knowledgeable, and well-rounded surgeon. Although the mentor is generally the one in a senior position, experienced in their field, the mentee is the protégé or the trainee engaged in a relationship with the person with expertise. There should be mutual responsibility on both sides to develop a collaborative relationship in order to optimize value in the relationship for both parties.

Republication of "Open Repair of Acute Achilles Tendon Ruptures: Is the Incidence of Clinically Significant Wound Complications Overestimated?"

Background: Conflicting evidence exists regarding the optimal management of acute Achilles tendon ruptures. Operative repair is thought to afford patients a lower risk of rerupture, albeit at a higher overall risk of wound complications. Methods: A retrospective chart review of 369 consecutive patients undergoing open repair of acute Achilles tendon ruptures performed by a single foot and ankle fellowship-trained orthopedic surgeon was undertaken. Healing was classified as no complications, complications without prolonging treatment, complications requiring prolonged local treatment, and complications requiring operative intervention. A statistical analysis comparing the rates of complications in this cohort to that reported in the literature was conducted. Results: There were a total of 33 (8.94%) wound complications. Compared to the rates reported in the literature, no significant difference was detected (P = .3943; CI 6.24-12.33). However, when the complications not requiring additional treatment or prolonged care were excluded, only 9 wound complications (2.44%) were identified-a significantly lower complication rate than that reported in the literature (P < .0001; CI 1.12-4.58). There were only 2 (0.54%) major complications requiring operative intervention, also a significantly lower rate than in the literature (P < .0001; CI 0.067-1.94). Conclusion: In the past, wound-healing complications have been cited as a concern when treating patients operatively. We found that when solely looking at healing complications prolonging the patients' overall recovery, a significantly lower rate of complications existed compared to that reported in the literature. Level of Evidence: Level IV.

Differences in the Severity and Location of Patellofemoral Cartilage Damage Between Instability Patients With and Without Patella Alta.

Background: Patella alta is a risk factor for recurrent patellar instability. Differences in chondral injury in patients with patellar instability between patella alta and patella norma have not been evaluated. Purpose: To analyze whether preoperative cartilage damage differs in severity and location between patellar instability patients with and without patella alta. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with patellar instability who underwent patellar realignment surgery at a single institution with preoperative magnetic resonance imaging (MRI) scans were included. After measurement of Caton-Deschamps index (CDI) on MRI, patients were divided into patella alta (CDI ≥1.3) and patella norma groups. The area measurement and depth and underlying structures (AMADEUS) score was used to quantify cartilage defect severity on MRI. Results: A total of 121 patients were divided into patella alta (n = 50) and patella norma (n = 71) groups. The groups did not differ significantly in sex ratio, age at MRI, body mass index, mean reported number of previous dislocations, or mean interval between first reported dislocation and date of MRI. A total of 34 (68%) of the patella alta group and 44 (62%) of the patella norma group had chondral defects (P = .625) with no significant between-group differences in defect size (P = .419). In both groups, chondral injuries most affected the medial patellar facet (55% in patella alta vs 52% in patella norma), followed by the lateral facet (25% vs 18%), and lateral femoral condyle (10% vs 14%). A smaller proportion of patients had full-thickness defects in the patella alta compared with the patella norma group (60% vs 82%; P = .030). The overall AMADEUS score was higher for the patella alta versus the patella norma group (68.9 vs 62.1; P = .023), indicating superior articular cartilage status. Conclusion: Patients with patella alta had less severe cartilage injury after patellar instability, including a lower proportion with full-thickness defects and better overall cartilage grade. The location of injury when present was similar between alta and norma, with most defects affecting the medial facet, lateral facet, and lateral femoral condyle in descending frequency.

Inequalities in the Evaluation of Male Versus Female Athletes in Sports Medicine Research: A Systematic Review.

BACKGROUND: Female sports participation continues to rise; however, inequalities between male and female athletes still exist in many areas and may extend into medical research. PURPOSE: The purpose of this study was to (1) compare the number of published studies evaluating male versus female athletes in various sports and (2) identify which co-ed sports currently underrepresent female athletes in the sports medicine literature. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: All nonreview research studies published from 2017 to 2021 in 6 top sports medicine journals were considered for inclusion. Sports medicine studies were included that isolated athletes, reported study outcomes specific to male and/or female patients, provided study outcomes for specific sports, and evaluated ≤3 different sports. The total number of studies reporting on male and/or female athletes were compared for all sports, and odds ratios (ORs) were calculated. Comparisons of study design, level of sports participation, outcomes assessed, and study quality were also made according to participant sex. RESULTS: Overall, 669 studies were included the systematic review. Most studies isolated male athletes (70.7%), while 8.8% isolated female athletes and 20.5% included male and female athletes. Female athletes were more frequently studied in softball and volleyball, while male athletes were more commonly researched in baseball, soccer, American football, basketball, rugby, hockey, and Australian football. Notably, male athletes were largely favored in baseball/softball (91% vs 5%; OR = 18.2), rugby (72% vs 5%; OR = 14.4), soccer (65% vs 15%; OR = 4.3), and basketball (58% vs 18%; OR = 3.2). CONCLUSION: Sports medicine research has favored the evaluation of male athletes in most sports, including the majority of co-ed sports. Potential reasons for this inequality of research evaluation include availability of public data and database data, financial and promotional incentives, a high percentage of male sports medicine clinicians and researchers, and sex biases in sport. While the causes of these differences are multifaceted, researchers should consider both sexes for study inclusion whenever possible, and journals should support a more balanced representation of research publications regarding male and female athletes.

Rates of Reporting and Analyzing Patient Sex in Sports Medicine Research: A Systematic Review.

BACKGROUND: Sex differences in sports medicine are well documented. However, no studies to date have reviewed the rate at which sex is reported and analyzed in the athlete-specific orthopaedic sports medicine literature. PURPOSE: To determine the rates of reporting and analyzing patient sex in athlete-specific sports medicine literature. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Articles published by the 3 journals of the AOSSM (American Journal of Sports Medicine [AJSM], Orthopaedic Journal of Sports Medicine, and Sports Health: A Multidisciplinary Approach) between 2017 and 2021 were considered for inclusion. Original sports medicine research studies that isolated athletes were included. Studies that isolated sports that are predominantly single sex at the college and/or professional levels (football, baseball, softball, and wrestling) were excluded. RESULTS: Of the 5140 publications screened, 559 met the inclusion criteria. In total, 93.9% of all studies reported patient sex, and 34.7% of all studies analyzed patient sex. However, 143 studies only included males and 50 studies only included females (n = 193). When excluding these single-sex studies, analysis of the remaining 366 studies found that the rate of sex-specific analysis increased to 53.0%. Rates of reporting patient sex did not significantly differ by journal or by year. Similarly, rates of analyzing patient sex did not differ by year, but Sports Health analyzed sex the most frequently, and AJSM analyzed sex the least frequently (P = .002). Studies that isolated college (84.1%), youth (66.7%), or recreational (52.6%) athletes analyzed sex at or above the overall rate of 53.0%, but studies of elite athletes (35.7%) tended to analyze sex less frequently. CONCLUSION: Patient sex is well reported in the athlete-specific sports medicine literature (93.9% of included studies reported sex), demonstrating that most studies include sex as a demographic variable. However, patient sex was analyzed only in 53.0% of studies that included both male and female patients. Given that athlete-specific sex differences are known to exist within the field of sports medicine, many studies that could benefit from using patient sex as a variable for analysis likely fail to do so.

Prior Acromioplasty Provides Similar Outcomes and Rate of Postoperative Complications Including Acromial Fracture After Reverse Total Shoulder Arthroplasty: A Retrospective Matched-Cohort Analysis.

Purpose: To compare outcomes of reverse total shoulder arthroplasty (RTSA) in patients with prior arthroscopic acromioplasty versus a control group of patients with no history of acromioplasty. Methods: We performed a retrospective matched-cohort study of patients from a single institution who underwent RTSA with a history of acromioplasty from 2009 to 2017 with a minimum 2-year follow-up period. Patients' clinical outcomes were evaluated using the American Shoulder and Elbow Surgeons shoulder score and Simple Shoulder Test, visual analog scale, and Single Assessment Numeric Evaluation surveys. Postoperative radiographs and patient charts were reviewed to determine whether patients sustained a postoperative acromial fracture. Charts were reviewed to determine range of motion and postoperative complications. Patients were matched on a 1:1 basis to a cohort of patients who underwent RTSA without a history of acromioplasty, and comparisons were performed using t and χ2 tests. Results: Forty-five patients who underwent RTSA with a history of acromioplasty met the inclusion criteria and completed the outcome surveys. There were no significant differences between cases and controls in post-RTSA American Shoulder and Elbow Surgeons, visual analog scale, Simple Shoulder Test, or Single Assessment Numeric Evaluation outcome scores. There was no difference in the postoperative acromial fracture rate between cases and controls (P = .577). Overall, more complications occurred in the study group (n = 6, 13.3%) compared with the control group (n = 4, 8.9%); however, this difference was not statistically significant (P = .737). Conclusions: After RTSA, patients who have undergone a prior acromioplasty have similar functional outcomes without a significant difference in the rate of postoperative complications compared with patients with no history of acromioplasty. Furthermore, previous acromioplasty does not increase the risk of acromial fracture after RTSA. Level of Evidence: Level III, retrospective comparative study.

Bankart Repair With or Without Concomitant Remplissage Results in Similar Shoulder Motion and Postoperative Outcomes in the Treatment of Shoulder Instability.

Purpose: To compare the results of patients who underwent Bankart repair with or without concomitant remplissage for treatment of shoulder instability. Methods: All patients who underwent shoulder stabilization for shoulder instability from 2014 to 2019 were evaluated. Patients who underwent remplissage were matched to those patients who received no remplissage based on sex, age, body mass index, and date of surgery. Glenoid bone loss and presence of an engaging Hill-Sachs lesion were quantified by 2 independent investigators. Postoperative complications, recurrent instability, revision, shoulder range of motion (ROM), return to sport (RTS), and patient-reported outcome measures (Oxford Shoulder Instability, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons scores) were compared between groups. Results: Overall, 31 patients who underwent remplissage were identified and matched to 31 patients who received no remplissage at a mean follow-up of 2.8 ± 1.8 years. Glenoid bone loss was similar between groups (11% vs 11%, P = .956); however, engaging Hill-Sachs lesions were more prevalent in the patients who underwent remplissage than the patients who received no remplissage (84% vs 3%, P < .001). There were no significant differences in rates of redislocation (remplissage: 12.9% vs no remplissage: 9.7%), subjective instability (45.2% vs 25.8%), reoperation (12.9% vs 0%), or revision (12.9% vs 0%) between groups (all P > .05). Also, there were no differences in RTS rates, shoulder range of motion, or patient-reported outcome measures (all P > .05). Conclusions: If a patient is indicated for Bankart repair with concomitant remplissage, surgeons may expect shoulder motion and postoperative outcomes similar to those of patients without engaging Hill-Sachs lesions who undergo Bankart repair without concomitant remplissage. Level of Evidence: Therapeutic case series, level IV.

Preoperative Patella Alta on Caton-Deschamps Index Is a Predictor of Outcome Following Isolated Medial Patellofemoral Ligament Reconstruction.

Purpose: The purpose of this study was to determine whether a preoperative Caton-Deschamps index (CDI) ≥ 1.30, as measured by magnetic resonance imaging, is associated with rates of postoperative instability, revision knee surgery, and patient-reported outcomes in patients undergoing isolated medial patellofemoral ligament (MPFL) reconstruction. Methods: Patients who underwent primary medial patellofemoral ligament reconstruction (MPFLR) between 2015 and 2019 at a single institution were assessed. Only those with at least 2 year follow up were included. Patients who had undergone a previous ipsilateral knee surgery, concomitant tibial tubercle osteotomy and/or ligamentous repair/reconstruction at the time of MPFL reconstruction were excluded from the study. CDIs were evaluated by three investigators based on magnetic resonance imaging measurement. Patients with a CDI ≥ 1.30 were included in the patella alta group, while those with a CDI between 0.70 and 1.29 served as controls. A retrospective review of clinical notes was used to evaluate the number of postoperative instability episodes and revisions. Functional outcomes were measured by the International Knee Documentation Committee (IKDC) and 12-Item Short Form Health Survey (SF-12) physical and mental scores. Results: Overall, 49 patients (50 knees, 29 males, 59.2%) underwent isolated MPFLR. Nineteen (38.8%) patients had a CDI ≥ 1.30 (mean: 1.41, range: 1.30-1.66). The patella alta group was significantly more likely to experience a postoperative instability episode (36.8% vs 10.0%; P = .023) and was more likely to return to the operating room for any reason (26.3% vs 3.0%; P = .022) compared to those with normal patellar height. Despite this, the patella alta group had significantly greater postoperative IKDC (86.5 vs 72.4; P = .035) and SF-12 physical (54.2 vs 46.5; P = .006) scores. Pearson's correlation showed a significant association between CDI and postoperative IKDC (R 2 = 0.157; P = .022) and SF-12P (R 2 = .246; P = .002) scores. There was no difference in postoperative Lysholm (87.9 vs 85.1; P = .531). and SF-12M (48.9 vs 52.5; P = .425) scores between the groups. Conclusion: Patients with preoperative patella alta, as measured by CDI had higher rates of postoperative instability and return to the OR with isolated MPFL reconstruction for patellar instability. Despite this, higher preoperative CDI was associated with greater postoperative IKDC scores and SF-12 physical scores in these patients. Level of Evidence: Retrospective cohort study, Level IV.

Multidirectional instability in female athletes.

Multidirectional instability (MDI) of the shoulder is characterized by generalized shoulder capsular laxity and symptomatic shoulder instability in more than one direction with one direction of instability as inferior. Generalized ligamentous laxity and specifically shoulder laxity, has been associated with female athletes. While males are at a higher risk of shoulder instability due to a number of extrinsic risk factors including participation in higher risk contact/collision activities, females are particularly susceptible to MDI due to their association with increased joint laxity. Patients with MDI often have a loose patulous capsule and display altered glenohumeral and scapulothoracic mechanics. The mainstay of treatment is physical therapy focusing on strengthening the dynamic stabilizers of the shoulder. In cases of failed rehabilitation, operative management most frequently includes either open or arthroscopic capsular shift with reasonably good outcomes and return to sport. Sex-related differences concerning shoulder instability risk and pathophysiology may influence treatment decisions and outcome measures. An understanding of the factors concerning shoulder instability specific to the female athlete is important in management and prevention of injury.

Discrepancies in Work-Family Integration Between Female and Male Orthopaedic Surgeons.

BACKGROUND: Female surgeons, representing 6.5% of the American Academy of Orthopaedic Surgeons, are particularly vulnerable to work-family conflict. This conflict may deter women from considering orthopaedic surgery as a specialty. The study objective was to identify differences in work-family integration between female and male orthopaedic surgeons in the United States. METHODS: An anonymous survey collecting data within the domains of work, family, and satisfaction was completed by 347 orthopaedic surgeons (153 female, 194 male). Differences in responses between males and females were identified. RESULTS: Female surgeons were younger than males (mean, 41.1 versus 50.1 years; p < 0.001) and earlier in their careers, with 60.3% of males in practice >10 years compared with 26.1% of females (p < 0.001). Consulting (7.8% versus 31.4%; p < 0.001), course faculty positions (19.0% versus 39.2%; p < 0.001), and academic and leadership titles (30.7% versus 47.4%; p = 0.002) were significantly less common among females. There was a significant income disparity between females (mean yearly income, $300,000 to $400,000) and males (mean, $400,000 to $500,000; p < 0.001). Females were more likely to have never married (12.4% versus 2.6%; p < 0.001), or they married at a later mean age (30.2 ± 4.7 versus 28.3 ± 3.9 years; p < 0.001). Females were more likely to have no children (29.4% versus 7.8%; p < 0.001), require fertility treatment (32.0% versus 11.9%; p < 0.001), and not have children until after completing their medical training (63.0% versus 31.1%; p < 0.001). Female surgeons reported more responsibility in parenting (p < 0.001) and household duties (p < 0.001) than males. Work-family balance satisfaction was 72.3% in females and 82.1% in males (p = 0.081). CONCLUSIONS: This study highlights deficiencies in work-family integration that appear to uniquely impact female orthopaedic surgeons. Female surgeons delay starting a family, more frequently require fertility treatments, carry more responsibility at home, have fewer academic and leadership roles, earn lower incomes, and are less satisfied with work-family balance relative to males. The discrepancy in work-family integration must be addressed to attract, support, and retain women as successful orthopaedic surgeons.

Beach Chair Versus Lateral Decubitus Surgical Positioning for Arthroscopic Anterior Shoulder Stabilization: A Retrospective Comparison of Clinical and Patient-Reported Outcomes.

Background: Surgical positioning can affect both perioperative and postoperative complication rates. It is unclear whether beach-chair versus lateral decubitus positioning affects outcomes in patients undergoing arthroscopic anterior shoulder stabilization surgery. Purpose: The purpose of this study was to compare recurrent instability, complications, and patient-reported outcomes between patients who underwent arthroscopic anterior shoulder stabilization in the beach-chair versus the lateral decubitus positions. It was hypothesized that recurrent instability, complications, and patient-reported outcomes would not be affected by surgical positioning. Study Design: Cohort study; Level of evidence, 3. Methods: The authors reviewed the medical records of patients who underwent shoulder stabilization (Current Procedural Terminology codes 29806 and 29807) from 2015 to 2019. Patients were included only if anterior instability was confirmed, arthroscopic surgery was performed in response to shoulder instability, and a minimum of 2 years of follow-up data were available. Data collected for eligible patients included perioperative and postoperative complications, recurrent instability, reoperation, and revision. Patients also completed surveys for the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, Oxford Shoulder Instability (OSI) score, and a return to any level of sport (RTS) questionnaire. Results: Overall, 294 patients (162 lateral decubitus and 132 beach-chair positions) were included, with an average follow-up of 2.4 ± 1.6 years. There were no significant differences in demographics between groups, nor were there differences in the rates of postoperative dislocations, subjective instability, reoperations, revisions, or complications. There was a trend toward a higher revision rate in the beach-chair group (beach-chair, 6.1% vs lateral decubitus, 1.9%; P = .069). There was no significant difference between groups regarding RTS rates or postoperative ASES, SANE, and OSI scores at 3.3 ± 1.1 years postoperatively. Conclusion: Surgical positioning for arthroscopic anterior shoulder stabilization did not significantly affect recurrent instability, complications, and patient-reported outcomes. Both beach-chair and lateral decubitus positioning provided good outcomes for anterior shoulder stabilization, with an overall recurrent dislocation rate of 7.8% at a mean of 3.3 years after surgery.

Effect of Preoperative MRI Coracoid Dimensions on Postoperative Outcomes of Latarjet Treatment for Anterior Shoulder Instability.

Background: Preoperative coracoid dimensions may affect the size of the bone graft transferred to the glenoid rim and thus the postoperative outcomes of Latarjet coracoid transfer. Purpose: To determine the effect of coracoid length and width as measured on preoperative magnetic resonance imaging (MRI) on outcomes after Latarjet treatment of anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Included were patients who underwent primary Latarjet surgery between 2009 and 2019 and had preoperative MRI scans and minimum 2-year postoperative outcomes. Longitudinal coracoid length was measured on axial MRI sequences as the distance from the coracoclavicular ligament insertion to the distal tip. Comparisons were made between shorter and longer coracoids and between narrower and wider coracoids. The outcomes of interest were recurrent instability, reoperation, complications, return to sport (RTS), and American Shoulder and Elbow Surgeons (ASES) score. Independent-samples t test, Mann-Whitney test, chi-square test, and Fisher exact test were used to compare outcomes between groups, and univariate correlation coefficients were calculated to evaluate the relationships between demographics and coracoid dimensions. Results: Overall, 56 patients were included (mean age, 28.4 years). The mean ± SD coracoid length was 21.6 ± 2.4 mm and width 10.0 ± 1.0 mm. Relative to patients with a longer coracoid (≥22 mm; n = 26), patients with a shorter coracoid (<22 mm; n = 30) had similar rates of recurrent instability (shorter vs longer; 6.7% vs 3.8%), complications (10.0% vs 15.4%), reoperation (3.3% vs 7.7%), and RTS (76.5% vs 58.8%) and similar postoperative ASES scores (85.0 vs 81.6) (P ≥ .05 for all). Likewise, relative to patients with a wider coracoid (≥10 mm; n = 27), patients with a narrower coracoid (<10 mm; n = 29) had similar prevalences of recurrent instability (narrower vs wider; 6.9% vs 3.7%), complications (17.2% vs 7.4%), reoperation (3.5% vs 7.4%), and RTS (66.7% vs 68.4%) and similar postoperative ASES scores (87.1 vs 80.0) (P ≥ .05 for all). Conclusion: Patients undergoing Latarjet coracoid transfer had similar postoperative outcomes regardless of preoperative coracoid dimensions. These findings should be confirmed in a larger cohort before further clinical recommendations are made.

Analysis of Musculoskeletal Injuries Among Collegiate Varsity Electronic Sports Athletes.

Background Collegiate electronic sports (esports) in the United States has grown from seven varsity programs in 2016 to over 200 today. Despite its growing success, little has been studied on the injuries of these athletes. In this study, we aimed to investigate the prevalence of injuries sustained by collegiate esports players and explore the injuries' impacts on their careers. The authors hypothesized that athletes who spend more time practicing and playing competitively in esports will report an increased history of musculoskeletal injury. Methodology This was a cross-sectional study, level IV evidence. A list of collegiate esports athletes was collected from publicly available sources. Athletes with available contact information were sent a self-reporting questionnaire. The questionnaire examined variables including length of time playing esports, hours/day playing esports, esports-related injury history, surgeries needed, and missed competition time. Results Overall, 153 collegiate esports athletes (88% male, aged 18-42 years) were included, with 41 (26.8%) having experienced at least one injury from esports. Of the 41 injured athletes, three (7.3%) required surgery, 17 (41.5%) had multiple injuries, and seven (17.1%) missed competition time for an average of 3.0 ± 2.3 weeks. Athletes who have been on their respective college team longer (2.0 ± 1.0 vs. 1.7 ± 0.9 years, p = 0.03) and who spent more hours per day practicing had a higher injury incidence (p = 0.01). There was no difference in the current age, sex, age at which athletes began competing in esports, and scholarship status between groups (all p > 0.05). When analyzing the 41 athletes who experienced an injury, the most common injury was to the wrist with 25 total injuries. There were 11 neck, 10 back, nine finger, eight hand, six elbow, and four thumb injuries. Conclusions Collegiate esports players who trained for more hours per day (31.7% of injured players vs. 10.7% of uninjured players practiced more than five hours/day, p = 0.01) and played competitive collegiate esports for more years (2.0 ± 1.0 vs. 1.7 ± 0.9 years, p = 0.03) were more likely to have experienced an esports-related injury. Fortunately, only a small portion of athletes who experienced an injury was forced to miss competition time or require surgery. With this being the largest investigation into collegiate esports-related injuries, future medical research regarding the incidence, management, and prevention of its injuries can help collegiate and professional programs place a greater emphasis on the health of their athletes.
