Retrospective Cohort Analysis of the Impact of Puberty on Plexiform Neurofibroma Growth in Patients with Neurofibromatosis Type 1.

OBJECTIVE: To assess the hypothesis that plexiform neurofibroma (PN) growth rates increase during puberty. STUDY DESIGN: PN growth rates before and during puberty were compared in a retrospective cohort of children with neurofibromatosis type 1 with puberty defined by Tanner staging. Of 33 potentially eligible patients, 25 had adequate quality magnetic resonance imaging for volumetric analysis and were included in ≥1 anchor cohort. Volumetric analysis was performed for all available imaging studies within the 4 years before and after puberty, and before and after 9- and 11-year-old anchor scans. Linear regression was performed to estimate the slope of change (PN growth rate); growth rates were compared with paired t test or Wilcoxon matched-pairs signed rank test. RESULTS: There were no significant difference in rates of PN growth in milliliters per month or milliliters per kilogram per month in the prepubertal vs pubertal periods (mean, 1.33 ± 1.67 vs 1.15 ± 1.38 [P = .139] and -0.003 ± 0.015 vs -0.002 ± 0.02 [P = .568]). Percent increases of PN volumes from baseline per month were significantly higher prepubertally (1.8% vs 0.84%; P = .041) and seemed to be related inversely to advancing age. CONCLUSIONS: Puberty and its associated hormonal changes do not seem to influence PN growth rate. These findings support those previously reported, but from a typical population of children with neurofibromatosis type 1 with puberty confirmed by Tanner staging.

Evaluating Risk Factors for Biceps Tendon Injuries in Softball Players: A Systematic Review.

OBJECTIVE: Softball players commonly suffer overuse injuries due to the demands of repetitive throwing. The biceps tendon plays an important role in stabilizing the shoulder during the windmill pitch. The purpose of this study was to evaluate the measures used to identify and study biceps tendon pathology in softball players. DESIGN: This was a systematic review. SETTING: PubMed MEDLINE, Ovid MEDLINE, and EMBASE were searched. PARTICIPANTS: Studies that investigated biceps tendon injuries in softball players. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Range of motion (ROM), strength, and visual analog scale data were collected. RESULTS: Of 152 search results, 18 were included. A total of 536 of 705 athletes (76%) were softball players (average age 14-25 years). Five of 18 articles (27.7%) studied changes in external rotation with the shoulder at 90 degrees of abduction, and 4 of 18 (22.2%) studied internal rotation. Two of 18 studies (11.1%) examined ROM or strength changes in forward flexion. CONCLUSIONS: While researchers agree that the windmill pitch places significant stress on the biceps tendon, our study finds that the metrics used to evaluate shoulder pathology in these players primarily evaluate the rotator cuff without isolating the biceps tendon. Future studies should include clinical tests and biomechanical metrics more specific to identifying biceps and labral pathology (eg, strength, fatigue, and ROM in glenohumeral forward flexion, elbow flexion, and forearm supination) and attempt to clarify differences in pathology between pitchers and position players to better characterize the frequency and severity of biceps tendon pathology in softball players.

Program Directors' Perception of the Role of Personal Statements in the Orthopaedic Surgery Residency Selection Process.

The purpose of this study was (1) to determine how much emphasis is placed on the Personal Statement (PS) by program directors (PDs) and (2) to gain a better understanding of what factors within the PS are considered most important to PDs. An anonymous survey was distributed to PDs at allopathic orthopaedic residency programs in the United States using Survey Monkey (San Mateo, CA). Survey responses were received from 51 of 152 (34%) PDs. Forty-five (88.2%) identified as male, five (9.8%) identified as female, and one (1.9%) chose not to disclose. PDs reported the PS was of average importance, with an average score of 2.82 (range,1-4). Although the PS is still given consideration as part of the overall orthopaedic surgery residency application process, it does not play a major role in determining which applicants will be invited for an interview or how they will be ranked.

Factors Contributing to Diurnal Variation in Athletic Performance and Methods to Reduce Within-Day Performance Variation: A Systematic Review.

ABSTRACT: Kusumoto, H, Ta, C, Brown, SM, and Mulcahey, MK. Factors contributing to diurnal variation in athletic performance and methods to reduce within-day performance variation: A systematic review. J Strength Cond Res 35(12S): S119-S135, 2021-For many individuals, athletic performance (e.g., cycle ergometer output) differs based on the time of day (TOD). This study identified factors contributing to diurnal variation in athletic performance and methods to reduce TOD performance variation. Comprehensive searches of PubMed, Ovid, EMBASE, Web of Science, and Cochrane Libraries were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Peer-reviewed publications reporting quantitative, significant diurnal variation (p ≤ 0.05) of athletic performance with explanations for the differences were included. Studies providing effective methods to reduce diurnal variation were also included. Literature reviews, studies involving nonhuman or nonadult subjects, studies that intentionally manipulated sleep duration or quality, and studies deemed to be of poor methodological quality using NIH Quality Assessment Tools were excluded. Forty-nine studies met the inclusion criteria. Body temperature differences (n = 13), electromyographic parameters (n = 10), serum biomarker fluctuations (n = 5), athlete chronotypes (n = 4), and differential oxygen kinetics (n = 3) were investigated as significant determinants of diurnal variation in sports performance. Successful techniques for reducing diurnal athletic performance variability included active or passive warm-up (n = 9), caffeine ingestion (n = 2), and training-testing TOD synchrony (n = 3). Body temperature was the most important contributor to diurnal variation in athletic performance. In addition, extended morning warm-up was the most effective way to reduce performance variation. Recognizing contributors to diurnal variation in athletic performance may facilitate the development of more effective training regimens that allow athletes to achieve consistent performances regardless of TOD.

Examining Techniques for Treatment of Medial Meniscal Ramp Lesions During Anterior Cruciate Ligament Reconstruction: A Systematic Review.

PURPOSE: The purpose of this study was to systematically review the clinical outcomes and adverse events among different techniques for treatment of medial meniscal ramp lesions performed in conjunction with anterior cruciate ligament (ACL) reconstruction. METHODS: A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Cochrane Reviews, Web of Science, and Medline databases were searched for studies examining clinical outcomes after surgical treatment of ramp lesions. Studies were selected if they met the following criteria: (1) evaluation of the outcome of surgical repair of meniscal ramp lesions, (2) injuries associated with ACL tears, (3) minimum 6-month follow up, (4) publication in a peer-reviewed journal, and (5) English language or translation readily available. RESULTS: Seven studies met inclusion criteria (485 patients; mean age 27.1 years [range 12 to 59]; mean follow-up 26.9 months [range 8 to 40]). Two all-inside techniques (suture-hook and an all-inside meniscus repair device) in addition to abrasion and trephination alone were analyzed. Each technique demonstrated significant increases in postoperative Lysholm and International Knee Documentation Committee (IKDC) scores, reaching the established minimal clinically important difference (MCID) for each patient reported outcome. Incomplete healing was documented in 12.1% to 12.9% of cases in which the tear was not repaired at the time of ACL reconstruction, 2.3% to 11.7% in cases using the suture-hook for repair, and 10.8% to 15% in the all-inside meniscus repair device group. CONCLUSION: This systematic review demonstrated that several approaches used to treat medial meniscal ramp lesions associated with ACL tears lead to positive clinical outcomes. Small, stable tears <2 cm in size may be managed with debridement alone. For larger, more unstable lesions, an all-inside approach has demonstrated positive clinical outcomes. Prospective trials are needed to determine the best management for meniscal ramp lesions. Additionally, further research is needed to better understand how to minimize the risk of technique-related complications (e.g., improper implant deployment). LEVEL OF EVIDENCE: Level IV, systematic review of level II, III, and IV studies.

Epidemiology of Shoulder Instability Injuries in Collision Collegiate Sports From 2009 to 2014.

PURPOSE: To describe the types, mechanisms, and severity of shoulder instability injuries in collegiate collision athletes during the 2009-2010 through 2013-2014 academic years using the National Collegiate Athletic Association Injury Surveillance Program; to compare the injury incidence between men's collision sports and their women's non-collision counterparts, when possible; and to compare injury outcomes between Divisions I, II, and III. METHODS: Data regarding men's football, wrestling, ice hockey, and lacrosse, as well as women's ice hockey and lacrosse, were obtained. Injuries requiring attention from a health care provider were reported. Incidence rates per 100,000 athlete-exposures (AEs) were calculated with 95% confidence intervals (CIs). Analysis of variance was used to compare time loss (TL), and χ2 analysis was used to compare surgery rates between divisions. RESULTS: A total of 445 shoulder instability injuries occurred in 1,421,561 AEs from 2009-2010 to 2013-2014 (incidence rate, 31.30 injuries/100,000 AEs; 95% CI, 28.4-34.21 injuries/100,000 AEs). Subluxation accounted for 59.1% of injuries, with anterior subluxation (35.3%) being the most common injury. Dislocation resulted in the most TL per injury (17.58 days). Mean TL for all injuries was 8.17 days (standard deviation, 7.21 days). When non-time-loss injuries were excluded from analysis, players experienced a mean TL of 18.34 days (standard deviation, 8.44 days). Divisions I (4.77 days), II (20.52 days), and III (11.23 days) differed significantly in mean TL (P = .01). Of the injuries, 29.3% required surgery. The surgery rates for Divisions I (32.9%), II (38.1%), and III (19.4%) also differed significantly (P = .04). Men's ice hockey and lacrosse players sustained a 2.17-fold (95% CI, 1.04-4.50) higher incidence of shoulder instability than their female counterparts. CONCLUSIONS: Anterior subluxation and dislocation accounted for 52.1% of all shoulder instability injuries. Injured athletes missed 8 days on average, and nearly 30% of injuries required surgery. Surgery rates and TL were significantly different between Divisions I, II, and III. Female athletes playing non-collision ice hockey and lacrosse experienced significantly lower shoulder instability rates than their male counterparts. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Softball pitching mechanics and shoulder injuries: a narrative review.

Softball is the third most popular women's collegiate sport in the United States, with 19,680 total athletes as of the 2015-2016 season. Despite its popularity and growth in recent years, research focusing on the biomechanics of the windmill pitch and its associated shoulder injuries is relatively scarce. The incidence of shoulder injury is highest during the preseason and the beginning of the regular season. The windmill pitch can be divided into distinct phases, with the shoulder experiencing the greatest force during the delivery phase. Significant demands placed on the shoulder during the windmill pitch put pitchers at a higher risk of developing shoulder injuries than position players. Maximum shoulder compression/distraction forces during the windmill pitch have been shown to be comparable to those experienced during the baseball overhand throw, dispelling the myth that the windmill pitch is not taxing on the shoulder. Injuries associated with the high compression/distraction forces include lesions to the rotator cuff, glenoid labrum, and biceps brachii. Pitcher-specific training, cross-training, and whole-body conditioning should be incorporated into current training regimens to decrease the risk of shoulder injuries.

Readability and Variability Among Online Resources for Patella Dislocation: What Patients Are Reading.

The purpose of this study was to evaluate the readability, content, and authorship of websites related to patella instability. A search was performed using three search engines and four terms related to patella dislocation. Thirty-seven unique websites were identified. Seventeen of 37 (46%) websites disclosed the authorship credentials. The mean Flesch-Kincaid grade was 10.8±3.5, and the mean Flesch reading ease score was 47.6±18. Only 8 of 37 (22%) websites had a third-party Health On the Net seal. The information presented online about patella dislocation can be unreliable and misleading for patients.

Effective Interventions for Improving Functional Movement Screen Scores Among "High-Risk" Athletes: A Systematic Review.

BACKGROUND: The Functional Movement ScreenTM (FMSTM) is a tool designed to screen a series of movements that aids in the identification of compensatory fundamental movement patterns, functional limitations, and asymmetrical movement patterns. A previous systematic review and meta-analysis has shown that athletes with an FMSTM score <13-14 are considered "high-risk" and are more likely to be injured. There are discrepancies regarding the efficacy of physical intervention programs in improving FMSTM scores. PURPOSE: The aim of this systematic review was to assess the role of physical intervention programs in increasing functional movement in "high-risk" athletes as measured by the FMSTM. STUDY DESIGN: Systematic Review. METHODS: A computerized search was performed in 2019 according to PRISMA guidelines searching Embase, Science Direct, Ovid, and PubMed. The studies were assessed for quality and risk of bias using the Modified Downs and Black checklist. Participant demographics, intervention routines, and FMSTM scores were extracted from the included studies. RESULTS: Six studies met the inclusion criteria and demonstrated a fair methodological quality. Comparisons across all studies revealed significant improvement in FMSTM scores following implementation of a variety of physical intervention programs. These programs included those that utilized functional training, foot muscle strengthening, Pilates, core stability training, and resistance movements. Despite variations in the corrective exercises performed, the number of training sessions, and the length of the intervention program, all studies demonstrated an increase in the total FMSTM score following program implementation. CONCLUSION: The included intervention programs significantly improved total FMSTM scores in "high-risk" athletes. Despite variations in the corrective exercises (interventions) performed, the number of training sessions, and the length of the program, all studies demonstrated a significant increase in the total FMSTM score following program implementation.

Women in Leadership in State and Regional Orthopaedic Societies.

INTRODUCTION: Female representation in orthopaedics remains low compared with other specialties. Recently, several studies have examined the membership composition and leadership roles of women in orthopaedic societies. However, there is a paucity of information on the possible connection between the number of women within state and regional orthopaedic societies and women who serve in leadership roles within these societies. METHODS: Authors invited executive directors of 51 state and four regional orthopaedic societies to participate in an anonymous 14-question web-based survey about female members and women in leadership positions within these societies. The survey asked about female membership composition, the percentage of male and female practicing orthopaedic surgeons in the state/region (if available), and female representation on the Board of Directors of these societies. Data were analyzed for relationships between ordinal variables. RESULTS: Forty-nine executive directors (89.1%) responded to the survey. Among respondents, there was a statistically significant positive correlation between the percentage of female members and women leaders (P = 0.015). Thirty-two executive directors (68.1%) reported between 1% and 10% female members, 7 (14.9%) had between 11% and 20% female members, and 2 (4.3%) had no female members. Twenty-five societies (52.1%) have never had a female president. Of 17 societies (32.7%) that had female presidents, 15 (75.0%) reported having just one female president. In addition, of these 17 societies, 12 (70.6%) reported having at least one acting female president within the past 10 years. DISCUSSION: Our study demonstrates a positive correlation between female members and women on the Board of Directors in regional and state orthopaedic societies. Twelve societies had female presidents within the past 10 years. Female representation in leadership positions may help with the recruitment of female orthopaedic surgeons and improve diversity in orthopaedics. Future studies should evaluate different methods of increasing female membership and leadership positions in state and regional orthopaedic societies.

The relationship between the orthopedic job market and sports medicine fellowship applications between 2010 and 2017.

Objectives: More than 90% of graduating orthopedic residents pursue at least one year of fellowship training. There are no studies to date that examine the trends for sports medicine positions in the orthopedic job market. The purpose of this study was to evaluate trends in orthopedic sports medicine positions using postings from four orthopedic journals. Methods: Print advertisements for job positions in three American orthopedic journals (Journal of Bone and Joint Surgery, Journal of the American Academy of Orthopaedic Surgeons, and American Journal of Sports Medicine) between 2010 and 2017 were reviewed. The results were compared to sports medicine fellowship match trends. Results: Between 2010 and 2017, there were a total of 403 postings for orthopedic sports medicine positions, 186 in Journal of Bone and Joint Surgery, 113 in Journal of the American Academy of Orthopaedic Surgeons, and 52 in American Journal of Sports Medicine. There was a 43% decline in print sports medicine advertisements from 2010 to 2015. The number of job advertisements for sports medicine positions remained consistent (approximately 10%) from 2010 to 2015, then dropped to 2.1% (57/2698) and 1.4% (66/4735) in 2016 and 2017, respectively. Conclusion: There is no direct correlation between job positions advertised in orthopedic journals and sports medicine fellowship positions offered. Additionally, there has been an increase in job advertisements requiring fellowship training, indicating an increased demand for sub-specialty trained orthopedic surgeons. Lastly, the drop in total orthopedic advertisements in the years proceedi ng 2015 may serve as a harbinger for the transition to largely online content, and job postings in journals may not be the most reliable source of job opportunities, but further investigation should be done in relation to this topic.

Injury Prevention Programs for Throwing Injuries in Softball Players: A Systematic Review.

CONTEXT: Throwing-related injuries occur commonly in softball players. Preventative programs can be implemented to assist in identifying and correcting risk factors that could potentially lead to injury and therefore time missed from both practice and games. OBJECTIVE: The purpose of this study was to determine if position-specific injury prevention programs have been developed to decrease the risk of throwing-related injuries in softball players. DATA SOURCES: A systematic review was performed using the PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-Analyses) guidelines. PubMed, PMC, and EBSCO were searched for articles on injury prevention programs using the following key terms: softball, injury prevention, throwing injuries, pitcher, and shoulder. STUDY SELECTION: Studies that involved fast-pitch softball and included female participants as well as rehabilitation programs were included. Articles that highlighted slow-pitch softball or did not include female participants were excluded. LEVEL OF EVIDENCE: Level 1. DATA EXTRACTION: The initial search identified 1605 articles. After implementing a filter, 131 articles remained. Thirteen articles were screened out as duplicates. After screening for inclusion criteria, 7 articles remained and were included in the systematic review. RESULTS: Decreased range of motion (ROM) in both the upper and the lower extremities, unbalanced muscular strength, and fatigue were identified as risk factors for throwing injuries in softball players. Within the upper extremity, strength and ROM of the rotator cuff muscles, biceps, and extensors of the forearm were emphasized. The main focus of the lower extremity was the strength of the gluteal muscles and ROM of the lumbopelvic-hip complex. Only 1 study detailed an injury prevention program for softball players. The prevention program outlined was generalized for all softball players and was not position specific. CONCLUSION: There is a paucity of information about injury prevention programs for softball players. Of the evidence analyzed, balanced strengthening of the upper and lower extremities while maintaining dynamic range of motion was frequently utilized in developing an injury prevention program.

Orthopaedic In-training Exam Preparation among Orthopaedic Surgery Residency Programs.

OBJECTIVE: The Orthopaedic In-Training Examination (OITE) is given annually to residents to assess their knowledge of clinical orthopaedics and orthopaedic basic science. This study sought to determine what resources orthopaedic residency programs recommend and/or require for residents as preparative tools for the OITE and to understand which resources are most beneficial. DESIGN: An anonymous electronic survey was distributed to program directors of orthopaedic surgery residency programs. It included questions about resources that program directors recommended or required residents to use when preparing for the OITE. SETTING: The survey was prepared and the results analyzed at two academic medical institutions in Louisiana. The survey was available to respondents in December 2019 and January 2020. PARTICIPANTS: The survey was delivered to program directors of 148 ACGME accredited orthopaedic surgery residency programs in the United States. RESULTS: 148 orthopaedic surgery residency program directors received the survey and 44 responded (response rate: 29.7%). Twenty-nine programs (73.2%) reported that practice tests/review of old OITE exams positively correlated with better scores. The most recommended resources for OITE preparation were Orthobullets (35 programs; 85%) and Res Study (AAOS) (27 programs; 67.5%). Programs having formal/required preparation programs had lower mean overall scores on the OITE than programs that did not. Those without a formal/required program scored in the 60th percentile, while those with a formal/required program scored in the 53.3rd percentile, a difference of 6.7 percentile points (p = 0.049). The mean overall percentiles were significantly higher for programs that reported having a threshold/goal OITE score for residents compared to those that didn't. Programs with a threshold/goal score scored in the 60.6th percentile on average, while those without a threshold/goal score scored in the 51.7th percentile on average, a difference of 8.9 percentile points (p = 0.0095). CONCLUSIONS: There is substantial variability in the resources that are utilized in preparation for the OITE, with the most commonly recommended resource being Orthobullets. The study method most cited as having a positive impact on scores was practice tests/review of old OITE exams. Having a formal/required program resulted in programs having lower OITE scores. Setting a goal/threshold score correlates positively with an increase in OITE score. Encouraging residents to use practice questions/old OITE tests, setting a goal/threshold score and avoiding formal/required preparation programs may improve resident performance on the OITE.

Orthopaedic Sports Medicine Fellowship Websites: Information Considered Most Important to Fellowship Applicants.

INTRODUCTION: The purpose of this study was to determine which components of sports medicine fellowships are most important to applicants when reviewing fellowship websites during the application process. METHODS: An anonymous survey was distributed to 492 fellowship applicants from the 2017-2018 and 2018-2019 cycles. The survey included questions about the importance of including components of fellow education, recruitment, and experience on program websites. The weighted average of responses determined each component's rank, with 5 being "very important" and 1 being "not at all important." Responses were analyzed by application cycle, current position, and sex using the Wilcoxon rank-sum test. RESULTS: Sixty-five applicants participated in the survey and completed the demographics section, resulting in a 13.2% response rate. According to participants, the most important components to include on fellowship websites were exposure to advanced operative sports medicine techniques (weighted average, 4.62), complexity of cases performed (4.52), and number of cases performed (4.50). Analysis demonstrated statistically significant differences in opinion between application cycles for flexibility for conducting a remote interview (P = .0074), jobs obtained by previous fellows (P = .019), national rank of department (P = .021), program's geographic location (P = .026), protected academic time (P = .038), current positions for criteria for fellows' performance evaluations (P = .028), program's geographic location (P = .0097), and protected academic time (P = .0079). There were statistically significant differences in opinion between current positions regarding flexibility for conducting a remote interview (P = .0026), jobs obtained by previous fellows (P = .012), and national rank of department (P = .0013). CONCLUSIONS: Orthopaedic sports medicine fellowship applicants believe that it is most important to include information about the volume and complexity of fellows' cases and their day-to-day commitments on program websites. CLINICAL RELEVANCE: This information would enable applicants to identify programs that will support professional development and allow program directors to communicate expectations.

Gap Year Research Fellowship Opportunities for Medical Students Interested in Orthopaedic Surgery.

INTRODUCTION: Orthopaedic surgery is becoming an increasingly competitive specialty. The purpose of this study was to identify existing orthopaedic research fellowships in the United States and to determine important characteristics including the number of positions offered by each program and the average number of publications from completing the program. METHODS: An online search was performed to identify year-long orthopaedic research fellowship programs available for medical students and recent medical school graduates. The number of positions per program and average number of publications of recent program graduates were also obtained. RESULTS: A total of 30 research fellowship programs were identified throughout the United States (13 in the northeast; six in the south; nine in the midwest; and two in the west) that are offered consistently each year. The average number of fellows per program was 3.1 (range 1 to 10) and the average number of publications was 10.8 (range 2 to 20). CONCLUSION: At least 30 orthopaedic research fellowships in the United States are available to students who are looking to acquire more research experience and strengthen their application for orthopaedic residency. These fellowships can help medical students increase their probability of matching into orthopaedics through publications, networking, and clinical exposure.

Topical nonsteroidal anti-inflammatory drugs in the treatment of knee osteoarthritis: a systematic review and meta-analysis.

OBJECTIVE: To compare the efficacy and safety of topical nonsteroidal anti-inflammatory drugs (NSAIDs) against placebo and active controls for improving pain and physical function of patients with knee osteoarthritis (OA). We hypothesize that topical NSAIDs will be safe and effective for relieving symptoms in patients with knee OA. METHODS: The authors performed a systematic review according to the PRISMA guidelines, searching PubMed, EMBASE, and Cochrane databases. Randomized control trials that investigated topical NSAIDs that are widely available in many countries against both placebo and active controls in primary knee osteoarthritis were included. Studies that investigated other treatment modalities or treated nonspecific OA were excluded. A meta-analysis was performed to quantify the effect sizes and heterogeneity of the NSAIDs used. RESULTS: Upon initial search, 259 records were identified with 18 studies remaining after duplicate removal, abstract, and full-text screening. All NSAIDs demonstrated statistically significant reduction in at least one parameter of OA symptoms. The majority of included studies (66.7%) evaluated diclofenac. In the meta-analysis, standardized mean differences (SMD) of topical NSAIDs versus placebo were calculated and interpreted as having moderate effect size for improvement in pain (0.365, 95% confidence interval (CI) 0.240, 0.490) and physical function (0.354, 95% CI 0.268, 0.493). With regard to safety, studies that used patches or dimethyl sulfoxide (DMSO) in the carrier reported a higher incidence of adverse events (AEs) than other carriers. Skin AEs were higher in the treatment group than the placebo group and gastrointestinal AEs were lower in the treatment group than placebo. CONCLUSION: Topical diclofenac and ketoprofen are the most rigorously studied topical NSAIDs in the treatment of knee OA and have demonstrated the most significant reduction in pain and improvement of function. Ibuprofen was effective for pain relief and physical function improvement, but more high-powered studies are needed to make a confident comparison of efficacy. Additionally, the 'carrier' used to deliver the topical NSAID has an impact on the adverse event profile. This has safety implications for prescribers and pharmaceutical development. Topical diclofenac is widely available internationally and is the only topical NSAID approved for over-the-counter use in the US. It should be recommended to patients as a first-line conservative management for OA of the knee.

Gender disparity among NBA and WNBA team physicians.

BACKGROUND: Female physicians are underrepresented across a broad range of medical specialties, especially at senior levels. Previous research demonstrated poor representation of women in sports medicine leadership roles in the National Collegiate Athletic Association (NCAA) compared to their male colleagues. PURPOSE: The purpose of this study was to evaluate the distribution of men and women among team physicians on the medical staffs of National Basketball Association (NBA) and Women's National Basketball Association (WNBA) teams in the last 10 years and assess regional differences in representation of female physicians. METHODS: A Google search of publicly available data regarding team physician gender, medical specialty, and medical degree was conducted in October 2019 for team physicians in the NBA and WNBA over the last 10 years. Descriptive statistics were used to analyze the data. This data was then stratified by physician specialty and region of country in which NBA/WNBA franchises are located to provide regional comparison of team physician characteristics. RESULTS: We identified 125 team physicians for NBA franchises. Of these, 122 (97.6%) were male and 3 (2.4%) were female. In the WNBA, a total of 28 physicians were identified. 20 (71.4%) were male and 8 (28.6%) were female. The Northeast had the highest proportion of female team physicians, with 5 of 18 (27.8%). Female physicians were represented in the remaining geographic regions as follows: 3 of 41 (7.3%) in the Midwest, 2 of 45 (4.4%) in the South, and 1 of 48 (2.1%) in the West. CONCLUSION: This study demonstrates a substantial difference in the number of female physicians with leadership roles in both the NBA and WNBA compared to male physicians. It is important to try to understand what barriers female physicians face in their pursuit of upper level positions in sports medicine and to implement strategies to provide equal opportunities to both male and female physicians.

Research Productivity of Orthopaedic Sports Medicine Fellowship Programs in the United States.

PURPOSE: To survey orthopaedic sports medicine fellowship program directors to determine the current research productivity of both fellows and faculty in Accreditation Council for Graduate Medical Education-accredited orthopaedic sports medicine fellowship programs in the United States. METHODS: An anonymous 18-question survey was distributed via e-mail to all 95 Accreditation Council for Graduate Medical Education-accredited orthopaedic sports medicine fellowship program directors in the United States. Descriptive statistics were used for data analysis. Questions included whether fellows are required to complete a certain number of projects during their fellowship year and whether fellows have protected research time. RESULTS: Of the programs, 31 (33%) responded to the survey. Twenty-four programs (80%) require fellows to complete 1 to 4 projects. Twenty-one programs (71%) provide 4 to 8 hours of weekly protected research time. Twenty-four programs (77%) publish 1 to 2 manuscripts per fellow during the fellowship. Twenty-two programs (71%) have fellows work on 1 to 2 projects at a time. Annually, 26 programs (84%) give 0 to 5 podium presentations, 24 (80%) present 0 to 5 posters, and 15 (48%) report 0 to 5 publications. Twenty-four programs (77%) have research fellows and/or assistants to help with research. The presence of dedicated research assistants and more than 25 annual fellowship program publications were found to be useful screening data for more than 2 and more than 4 average publications per fellow, respectively. CONCLUSIONS: The research productivity of orthopaedic sports medicine fellowship programs may be an important consideration for applicants. Applicants who desire to be productive in research during their fellowship year should consider programs with dedicated research assistants and/or programs that publish more than 25 times annually. CLINICAL RELEVANCE: This is a descriptive epidemiologic study that helps define the research productivity landscape in orthopaedic sports medicine fellowships. A more accurate understanding of sports medicine fellowship research experience may facilitate a better match between a program's research expectations and an applicant's research interests.

Injury Profile of Mixed Martial Arts Competitions in the United States.

BACKGROUND: The popularity of mixed martial arts (MMA) continues to grow in the United States. Although prior work has provided valuable insight concerning injuries in the sport, much of the available literature is limited by factors such as small sample sizes, varying athlete demographics, and inconsistent data collection methods. PURPOSE: To report injury rates and types in MMA and analyze potential variance between competition and match variables. STUDY DESIGN: Descriptive epidemiology study. METHODS: We performed a retrospective review of injuries sustained by fighters during MMA contests between 2018 and 2019 using ringside physician postmatch injury reports from Wisconsin and Arizona. The prevalence of overall injuries and specific injury types was compared by location (Arizona vs Wisconsin), competition level (amateur vs professional), match result (decisions vs any other result), and match winners versus losers. RESULTS: In 503 contests, 285 (57%) had at least 1 injury. In these 285 matches, participants experienced 401 injuries: 197 (49%) in professional bouts and 204 (51%) in amateur bouts. The match injury rate was higher in professional bouts than in amateur contests (68% vs 51%; P < .001). Amateur fighters had more contusions and hematomas (31% vs 22%; P < .001), while professional fighters had more lacerations (39% vs 23%; P < .001). Losers exhibited a higher match injury rate than winners (48% vs 24%; P < .001). Winners experienced a higher proportion of fractures (19% vs 9%; P = .005), and losers experienced more concussions (17% vs 2%; P < .001). CONCLUSION: Professional fighters and losers of MMA bouts exhibited higher injury rates relative to amateurs and winners. The prevalence of specific injury types varied by competition level, match result, and match winners versus losers. The results of this study may be used to better understand the current injury profile in MMA and to develop targeted strategies for injury prevention.

Prophylaxis for Heterotopic Ossification Following Distal Biceps Tendon Repair.

Heterotopic ossification (HO) is a possible complication of distal biceps tendon repair (DBTR). Several agents can prevent HO formation, although relatively few studies have investigated prophylaxis specifically after DBTR. The purposes of this study were to survey members of the American Shoulder and Elbow Surgeons (ASES) to determine (1) what percentage use HO prophylaxis after DBTR; (2) type, dosage, and duration of prophylaxis used; and (3) use of single-incision or double-incision surgical technique. An anonymous electronic survey was distributed to ASES members to determine the use of HO prophylaxis and DBTR technique. The survey included questions regarding the number of DBTRs performed annually; preferred surgical technique and implants; and type, dosage, and duration of HO prophylaxis used before, during, and after surgery. Descriptive statistics were used to analyze the results. Of 173 respondents, 98 (56.6%) performed 1 to 10 DBTRs per year, 65 (37.6%) performed 11 to 25 DBTRs per year, and 10 (5.8%) performed 26 to 50 DBTRs per year. A total of 131 (75.7%) preferred the single-incision technique, whereas 42 (24.3%) preferred the double-incision technique. A total of 94 (54.3%) performed DBTR using a metal button and interference screw, 35 (20.2%) through drill holes, 25 (14.5%) with suture anchors, and 19 (11.0%) with a metal button alone. A total of 132 (76.3%) respondents did not use HO prophylaxis, and 41 (23.7%) used nonsteroidal anti-inflammatory drugs following surgery. A total of 35 (85.4%) used indomethacin, 18 (51.4%) of whom preferred 75 mg/d for 3 to 4 weeks. Heterotopic ossification is a commonly reported complication following DBTR, especially with the double-incision technique. Prophylaxis with anti-inflammatory medications and suppressive modalities (radiation therapy) appear to reduce the incidence of HO. Despite these data, most surgeons (76.3%) do not use HO prophylaxis. Low annual volume of cases, lack of large-volume studies with outcome data, and the dominant use of the single-incision repair technique may explain this. [Orthopedics. 2021;44(4):e588-e592.].
