Purpose To characterize quadriceps tendon injuries over 30 National Basketball Association (NBA) seasons and assess the effects on player performance upon return to play. Methods Partial and complete quadriceps tendon tears in NBA players between the 1990‐1991 and 2021‐2022 seasons were queried from a publicly available database. The primary outcomes were changes in player performance statistics obtained from each player’s preindex season and first 2 postindex seasons. These interseason changes were compared with the changes of a healthy control cohort. Each injured player was matched with 2 controls using position, career length and win shares by season. The secondary measure of this study was the rate of return to play. Results Nine quadriceps tendon tears (6 partial, 3 complete) were identified in NBA players. Seven (78%) of the players returned to play in NBA games, missing 50 ± 30 games and 214 ± 112 calendar days on average. Comparisons between these player’s preindex and first postindex seasons revealed significant declines in games played (73.2 ± 6.6 vs 41.8 ± 10.8, P = .009) and minutes per game (27.2 ± 2.9 vs 23.0 ± 3.7, P = .042). When compared with controls, only the decrease in games played was significant (–31.3 ± 7.6 vs 1.4 ± 8.2, P = .004). These findings were consistent when comparing preindex and second postindex seasons (games played: 79.6 ± 1.9 vs –28.4 ± 5.4, P = .006; minutes per game: 29.3 ± 2.6 vs 51.2 ± 4.6, P = .003). All other player performance metrics including player efficiency rating returned to near‐baseline levels in the first 2 seasons after injury. Conclusion NBA players with quadriceps tendon tears return to play in 78% of cases. These athletes achieved preinjury levels of performance within 1 to 2 seasons, but with reduced games played per season. Level of Evidence IV, therapeutic case series.

Background: Revision anterior cruciate ligament (ACL) reconstruction is being performed at an increasing rate. Previous literature has suggested that autograft ACL reconstruction is a better option than allograft in revision surgery, although the optimal autograft choice remains unknown. The all–soft tissue quadriceps tendon (ASTQT) autograft has been found to be an effective option for primary ACL reconstruction. However, few studies have evaluated ASTQT autograft in revision ACL reconstruction. Purpose/Hypothesis: The purpose of this study was to evaluate the ASTQT autograft in revision ACL reconstruction in athletes compared with bone–patellar tendon–bone (BTB) autograft. We hypothesized that the ASTQT autograft would lead to similar return to play, time to return to play, retear rate, and patient-reported outcomes compared with BTB autograft. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective study was performed on all athletes undergoing revision ACL reconstruction between August 2013 and December 2019 at a single institution. Patients participating in high school or college athletics undergoing first-time revision with either ASTQT or BTB autograft with ≥2 years of follow-up were included. Demographic variables, complications, return to sports, and outcome scores including the International Knee Documentation Committee (IKDC) and Lysholm were collected and compared between the 2 cohorts. Results: A total of 58 revision ACL reconstructions were included, with 32 in the ASTQT cohort and 26 in the BTB cohort. Return to sports at the same level occurred in 62.5% of the ASTQT group and 53.8% of the BTB group. The ASTQT group returned to sports significantly faster than the BTB group (8.9 vs 10.3 months; P = .020). There was no difference in retear rates (3.1%, ASTQT; 7.7%, BTB) or other complications between the 2 groups. The IKDC scores were significantly higher at the 6- and 12-month follow-up for the ASTQT autograft group compared with the BTB group (6 months: ASTQT, 71.3; BTB, 61.7, P = .001; 12 months: ASTQT, 82.7; BTB, 78.6; P = .021). Lysholm scores were also greater in the ASTQT cohort at these time points (6 months: ASTQT, 75.1; BTB, 63.6; P < .001; 12 months: ASTQT, 82.0; BTB, 74.5; P < .001). However, IKDC and Lysholm scores were similar between both groups at final follow-up (IKDC: ASTQT, 82.9; BTB, 81.7; P = .344; Lysholm: ASTQT, 83.0; BTB, 81.0; P = .104) There was no significant clinical difference in the absolute difference in scores or rate of achieving clinical thresholds between the 2 cohorts. Conclusion: ASTQT autograft for revision ACL in athletes has similar outcomes compared with BTB autograft. However, the ASTQT may possibly afford quicker return to sports and better early improvements in patient-reported outcomes that normalize by 1 year. The soft tissue quadriceps autograft should be considered a viable graft option in revision ACL reconstruction in athletes.

Background: Health and safety concerns surrounding the coronavirus 2019 (COVID-19) pandemic led the National Basketball Association (NBA) to condense and accelerate the 2020 season. Although prior literature has suggested that inadequate rest may lead to an increased injury risk, the unique circumstances surrounding this season offer a unique opportunity to evaluate player safety in the setting of reduced interval rest. Hypothesis: We hypothesized that the condensed 2020 NBA season resulted in an increased overall injury risk as compared with the 2015 to 2018 seasons. Study Design: Descriptive epidemiology study. Methods: A publicly available database, Pro Sports Transactions, was queried for injuries that forced players to miss ≥1 game between the 2015 and 2020 seasons. Data from the 2019 season were omitted given the abrupt suspension of the league year. All injury incidences were calculated per 1000 game-exposures (GEs). The primary outcome was the overall injury proportion ratio (IPR) between the 2020 season and previous seasons. Secondary measures included injury incidences stratified by type, severity, age, position, and minutes per game. Results: A total of 4346 injuries occurred over a 5-season span among 2572 unique player-seasons. The overall incidence of injury during the 2020 season was 48.20 per 1000 GEs but decreased to 39.97 per 1000 GEs when excluding COVID-19. Despite this exclusion, the overall injury rate in 2020 remained significantly greater (IPR, 1.42 [95% CI, 1.32-1.52]) than that of the 2015 to 2018 seasons (28.20 per 1000 GEs). On closer evaluation, the most notable increases seen in the 2020 season occurred within minor injuries requiring only a 1-game absence (IPR, 1.53 [95% CI, 1.37-1.70]) and in players who were aged 25 to 29 years (IPR, 1.57 [95% CI, 1.40-2.63]), averaging ≥30.0 minutes per game (IPR, 1.67 [95% CI, 1.47-1.90]), and playing the point guard position (IPR, 1.67 [95% 1.44-1.95]). Conclusion: Players in the condensed 2020 NBA season had a significantly higher incidence of injuries when compared with the prior 4 seasons, even when excluding COVID-19–related absences. This rise is consistent with the other congested NBA seasons of 1998 and 2011. These findings suggest that condensing the NBA schedule is associated with an increased risk to player health and safety.

Purpose To determine structural knee injury rates and to identify risk factors and the number of games missed associated with these injuries in National Basketball Association (NBA) players from the 2015 to 2020 seasons. Methods Publicly available player records of active NBA players between the 2015 and 2020 seasons (excluding the shortened 2019 season) were reviewed to identify players with a knee injury associated with missing one or more games. Player demographics, anthropometric measurements, statistics, injury characteristics, and history of other lower‐extremity injuries were recorded. We sought factors associated with having a structural knee injury in bivariate analysis and multivariable logistic regression. Negative binomial regression was conducted to evaluate factors associated with the total number of games missed. Results Two hundred twelve players (of 1,011, 21%) sustained a structural knee injury. Accounting for potential confounders, having a structural knee injury was associated with more minutes per game played (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0‐1.2; P = .002), a greater usage rate (OR 1.1; 95% CI 1.0‐1.2; P = .004), and a lower player efficiency rating (OR 0.94; 95% CI 0.89‐1.0; P = .041). A greater number of missed games was associated with more minutes per game (regression coefficient [RC] 0.065; 0.028‐0.10; P = .001), fewer points per game (RC –0.078; –0.14 to –0.017; P = .013), and greater usage rate (RC 0.032; 0.0040‐0.060; P = .025). Conclusions Structural knee injuries occurred in 21% of players in this study with an overall rate of 5.42 injuries per 1,000 game exposures. Significant risk factors associated with injury were minutes per game, usage rate, and true shooting percentage. Player efficiency was significantly associated with a decreased risk of injury. Increased minutes per game and usage rate were significantly associated with a longer duration of game loss. Level of Evidence Level IV, case series.

Objectives: ACL reconstruction is one of the most common knee procedures performed annually in the United States. Athletes participating in cutting and pivoting sports are at high risk for ACL injury. In the general population, most graft choices including allograft, bone-patellar tendon-bone (BTB) autograft, hamstring autograft and quadriceps autograft have all been shown to excellent results following reconstruction. However, in the high-level cutting and pivoting athlete, the optimal graft for reconstruction remains controversial. Most consider BTB autograft to be the gold standard for such athletes. However, BTB autografts have drawbacks including anterior knee pain, difficulty kneeling and possible patellar fracture and patellar tendon rupture. Quadriceps autograft has increased in popularity since it offers a thicker graft with more favorable tensile properties compared to BTB and hamstring autografts. The quadriceps autograft has nearly twice the cross sectional area, higher load to failure and greater stiffness than the BTB autograft. Studies have shown equivalent outcomes when directly comparing BTB autograft vs. soft tissue quadriceps autograft in the general population. No studies have directly compared these two grafts in athletes participating in cutting and pivoting sports. We hypothesized that the quadriceps autograft would lead to similar patient outcomes, re-tear rates, return to sport and complications as BTB autografts in the cutting and pivoting athlete. Methods: A retrospective review of cutting and pivoting athletes with ACL tears treated with BTB autograft or soft tissue quadriceps autograft with at least 2 years of follow up was performed. Only athletes participating in cutting and pivoting sports were included in the study. Four sports were considered to be cutting and pivoting including soccer, football, lacrosse and basketball. The decision on which graft to use was based on the athlete’s choice after discussing the pros and cons of each graft. Exclusion criteria included those athletes with recurrent ACL tears, multiligamentous injuries, previous meniscal surgery and those requiring osteotomies. International Knee Documentation Committee Subjective Knee Evaluation (IKDC) and Lysholm knee scoring scale were used to evaluate patient reported outcomes. Through chart review, ability to return to sport, time to return to sport and complications were identified. The postoperative rehabilitation protocol for both grafts was identical. Results: There were 32 athletes in the soft tissue quadriceps autograft group and 36 in the BTB autograft group. The average age was 18.6 years for the quad group and 19.7 years for the BTB autograft group (p=0.63). Females made up 62.5% of the quadriceps group and 44.4% of the BTB group (p=0.14). The quad group was made up of 56.3% high school and 43.7% college athletes compared to 61.1% high school and 38.9% college athletes in the BTB autograft group (p=0.53). Soccer was the most common sport with 16 in the quad group and 14 in the BTB group. The rest of the quad group included 8 football players, 4 lacrosse and 4 basketball players. The remaining BTB group consisted of 12 football players, 8 lacrosse and 2 basketball players. Meniscal surgery was performed in combination with the ACL reconstruction in 17 (53.1%) of the quad group and 22 (61.1%) of the BTB autograft group (p=0.37). Average graft size was 9.5mm for the quad autograft group and 10 for the BTB autograft group. The 2-year IKDC score was 93.6 for the quad group and 95.1 for the BTB group (p=0.45). The 2 year Lysholm scores were 95.7 and 96.1 for the quad and BTB groups respectively. Return to play at the same or higher level was 90.6% in the quad group and 86.1% in the BTB autograft group (p=0.82). Time to return was also similar between the groups with 7.1 months for the quad group and 7.6 months for the BTB autograft group. There was 1 re-tear which required revision in the BTB group and no re-tears in the quad group (p=0.34). Arthrofibrosis requiring MUA and lysis of adhesions occurred in 2 quad autografts and 4 BTB autografts (p=0.49). One contralateral ACL rupture occurred in the quad autograft group and 4 in the BTB autograft group (p=0.21). Conclusions: The optimal ACL graft in high level athletes participating in cutting and pivoting sports remains in question. In our comparison of quadriceps autograft compared to BTB autograft in this athletic population, no difference in patient reported outcomes, return to sport or re-tear rates was identified. Based on these findings, quadriceps autograft is as effective as BTB autografts in cutting and pivoting athletes and should be part of the graft choice discussion with the athlete.

Background: Bibliometric citation analyses have been widely used in medicine to help researchers gain foundational knowledge about a topic and identify subtopics of popular interest for further investigations. There is a lack of similar research in collegiate athletics. Purpose: To identify the 100 most-cited research publications related to collegiate athletics. Study Design: Cross-sectional study. Methods: The Clarivate Analytics Web of Knowledge database was used to generate a list of articles relating to collegiate athletics on January 24, 2022. Articles were filtered by the total number of citations, and the 100 most-cited articles were selected. For each article, we identified and analyzed the following: author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, sex of study population, and level of evidence. Results: Of the top 100 most-cited articles, 63 were related to medicine. In total, 96% of articles were published in the United States, and 80% were published in the year 2000 or later. Of the top 100 articles, 85 were observational; only 5 were experimental. The sport most represented was soccer, followed by football, baseball, and basketball. Of the top 100 articles, 21 were published in a single journal, the American Journal of Sports Medicine. Ten authors published ≥5 of the top 100 most-cited studies. Conclusion: The majority of top 100 articles were published in the United States after 1999 and primarily focused on medicine-related topics. Soccer was studied by more articles than football, baseball, and basketball. An author’s prestige may have influenced the likelihood of citation. The top 100 most-cited studies provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the literature on collegiate athletics.

Introduction: Away rotations have become a critical factor for a successful orthopaedic surgery residency match. Away rotations significantly improve an applicant's chance of matching into an orthopaedic residency. Away rotations were limited during the 2020 to 2021 academic year because of the COVID-19 pandemic. During the 2021 to 2022 academic year, the American Association of Medical Colleges coalition recommended students only complete 1 rotation outside their home institution, whereas the American Orthopaedic Association Council of Residency Directors argued that multiple rotations should be allowed. We sought to quantify the impact of these restrictions on orthopaedic surgery applicants during the 2020 to 2021 residency application cycle. Methods: An online survey was sent to all applicants applying to the authors' home orthopaedic surgery program. The survey asked respondents to indicate how many away rotations they completed and how many they planned to complete but were unable to complete in the 2020 to 2021 application cycle. Historical match data were obtained from the National Resident Matching Program's publicly accessible Main Residency Match Data and Reports . Results: Survey responses were collected from 650 of 812 applicants (80%) to our program. Over a third of respondents (38.1%) reported completing 3 subinternship rotations during the 2020 to 2021 application cycle. Nearly a quarter of respondents (24.0%) reported completing 4 rotations. Most applicants (50.9%) were unable to complete 5 previously planned rotations because of pandemic-related restrictions, and 25.2% reported an inability to complete 4 rotations. Fewer applicants reported canceling 3 rotations (9.2%), 2 rotations (6.8%), or 1 (7.8%) rotation. Conclusions: Away rotations have been a traditional component of the orthopaedic surgery application process. Restrictions on away rotations in the 2020 to 2021 residency application cycle had affected the number of rotations that applicants were able to complete. However, despite those restrictions, over a third of applicants were able to complete at least 3 rotations. This suggests that the away rotation experience is variable for students and may be multifactorial; however, our study did not investigate the reasons for this. Accordingly, limiting away rotations may support an inequitable environment for medical students applying to orthopaedic surgery, and creating a consensus definition among medical schools, program directors, and orthopaedic chairs of away rotations, their duration, and the maximum number allowed would enhance fairness and reduce inconsistencies.

Background: Social media and online resources have been used in graduate medical education for years. In addition to an official residency program website, many orthopaedic surgery programs have an established social media presence to interact, educate, and engage with prospective applicants. The role of social media in orthopaedic surgery has significantly expanded in recent years. Despite its increasing use, the specific impact of social media on orthopaedic surgery residency applicants remains unknown. Methods: Applicants to the home institution's orthopaedic surgery residency program were sent an optional online survey during the 2020 to 2021 application cycle. No incentive was provided in exchange for participation. Results: Of 812 orthopaedic surgery applicants, 650 (80%) completed the survey. Program-based social media is widely accessed by applicants. Instagram is used by most applicants (61.9%), and nearly a third (28.7%) rely on it as their main resource when researching prospective residency programs. The majority (66.9%) agreed that social media can be successfully used to inform and interact with applicants. Most of the applicants (60.6%) also reported that social media had a positive impact on their perception of the associated program. Only 5.7% of respondents indicated that social media had a negative influence. The most effective uses of social media seem to be in allowing a program to display its culture and transparency. Conclusion: Social media plays a substantial role in the orthopaedic surgery residency application process, and its use continues to grow. Programs can use it to effectively engage with and inform prospective applicants. The impact of social media is positive on most of the applicants. Instagram is the preferred social media platform used by applicants, and nearly one-third rely on it as their main resource when researching programs. Investing time and resources into a social media presence seems to be a worthwhile pursuit for orthopaedic surgery programs as an important piece to a well-rounded recruitment effort of modern orthopaedic surgery applicants.

Abstract Recurrent instability associated with glenoid bone loss is a commonly encountered problem after anterior shoulder dislocation. Surgical management with bony augmentation can be achieved with several allograft or autograft options. Fixation strategies also vary, including screw, suture button, or suture anchor fixation. Concerns exist regarding screw fixation because of the technical difficulty of a medial portal establishment, as well as the potential for graft osteolysis. Suture button fixation for osteochondral graft fixation has been previously described. However, no description of graft fixation using suture anchors exists. We describe an arthroscopic technique for glenoid augmentation using distal tibial allograft with suture anchor fixation. Technique Video video See video under supplementary data.

Purpose The purpose of this study is to examine the effects of scribe use on physicians, nurses, and patients in an orthopaedic sports medicine clinic. Methods Surveys containing validated outcome measures relating to physician well‐being and workplace satisfaction, among other variables, were used to assess the influence of medical scribes on clinic function. These surveys were collected for 8 months from all patients, nurses, and orthopaedic surgeons working in one orthopaedic sports medicine clinic. Time during a half‐day clinic (i.e., 20 or more patients) was documented by surgeons after the last patient was seen. Results The average time spent per half day of clinic was 104 minutes on nonscribe days and 25 minutes on scribe days. Additionally, the time spent documenting encounters per half day of clinic was 87 minutes on average without scribes and 26 minutes on average with scribes. The average surgeon single assessment numeric evaluation (SANE) score was 48.1 without scribes, and 89.3 with scribes. The overall assessment of the clinic by nurses was 73.4 out of 100 on average without scribes and 87.7 out of 100 on average with scribes. Patients did not report a significant change in rating of overall experience (4.7/5.0 with scribes and 4.8/5.0 without scribes, ( P = .27) or wait time between scheduled appointment time and surgeon arrival (15.1 minutes with scribes and 18.1 minutes without scribes; P = .12). Conclusions We found the use of scribes in a high‐volume orthopaedic sports medicine clinic to have a favorable impact on physicians, nurses, and trainees. The use of a scribe also significantly reduced the time required by surgeons for documentation during clinic and at the end of each clinic day. Patients also reported no significant difference in patient clinic experience scores. Clinical Relevance Orthopaedic surgeons spend a substantial amount of time on paperwork. The results of this study could provide information on whether the use of a scribe helps to reduce administrative burden on orthopedic surgeons.
