Abstract
INTRODUCTION Chondral and osteochondral defects of the knee are common injuries in the military population that have a significant impact on readiness. Definitive treatment of these injuries is challenging since cartilage has a limited capacity for self-repair and regeneration. Management is particularly challenging in military patients who maintain a higher level of activity similar to athletes. Existing surgical techniques have variable results and often long recovery times, sparking the development of several new innovative technologies to return service members back to duty more quickly and effectively after cartilage injury. The purpose of this article is to review the current and future surgical treatments for chondral and osteochondral knee lesions and their relevance in managing these injuries in the military. METHODS In this review article, we describe the current treatments for chondral and osteochondral defects of the knee, reporting on outcomes in military populations. We explore emerging treatment modalities for cartilage defects, reporting innovations, stage of research, and current data. Published results of each treatment option in military populations are reviewed throughout the article. RESULTS This review includes 12 treatments for chondral lesions. Of these therapies, four are considered synthetic and the remaining are considered regenerative solutions. Regenerative therapies tend to perform better in younger, healthier populations with robust healing capacity. Success of treatment depends on lesions and patient characteristics. Nearly all modalities currently available in the USA were successful in improving patients from presurgical function in the short (<6 months) term, but the long-term efficacy is still challenged. Upcoming technologies show promising results in clinical and animal studies that may provide alternative options desirable for the military population. CONCLUSIONS The current treatment options for cartilage lesions are not entirely satisfactory, usually with long recovery times and mixed results. An ideal therapy would be a single procedure that possesses the ability to enable a quick return to activity and duty, alleviate pain, provide long-term durability, and disrupt the progression of osteoarthritis. Evolving technologies for cartilage lesions are expanding beyond currently available techniques that may revolutionize the future of cartilage repair.

Abstract
Objective Lower extremity ankle and knee injuries occur at a high rate in the National Basketball Association (NBA) often requiring surgical intervention. This study aimed to identify surgical rates and risk factors for surgical intervention using multivariate analysis in ankle and knee injuries in NBA player. Methods Player demographics, performance metrics, advanced statistics, and injury characteristics were recorded using publicly available data. To standardize injury events over multiple years, injury events per 1000 athlete exposure events (AE, one player participating in one game) were calculated. Descriptive analysis and multivariate logistic regression were completed to find associations with surgical intervention in ankle and knee injuries. Results A total of 1153 ankle and knee injuries were included in the analysis with 73 (6.33%) lower extremity injuries treated with surgery. Knee injuries had a higher incidence of surgical intervention (0.23 AE) than ankle injuries (0.04 AE). The most frequent surgical knee injury was meniscus tear treated with meniscus repair (0.05 AE) and the most frequent ankle surgery was surgical debridement (0.01 AE) Multivariate logistic regression indicated lower extremity injuries that required surgery were associated with more minutes per game played (odds ratio [OR] 1.13; p = 0.02), a greater usage rate (OR 1.02 p < 0.001), the center position (OR 1.64; 95% [CI] 1.2-2.24; p = 0.002) and lower player efficiency rating (OR 0.96; 95% p < 0.001). Conclusion Knee surgery was significantly more frequent than ankle surgery despite similar injury rates per 1000 exposures. The center position had the greatest risk for lower extremity injury followed by minutes played while a higher player efficiency rating was protective against surgical intervention. Developing strategies to address these factors will help in the management and prevention of lower extremity injuries requiring surgical intervention.

Abstract
Purpose To determine clinical outcomes associated with micronized allogenic cartilage scaffold use for treatment of posterior glenoid cartilage defects at 2 years. Study Design Case series. Methods A retrospective analysis of prospectively collected data was performed on a consecutive series of patients who underwent arthroscopic treatment of a symptomatic posterior glenoid cartilage defect with micronized allogenic cartilage scaffold between January 2019 and December 2020. The primary outcome was subjective shoulder value (SSV) at latest follow-up. Secondary outcomes included visual analog scale (VAS), recurrence of instability, and range of motion (ROM). Results Seven patients, including 4 in the setting of primary posterior instability and 3 in the setting of recurrent symptoms after arthroscopic posterior glenohumeral stabilization, were included in the analysis with a mean follow up of 2.6 years (range, 2-3.7 years). Statistically significant improvements were seen in SSV (median = 40, interquartile range [IQR] = 40-50 before surgery; vs median = 85, IQR = 67.5-87.5 after surgery; P = .018) and VAS (median = 4, IQR = 4-6.3 before surgery; vs median = 1, IQR = 0-1.5 after surgery; P = .010). No significant differences were seen in ROM. There were no cases of recurrent instability or reoperation. Conclusions The use of micronized allogenic cartilage scaffold for glenoid cartilage defects is associated with clinical improvement at 2-year follow-up. This is the case when performed in conjunction with index posterior labral repair when there is a concomitant glenoid cartilage defect or when performed in the setting of persistent pain and mechanical symptoms after prior posterior labral repair. Level of Evidence Level IV, therapeutic case series.

Abstract
Knee injuries, particularly anterior cruciate ligament (ACL) damage and cartilage defects, are highly prevalent among athletes and affect their sports performance and long-term joint function. The purpose of this research was to evaluate the effectiveness of a comprehensive combination therapy approach for individuals with ACL and cartilage injuries. Twelve professional soccer players aged 18 to 30 years underwent bone-tendon-bone ACL reconstruction, microfracture cartilage repair surgery, and hyaluronic acid scaffold treatment. Early postoperative rehabilitation included immediate supervised physiotherapy and complete weight bearing. Follow-up assessments involved clinical evaluations, functional joint assessments, and magnetic resonance imaging (MRI) scans to measure cartilage defect repair and symptom alleviation. The results showed that patients resumed pain-free activities within 3-4 weeks and returned to their pre-injury level within 4.5 months. MRI demonstrated the absence of inflammatory reactions, repair of marrow edema, and the emergence of new cartilage. Six months and one year after surgery, the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Short Form (36) Health Survey (SF-36) questionnaire results demonstrated considerable improvement in patients' health condition and quality of life. Overall, the study suggests that the combination of Hyalofast membranes, microfracture surgery, tissue adhesive, and intensive postoperative physical therapy may be a potential alternative to commonly used treatments for patients with ACL rupture, allowing them to recover efficiently and return to sports activities.

Abstract
Background and Objectives: This study evaluated the effectiveness of Hyalofast cartilage repair surgery with an early, full load-bearing rehabilitation program one day after the operation for reducing the time needed for professional athletes to return to play. Materials and Methods: This prospective study included 49 patients aged between 19 and 38 years who had undergone surgical reconstruction of cartilage using the microfracture technique combined with a Hyalofast scaffold. All patients were active professional athletes. Early rehabilitation was implemented from the first postoperative day, fully loading the operated limb. A clinical evaluation was based on the KOOS and SF-36 questionnaires used during subsequent follow-up visits. All patients underwent magnetic resonance imaging (MRI) to evaluate the effect of the surgery after one year. Results: The clinical results demonstrated a statistically significant improvement in the number of complaints about pain and in the quality of life of the patients, measured in all of the applied scales, with comparisons made between six months or one year post-surgery and pre-surgery. Importantly for athletes, the parameter related to sports and recreation improved from 14 ± 11.1 to 95 ± 7.7 6 months after surgery and to 99.8 ± 1.8 one year after surgery. The overall quality of life score improved from 30 ± 18 to 88 ± 8.8 one year after surgery. Conclusions: These results show that this approach significantly shortened the time needed for the athletes to return to sports at the same level as before the surgery (athletes returned to sports in approximately 2.5-3 months). The mean follow-up time was 19.75 months. This technique can be considered a viable option for the treatment of cartilage injuries in professional athletes, allowing them to return to play more quickly in a safe and healthy way.

Abstract
OBJECTIVE To perform a scoping literature review evaluating and reporting on outcomes and return to pivoting sports after cartilage procedures. For this review, the following cartilage procedures were evaluated: microfracture, osteochondral autograft transplantation (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI). DESIGN The scoping review incorporated articles identified using PubMed (MEDLINE), CINAHL, and Cochrane Central Register of Controlled Trials. Screening of reference lists of included studies and forward citation tracking were performed to identify additional studies. Reported on return to pivoting sports after cartilage surgery written in English language. RESULTS Sixteen studies fulfilled the inclusion criteria. The return to sports (RTS) rates after microfracture ranged from 44% to 83%, and to preinjury level from 25% to 75%. The RTS rates after OAT ranged from 87% to 100%, and to preinjury level from 67% to 93%. The RTS rates after OCA ranged from 77% to 80%, and to preinjury level 64%. The RTS rates after ACI ranged from 33% to 96%, and to preinjury level from 26% to 67%. CONCLUSIONS There was a high heterogeneity and range in rates of RTS in athletes participating in pivoting sports. Most studies reported high rates of RTS; however, return to preinjury level was lower. These data may be important to clinicians in shared decision making on the type of procedure to be performed and counseling pivoting sports athletes on prognosis and expected RTS rates.

Abstract
BACKGROUND Wrist injuries are common in sports and can result in prolonged time missed from playing. This study aimed to determine in Major League Baseball-players after arthroscopic wrist surgery the return-to-sport (RTS) rate, postoperative career length, and changes in performance compared with preoperative statistics and matched controls. METHODS Major League Baseball players who underwent arthroscopic wrist surgery from 1990 to 2019 were identified. Demographic and performance data were collected for each player, and matched controls were identified. Comparisons were made via paired samples Student t tests. RESULTS Twenty-six players (27 surgeries) were identified. The average age of included players was 28.9 ± 2.9 years with an average professional experience of 5.2 ± 3.4 years. Eighty-four percent of players returned to sport, with an average RTS time of 5.0 ± 2.7 months. A statistically significant (P < .05) decrease was seen in preoperative and postoperative runs scored per season (95.6 ± 91.3 vs 41.0 ± 29.5), batting average (BA) (0.270 ± 0.024 vs 0.240 ± 0.036), and average wins above replacement (WAR) (1.5 ± 1.1 vs 0.8 ± 0.9). CONCLUSION Major League Baseball players who underwent arthroscopic wrist surgery had an RTS rate of 84% at a mean time of 5.0 months. There was no significant difference in performance statistics between cases postoperatively and matched controls overall, with some differences in performance found when categorized by position. However, a significant decrease in performance among case players was observed between preoperative and postoperative performance, including runs per season, BA, and WAR.

Abstract
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.

Abstract
Background: Thoracic outlet syndrome (TOS) is a rare injury that affects Major League
Baseball (MLB) pitchers and is often corrected with surgical resection of
the first rib. There are limited return-to-play (RTP) data for this surgery
in MLB pitchers. Hypothesis: It was hypothesized that MLB pitchers who undergo first rib resection for TOS
will show (1) a high rate of RTP, (2) no difference in postoperative career
length compared with controls, (3) no difference in pre- and postoperative
performance, and (4) no difference in postoperative performance compared
with controls. Study Design: Cohort study; Level of evidence, 3. Methods: This retrospective cohort study evaluated MLB pitchers with neurogenic or
vascular TOS who underwent rib resection surgery between January 1, 2001,
and December 31, 2019. Players were identified through public injury reports
from press releases, the MLB website, MLB team injury reports, and blogs. A
demographics- and performance-matched control group was generated for
comparison. Each player in the control group was given an index year that
corresponded to the surgery year of the case group. Performance data
included innings pitched (IP), games played (GP), earned run average (ERA),
complete GP, shutouts, saves, hits, runs, home runs (HR), walks, strikeouts
(K), walks plus hits per IP (WHIP), and earned runs (ER). Results: We identified 26 MLB pitchers who underwent rib resection for neurogenic or
vascular TOS; 21 players (81%) had a successful RTP. Pitchers were 30 ± 3.6
years old at the time of surgery and had played 6.2 ± 3.5 seasons before
undergoing surgery. Average postoperative career length was 3.1 ± 2.0
seasons, with an average time from surgery to RTP being 10 ± 4.7 months.
Pitchers who RTP showed no significant differences in performance metrics
compared with controls. Players pitch 0.94 (P < .05)
more IP/GP in the season directly following RTP compared with the season
before surgical intervention. Conclusion: MLB pitchers undergoing rib resection for TOS demonstrated (1) high RTP rates
following rib resection, (2) no difference in postoperative career length
compared with controls, (3) improvement in postoperative performance, and
(4) no difference in postoperative performance compared with controls.

Abstract
Basketball is one of the students' favorite ball games, and it is also one of the most popular sports for college students to carry out after class. Especially in recent years, with the spread of NBA culture around the world and the extensive development of CUBA in domestic colleges and universities, Yao Ming has appeared in China to compete in the NBA and achieve brilliant achievements. With the increasing investment in the number of basketball venues, basketball itself, as a sport with low dependence on venues, equipment, and people, has the characteristics of economy, convenience, and remarkable sports effect compared with other sports. College students' basketball skills, basketball awareness, and love for basketball are increasing day by day. Attribute reduction algorithm is one of the core contents of knowledge discovery, which describes whether every attribute in the attribute set of information system is necessary and how to delete unnecessary knowledge. Based on the attribute reduction algorithm, this paper studies the early warning of basketball injury risk. The basketball injury can not only make athletes unable to participate in training or competition, but even cripple or lose their lives, which hinders the normal development of sports. Therefore, we should make a comprehensive and objective analysis of sports training to find out the causes of sports injuries, so as to prevent sports injuries. This algorithm takes the attribute frequency as the heuristic information and solves the attribute selection problem when the attribute frequency is the same.

Abstract
PURPOSE An investigation of arthroscopic surgery combined with coverage of the microfractured wound surface with platelet-rich plasma (PRP) and fibrin gels (FG) to treat knee cartilage defects. METHODS Between February 2017 and February 2020, 145 patients with knee cartilage defects were treated. Only isolated full-thickness cartilage defects were included, and 28 patients (12 men and 16 women) were included in this study. They were all treated with arthroscopic surgery on subchondral bones, filled with PRP and thrombin, and sealed with FG. The knee pain visual analogue scale (VAS) scores were measured after the patients climbed ten stairs up and down, and the Western Ontario and McMaster Universities osteoarthritis index and the area of cartilage defects were measured through the pre-operative and post-operative follow-up. The complication incidences were also observed. RESULTS All patients were followed up for ten to 15 months (median 12 months). The knee pain VAS scores decreased from 6.57 ± 1.07 pre-operatively to 2.09 ± 1.35 at the last follow-up. The WOMAC osteoarthritis index decreased from 44.32 ± 3.95 (mean ± sd) pre-operatively to 16.57 ± 2.20 by the last follow-up. The cartilage defect decreased from 2.93 ± 0.65 cm2 pre-operatively to 1.09 ± 0.69 cm2 at the last follow-up. All scores showed statistically significant improvements after surgery (p < 0.05). No complications were observed. CONCLUSION The combination therapy of arthroscopic surgery and covering the microfractured wound surface with PRP and FG can repair knee cartilage defects, relieve pain, and improve function, and is a safe and effective treatment.

Abstract
BACKGROUND Numerous studies have reported the incidence and outcomes of injuries in the men's and women's National Basketball Association (NBA and WNBA, respectively). PURPOSE To synthesize published data regarding the incidence and outcomes of all injuries in the NBA and WNBA in a comprehensive review. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched 3 electronic databases (PubMed, MEDLINE, Embase) for studies of all levels of evidence since 1990 pertaining to injuries sustained by active players in the NBA and WNBA. Studies were excluded if the cohort of interest included ≤3 active players. RESULTS The initial search of the 3 databases yielded 1253 unique studies, of which 49 met final inclusion criteria for this review. Only 4 studies included athletes in the WNBA. Based on the mean annual incidence, the 5 most common orthopaedic sports injuries sustained in the NBA were concussions (9.5-14.9 per year), fractures of the hand (3.5-5.5 per year), lower extremity stress fractures (4.8 per year), meniscal tears (2.3-3.3 per year), and anterior cruciate ligament tears (1.5-2.6 per year). Cartilage defects treated using microfracture, Achilles tendon ruptures, and anterior cruciate ligament injuries were 3 injuries that led to significant reductions in performance measurements after injury. CONCLUSION With advances in sports technology and statistical analysis, there is rapidly growing interest in injuries among professional basketball athletes. High-quality prospective studies are needed to understand the prevalence and effect of injuries on player performance and career length. This information can inform preventative and treatment measures taken by health care providers to protect players and guide safe return to play at a high level.

Abstract
BACKGROUND Surgery aims to stimulate healing and enable a safe return to sport in athletes with symptomatic cartilage lesions of the knee. Timing of postoperative weightbearing is crucial, balancing a stimulation of the healing and avoiding reinjury.To explore current concepts of timing to partial and full weightbearing and rate of return to sport in athletes after articular cartilage surgery of the knee.Systematic Review of studies with level of evidence I-III. METHODS Four databases (Pubmed, Web of Science, Scopus and Embase) were searched using a predetermined keyword strategy. Two independent reviewers screened results according to inclusion and exclusion criteria. Modified Coleman Methodology Score (mCMS) was used for the quality assessment. RESULTS 5294 records were found. Data from ten studies was extracted after duplicate removal, title and abstract screening and full-text evaluation. Eight of the ten studies included a detailed rehabilitation protocol, including 336 out of a total athletic population of 401. 62% began partial weightbearing (PWB) 1-2 weeks postoperatively, while 38% began within 3-4 weeks. The studies that had a later PWB all returned to full weightbearing (FWB) within 6-8 weeks. One study with early PWB returned to early FWB, while the other two returned 10-12 weeks postoperatively. "Return to Sport" (RTS) was the most common reported outcome measure, with most studies reporting RTS at 80% or higher. CONCLUSION There is no clear evidence that the timing of weightbearing (WB) affects the outcome and return to sport in athletes after surgery for focal full-thickness cartilage lesions of the knee. On the other hand, there seems to be no adverse effects in adopting an early WB strategy, currently defined differently by different authors. Further studies directly comparing the timing of WB for specific surgical procedures in athletes and with relevant control groups is recommended. There is a need for a consensus in regard to more exactly defining "early" vs "late" weightbearing in relation to a universal and precisely defined state of healing.

Abstract
Articular cartilage injuries of the knee are being observed with increasing frequency in athletes and have proven to be difficult to treat given the limited regenerative ability of cartilage and the potential for progressive joint degeneration. A wide range of surgical treatments such as microfracture, autologous chondrocyte implantation, and osteochondral autograft and allograft have demonstrated promising results in these high-demand individuals. These procedures permit healing of cartilage defects while decreasing pain and restoring function with patient-reported outcomes demonstrating significant improvement at short-, mid-, and long-term follow-up. Most athletes are able to return to play after cartilage restoration of the knee, regardless of the surgical technique used. Although there is a large degree of heterogeneity across the literature and no consensus as to the optimal technique, osteochondral autograft transfer seems to offer the highest rate of return to sport and return to play at preinjury level. However, autologous chondrocyte implantation and osteochondral allograft transplantation are often used for larger defects or salvage after previous procedures, so results may be confounded. In addition, a multitude of factors including patient history, characteristics of the chondral lesion, and postoperative management may affect functional outcomes in athletes.

Abstract
BACKGROUND Single-legged hop tests are frequently used in substantiating return to sport decisions following lower extremity injury. Evidence for using the non-injured leg as a reference for the injured leg in the return to sport decision-making at the criterion-based point of return to sport following lower extremity injury is lacking. PURPOSE To compare absolute values in single-legged hop tests between the non-injured leg of athletes returning to high-impact sports after lower extremity injury and the matched leg of healthy athletes. STUDY DESIGN Cross-sectional study. METHODS One hundred and sixty-nine athletes returning to high-impact sports after lower extremity injury and 169 matched healthy athletes executed five single-legged hop tests. Differences between athletes returning to high-impact sports after lower extremity injury and matched healthy athletes on five single-legged hop tests were analyzed using paired t-tests. RESULTS There were no statistically significant differences between the non-injured leg of athletes returning to sport and the matched leg of healthy athletes. Effect sizes ranged from 0.05 to 0.14 indicating negligible effects. CONCLUSION Clinicians can use the non-injured leg as a reference for the injured leg in single-legged hop tests for deciding on return to high-impact sports after lower extremity injuries.

Abstract
The purpose of this study was to evaluate clinical and magnetic resonance imaging (MRI) outcomes in patients who underwent cryopreserved viable osteochondral allograft (CVOCA) implantation for focal cartilage defects in the knee at a minimum of 2-years postoperatively. This is a retrospective follow-up study of twelve patients who underwent CVOCA implantation from 2013 to 2015 by a single surgeon for a International Cartilage Repair Society (ICRS) grade 3 or 4 chondral defect. Patient-reported outcome (PRO) measurements and MRI were obtained 2-years postoperatively. Collected PRO measures included: International Knee Documentation Committee (IKDC) form; Visual Analog Scale (VAS) pain score; Veterans RAND 12-Item Health Survey (VR-12); Knee Injury and Osteoarthritis Outcome Score (KOOS); and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Patients completed a standard return to work and sports/recreation survey. A blinded, fellowship-trained musculoskeletal radiologist independently evaluated each MRI to determine the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Mean follow-up was 2.1 years (2.0-2.3). There were 6 women and 6 men with a mean age of 46.2 ± 11.9 years. Mean PRO scores were: IKDC 72.6 ± 17.4; VAS 2.9 ± 2.8; WOMAC 84.2 ± 15.1; KOOS- Pain 83.8 ± 18.5, Symptoms 77.6 ± 16.0, ADL 88.0 ± 16.9, Sports/Rec 67.7 ± 33.3, QOL 54.8 ± 24.2; and VR-12 PCS 45.0 ± 8.5 and MCS 51.1 ± 9.5. The mean MOCART score was 59.5 ± 12.9. To our knowledge, this is the largest study to report clinical and MRI outcomes of CVOCA implantation in the knee. With positive functional outcomes and lack of failures at 2-year follow-up, CVOCA is a promising treatment option for focal chondral defects in the knee.

Abstract
Background: Athletes in the Women’s National Basketball Association (WNBA) and National Basketball Association (NBA) are subject to high injury rates given the physical demands of the sport. Comprehensive data regarding injury patterns and rates in these athletes are limited. Purpose: To summarize available data on orthopaedic and sports medicine–related injuries through 2020 in professional female and male basketball players. Study Design: Systematic review; Level of evidence, 4. Methods: A search was conducted using PubMed and Embase through April 5, 2020, to identify injury studies regarding WNBA and NBA players. Studies were included if the injury or surgery was considered a direct consequence of game play including musculoskeletal/orthopaedic, concussion, ophthalmologic, and craniomaxillofacial injuries. Systematic reviews, screening studies, or studies without sufficient WNBA or NBA player subgroup analysis were excluded. Results: A total of 49 studies met inclusion criteria, 43 (87.8%) of which detailed musculoskeletal injuries. The lower extremity represented 63.3% of studies. A majority (59.2%) of studies were level 4 evidence. The source of data was primarily comprehensive online search (n = 33; 67.3%), followed by official databases (n = 11; 22.4%). Only 3 studies concerned WNBA athletes compared with 47 that concerned NBA athletes. The lowest return-to-play rates were cited for Achilles tendon repairs (61.0%-79.5%). Variability in return-to-play rates existed among studies even with similar seasons studied. Conclusion: The majority of literature available on orthopaedic and sports medicine–related injuries of NBA and WNBA athletes is on the lower extremity. The injuries that had the greatest effect on return to play and performance were Achilles tendon ruptures and knee cartilage injuries treated using microfracture. The reported outcomes are limited by heterogeneity and overlapping injury studies. There are limited available data on WNBA injuries specifically.

Abstract
BACKGROUND The purpose of this study was to determine whether surgical repair of distal biceps tendon ruptures in professional football players would lead to a decrease in postinjury performance when compared to preinjury performance and control-matched peers. We also sought to define return to sport, postinjury career length, and games played per season in National Football League players following surgical repair of distal biceps tendon ruptures. METHODS Data for National Football League players who underwent surgical repair of distal biceps tendon ruptures during a 20-year time period were collected. A total of 25 cases in 22 players were included in the analysis. Matched controls based on player position, age, experience, and performance statistics were identified. Performance scores for cases and controls were calculated using a standardized scoring system specific to player position. RESULTS Of the 25 cases, 21 (84%) were able to return to sport in the National Football League. The overall 1-year survival rate of return to play in players undergoing surgical repair of distal biceps tendon ruptures was 76% and overall 2-year survival was 56%. Players who underwent surgical repair of distal biceps tendon ruptures had significantly shorter postinjury career lengths and played fewer games per season postinjury than matched controls. There was no significant difference by position in postinjury performance scores when compared to matched controls. CONCLUSION National Football League players undergoing surgical repair of distal biceps tendon ruptures have a high rate of return to sport, though many retire within the next few seasons following surgery. Players who do return to competition can be expected to perform at a level comparable to their peers.

Abstract
Background: Use of marrow-stimulating techniques to treat osteochondral lesions of the
talus (OLTs) in National Basketball Association (NBA) players is
controversial. Hypothesis: NBA players will be able to return to preinjury playing status after
treatment of OLTs by arthroscopic debridement alone without
marrow-stimulating techniques. Study Design: Cohort study; Level of evidence, 3. Methods: Between the 2000 and 2015 seasons, 10 NBA players were treated with
arthroscopic debridement of an OLT. The following performance outcomes were
compared pre- and postoperatively: seasons played, games played, games
started, minutes per game, points per game, field goals, 3-point shots,
rebounds, assists, double doubles, triple doubles, steals, blocks,
turnovers, personal fouls, assists per turnovers, steals per turnovers, NBA
rating, scoring efficiency, and shooting efficiency. In addition, the
players were compared with a matched control group using mixed effects
regression and Fisher least significant difference modeling. Results: All 10 players returned to play in the NBA after arthroscopic debridement
without microfracture or drilling of an OLT. When compared with preoperative
performance, postoperative mean points scored, assists made, and steals made
increased by 2.86 (P = .042), 0.61 (P =
.049), and 0.15 (P = .027), respectively. Only field goal
percentage decreased postoperatively when compared with matched controls;
however, this normalized by the end of the second season after surgery.
There was no statistically significant change in any of the other
performance factors when compared with matched controls. All patients
returned to basketball during the same season (n = 1) or the following
season (n = 9) if the operation was performed off-season. The mean length of
career after surgery was 4.1 years, with 5 players still playing in the
league at the time of this study. Conclusion: After arthroscopic debridement of an OLT without drilling or microfracture,
there was a high rate of return to the NBA, with improved points scored,
assists, and steals made after surgery when compared with preoperative
performance. There was no statistically significant change in any
performance factors when compared with uninjured matched controls. Lesion
size did not affect player career length. These data should be used to
manage patients’ and teams’ expectations regarding players’ ability to
return to elite levels of athletic performance after surgery of an OLT.

Abstract
BACKGROUND The present study evaluated short-term outcomes of microfracture augmented with micronized allograft cartilage matrix (BioCartilage) and platelet-rich plasma (PRP) for symptomatic focal femoral condyle or trochlea cartilage defects. METHODS Patients who underwent microfracture augmented with BioCartilage and PRP for isolated contained chondral defects were evaluated. Magnetic resonance imaging (MRI) was performed at one year postoperatively. Two-year postoperative outcomes included patient-reported outcome measures (PROMs) and rates of return-to-work and return-to-sport. RESULTS Mean age of the 10 patients who completed the study was 39.7 years (range, 19-66 years), and five (50%) were female. Mean post-debridement defect size of the five femoral condyle and five trochlea defects was 2.4 cm2 (range, 0.7-5.0 cm2). One-year postoperative MRI analysis demonstrated that two chondral lesions were <50% filled, four sites were >50% filled, two sites were completely filled, and two sites had hypertrophied. Patients experienced improvements in three PROMs at six months, one year, and two years postoperatively (p < 0.01). Postoperative Marx Activity scores revealed no decrease in activity level compared to baseline preoperatively. Nine patients (90%) returned to their pre-injury level of work by one year postoperatively and remained at that level through two years postoperatively. CONCLUSIONS Our findings suggest that small, contained focal chondral injuries in the femoral condyle and trochlea treated with a marrow stimulation procedure augmented with BioCartilage and PRP are associated with significant improvements in patient-reported outcomes at two years postoperatively. Further studies are needed to evaluate the long-term durability and imaging characteristics of this intervention. Level of evidence Therapeutic Level IV.

Abstract
Articular cartilage injury is a common source of knee pain and dysfunction. Patients in whom conservative treatment fails may benefit from surgical intervention to restore function and alleviate pain. Autologous cartilage procedures are a viable treatment modality for cartilage repair, providing comparable outcomes to osteochondral allografts while leaving the subchondral bone intact. This article discusses the senior author's method of cartilage restoration using BioCartilage (Arthrex, Naples, FL), platelet-rich plasma, and autologous cartilage collected using a designated collection device sealed with activated autologous serum.

Abstract
Objective This study aimed to determine the effect of wrist fractures on performance metrics in Major League Baseball Players after they were hit by an errant pitch. Methods Players who sustained wrist fractures after being struck by a pitch were identified and changes in performance metrics were calculated. Results In both the short- and medium-term analysis, there were no significant differences in all pre- and post-injury offensive statistics following return to play. Conclusion Wrist fractures sustained after being struck by an errant pitch do not significantly impact professional baseball player performance if the player is able to return to sport.

Abstract
The purpose of this study was to determine the (1) return-to-sport rate for National Football League (NFL) players following femoroacetabular impingement surgery, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. National Football League athletes who underwent hip arthroscopy for femoroacetabular impingement and matched controls were identified. A Bonferroni correction was used to control for multiple comparisons, with statistical significance set at P≤.007. Fifty-five players (63 surgeries) were analyzed (mean age, 27.5±3.4 years; mean years in NFL at time of surgery, 4.7±2.9). Forty-seven (53 surgeries, 84.1%) NFL players returned to sport at a mean of 6.7±3.8 months following surgery. There was no difference (P>.007) in the mean career length of players in the control group (3.7±2.2 years) vs players who underwent hip arthroscopy (3.5±2.1 years). There was no difference (P>.007) in mean games played per season of players in the control group (12.5±3.1) vs those who underwent hip arthroscopy (12.1±4.0). Quarterbacks had significantly better postoperative performance scores when compared with post-index matched controls (P=.007). The return-to-sport rate is high for NFL athletes after hip arthroscopy for femoroacetabular impingement. There were similar games per season and career lengths postoperatively compared with preoperatively and matched controls. Quarterbacks had significantly better postoperative performance when compared with matched controls. All other positions had similar postoperative performance compared with preoperatively and matched controls. [Orthopedics. 2019; 42(5):e423-e429.].

Abstract
Background: Acute ruptures of the ulnar collateral ligament (UCL) of the thumb are common injuries in sports. Surgical repair of complete tears has yielded excellent results in elite athletes. Methods: National Football League (NFL) players who underwent thumb UCL surgery and matched controls were identified. Demographic and performance data were collected. Performance scores were calculated using a standardized scoring system. Return to sport (RTS) in the NFL was defined as playing in at least 1 NFL game after thumb UCL surgery. Comparisons between case and control groups and preoperative and postoperative time points were made using paired-samples Student t tests. Results: Twenty-three players were identified (mean age: 28.8 ± 3.4 years and mean experience in the NFL: 5.9 ± 3.4 years). Twenty-two players (95.7%) were able to return to sport in the NFL at an average of 132.2 ± 126.1 days. The overall 1-year NFL career survival rate of players undergoing thumb UCL surgery was 87.0%. There was not a statistically significant decrease in games per season and career length for any position following surgery. No positions had a significant difference in postoperative performance when compared with preoperative performance, and there was no significant performance difference postoperatively when compared with matched controls. Conclusions: There is a high rate of RTS in the NFL following thumb UCL surgery. Players who underwent thumb UCL surgery played in a similar number of games per season and had similar career lengths in the NFL as controls. No position group had any significant postoperative performance score differences when compared with postindex matched controls.

Abstract
PURPOSE To determine (1) return-to-sport rates for National Football League, Major League Baseball, National Basketball Association, and National Hockey League (NHL) athletes after hip arthroscopy for femoroacetabular impingement syndrome, (2) postoperative return-to-sport rate differences between sports, (3) differences in postoperative career length and games per season, (4) differences in preoperative and postoperative performance, and (5) postoperative performance compared with that of matched control players. METHODS Professional athletes who underwent hip arthroscopy for femoroacetabular impingement syndrome were identified. Matched control players were identified by position, age, experience, and performance. Return to sport was defined as playing in at least 1 game after surgery. Continuous variables for each group were compared by using a 2-tailed paired-samples Student t test or χ2 test. A Bonferroni correction was used to control for multiple comparisons with statistical significance defined by a P value < .002. RESULTS One hundred seventy-two players (86.4%) (mean age, 28.8 ± 5.2 years) were able to return to sport at an average of 7.1 ± 4.1 months. Athletes played 3.5 ± 2.4 years after surgery without significant differences between sports (P > .002). NHL players who underwent surgery played significantly fewer years (4.4 vs 3.3 years) (P < .001) and fewer games per season (4 fewer games) (P <.001) after surgery compared with control players. NHL players also had a significant decrease in performance after surgery compared with their performance before surgery (P < .001). In National Football League, Major League Baseball, and National Basketball Association athletes, no significant differences were found in games per season, career length, or preoperative performance compared with postoperative performance and performance of matched control players (P > .002). CONCLUSION The RTS rate for professional athletes after surgery for femoroacetabular impingement syndrome is high. Only NHL athletes had significantly shorter careers and played significantly fewer games per season compared with matched control players, with no difference between sports. NHL athletes had significantly worse postoperative performance compared with preoperative performance, with all other sports demonstrating a career-related decline similar to that of matched control players.

Abstract
The National Basketball Association (NBA) has an extremely demanding competition schedule, requiring its athletes to compete in 82 regular-season games over a 6-mo period (∼3.4 games/wk). Despite the demanding schedule and high value of athletes, there is little public information on the specific game and training demands required to compete in the NBA. Although provisions in the NBA collective-bargaining agreement allow for research designed to improve player health and broaden medical knowledge, such information is sparse in the available literature. In relation to the physical demands of the NBA, the current lack of information likely results from multiple factors including limited understanding of (basketball-related) emerging technologies, impact of specific league rules, and steps taken to protect players in the age of Big Data. This article explores current limitations in describing specific game/training demands in the NBA and provides perspectives on how some of these challenges may be overcome. The authors propose that future collaborations between league entities, NBA clubs, commercial partners, and outside research institutions will enhance understanding of the physical demands in the NBA (and other health- and performance-related areas). More detailed understanding of physical demands (games, practices, and travel) and other health-related areas can augment player-centered decision making, leading to enhanced player care, increased availability, and improved physical performance.

Abstract
Hyaline articular cartilage is critical for the normal functioning of the knee joint. Untreated focal cartilage defects have the potential to rapidly progress to diffuse osteoarthritis. Over the last several decades, a variety of interventions aiming at preserving articular cartilage and preventing osteoarthritis have been investigated. Reparative cartilage procedures, such as microfracture, penetrate the subchondral bone plate in effort to fill focal cartilage defects with marrow elements and stimulate fibrocartilaginous repair. In contrast, restorative cartilage procedures aim to replace the defective articular surface with autologous or allogeneic hyaline cartilage. This review focuses on the preservation of articular cartilage, and discusses the current reparative and restorative surgical techniques available for treating focal cartilage defects.

Abstract
BACKGROUND Previous studies have demonstrated that hip arthroscopy is an effective treatment for symptomatic femoroacetabular impingement (FAI) in professional athletes across a variety of sports. However, the return-to-play rates and postoperative performance of elite basketball players after hip arthroscopy are currently unknown. PURPOSE To determine return-to-play rates and postoperative performance among professional basketball athletes after hip arthroscopy. STUDY DESIGN Case series; Level of evidence, 3. METHODS Eighteen professional basketball players underwent hip arthroscopy (24 hips) for symptomatic FAI between 2001 and 2016 by a single surgeon. Return to play was defined as competing in a single professional game of equal level after surgery. Data were retrospectively obtained for each player from basketball-reference.com , ESPN.com , eurobasket.com, and individual team websites. Matched controls were selected from the websites to compare performances. RESULTS The mean age at the time of surgery was 25.6 years, and the mean body mass index was 24.4 kg/m2. All players returned to their previous levels of competition, with a mean number of 4 seasons played after surgery (median, 3; range, 1-12). The mean ± SD time between the date of surgery and return to a professional game was 7.1 ± 4.4 months. There was no change in player efficiency rating when pre- and postinjury performance were compared. When compared with controls, players undergoing surgery also had no significant decline in player efficiency rating. CONCLUSION Elite basketball athletes who undergo hip arthroscopy for the treatment of FAI return to their presurgical levels of competition at a high rate. These athletes demonstrate no significant overall decrease in performance upon their return to play.

Abstract
BACKGROUND Forearm fractures are one of the most common upper extremity injuries requiring surgery in professional football. Surgical fixation of forearm fractures may speed recovery and decrease games missed in football. METHODS National Football League (NFL) players who underwent forearm fracture open reduction and internal fixation (ORIF) were identified. Matched controls (position, age, experience, performance) were identified. Control and case performance scores were calculated using a standardized scoring system. Return to sport (RTS) in the NFL was defined as playing in a single NFL game after surgery. Comparisons between case and control groups and preoperative and postoperative time points were made using paired-samples Student t tests. RESULTS Thirty-six surgeries were analyzed following ORIF. Thirty-three were able to RTS in the NFL at an average of 152.1 + 129.8 days. Controls had a significantly longer NFL career ( P < .001) and played in significantly more games per season ( P = .026) than players who underwent surgery. There was a significant ( P = .013) decrease in games/season for DBs following surgery. No significant difference was seen in postoperative performance scores compared with preoperative scores among any positions, nor in postoperative and postindex performance scores compared with matched controls. CONCLUSION There is a high rate of RTS in the NFL following forearm fracture ORIF. Following surgery, players' careers were 1 year shorter and played nearly 2 fewer games per season than matched controls. Games per season following surgery was significantly lower among DBs when compared with presurgery. Postoperative performance scores were not significantly different compared with preoperative and when compared with matched controls.

Abstract
Background: Patellar tendon tears impart potentially debilitating sequelae among professional basketball athletes. Hypothesis: Professional basketball athletes with patellar tendon tears have decreased return-to-play performance in seasons after injury compared with preinjury statistics. Study Design: Case series; Level of evidence, 4. Methods: Patellar tendon tears among National Basketball Association (NBA) athletes from the 1999-2000 to 2014-2015 seasons were identified. Player performance statistics for players who underwent operative patellar tendon repair were compared from 1 season before injury to 1 season after injury and 2 seasons before injury to 2 seasons after injury using the primary outcome of player efficiency rating (PER). Secondary performance outcomes were also analyzed. Results: A total of 13 patellar tendon tears (10 complete, 3 partial) were identified among 12 NBA athletes. Three players (25%) did not return to play in the NBA. No significant differences were found in PER in comparisons of 1 season before and after injury (16.6 ± 1.5 vs 14.3 ± 1.7; P = .20) or in comparisons of 2 seasons before and after injury (15.8 ± 0.8 vs 6.3 ± 2.3; P = .49). Diminished performance outcomes were noted for total minutes played (2598 ± 100 vs 1695 ± 78; P = .01), games played (74.8 ± 1.9 vs 60.5 ± 1.4; P = .04), and minutes per game (34.8 ± 1.5 vs 28.2 ± 1.8; P = .02) in comparisons of 1 season before and after injury. Total minutes played per season (2491 ± 190 vs 799 ± 280; P = .045) decreased in comparisons of 2 seasons before and after injury. Conclusion: Patellar tendon tears were not associated with diminished efficiency-adjusted performance, as measured by PER, games played, minutes per game played, points per 36 minutes, and rebounds per 36 minutes. However, decreases in total minutes played were observed following patellar tendon tear. Orthopaedic surgeons may be better prepared to counsel basketball athlete patients with patellar tendon tear given these findings.

Abstract
BACKGROUND Hip arthroscopy has been shown to be effective for management of symptomatic femoroacetabular impingement (FAI) in professional athletes; however, it is unclear how hip arthroscopy affects career length and performance when professional baseball players return to play. PURPOSE To determine the career length, performance, and return-to-play rates of professional baseball players after undergoing arthroscopy for symptomatic FAI. STUDY DESIGN Case series; Level of evidence, 4. METHODS Forty-four professional baseball players (51 hips) underwent hip arthroscopy for FAI between 2000 and 2015 by a single surgeon. Data were retrieved for each player from MLB.com , MiLB.com , Baseballreference.com , and individual team websites. Age, surgical procedure, and intraoperative findings were also used in analysis. Return to play was defined as playing in a preseason or regular season major or minor league game after arthroscopy. Career length was measured as total years played before and after arthroscopy. Performance measures included earned run average for pitchers, batting average for position players, and games played for all players. RESULTS Of the 44 players, there were 21 pitchers and 23 position players. Ninety-five percent (n = 42) were able to return to professional baseball after hip arthroscopy. The mean career length for all players was 9.5 years. The mean career length after return to play was 3.6 seasons (range, 1-14 seasons). Pitchers had a mean career length of 8.7 years (3.3 after surgery), and position players averaged a career length of 10 years (3.9 after surgery). There were no differences in performance measures between preinjury and postoperative values. CONCLUSION Professional baseball players undergoing hip arthroscopy for FAI returned to sport and had similar performance as they did before injury. The average career length was 9.5 years. In our study cohort, more pitchers than position players underwent hip arthroscopy. Hip arthroscopy appears to be an effective surgical intervention, allowing for return to play after complete recovery.

Abstract
Background: Osteochondral allograft transplantation (OCA) is a recognized option for full-thickness articular cartilage defects of the knee, especially in the setting of large lesions or those involving the subchondral bone. Previous heterogenous studies of athletes have shown a 75% to 79% rate of return to play after the procedure. Purpose: To define return-to-play rates in a cohort of elite collegiate and professional basketball players following osteochondral allograft of the knee. Study Design: Case series; Level of evidence, 4. Methods: Prospectively collected data from an institutional cartilage repair registry were retrospectively reviewed. Patients were eligible for inclusion if they were collegiate or professional basketball players at the time of surgery. Patient demographics, lesion size and location, and surgical details were collected. Postoperative magnetic resonance imaging scans were scored with the OCAMRISS system. Time to return to play and pre- versus postoperative player performance were determined with publicly available internet resources. Results: Eleven athletes (4 professional, 7 collegiate) with a total of 14 treated lesions (1 to the medial femoral condyle, 6 to the lateral femoral condyle, 5 to the trochlea, and 2 to the patella) were eligible for study inclusion. Mean lesion size was 509 mm2. All patients underwent OCA through an arthrotomy, with fresh grafts. The overall rate of return to play at the same level of competition was 80%. Median time to return to play was 14 months (range, 6-26 months). Among players with available statistics, there was no significant reduction in any performance category. Conclusion: OCA in elite basketball players results in an 80% return to previous level of competition, which is consistent with previous reports of athletes playing other sports. Osteochondral allografting is a reasonable option to consider for full-thickness cartilage lesions of the knee, even for elite jumping athletes.

Abstract
BACKGROUND The anterior bundle of the medial ulnar collateral ligament (UCL) is the primary restraint to valgus stress at the elbow and is often injured among overhead throwing athletes. Despite prevention strategies, injuries to the elbow UCL are on the rise. PURPOSE To determine (1) the return-to-sport (RTS) rate of Major League Baseball (MLB) position players after elbow medial UCL reconstruction, (2) postoperative career length and games per season, (3) pre- and postoperative performance, (4) postoperative performance versus matched control players, and (5) whether position players changed positions after UCL reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS MLB players who underwent elbow UCL reconstruction were identified (cases). Demographic and performance data were collected for each player. Matched controls were identified. RTS in MLB was defined as playing in at least 1 MLB game after UCL reconstruction. Comparisons between case and control groups and pre- and postoperative time points were made via paired samples Student t tests. RESULTS Thirty-three players (34 surgical procedures) were identified with a mean ± SD age of 30.2 ± 4.2 years and a mean experience in the MLB of 6.3 ± 3.9 years at the time of surgery. Twenty-eight players (84.8%) were able to RTS in MLB at a mean 336.9 ± 121.8 days. However, players ≥30 years old demonstrated a significantly lower RTS rate (53.3%) than players <30 years old (89.4%; P < .05). Catchers had a significantly shorter postoperative career length (2.8 ± 1.8 years) versus matched controls (6.1 ± 1.9 years; P < .05). Outfielders had a significantly lower wins above replacement postoperatively (0.8 ± 0.7) versus preoperatively (1.5 ± 1.1; P < .05). There were no performance differences between cases and matched controls. Twelve players (48%) returned to a different position postoperatively. CONCLUSION The RTS rate for MLB position players after elbow UCL reconstruction is similar to that of pitchers. Catchers had a significantly shorter career length than that of matched controls. Outfielders performed worse postoperatively versus preoperatively. There is a high rate of position change after Tommy John surgery for infielders and outfielders.

Abstract
BACKGROUND We sought to determine whether professional baseball positional players who underwent medial ulnar collateral ligament (MUCL) reconstruction demonstrate decreases in performance on return to competition compared with preoperative performance metrics and their control-matched peers. METHODS Data for 35 Major League Baseball positional players who underwent MUCL reconstruction during 31 seasons were obtained. Twenty-six players met inclusion criteria. Individual statistics for the 2 seasons immediately before injury and the 2 seasons after injury included wins above replacement (WAR), on-base plus slugging (OPS), and isolated power (ISO). Twenty-six controls matched by player position, age, plate appearances, and performance statistics were identified. RESULTS Of the 35 athletes who underwent surgery, 7 did not return to their preinjury level of competition (return to play rate of 80%). In comparing preinjury with postinjury statistics, players exhibited a significant decrease in plate appearances, at-bats, and WAR 2 seasons after injury but did not demonstrate declines in WAR 1 season after injury. Compared with matched controls, athletes who underwent MUCL reconstruction did not demonstrate significant decline in statistical performance, including OPS, WAR, and ISO, after return to play from surgery. Of all positional players, catchers undergoing surgery demonstrated lowest rates of return to play (56%) along with statistically significant decreases in home run rate, runs batted in, and ISO. CONCLUSION Major League Baseball positional players undergoing MUCL reconstruction can reasonably expect to return to their preinjury level of competition and performance after surgery compared with their peers. Positional players return to play at a rate comparable to that of pitchers; catchers may experience more difficultly in returning to preinjury levels of play.

Abstract
Background Acute ruptures of the ulnar collateral ligament (UCL) of the thumb are common injuries in sports. Surgical repair has yielded excellent results and high return-to-sport (RTS) rates in elite athletes. Purpose To determine (1) the RTS rate in Major League Baseball (MLB) players following thumb UCL repair, (2) postoperative career length and games played per season, (3) pre- and postoperative performance, (4) postoperative performance compared with matched control players, and (5) whether dominant and nondominant hand injuries respond differently. Study Design Cohort study; Level of evidence, 3. Methods MLB players who underwent thumb UCL surgery from August 3, 1987, to September 6, 2016, were identified. Demographic and performance data were collected for each player, and matched controls were identified. RTS in the MLB was defined as playing in at least 1 MLB game after surgery. Comparisons were made by use of paired-samples Student t tests. Results Twenty-one players were identified, with a mean ± SD age of 31.7 ± 3.9 years and mean experience in the MLB of 8.6 ± 3.3 years at time of surgery. Twenty-one players (100%) achieved RTS in the MLB at a mean 120.0 ± 75.9 days. No significant decrease was found in games per season or career length for any position following surgery. Infielders had a significantly lower rate of postoperative wins above replacement (WAR) compared with preoperatively (P = .006), but no significant differences in postoperative performance score were found compared with controls after the index date. No significant difference was found for performance between players undergoing surgery on their dominant hand and those who had surgery on their nondominant (glove) hand compared with controls. Conclusion In this study, 100% of MLB players achieved RTS after thumb UCL repair, with in-season players returning at a mean of 8 weeks. Players who underwent thumb UCL repair played in a similar number of games per season and had similar career lengths in the MLB as controls. Infielders had a significantly lower postoperative WAR compared with preoperatively, but no significant postoperative performance score differences were noted when infielders were compared with post-index date matched controls. No significant performance differences were noted with regard to surgery on dominant and nondominant hands.

Abstract
Background: Ulnar collateral ligament reconstruction (UCLR) has become an increasingly common procedure among Major League Baseball (MLB) pitchers. The long-term effects of this procedure on the career of an MLB pitcher are largely unknown. Purpose/Hypothesis: The purpose of this study was to determine why and when MLB pitchers who underwent UCLR during their careers retired from baseball as compared with controls. We hypothesized that pitchers who underwent UCLR are no more likely than control pitchers to retire from elbow or shoulder problems. Study Design: Cross-sectional study; Level of evidence, 3. Methods: All MLB pitchers who underwent UCLR were identified through publicly available data. A cohort of pitchers who did not undergo UCLR were matched to pitchers with a history of UCLR, based on sex, age, draft year, and draft round. Of those who were no longer pitching in the MLB, the reason for retirement was determined. Reason for retirement and length of career following UCLR (surgical group) and index year (control group) were determined and compared through prior studies via the MLB HITS database, MLB team websites, and publicly available internet-based injury reports. Results: Overall, 153 MLB pitchers who underwent UCLR between 1974 and 2015 are currently retired. Mean ± SD time to retirement was 4.4 ± 4.7 years (range, 0-26 years) after the index year in the control group and 4.4 ± 3.5 years (range, 0-15 years) after surgery in the UCLR group (P = .388). Patients who were status post-UCLR were significantly more likely to be released during the season (34 of 144, 23.6%) than were players who were not status post-UCLR (14 of 144, 9.7%) (P = .002). Shoulder injury as a reason for retirement was more common in the control group than the UCLR group (P = .011). Elbow injury as a reason for retirement was not more common in either group (P = .379). Leg injury as a reason for retirement was more common in the control group (P = .013). Performance as a reason for retirement was more common in the UCLR group than the control group (P < .001). Conclusion: MLB pitchers who have undergone UCLR are no more likely to retire from shoulder or elbow injuries than are those who have not undergone UCLR. MLB career length was similar between pitchers with and without a history of UCLR.

Abstract
PURPOSE Optimal surgical treatment of chondral defects in an athletic population remains highly controversial and has yet to be determined. The purpose of this review was to (1) report data on return to sport and (2) compare activity and functional outcome measures following various cartilage restoration techniques. METHODS A comprehensive review was performed for studies with return-to-sport outcomes after microfracture (MFX), osteochondral autograft transfer (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI). All studies containing return-to-sport participation with minimum 2-year post-operative activity-based outcomes were included. A meta-analysis comparing rate of return to sport between each surgical intervention was conducted using a random-effects model. RESULTS Forty-four studies met inclusion criteria (18 Level I/II, 26 Level III/IV). In total, 2549 patients were included (1756 M, 793 F) with an average age of 35 years and follow-up of 47 months. Return to sport at some level was 76 % overall, with highest rates of return after OAT (93 %), followed by OCA (88 %), ACI (82 %), and MFX (58 %). Osteochondral autograft transfer showed the fastest return to sports (5.2 ± 1.8 months) compared to 9.1 ± 2.2 months for MFX, 9.6 ± 3.0 months for OCA and 11.8 ± 3.8 months for ACI (P < 0.001). A meta-regression was conducted due to heterogeneity in preoperative factors such as patient age, lesion size, and preoperative Tegner score. None of these factors were found to be significant determinants for rate of return to sport. CONCLUSION In conclusion, in this meta-analysis of 2549 athletes, cartilage restoration surgery had a 76 % return to sport at mid-term follow-up. Osteochondral autograft transfer offered a faster recovery and appeared to have a higher rate of return to preinjury athletics, but heterogeneity in lesion size, athlete age, and concomitant surgical procedures are important factors to consider when assessing individual athletes. This study reports on the rate of return to sport in athletes undergoing various procedures for symptomatic chondral defects. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To identify the impact of anterior cruciate ligament (ACL) reconstruction on performance and career longevity for National Basketball Association (NBA) players. METHODS Seventy-nine players (80 knees) with acute ACL tears in the NBA between the 1984-2014 seasons, and 112 age, height, weight, and performance-matched controls were identified. Pre- and post-injury performance outcomes including seasons played, games played, games started, minutes per game, points per game, field goals, 3-point shots, rebounds, assists, steals, blocks, turnovers, personal fouls, usage percentage and player efficiency ratings were compared between cases and controls using independent samples t tests and Fisher's exact tests. RESULTS Sixty-eight of seventy-nine players (86.1 %) returned to play in the NBA following ACL reconstruction. Mean length of post-operative play was 1.84 years shorter than matched controls (P = 0.001). There was a significantly higher rate of attrition from professional basketball for players with a history of ACL reconstruction (P = 0.014). In the first full season following surgery, players started in 15.5 fewer games (P = 0.001), they played in 17.3 fewer games (P < 0.001), and had combined player efficiency ratings 2.35 points lower (P = 0.001) when compared to matched controls. Over the length of their careers, players competed in 22.2 fewer games per season (P = 0.009). CONCLUSIONS There is a high rate of return to sport in the NBA following ACL reconstruction, although playing time, games played, player efficiency ratings and career lengths are significantly impacted in the post-operative period. These data should be used to manage patients' expectations regarding their abilities to return to elite levels of athletic performance.

Abstract
BACKGROUND Achilles tendon injuries are common in sports, including football. The purpose of this study was to determine (1) return-to-sport rate in National Football League (NFL) players following Achilles tendon repair, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. METHODS Publicly available records were used to identify NFL players who underwent Achilles tendon repair and matched controls were identified. Ninety-five players (98 surgeries) were analyzed (mean age 28.2 ± 2.8 years; mean 5.5 ± 2 .8 years in NFL at time of surgery). Demographic and performance data were collected. Comparisons between case and control groups and preoperative and postoperative time points were made using paired-samples Student t tests. RESULTS Seventy-one (72.4%) players were able to return to sport in the NFL at a mean of 339.8 ± 84.8 days following surgery. Thirty-one (32%) Achilles tendon repairs were performed during training camp or preseason. Controls (3.6 ± 2.1 years) had a significantly longer NFL career ( P < .05) than players who underwent Achilles tendon repair (2.7 ± 2.1 years). There was no significant difference in games per season in subsequent seasons following surgery compared with controls. Postoperative performance scores were significantly worse ( P < .05) for running backs (RBs) (n = 4) and linebackers (LBs) (n = 12) compared to preoperative scores. LBs had significantly worse postoperative performance scores when compared to matched controls ( P < .05). CONCLUSION Following Achilles tendon repair, less than 75% of players returned to the NFL. Postoperative career length was 1 season shorter than matched controls. No difference was observed in the number of games per season played compared to matched controls. Postoperative performance scores were significantly worse for RBs and LBs compared to preoperative and LBs had significantly worse postoperative performance when compared to matched controls. LEVEL OF EVIDENCE Level III, retrospective comparative series.

Abstract
Clavicle fractures are often seen in contact sports. The purpose of this study was to determine (1) return-to-sport (RTS) rate of National Football League (NFL) players following nonoperative treatment of clavicle fractures, (2) posttreatment career length and games per season, (3) pre- and posttreatment performance, and (4) posttreatment performance compared with control players matched by position, age, years of experience, and performance. Public records were used to identify NFL players who underwent nonoperative treatment of clavicle fractures. Demographic and performance data were collected for each player. Matched controls (position, age, experience, and performance) were identified. Control and case performance scores were calculated using a standardized scoring system. Return to sport was defined as playing a minimum of 1 game after treatment. Comparisons between the 2 groups and pre- and posttreatment time points were made using paired-samples Student's t tests. Thirty players (32 fractures) were analyzed. Two players fractured their contralateral clavicle. Of the players analyzed, 96.9% were able to RTS at a mean of 244.6±119.6 days. Eight players (27.6%) returned within the same season as their injury. Overall 1-year survival rate posttreatment was 93.5%. Players with nonoperative treatment had career lengths similar to those of controls (P>.05). No significant (P>.05) differences existed in demographic, performance, or games per season data between position groups for cases and matched controls pretreatment and preindex and in posttreatment compared with pretreatment performance scores. Wide receivers played fewer games per season (P=.043) following treatment. No position group had significantly worse posttreatment performance scores when compared with postindex matched controls.

Abstract
Background: Clavicle fractures are common injuries in professional football. Surgical fixation of these injuries may lead to decreased nonunion rates, improved shoulder strength, and decreased residual functional impairment. Purpose: To determine (1) return-to-sport (RTS) rate in National Football League (NFL) players after clavicle fracture open reduction and internal fixation (ORIF), (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. Study Design: Cohort study; Level of evidence, 3. Methods: Publicly available records were used to identify players who underwent surgical treatment of a clavicle fracture while playing in the NFL. Demographic and performance data were collected for each player, and matched controls were identified. Control and case performance scores were calculated using a standardized scoring system. RTS was defined as playing in 1 NFL game after surgery. Comparisons between case and control groups at preoperative and postoperative time points were made using paired-samples Student t tests. Results: Seventeen surgeries (16 players) were analyzed. Fifteen players (94.1%) were able to RTS in the NFL at a mean 211.3 ± 144.7 days postsurgery; 7 (44%) returned within the same season as their injury and subsequent fixation. The overall rate of a player’s remaining in the NFL 1 year after surgery was 88.2%. Players who underwent surgery played in a similar number of games per season and had similar career lengths in the NFL as controls (P > .05). There were no significant (P > .05) differences between cases and matched controls presurgery and preindex. There was no difference (P > .05) in postoperative performance scores or games per season compared with preoperative scores or games per season for any position. Quarterbacks (n = 3, P = .049) and running backs (n = 5, P = .039) had significantly worse postoperative performance scores when compared with postindex matched controls. Conclusion: There is a high rate of RTS in the NFL after clavicle fracture ORIF. Players who underwent clavicle fracture ORIF played in a similar number of games per season and had similar career lengths in the NFL as controls. Quarterbacks and running backs had significantly worse postoperative performance scores when compared with postindex matched controls.

Abstract
There is limited information on the potential risk factors for sustaining an anterior cruciate ligament (ACL) tear in National Basketball Association (NBA) athletes. This study evaluated 83 NBA players who sustained an ACL injury between 1984 and 2015 to determine the influence of minutes played on injury risk. Minutes played in the injury game, during the season, and over their career were assessed, along with the ability to return to play, player efficiency rating, and playing time after return. Athletes in the NBA played significantly fewer minutes before sustaining an ACL injury (17.1 minutes) than their average minutes per game that season (23.5 minutes; P<.01) or over their career (24.0 minutes; P<.01). One-third of all injuries occurred during the first quarter of the season (preseason to November). There was a 95% rate of return (78 players) to NBA competition the season following ACL injury. Players who were drafted as lottery picks (draft pick 1 to 15) or those who were starters played significantly more minutes the season following injury than those who were not (both P<.01). Players who returned to play had decreased player efficiency ratings when compared with matched controls. This study found that minutes played in a single NBA game did not contribute to the risk of sustaining an ACL injury. Although there was a high rate of return to NBA competition the season following injury, those who were elite athletes played more minutes per game than those who were not. Athletes who returned to play sustained a decrease in player efficiency ratings compared with similar athletes without ACL injury. [Orthopedics. 2017; 40(4):e658-e662.].

Abstract
Purpose To compare the macroscopic, histological, and immunohistochemical characteristics of the repair tissue of chondral defects treated with microfracture and nanofracture in an ovine model. Methods Full-thickness chondral lesions were created in the medial femoral condyle of both knees in four adult sheep and were treated with microfracture on one side and with nanofracture on the contralateral side. Chondral repair was assessed after 12 months by macroscopic, histological, and immunohistochemical analyses. Results Histological cartilage repair significantly improved in the samples treated with nanofracture for cellular morphological characteristics and cartilage architecture. The immunohistochemical analysis showed a significantly higher immunoreactivity to type II collagen in the defects treated with nanofracture. Conclusion Nanofracture provided better repair tissue than microfracture, with a more satisfactory cartilage architecture renovation and tissue having greater type II collagen content. Clinical Relevance Mesenchymal stem cell stimulation is the most frequently used primary cartilage repair procedure. Nanofracture represents a novel technique to stimulate bone marrow that results into a successful repair of chondral defects.

Abstract
Background: Recognition, diagnosis, and treatment of athletic pubalgia (AP), also known as sports hernia, once underrecognized and undertreated in professional football, are becoming more common. Surgery as the final treatment for sports hernia when nonsurgical treatment fails remains controversial. Given the money involved and popularity of the National Football League (NFL), it is important to understand surgical outcomes in this patient population. Hypothesis: After AP surgery, players would: (1) return to sport (RTS) at a greater than 90% rate, (2) play fewer games for fewer years than matched controls, (3) have no difference in performance compared with before AP surgery, and (4) have no difference in performance versus matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: Internet-based injury reports identified players who underwent AP surgery from January 1996 to August 2015. Demographic and performance data were collected for each player. A 1:1 matched control group and an index year analog were identified. Control and case performance scores were calculated using a standardized scoring system. Groups were compared using paired Student t tests. Results: Fifty-six NFL players (57 AP surgeries) were analyzed (mean age, 28.2 ± 3.1 years; mean years in NFL at surgery, 5.4 ± 3.2). Fifty-three players were able to RTS. Controls were in the NFL longer (P < .05) than players who underwent AP surgery (3.8 ± 2.4 vs 3.2 ± 2.1 years). Controls played more games per season (P < .05) than post-AP players (14.0 ± 2.3 vs 12.0 ± 3.4 games per season). There was no significant (P > .05) difference in pre- versus post-AP surgery performance scores and no significant (P > .05) difference in postoperative performance scores versus controls post-index. Conclusion: There was a high RTS rate after AP surgery without a significant difference in postoperative performance, though career length and games per season after AP surgery were significantly less than that of matched controls.

Abstract
Meniscal injuries are an extremely common cause of knee pain. Meniscal repairs performed with concomitant anterior cruciate ligament reconstruction appear to heal at a higher rate than meniscal repairs performed in isolation. This may be due in part to the release of marrow elements into the knee and the time of meniscal repair. In cases of isolated meniscal repair, some orthopedic surgeons use microfracture to release marrow elements into the joint as an adjunct to enhance meniscal healing. This study evaluated rates of meniscal tear healing with or without the performance of microfracture in a goat (Capra hircus) model. Forty castrated young adult male goats underwent either a horizontal or a longitudinal 1.0-cm meniscal tear with or without microfracture. All procedures were performed open, in a bloodless field. Meniscal tears were created in the peripheral half of the body of the medial meniscus. The goats were euthanized at 6 months, and meniscal tears were analyzed and classified as complete healing, partial healing, or no healing by direct visualization. A probe was used as an aid to evaluate and classify the meniscal tears. Twenty (87%) of 23 goat meniscal tears showed at least partial healing when performed with concomitant microfracture. Only 5 (29%) of 17 menisci showed any healing in goats that did not receive microfracture. This difference in healing rates was statistically significant (P<.001). Fifteen (65%) meniscal tears accomplished with microfracture were completely healed, whereas only 2 (12%) menisci showed complete healing without microfracture (P<.001). The results of this study suggest that the release of bone marrow elements into the knee by microfracture improves meniscal healing rates.

Abstract
Background: The aim was to determine whether players in the National Basketball Association (NBA) who sustain metacarpal fractures demonstrate decreased performance upon return to competition when compared with their performance before injury and that of their control-matched peers. Methods: Data for 32 NBA players with metacarpal fractures incurred over 11 seasons (2002-2003 to 2012-2013) were obtained from injury reports, press releases, and player profiles (www.nba.com and www.basketballreference.com). Player age, body mass index (BMI), position, shooting hand, number of years in the league, and treatment (surgical vs nonsurgical) were recorded. Individual season statistics for the 2 seasons immediately prior to injury and the 2 seasons after injury, including player efficiency rating (PER), were obtained. Thirty-two controls matched by player position, age, and performance statistics were identified. A performance comparison of the cohorts was performed. Results: Mean age at the time of injury was 27 years with an average player BMI of 24. Players had a mean 5.6 seasons of NBA experience prior to injury. There was no significant change in PER when preinjury and postinjury performances were compared. Neither injury to their shooting hand nor operative management of the fracture led to a decrease in performance during the 2 seasons after injury. When compared with matched controls, no significant decline in performance in PER the first season and second season after injury was found. Conclusion: NBA players sustaining metacarpal fractures can reasonably expect to return to their preinjury performance levels following appropriate treatment.

Abstract
BACKGROUND Ulnar collateral ligament reconstruction (UCLR) has become a common procedure among Major League Baseball (MLB) pitchers. It is unclear if a limit on innings pitched after UCLR should be instituted to prevent revision UCLR. HYPOTHESIS Number of innings pitched and number of pitches thrown after UCLR will not affect whether a pitcher requires a revision UCLR. STUDY DESIGN Descriptive laboratory study. METHODS All MLB pitchers between 1974 and 2015 who pitched at least 1 full season after UCLR were included in this study. Pitch counts and innings pitched for the first full season after UCLR as well as total pitch count and total innings pitched were recorded. Pitch counts and innings pitched were compared among players who required revision UCLR and those who did not. RESULTS Overall, 154 pitchers were included. Of these, 135 pitchers did not require revision UCLR while 19 underwent revision UCLR. No significant difference existed between pitchers who underwent revision UCLR and those who did not when comparing number of innings pitched in the season after UCLR (79.4 ± 46.7 vs 90.1 ± 58.6; P = .9016), number of pitches thrown in the season after UCLR (1233.2 ± 710.4 vs 1449.2 ± 904.1; P = .7337), number of innings pitched in the pitcher's career after UCLR (357.4 ± 312.0 vs 399.3 ± 446.4; P = .6945), and number of pitches thrown in the pitcher's career after UCLR (5632.7 ± 4583.9 vs 5674.7 ± 5755.4; P = .4789), respectively. Furthermore, no difference existed in revision rate between pitchers who pitched more or less than 180 innings in the first full season after UCLR (P = .6678). CONCLUSION The number of innings pitched and number of pitches thrown in the first full season as well as over a player's career after UCLR are not associated with an increased risk of a pitcher requiring revision UCLR.
