Abstract
CONTEXT Elbow medial ulnar collateral ligament (UCL) injuries have become increasingly common in athletes. Despite this, rehabilitation protocols appear to vary drastically, which may explain the clinical equipoise regarding optimal management. OBJECTIVE This systematic review reports rehabilitation characteristics reported after UCL injuries and compares reported outcomes based on early versus delayed rehabilitation. DATA SOURCES Our search utilized PubMed/MEDLINE, Embase, Web of Science, and Cochrane to identify all articles on UCL rehabilitation published between January 1, 2002 and October 1, 2022. STUDY SELECTION Studies in English with ≥5 patients that reported rehabilitation protocols for UCL injuries were evaluated. STUDY DESIGN Systematic review. LEVEL OF EVIDENCE Level 4. DATA EXTRACTION Data included sample characteristics, time to achieve physical therapy milestones, outcome scores, and return-to-play (RTP) rate and timing. RESULTS Our review included 105 articles with a total of 15,928 elbows (98% male; weighted mean age, 23 years; follow-up, 47 months), with 15,077 treated operatively and 851 treated nonoperatively. The weighted mean time patients spent adhering to nonweightbearing status was 42 days. The mean time until patients were given clearance for active range of motion (ROM) 15 days, full ROM 40 days, and elbow strengthening exercises 32 days. The mean time until all restrictions were lifted was 309 days. The mean time to begin a throwing program was 120 days. Across all rehabilitation characteristics, protocols for patients undergoing nonoperative management started patients on rehabilitation earlier. After UCL reconstruction, earlier active ROM (≤14 days), elbow strengthening (≤30 days), no restrictions (≤180 days), and throwing (≤120 days) postoperatively led to earlier RTP without a negative effect on functional outcome scores. CONCLUSION Current literature provides a spectrum of protocols for elbow UCL rehabilitation, regardless of management. Nonoperative patients began ROM activities, strengthening, and throwing programs sooner than operative patients, and earlier milestones led to earlier RTP.

Abstract
Background Although the ulnar collateral ligament reconstruction procedure has been increasing in popularity annually owing to its stable postoperative outcomes, the number of revision surgeries following ulnar collateral ligament reconstruction has increased. The success of the initial reconstruction surgery and further improvement in the return-to-play rates of the initial surgery are crucial. In this study, we report on ulnar collateral ligament reconstruction using the twisting technique, which aims to enhance the strength of the graft (palmaris longus tendon) to improve return-to-play rates. Methods We investigated the return-to-play rate and period in 60 cases (2016-2021) that underwent ulnar collateral ligament reconstruction using the twisting technique and 211 cases (2007-2019) that did not use the twisting technique. The twisting technique involved inserting the graft through the bone tunnel and then twisting the doubled tendon. Results According to the Conway-Jobe scale, the twisting technique group had 98.3% excellent, 1.7% good, 0% fair, and 0% poor results, with a mean return-to-play period of 9.8 months. The non-twisting technique group had 86.7% excellent, 9.0% good, 1.9% fair, and 2.4% poor results, with a mean return-to-play period of 11.4 months. The two groups showed significant differences in return-to-play rate (P = .020) and period (P = .022). Conclusion The clinical results of the twisting technique showed that the return-to-play rate of the twisting technique group was higher after than before the procedure, and the return-to-play period was shortened by more than 1 month. The twisting technique may improve the results of ulnar collateral ligament reconstruction surgery.

Low Rates of Postoperative Complications and Revision Surgery After Primary Medial Elbow Ulnar Collateral Ligament Repair. Arthrosc Sports Med Rehabil 2024; 6:100828. [PMID: 38313860 PMCID: PMC10835117 DOI: 10.1016/j.asmr.2023.100828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 11/02/2023] [Indexed: 02/06/2024] Open
Abstract
Purpose To evaluate the incidence of early postoperative complications and revision surgery in patients who underwent primary medial ulnar collateral ligament (MUCL) repair with minimum of 2-year follow-up. Methods A retrospective review of a national insurance database was conducted to identify patients with MUCL injuries who underwent primary MUCL repair between 2015 to 2020 with minimum 2-year follow-up. Patients >40 years of age and those who had concomitant elbow fractures or dislocations, lateral UCL injures, medial epicondylitis, elbow arthritis, or a history of previous elbow injury/surgery were excluded. The number of patients who underwent a concomitant ulnar nerve procedure (transposition or decompression) during the primary MUCL repair was recorded. Complications within 90 days of surgery and the incidence and timing of subsequent ipsilateral ulnar nerve surgery or revision MUCL surgery were assessed. Results A total of 313 patients (63.6% male) were included. The mean age was 20.3 ± 6.9 years, and mean follow-up was 3.7 ± 1.3 years. Concomitant ulnar nerve transposition or decompression was performed in 34.2% (N = 107). The early postoperative complication rate was 7.3% (N = 23). The most common complication was ulnar neuropathy (5.8%, N = 18). Wound complications, elbow stiffness, and medial epicondyle fractures were much less common (N = 5). Sixteen of 18 (88.9%) patients with postoperative ulnar neuropathy underwent transposition or decompression at the time of primary repair. Of these 18 patients, 5 (27.8%) underwent a subsequent ulnar nerve surgery (1 primary and 4 secondary), with the majority occurring within 6 months. The incidence of revision MUCL surgery was low (1.0%, N=3), with all 3 patients undergoing MUCL reconstruction. Conclusion There was a low incidence of early postoperative complications (7.3%) and 2-year revision MUCL surgery (1.0%) in young patients who underwent primary MUCL repair with no additional ligamentous, fracture, and dislocation-related diagnoses. All 3 (1.0%) MUCL revisions underwent reconstruction. Level of Evidence Level IV, therapeutic case series.

Abstract
While the term "athlete development" has been used to capture the changes (physical, psychological, etc.) that occur as an athlete moves from initial sport engagement to elite performance, much of the research in this area has focused on earlier stages of the pathway, with very little work examining the highest levels of sport. Considering a person's bio-psycho-social development continues through adulthood, the limited attention to development for athletes at higher competitive levels is perhaps surprising. In this short article, we highlight several notable discrepancies between different competitive levels (e.g., pre-professional sport and professional sport) in the way development is conceptualized, contextualized, and operationalized. We use available evidence to provide guidance for researchers and practitioners to encourage the delivery of structured developmental programming in professional sport systems to aid with the transitionary period between pre-elite and elite levels, and to help foster career longevity.

Upper-Extremity Injuries Have the Poorest Return to Play and Most Time Lost in Professional Baseball: A Systematic Review of Injuries in Major League Baseball. Arthroscopy 2022:S0749-8063(22)00863-5. [PMID: 36587750 DOI: 10.1016/j.arthro.2022.12.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 12/02/2022] [Accepted: 12/13/2022] [Indexed: 12/31/2022]
Abstract
PURPOSE To summarize the incidence of injuries occurring in professional baseball and compare player outcomes reported in the literature. METHODS We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across 3 databases (PubMed, MEDLINE, Embase). Inclusion criteria were studies of injury incidences and/or injury outcomes on active Major League Baseball (MLB) athletes and studies published in the English language. Exclusion criteria were non-MLB players, case series and case report studies with a cohort of ≤3 players, and/or review articles. RESULTS A total of 477 articles were identified from the initial search of 3 databases, with 105 studies meeting inclusion criteria. Among these articles, the most common injuries studied were elbow (38%), shoulder (14%), hip/groin (11%), hand/wrist (7%), head/face (7%), knee (7%), spine (5%), and foot/ankle (3%). Injuries with the greatest incidence included hand/wrist (150.3 per year), hamstring (7.8-73.5 per year), ulnar collateral ligament (UCL) tears (0.23-26.8 per year), gastrocnemius strains (24.2 per year), and concussions (3.6-20.5 per year). Lowest rates of return to play were seen following shoulder labral tears (40%-72.5%), rotator cuff tears (33.3%-87%), and UCL tears (51%-87.9%). The injuries leading to most time away from sport included elbow UCL tears (average 90.3 days treated nonoperatively to 622.8 days following revision reconstruction), shoulder labral tears (average 315-492 days), and anterior cruciate ligament (ACL) tears (average 156.2-417.5 days). Following ACL tears, rotator cuff tears, shoulder labral tears, and hip femoroacetabular impingement requiring arthroscopy, athletes had a significantly lower workloads compared with before injury upon return to play. CONCLUSIONS Most published investigations focus on elbow injuries of the UCL, with variable return to play and mixed performance following surgery. UCL tears, shoulder labral tears, and ACL tears result in the most missed time. Upper-extremity injury such as shoulder labral tears, rotator cuff tears, and UCL tears had the poorest return to play rates. Workload was most affected following ACL reconstruction, rotator cuff repair, shoulder labral repair, and hip arthroscopy for femoroacetabular impingement. LEVEL OF EVIDENCE IV, systematic review of level II-IV studies.

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
BACKGROUND Mixed Martial Arts (MMA) is an increasingly popular combat sport incorporating striking and grappling that results in a high incidence of injuries. OBJECTIVES The purpose of this study was to analyze the impact of injuries on the return to sport and post-injury performance of professional MMA athletes. We hypothesize that increased age is associated with lower probability of return to sport and diminished post-injury performance. METHODS Publicly available data (obtained from ESPN.com/MMA, UFC.com, Rotowire.com/MMA) from professional MMA fighters who resigned from fight cards due to injury from 2012 to 2014 were analyzed. Injury history, match history and outcomes, and duration of time to return to professional fighting were recorded and compared to a cohort consisting of uninjured opponents. RESULTS 454 fighters were included in the analysis. The mean age at the time of injury was 30.0±3.9 years. 94.4% of injured athletes were able to return to professional MMA, and athletes required a mean duration of 6.8±6.7 months between injury and their next professional fight (range 0.3-58 months). There was no significant difference in winning percentage in the post-injury period between the injured group and the uninjured group (p = 0.691). Increased age at the time of injury was associated with the odds of being able to return to professional fighting after injury (OR = 0.822, p = 0.001). CONCLUSION In this analysis of publicly available injury data on MMA fighters, there was a high rate of return to professional sport and no evidence of an associated decline in performance following major injury requiring withdrawal from a fight card. Older age at the time of injury was associated with decreased odds of being able to return to professional fighting. With increasing popularity of combat sports, sport-specific prognostic information will help guide and treat specific injuries associated with MMA participation.

Abstract
BACKGROUND Ulnar collateral ligament (UCL) reconstruction (UCLR) is a viable treatment option for patients with UCL insufficiency, especially in the overhead throwing athlete. Within the clinical literature, there is still no universally agreed upon optimal rehabilitation protocol and timing for return to sport (RTS) after UCLR. HYPOTHESIS There will be significant heterogeneity with respect to RTS criteria after UCLR. Most surgeons will utilize time-based criteria rather than functional or performance-based criteria for RTS after UCLR. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS All level 1 to 4 studies that evaluated UCLR with a minimum 1-year follow-up were eligible for inclusion. Studies lacking explicit RTS criteria, studies that treated UCL injury nonoperatively or by UCL repair, or studies reporting revision UCLR were excluded. Each study was analyzed for methodologic quality, RTS, timeline of RTS, and RTS rate. RESULTS Overall, 1346 studies were identified, 33 of which met the inclusion criteria. These included 3480 athletes across 21 different sports. All studies reported RTS rates either as overall rates or via the Conway-Jobe scale. Timelines for RTS ranged from 6.5 to 16 months. Early bracing with progressive range of motion (ROM) (93.9%), strengthening (84.8%), and participation in an interval throwing program (81.8%) were the most common parameters emphasized in these rehabilitation protocols. While all studies included at least 1 of 3 metrics for the RTS value assessment, most commonly postoperative rehabilitation (96.97%) and set timing after surgery (96.97%), no article completely defined RTS criteria after UCLR. CONCLUSION Overall, 93.9% of studies report utilizing bracing with progressive ROM, 84.8% reported strengthening, and 81.8% reported participation in an interval throwing program as rehabilitation parameters after UCLR. In addition, 96.97% reported timing after surgery as a criterion for RTS; however, there is a wide variability within the literature on the recommended time from surgery to return to activity. Future research should focus on developing a comprehensive checklist of functional and performance-based criteria for safe RTS after UCLR.

Abstract
Background While the incidence of ulnar collateral ligament reconstruction (UCLR) has increased across all levels of play, few studies have investigated the long-term outcomes in nonprofessional athletes. Purpose To determine the rate of progression to higher levels of play, long-term patient-reported outcomes (PROs), and long-term patient satisfaction in nonprofessional baseball players after UCLR. Study Design Case series; Level of evidence, 4. Methods We evaluated UCLR patients who were nonprofessional baseball athletes aged <25 years at a minimum of 5 years postoperatively. Patients were assessed with the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score (KJOC), the Timmerman-Andrews (T-A) Elbow score, the Mayo Elbow Performance Score (MEPS), and a custom return-to-play questionnaire. Results A total of 91 baseball players met the inclusion criteria, and 67 (74%) patients were available to complete the follow-up surveys at a mean follow-up of 8.9 years (range, 5.5-13.9 years). At the time of the surgery, the mean age was 18.9 ± 1.9 years (range, 15-24 years). Return to play at any level was achieved in 57 (85%) players at a mean time of 12.6 months. Twenty-two (32.8%) of the initial cohort returned to play at the professional level. Also, 43 (79.1%) patients who initially returned to play after surgery reported not playing baseball at the final follow-up; of those patients, 12 reported their elbow as the main reason for eventual retirement. The overall KJOC, MEPS, and T-A scores were 82.8 ± 18.5 (range, 36-100), 96.7 ± 6.7 (range, 75-100), and 91.9 ± 11.4 (range, 50-100), respectively . There was an overall satisfaction score of 90.6 ± 21.5 out of 100, and 64 (95.5%) patients reported that they would undergo UCLR again. Conclusion In nonprofessional baseball players after UCLR, there was a high rate of progression to higher levels of play. Long-term PRO scores and patient satisfaction were high. The large majority of patients who underwent UCLR would undergo surgery again at long-term follow-up, regardless of career advancement.

Abstract
Background: There is a lack of consensus to guide patient return to sport (RTS) after elbow ulnar collateral ligament surgery (eUCLS). Purpose: To describe the reported RTS criteria after eUCLS in the athletic population. Study Design: Scoping review; Level of evidence, 4. Methods: This scoping review was performed by adhering to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses–Scoping Review) guidelines. We searched 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced) and the gray literature for English-language studies that reported at least 1 RTS criterion in athletes after eUCLS. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation. Results: Included were 14 studies and 1335 athletes with a mean age of 21.4 ± 1.1 years. Time from surgery (range, 6-16 months) was the most common RTS criterion used, and it was reported by all 14 of the included articles. RTS criteria reported less often were pain (3/14; 21%), successful completion of a throwing program (3/14; 21%), muscle strength of the forearm muscles (1/14; 7%), and “normal” range of motion and muscle strength of the elbow and shoulder joints on the operated upper extremity (1/14; 7%). All studies used 1 to 5 of the above RTS criteria. Conclusion: Only 14 studies reported 1 or more RTS criteria after eUCLS in athletes, and time was the most common RTS criterion used. Our results highlight the need for a coordinated effort among surgeons, physical therapists, and athletic trainers in order to establish evidence-based RTS criteria after eUCLS in athletes so athletes can safely to sport and prolong their athletic careers.

[PMID: 34377709 PMCID: PMC8320574 DOI: 10.1177/23259671211009589] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 01/05/2021] [Indexed: 11/29/2022] Open
Abstract
Background: Return to sport (RTS) commonly serves as a measure for assessment of clinical outcomes in orthopaedic sports medicine surgery. Unfortunately, while RTS is commonly utilized in research for this purpose, currently there is no widely accepted or standardized definition for when an athlete has officially returned to his or her sport. Purpose: To conduct a systematic review to evaluate and report the differences in specific definitions of RTS utilized in the orthopaedic surgery literature. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed using PubMed, EMBASE, and Cochrane Trials databases per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Search terms consisted of variations of “RTS” combined with variations of “orthopedic surgery” and “define” to capture as many relevant articles as possible. The definition of RTS was recorded and analyzed. Results: A total of 718 articles were identified in the initial search, 29 of which met eligibility criteria, providing a clear definition of RTS. Of the 29 studies included, 20 (69.0%) defined RTS as an athlete competing in a game or other competitive play. Three (10.3%) defined this as the athlete competing in a game or other competitive play but with an explicitly stated competition-level modifier of the athlete returning to his or her preinjury level of competition. Two articles (6.9%) included returning to training or practice, and the remaining 4 articles (13.8%) used terminology other than the standard RTS. Conclusion: There is variability in the definition of RTS used in orthopaedic sports medicine literature. Most studies refer to the athlete competing in a game or other competitive play. Other variants include returning to practice/training and explicitly defined competition levels and objectives. Future studies should aim to standardize the definition of RTS to facilitate more precise assessment of outcome after sports medicine surgery. Using terminology that describes components of the recovery and rehabilitation process, such as “return to participation” and “return to performance,” in addition to RTS will allow us to more clearly understand the athlete’s recovery and associated level of competition or performance.

Abstract
Background: The Major League Baseball (MLB) All-Star Game (ASG) Home Run Derby (HRD) remains a highly anticipated event, during which contestants can take hundreds of maximum-effort swings en route to hitting a multitude of home runs. Critics have openly questioned the risk-benefit of HRD participation as it pertains to injury, alterations in swing mechanics, and timing. Purpose: To determine whether participation in the MLB ASG HRD was associated with both increased injury risk and decline in second-half performance in MLB players. Study Design: Cohort study; Level of evidence, 3. Methods: MLB players who participated in the HRD between 2006 and 2019 were identified through publicly available internet databases. A control group of ASG participants who had the highest home run totals in the first half of the corresponding MLB season were selected as a control group. Multivariable linear regression was used to determine independent associations between HRD participation and batting metrics in the second half of the season. Multivariable logistic regression also assessed the impact of HRD participation on injured list placement during the second half of the concurrent MLB season. Results: A total of 114 HRD participants and 114 ASG participant controls competed during the study period. No statistically significant differences were seen in batting metrics in the second half of the MLB season between HRD participants and ASG controls, although HRD participants had a significantly lower wins-above-replacement statistic for the season compared with controls (4.69 ± 2.06 vs 5.33 ± 2.08; P = .021). HRD participation was not significantly associated with injury during the second half. The number of HRD rounds in which a player participated did not result in a statistically significant increased odds of injury during the second half of the MLB season. Conclusion: HRD participants did not have increased odds of being placed on the injured list during the second half of the MLB season compared with controls, nor did they experience second-half performance declines in offensive production versus controls when multivariable linear regression analysis was performed.

Abstract
Wearable sensors enable the real-time and non-invasive monitoring of biomechanical, physiological, or biochemical parameters pertinent to the performance of athletes. Sports medicine researchers compile datasets involving a multitude of parameters that can often be time consuming to analyze in order to create value in an expeditious and accurate manner. Machine learning and artificial intelligence models may aid in the clinical decision-making process for sports scientists, team physicians, and athletic trainers in translating the data acquired from wearable sensors to accurately and efficiently make decisions regarding the health, safety, and performance of athletes. This narrative review discusses the application of commercial sensors utilized by sports teams today and the emergence of descriptive analytics to monitor the internal and external workload, hydration status, sleep, cardiovascular health, and return-to-sport status of athletes. This review is written for those who are interested in the application of wearable sensor data and data science to enhance performance and reduce injury burden in athletes of all ages.

Return-to-Play and Competitive Outcomes After Ulnar Collateral Ligament Reconstruction Among Baseball Players: A Systematic Review. Orthop J Sports Med 2020; 8:2325967120966310. [PMID: 33748295 PMCID: PMC7905078 DOI: 10.1177/2325967120966310] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Background: Ulnar collateral ligament (UCL) reconstruction (UCLR) is very common in baseball. However, no review has compared the return-to-play (RTP) and in-game performance statistics of pitchers after primary and revision UCLR as well as of position players after UCLR. Purpose: To review, synthesize, and evaluate the published literature on outcomes after UCLR in baseball players to determine RTP and competitive outcomes among various populations of baseball players. Study Design: Systematic review; Level of evidence, 4. Methods: A literature search including studies between 1980 and November 4, 2019, was conducted for articles that included the following terms: ulnar collateral ligament, elbow, medial collateral ligament, Tommy John surgery, throwing athletes, baseball pitchers, biomechanics, and performance. To be included, studies must have evaluated baseball players at any level who underwent UCLR (primary or revision) and assessed RTP and/or competitive outcomes. Results: A total of 29 studies with relatively high methodological quality met the inclusion criteria. After primary UCLR, Major League Baseball (MLB) pitchers returned to play in 80% to 97% of cases in approximately 12 months; however, return to the same level of play (RTSP) was less frequent and took longer, with 67% to 87% of MLB pitchers returning in about 15 months. RTP rates for MLB pitchers after revision UCLR were slightly lower, ranging from 77% to 85%, while RTSP rates ranged from 55% to 78%. RTP rates for catchers (59%-80%) were generally lower than RTP rates for infielders (76%) and outfielders (89%). All studies found a decrease in pitching workloads after UCLR. Fastball usage may also decrease after UCLR. Changes in earned run average and walks plus hits per inning pitched were inconclusive. Conclusion: Pitchers returned to play after UCLR in approximately 12 months and generally took longer to return to their same level of play. Pitchers also returned to play less frequently after revision UCLR. After both primary and revision UCLR, professional pitchers experienced decreased workloads and potentially decreased fastball usage as well. Catchers may RTP after UCLR less frequently than pitchers, infielders, and outfielders possibly because of the frequency of throwing in the position. These results will help guide clinical decision making and patient education when treating UCL tears in baseball players.

Abstract
Background: The increase in ulnar collateral ligament (UCL) elbow reconstructions over the past 20 years has affected younger athletes more than any other age group. Although return to play and postoperative performance have been extensively studied in professional baseball players, outcomes in collegiate baseball players are less known. Purpose/Hypothesis: The purpose of this study was to characterize return to play and changes in performance after UCL reconstruction (UCLR) in collegiate baseball players. We hypothesized that collegiate baseball players would have similar return-to-play rates compared with professional athletes and no significant differences in performance compared with matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: Collegiate athletes undergoing UCLR by a single surgeon were identified. Postoperatively, individual collegiate career paths were analyzed through use of publicly available data from team websites, injury reports, and press releases. Data obtained included time to return to competition, number of collegiate seasons played after surgery, total games started and played, seasonal wins, losses, saves, innings played, hits, earned run average (ERA), home runs, shutouts, strikeouts, walks, and walks plus hit per inning pitched (WHIP). The UCLR group was compared with a matched control group of collegiate pitchers without elbow injury. Results: Of the 58 collegiate baseball players analyzed (mean ± SD age, 19.95 ± 1.19 years), 84.5% returned to play at the collegiate level. Players returned to competition at 16.98 ± 6.16 months postoperatively and competed for 1.60 ± 0.84 seasons postoperatively. In terms of career longevity, 81.0% of collegiate pitchers either completed their collegiate eligibility or remained on active rosters, and 2 players (4.1%) ultimately played at the professional level after UCLR. Compared with a matched cohort, the UCLR group had no significant differences in collegiate pitching performance statistics after surgery. Conclusion: College baseball players returned to play at a rate comparable with the rate published in prior literature on professional pitchers and often completed their collegiate playing eligibility postoperatively. Compared with controls, the UCLR group had no statistically significant differences in pitching performance postoperatively. Further studies are needed to determine the exact reasons why college players retire despite having endured extensive surgical and postoperative rehabilitation processes related to UCLR. Younger populations are experiencing elbow injuries at an increasing rate secondary to increased workloads at the amateur level. As these athletes matriculate into the collegiate ranks, they are at continued risk of sustaining UCL injury, and little explicit information is available on their prospects of return to play and career longevity after UCLR.

Abstract
BACKGROUND Recent studies evaluating nonoperative treatment of elbow ulnar collateral ligament (UCL) injuries augmented with platelet-rich plasma (PRP) have shown promising results. To date, no comparative studies have been performed on professional baseball players who have undergone nonoperative treatment with or without PRP injections for UCL injuries. HYPOTHESIS Players who received PRP injections would have better outcomes than those who did not receive PRP. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS The Major League Baseball (MLB) Health and Injury Tracking System identified 544 professional baseball players who were treated nonoperatively for elbow UCL injuries between 2011 and 2015. Of these, 133 received PRP injections (PRP group) before starting their nonoperative treatment program, and 411 did not (no-PRP group). Player outcomes and a Kaplan-Meier survival analysis were compared between groups. In addition, to reduce selection bias, a 1:1 matched comparison of the PRP group versus the no-PRP group was performed. Players were matched by age, position, throwing side, and league status: major (MLB) and minor (Minor League Baseball [MiLB]). A single radiologist with extensive experience in magnetic resonance imaging (MRI) interpretation of elbow injuries in elite athletes analyzed 243 MRI scans for which images were accessible for tear location and grade interpretation. RESULTS Nonoperative treatment of UCL injuries resulted in an overall 54% rate of return to play (RTP). Players who received PRP had a significantly longer delay in return to throwing (P < .001) and RTP (P = .012). The matched cohort analysis showed that MLB and MiLB pitchers in the no-PRP group had a significantly faster return to throwing (P < .05) and the MiLB pitchers in the no-PRP group had a significantly faster RTP (P = .045). The survival analysis did not reveal significant differences between groups over time. The use of PRP, MRI grade, and tear location were not statistically significant predictors for RTP or progression to surgery. CONCLUSION In this retrospective matched comparison of MLB and MiLB pitchers and position players treated nonoperatively for a UCL tear, PRP did not improve RTP outcomes or ligament survivorship, although there was variability with respect to PRP preparations, injection protocols, time from injury to injection, and rehabilitation programs. MRI grade and tear location also did not significantly affect RTP outcomes or progression to surgery.

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 Injury to the ulnar collateral ligament of the elbow is relatively common among baseball pitchers. Ulnar collateral ligament reconstruction (UCLR) has revolutionized the management of this injury, allowing a greater proportion of pitchers to return to play. PURPOSE To assess the return to play and in-game performance specific to baseball pitchers who have undergone primary UCLR. STUDY DESIGN Systematic review. METHODS This review was conducted according to the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The electronic databases MEDLINE, EMBASE, and PubMed were searched for relevant studies, and pertinent data were abstracted. Only studies reporting in-game performance statistics (earned run average [ERA], pitching velocity, innings pitched per season, etc) of pitchers after UCLR were included. The methodological index for nonrandomized studies (MINORS) was used to assess study quality. RESULTS A total of 14 studies and 1520 pitchers were included in this systematic review. All studies were of level 3 or 4 evidence, and the mean ± SD MINORS score was 14.4 ± 3.0, which indicates fair quality of evidence for nonrandomized studies. The rates of return to any level of pitching after UCLR ranged from 79% to 100%. Subgroup analysis revealed that 79% to 87% of Major League Baseball (MLB) pitchers returned to preinjury levels of pitching. The mean time to return to play was 19.8 ± 13.5 months, and the mean time to return to competition for MLB pitchers was 17.3 ± 2.4 months. Of the 5 studies reporting ERA, 2 cited a significant increase after UCLR, and 1 indicated a significant decrease. Of the 4 studies reporting fastball velocity, 3 cited decreased pitching velocities after UCLR. All studies found that pitchers pitched, on average, fewer innings per game or season after UCLR. CONCLUSION There was a high rate of return to pitching after UCLR. However, most studies showed that UCLR was associated with a prolonged recovery and significant decline in pitching performance as objectively measured by in-game statistics. The strength of these conclusions is limited by the quality of the available literature and inconsistencies in the reporting of outcomes.

Abstract
BACKGROUND A recently introduced classification of medial ulnar collateral ligament (UCL) tears has demonstrated high interobserver and intraobserver reliability, but little is known about its prognostic utility. The purpose of this study was to assess the relationship of the magnetic resonance imaging (MRI)-based classification system and nonoperative vs. operative management. Secondary objectives included subanalysis of baseball players. METHODS Eighty-five consecutive patients with UCL tears after a standardized treatment paradigm were categorized as operative vs. nonoperative. UCL tears of patients with a minimum of 1-year follow-up were retrospectively classified using the MRI-based classification system. Subanalyses for baseball players included return-to-play and return-to-prior performance. RESULTS A total of 80 patients (62 baseball players, 54 pitchers) met inclusion criteria. A total of 51 patients underwent surgery, and 29 patients completed nonoperative management. In baseball players, 59% of the proximal tears were treated nonoperatively and 97% of the distal tears were treated operatively; 100% of the proximal partial-thickness tears and 100% of the distal complete tears were treated nonoperatively and operatively, respectively. Patients with distal (odds ratio: 48.4, P < .0001) and complete (odds ratio: 5.0, P = .004) tears were more likely to undergo surgery. Baseball players, regardless of position, were determinants of operative management, and there was no difference in return-to-play clearance and return-to-prior performance between the operative and nonoperative groups. CONCLUSION A reliable 6-stage MRI-based classification addressing UCL tear grade and location may confer decision making between operative and nonoperative management. Complete and distal tears carry a markedly increased risk of failing nonoperative care compared with proximal, partial tears.

Abstract
Background A recently introduced classification system of medial ulnar collateral ligament (UCL) tears accounting for location and severity has demonstrated high interobserver and intraobserver reliability, but little is known about its clinical utility. Purpose The primary purpose of this study was to assess the relationship of the magnetic resonance imaging (MRI)-based classification system in predicting which athletes had success with nonoperative versus operative treatment after completing a standardized rehabilitation program. A secondary objective included return to play (RTP) and return to prior performance (RPP) analyses of baseball players. Study Design Cohort study; Level of evidence, 3. Methods After an a priori power analysis, 58 consecutive patients with UCL tears and a minimum of 2-year follow-up were retrospectively divided into 2 groups: those who successfully completed operative treatment and those who completed nonoperative treatment. The MRI-based classification stages accounting for UCL tear location and severity were compared between the nonoperative and operative groups. A subanalysis for baseball players, including RTP and RPP, was performed. Results A total of 58 patients (40 baseball players [34 pitchers]) met inclusion criteria. Of these patients 35 (32 baseball players [27 pitchers]) underwent surgery, and 23 (8 baseball players [7 pitchers]) underwent nonoperative management. No patients in the nonoperative arm crossed over to surgery after completing the rehabilitation program. Patients with distal tears (odds ratio, 48.0; P = .0004) and complete tears (odds ratio, 5.4; P = .004) were more likely to undergo surgery. Baseball players, regardless of position, were confounding determinants of operative management, although there was no difference in RTP and RPP between treatment arms. Conclusion A 6-stage MRI-based classification system addressing UCL tear location and severity may help early decision making, as patients likely to fail nonoperative treatment have complete, distal tears, whereas those with proximal, partial tears may be more amenable to nonoperative management.

Abstract
Background Femoroacetabular impingement (FAI) is a common cause of hip pain that may lead to decreased performance in Major League Baseball (MLB) players. Purpose To determine the (1) return-to-sport (RTS) rate in MLB players after hip arthroscopic surgery for FAI; (2) postoperative career length, innings pitched (IP) (pitchers), and plate appearances (PA) (position players); (3) preoperative 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 MLB athletes who underwent hip arthroscopic surgery for FAI and matched controls were identified. Demographic and performance data were collected. RTS was defined as playing in at least 1 MLB game after surgery. Continuous variables of each group were compared using a 2-tailed paired-samples Student t test for normally distributed data. The chi-square test was used to analyze categorical data. The Bonferroni correction was used to control for multiple comparisons, with statistical significance defined by a P value of ≤.007. Results A total of 50 players (57 surgeries) were analyzed (mean age, 30.4 ± 3.9 years; mean MLB experience at the time of surgery, 7.0 ± 4.6 years). Pitchers (31 surgeries; 54.4%) represented the largest proportion of players analyzed. Of these players, 42 (47 surgeries; 82.5%) were able to RTS at a mean of 8.3 ± 4.1 months. The overall 1-year MLB career survival rate of players undergoing FAI surgery was 78.9%. Players in the control group were in MLB a similar number of years (4.0 ± 2.9 years) to players who underwent surgery (3.3 ± 2.4 years) (P > .007). There was no significant decrease in IP or PA per season after surgery (P > .007). There was no significant difference in performance for pitchers and nonpitchers compared with matched controls after surgery (P > .007). Conclusion The RTS rate for MLB athletes after hip arthroscopic surgery for FAI was high. There were similar IP, PA, and career lengths postoperatively compared with preoperatively and with matched controls. There was no significant difference in performance for pitchers and nonpitchers compared with matched controls after surgery.

Abstract
BACKGROUND Ulnar collateral ligament (UCL) reconstruction (UCLR) has shown reliable rates of return to play, with conflicting results on pitching performance after players' return. PURPOSE To evaluate Major League Baseball (MLB) pitching performance before and after UCLR performed at a single institution. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS MLB pitchers (minor league players were excluded) who underwent UCLR at our institution between 2002 and 2016 were identified. Player information and return to play were determined including pitching level (MLB vs minor league) and total number of years played after surgery. Pitching performance statistics were evaluated for 3 years before surgery and for 3 years after returning to play including earned run average (ERA), walks plus hits per inning pitched (WHIP), innings pitched, wins above replacement, runs above replacement, and pitch velocity. RESULTS A total of 54 MLB pitchers were identified, with 46 primary and 8 revision reconstructions. The mean time to return to play was 13.8 months (primary reconstruction: 13.7 months). The majority returned to play with a 94% return rate (primary reconstruction: 96%), and 80% returned to MLB play (primary reconstruction: 82%). Three primary reconstructions required revision surgery. Pitchers played a mean of 3.2 years in MLB and 4.6 years total after surgery (39% still playing). Pitching workload and performance were maintained or improved after surgery. The preoperative ERA was 4.63 versus 4.13 after returning to play ( P = .268). Fastball velocity ( P = .032), ERA ( P = .003), and WHIP ( P = .001) worsened the first year after surgery and then improved the second year (ERA: 4.63 to 4.06 [ P = .380]; WHIP: 1.35 to 1.32 [ P = .221]; fastball velocity: 91.3 to 91.9 mph [ P = .097]). Compared with a matched control group, pitchers who had UCLR showed improvements or maintained performance after reconstruction including improved ERA ( P = .007), WHIP ( P = .025), and fastball velocity ( P = .006). CONCLUSION MLB players experienced a high rate of return to play and previous level of play after UCLR. Pitching workload was maintained after returning to play. Pitching performance initially decreased the first year after returning and then improved or reverted to previous levels after the first year from UCLR.
