Abstract
BACKGROUND Thoracic outlet syndrome (TOS) remains a rare diagnosis but is being recognized as a cause of upper extremity dysfunction in professional baseball players. PURPOSE/HYPOTHESIS The purpose was to determine performance and return-to-play (RTP) outcomes in professional baseball players after surgical treatment of TOS. The hypothesis was that there would be a high RTP rate in professional baseball players after TOS surgery with no statistical differences in performance between pitchers who had TOS surgery and matched controls. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All professional baseball players who underwent surgical treatment of TOS between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Demographic and performance data (before and after surgery) for each player were recorded. Performance variables were then compared between players who underwent TOS surgery and matched controls. The matching criteria were no history of previous surgeries on affected arm, age at time of surgery, throwing side, level of play (Major or Minor League Baseball), and years of experience playing professional baseball. RESULTS Overall, 52 players underwent surgery for TOS, of whom 46 (88%) were pitchers. The type of TOS was neurogenic in 69% and venous in 29%. One player had arterial TOS. After TOS surgery, 79% of players returned to play at the same or higher level (RTSP) by 9.5 months and played ≥3 years after surgery. No differences were found in RTSP rate based on the type of TOS. No statistical difference was found in RTP rates between major and minor league players. Pitchers had a 76% RTSP, which was similar to the natural attrition for control pitchers (P = .874). After TOS surgery, pitchers saw a decline in several performance metrics, but these declines were not different from those of control pitchers, indicating that the decline in performance after TOS surgery was no faster than is seen in healthy professional pitchers as they age. CONCLUSION The rate of RTSP after surgery for TOS in professional baseball players was 79%. There was no difference in RTP based on the type of TOS. Pitchers who underwent surgery for TOS had no significant differences in pitching performance metrics after surgery compared with matched controls.

Abstract
Hypothesis and/or Background The incidence of elbow medial ulnar collateral ligament (MUCL) injuries has been increasing, leading to advances in surgical treatments. However, it is not clear that there is consensus among surgeons regarding diagnostic imaging, the indications for acute surgery and postoperative rehabilitation. The purpose of this study is evaluate surgeon variability in the presurgical, surgical, and postsurgical treatment of MUCL injuries regarding the imaging modalities used for diagnosis, indications for acute surgical treatment, and postoperative treatment recommendations for rehabilitation and return to play (RTP). Our hypothesis is that indications for acute surgical treatment will be highly variable based on MUCL tear patterns and that agreement on the time to RTP will be consistent for throwing athletes and inconsistent for nonthrowing athletes. Methods A survey developed by 6 orthopedic surgeons with expertise in throwing athlete elbow injuries was distributed to 31 orthopedic surgeons who routinely treat MUCL injuries. The survey evaluated diagnostic and treatment topics related to MUCL injuries, and responses reaching 75% agreement were considered as high-level agreement. Results Twenty-four surgeons responded to the survey, resulting in a 77% response rate. There is 75% or better agreement among surveyed surgeons regarding acute surgical treatment for distal full thickness tears, ulnar nerve transposition in symptomatic patients or with ulnar nerve subluxation, postoperative splinting for 1-2 weeks with initiation of rehabilitation within 2 weeks, the use of bracing after surgery and the initiation of a throwing program at 3 months after MUCL repair with internal brace by surgeons performing 20 or more MUCL surgeries per year. There were a considerable number of survey topics without high-level agreement, particularly regarding the indications for acute surgical treatment, the time to return to throwing and time RTP in both throwing and nonthrowing athletes. Discussion and/or Conclusion The study reveals that there is agreement for the indication of acute surgical treatment of distal MUCL tears, duration of bracing after surgery, and the time to initiate physical therapy after surgery. There is not clear agreement on indications for surgical treatment for every MUCL tear pattern, RTP time for throwing, hitting and participation in nonthrowing sports.

Abstract
Failure rates among primary Anterior Cruciate Ligament Reconstruction (ACLR) range from 3.2% to 11.1%. Recently, there has been increased focus on surgical and anatomic considerations which predispose patients to failure, including excessive posterior tibial slope (PTS), unaddressed high-grade pivot shift, and improper tunnel placement. The purpose of this review was to provide a current summary and analysis of the literature regarding patient-related and technical factors surrounding revision ACLR, rehabilitation considerations, overall outcomes and return to sport (RTS) for patients who undergo revision ACLR. There is a convincingly higher re-tear and revision rate in patients who undergo ACLR with allograft than autograft, especially amongst the young, athletic population. Unrecognized Posterior Cruciate Ligament (PLC) injury is a common cause of ACLR failure and current literature suggests concurrent operative management of high-grade PLC injuries. Given the high rates of revision surgery in young active patients who return to pivoting sports, the authors recommend strong consideration of a combined ACLR + Anterolateral Ligament (ALL) or Lateral extra-articular tenodesis (LET) procedure in this population. Excessive PTS has been identified as an independent risk factor for ACL graft failure. Careful consideration of patient-specific factors such as age and activity level may influence the success of ACL reconstruction. Additional technical considerations including graft choice and fixation method, tunnel position, evaluation of concomitant posterolateral corner and high-grade pivot shift injuries, and the role of excessive posterior tibial slope may play a significant role in preventing failure.

Abstract
Purpose To examine the relationship between tibial tubercle-trochlear groove (TT-TG) distance and patellar tendon length. Methods All healthy athletes who underwent anterior cruciate ligament reconstruction who had a magnetic resonance imaging (MRI) study of the knee on file between July 2018 and June 2019 at a single institution were retrospectively reviewed. Exclusion criteria included patients without an MRI study of the knee on file or with an MRI of insufficient quality precluding reliable calculation of TT-TG and patellar tendon length. MRIs were reviewed to calculate TT-TG, patellar tendon length, and Caton-Deschamps Index (CDI). Patient charts were reviewed to obtain anthropometric characteristics including sex, concomitant injuries, and previous knee procedures as well as age at time of MRI. Spearman correlations were used to assess the relationship between TT-TG, patellar tendon length, and CDI, with regression analysis performed to assess for relationships between TT-TG, patellar tendon length, and patient-specific factors. Results Overall, 235 patients (99 female [42.1%], 136 male [57.9%]; mean age: 30.0 years [23.0; 40.0]) were included. Inter-rater reliability between the 2 reviewers was 0.888 for TT-TG, 0.804 for patellar tendon length, and 0.748 for CDI, indicating strong agreement. The correlation between TT-TG and patellar tendon length was 0.021, indicating no true relationship. The correlation between TT-TG and CDI was -0.048 and that of patellar tendon length and CDI was 0.411, indicating a weak positive relationship. Regression analysis found that male sex is strongly correlated with a longer patellar tendon length (odds ratio 2.65, 95% confidence interval 1.33-3.97, P < .001). Conclusions In this study, no correlation was found between TT-TG and patellar tendon length or CDI. Male sex was correlated with a longer patellar length. Level of Evidence Level III.

Abstract
Ulnar collateral ligament (UCL) tears in the elbow have been rising in recent years, most specifically in baseball players. Although many of these tears occur in professional (minor and major league) baseball pitchers, there has been a dramatic rise in UCL injuries in adolescents, at a rate of 9% per year. Although some UCL tears can be treated conservatively, those that fail conservative treatment often require surgical intervention to allow players to return to sport. Although UCL reconstruction has been the gold standard in surgical treatment for many years, UCL repair with suture augmentation has grown in popularity. Initial results of UCL repair with suture augmentation have been promising, and a recent review comparing UCL repair with suture augmentation from both a biomechanical and clinical outcome perspective confirms that UCL repair may be superior to reconstruction for patients with proximal or distal tears and good quality UCL tissue for repair.

Abstract
BACKGROUND Injuries to the medial ulnar collateral ligament (UCL) are common among baseball pitchers due to repetitive stress on the soft tissue stabilizers of the elbow during pitching. Dynamic stress ultrasound (SUS) can be used to evaluate the UCL and ulnohumeral joint to identify anatomic risk factors of those who will require UCL reconstruction (UCLR). PURPOSE To determine whether any adaptive or morphological changes detectable on SUS can predict injury to the UCL in professional baseball pitchers. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 203 professional baseball pitchers who underwent SUS at preseason training sessions over the course of 18 years were categorized into 1 of 2 groups: those without a history of shoulder, arm, elbow, or forearm surgery or injuries (healthy cohort; n = 184) and those who underwent UCLR the same season as SUS (UCLR cohort; n = 19). Ligament thickness, joint spacing, and laxity were compared. An additional matched cohort analysis was conducted using 10 players from each group to detect differences in the progression of UCL and ulnohumeral joint measures in the year before injury. RESULTS The UCLR cohort, when compared with the healthy cohort, had higher relative (ie, nondominant-side measurements subtracted from dominant-side measurements) resting ulnohumeral joint space (median, 0.50 vs 0.20 mm, respectively; P = .006) and higher rates of hypoechoic foci (57.9% vs 30.4%, respectively; P = .030). Players of both groups had similar dominant UCL thickness (P = .161), ulnohumeral joint space at rest (P = .321), space under stress (P = .498), and laxity (P = .796). Groups did not differ in terms of relative UCL thickness, ulnohumeral joint space under stress, or relative laxity. In the year before UCL injury, the UCLR cohort, compared with the matched healthy cohort, had a greater increase in mean dominant UCL thickness (0.94 vs -0.60 mm, respectively; P = .038) and a greater increase in relative median UCL thickness (1.35 vs -0.35 mm, respectively; P = .045). Players in the healthy cohort were statistically older than those in the UCLR cohort (23 vs 22 years, respectively; P = .004). No differences in ulnohumeral stress spacing or laxity were detected. CONCLUSION SUS of players who underwent UCLR demonstrated a progressive increase in UCL thickness over 1 year, higher rates of hypoechoic foci, and increased ulnohumeral rest space compared with SUS of uninjured players.

Abstract
BACKGROUND There is a paucity of data analyzing dynamic stress ultrasound (SUS) findings in elite pitchers who have undergone ulnar collateral ligament (UCL) reconstruction (UCLR) and returned to sport. PURPOSE To identify longitudinal, perioperative changes in the elbows of professional baseball pitchers who have undergone UCLR and to compare these findings with a matched cohort of healthy pitchers. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS This study used prospectively collected data from dynamic elbow SUS analyses of professional baseball pitchers within a single Major League Baseball organization. Pitchers were divided into 2 cohorts: a UCLR cohort and healthy cohort. The UCLR cohort eligibility included availability of (1) SUS from preseason of injury/UCLR and (2) SUS from ≥2 years after surgery. These players were 1:1 matched to players with no history of upper extremity injury to form the healthy cohort. Ligament thickness and ulnohumeral joint space at rest and under stress were directly measured. Joint laxity was calculated by subtracting joint space at rest from joint space under stress. The term "relative" was used to describe calculated differences where nondominant measurements were subtracted from dominant-side measurements. RESULTS Eight pitchers were included in the UCLR group and matched to 8 healthy pitchers (mean age at initial SUS examination, 19.6 years). At a minimum follow-up of 2 years, there were no significant differences between groups in terms of relative or dominant arm rest space, stress space, or laxity. Longitudinally (final measurements - baseline measurements), the mean relative ulnohumeral rest space decreased in the UCLR group and increased in the healthy group (-0.36 mm vs +0.50 mm; P = .032). The finding of increased UCL thickness in the UCLR group was expected, as UCL grafts are typically thicker than native ligaments. CONCLUSION Ulnhohumeral joint stability was achieved after UCLR as indicated by similar rest space, stress space, and joint laxity in dominant arms compared with a matched healthy cohort. A significant decrease in relative rest space after UCLR may represent the achievement of stability in surgery patients. Alternatively, the increase in ulnohumeral rest space seen in the healthy cohort may represent adaptive changes from pitching at a professional level.

Abstract
We evaluated the impact of training set size on generative adversarial networks (GANs) to synthesize brain MRI sequences. We compared three sets of GANs trained to generate pre-contrast T1 (gT1) from post-contrast T1 and FLAIR (gFLAIR) from T2. The baseline models were trained on 135 cases; for this study, we used the same model architecture but a larger cohort of 1251 cases and two stopping rules, an early checkpoint (early models) and one after 50 epochs (late models). We tested all models on an independent dataset of 485 newly diagnosed gliomas. We compared the generated MRIs with the original ones using the structural similarity index (SSI) and mean squared error (MSE). We simulated scenarios where either the original T1, FLAIR, or both were missing and used their synthesized version as inputs for a segmentation model with the original post-contrast T1 and T2. We compared the segmentations using the dice similarity coefficient (DSC) for the contrast-enhancing area, non-enhancing area, and the whole lesion. For the baseline, early, and late models on the test set, for the gT1, median SSI was .957, .918, and .947; median MSE was .006, .014, and .008. For the gFLAIR, median SSI was .924, .908, and .915; median MSE was .016, .016, and .019. The range DSC was .625-.955, .420-.952, and .610-.954. Overall, GANs trained on a relatively small cohort performed similarly to those trained on a cohort ten times larger, making them a viable option for rare diseases or institutions with limited resources.

Abstract
BACKGROUND AND HYPOTHESIS A double cortical button technique for ulnar collateral ligament reconstruction (UCLR) has advantages including significant control over graft tensioning, less concern about graft length, and minimized risk of bone tunnel fracture compared with traditional UCLR techniques. This double cortical button technique was recently found to be noninferior in mechanical performance to the traditional docking technique regarding joint strength, joint stiffness, and graft strain. However, clinical outcomes have not been compared between these UCLR techniques. Therefore, the purpose of this study was to determine whether baseball players who underwent UCLR with a double cortical button (double button) technique have similar return-to-sport (RTS) outcomes to baseball players who underwent UCLR with the traditional docking (docking) technique. MATERIALS AND METHODS Baseball players who underwent primary UCLR from 2011 to 2020 across 2 institutions were identified. Included patients were contacted to complete a follow-up survey evaluating reoperations, RTS, and functional outcome scores. Functional outcome surveys include the Kerlan-Jobe Orthopaedic Clinic score, the Conway-Jobe score, the Andrews-Timmerman elbow score, and the Single Assessment Numeric Evaluation score. RESULTS Overall, 78 male baseball players (age: 18.9 ± 2.4 years) with an average follow-up of 3.1 ± 2.4 years were evaluated, with 73 of the players being baseball pitchers. Players in the double button group more frequently received palmaris longus autografts (78% vs. 30%) and less frequently received gracilis autografts (22% vs. 58%) compared with players in the docking group (P = .001); however, all other demographic factors were similar between the groups. All players in the double button group were able to RTS in 11.1 ± 2.6 months, whereas 96% of players in the docking group were able to RTS in 13.5 ± 3.4 months (P > .05). All postoperative outcomes and patient-reported outcomes were statistically similar between the groups and remained similar after isolating pitchers only and after separating partial-thickness from full-thickness UCL tears (all P > .05). CONCLUSION RTS and other postoperative outcomes may be similar between baseball players who underwent UCLR with the double button technique and the docking technique. Although future research may be necessary to strengthen clinical recommendations, these findings provide the first clinical outcomes in light of a recent cadaveric study finding similar elbow strength, joint stiffness, and graft strain compared with the docking technique.

Abstract
BACKGROUND The purpose of this study was to perform a systematic review of the literature to identify Shoulder Instability Return to Sport after Injury (SIRSI) scores in athletes who underwent open Latarjet surgery, determine the reasons why athletes failed to return to play (RTP) after Latarjet surgery, and compare SIRSI scores of those who did vs. did not RTP. METHODS According to PRISMA guidelines, the PubMed, SportDiscus, and Ovid MEDLINE databases were queried to identify studies evaluating return to sport after Latarjet surgery. Study quality was assessed using the MINORS criteria. Studies were included if RTP after Latarjet surgery and a psychological factor were evaluated, with potential psychological factors including readiness to RTP and reasons for failure to RTP. RESULTS Fourteen studies, 10 of level III evidence and 4 of level IV evidence, with 1034 patients were included. A total of 978 athletes were eligible to RTP. Of these, 792 (79%) successfully returned to play and 447 (56.4%) returned to play at their previous level of play. Mean RTP time was 6.2 months. Postoperative SIRSI scores averaged 71.2 ± 8.8 at a mean of 21 months' follow-up. Postoperative SIRSI scores for those able to RTP was 73.2, whereas athletes unable to RTP scored an average of 41.5. Mean postoperative SIRSI scores for those in contact sports was 71.4, whereas those in noncontact sports was 86.5. There were 31 athletes with a documented reason why they did not RTP, with postoperative shoulder injury being the most common reason (54.5%). Fear of reinjury and feeling "not psychologically confident" each represented 6.5% of the total. CONCLUSION Athletes who RTP have higher average SIRSI scores than those who are unable to RTP. Of the athletes who documented why they did not RTP, more than half cited a shoulder injury as their reason for not returning to play, whereas fear of reinjury and lack of psychological readiness were other common reasons.

Abstract
The ulnar collateral ligament, also called the medial collateral ligament of the elbow, is the primary stabilizer against valgus loads. This ligament can be traumatically torn, such as in an elbow dislocation, or can tear through attritional damage with overhead sports. Although baseball pitching is the most common contributor, these injuries also occur with volleyball, gymnastics, and javelin throwing. Patients most commonly report a history of medial elbow pain with associated loss of command, control, and throw velocity. The ulnar nerve lies directly superficial to the posterior band of the ulnar collateral ligament and ulnar neuritis is commonly associated with ulnar collateral ligament pathology. Nonsurgical treatment, including rest from activity, flexor-pronator strengthening, and possible platelet-rich plasma injections, can be considered for partial-thickness tears. Surgical treatment can be considered for patients in whom nonsurgical treatment fails and full-thickness tears. Historically, surgical treatment involved reconstruction of the ligament with a tendon graft. Ipsilateral palmaris longus autograft has been the most commonly used graft, but contralateral palmaris, autograft hamstring tendons, and allograft tendon have also been used. This procedure has a high rate of return to play and a low complication rate, but most athletes require 12 to 18 months to fully return. More recently, repair of the ligament, with the addition of a biologic ingrowth ligament augmentation suture, has demonstrated similarly high rates of return to play and low complication rates, with a full return to play in 6 months.

Abstract
Aims The aim of this study was to establish consensus statements on medial patellofemoral ligament (MPFL) reconstruction, anteromedialization tibial tubercle osteotomy, trochleoplasty, and rehabilitation and return to sporting activity in patients with patellar instability, using the modified Delphi process. Methods This was the second part of a study dealing with these aspects of management in these patients. As in part I, a total of 60 surgeons from 11 countries contributed to the development of consensus statements based on their expertise in this area. They were assigned to one of seven working groups defined by subtopics of interest. Consensus was defined as achieving between 80% and 89% agreement, strong consensus was defined as between 90% and 99% agreement, and 100% agreement was considered unanimous. Results Of 41 questions and statements on patellar instability, none achieved unanimous consensus, 19 achieved strong consensus, 15 achieved consensus, and seven did not achieve consensus. Conclusion Most statements reached some degree of consensus, without any achieving unanimous consensus. There was no consensus on the use of anchors in MPFL reconstruction, and the order of fixation of the graft (patella first versus femur first). There was also no consensus on the indications for trochleoplasty or its effect on the viability of the cartilage after elevation of the osteochondral flap. There was also no consensus on postoperative immobilization or weightbearing, or whether paediatric patients should avoid an early return to sport.

Abstract
Aims The aim of this study was to establish consensus statements on the diagnosis, nonoperative management, and indications, if any, for medial patellofemoral complex (MPFC) repair in patients with patellar instability, using the modified Delphi approach. Methods A total of 60 surgeons from 11 countries were invited to develop consensus statements based on their expertise in this area. They were assigned to one of seven working groups defined by subtopics of interest within patellar instability. Consensus was defined as achieving between 80% and 89% agreement, strong consensus was defined as between 90% and 99% agreement, and 100% agreement was considered to be unanimous. Results Of 27 questions and statements on patellar instability, three achieved unanimous consensus, 14 achieved strong consensus, five achieved consensus, and five did not achieve consensus. Conclusion The statements that reached unanimous consensus were that an assessment of physeal status is critical for paediatric patients with patellar instability. There was also unanimous consensus on early mobilization and resistance training following nonoperative management once there is no apprehension. The statements that did not achieve consensus were on the importance of immobilization of the knee, the use of orthobiologics in nonoperative management, the indications for MPFC repair, and whether a vastus medialis oblique advancement should be performed.

Abstract
Background The impact of single-sport specialization on performance and injury risk in youth and adolescent athletes remains debated. The purpose of this study was to determine the incidence of single-sport specialization and its association with pitch velocity, pitcher utilization, range of motion, strength, and injury history. Methods High school pitchers in the Northeastern, Southeastern, Midwestern, and Western Regions of the United States were prospectively recruited. Prior to the season, pitchers were surveyed about their basic demographics, sport participation history, and injury history. At this timepoint, a standardized physical examination was performed and max pitch velocity was measured. They were then prospectively followed over the ensuing high school season, where pitch utilization and counts were followed and injuries were tracked. Results Across the study, 115 pitchers were recruited, of whom 53% played baseball as their only sport and 47% played other sports. Single- position specialization within baseball was uncommon as 90% of athletes played positions other than pitcher. There were no differences in range of motion, strength, or pitch velocity between multisport athletes and single-sport specialists. Within the multisport group, 26% reported a history of injury, while 38% of the single-sport specialists reported a history of injury (P = .179). There were no significant differences in pitcher utilization between multisport athletes and single-sport specialists. Only a single prospective injury occurred in the 115 players. Conclusion Although single-sport specialization is common, nearly half of all high school pitchers in this study were multisport athletes. While injury history was generally similar between the two groups, single-sport baseball players did not have the following: improved motion, increased strength, higher ball velocity, or greater pitching volumes during the high school baseball season compared to multisport athletes. Accordingly, single-sport specialization did not have a competitive advantage for these high school pitchers based on the performance factors studied. Further prospective studies are necessary to understand the association between single-sport specialization and injury risk in high school baseball players.

Abstract
BACKGROUND Stress ultrasonography (SUS) has provided clinicians with an alternative means of evaluating ulnar collateral ligament (UCL) injury by dynamically assessing ulnohumeral joint space gapping under applied valgus stress. However, 3 previous cadaveric studies have evaluated the biomechanical effect of partial UCL tears at different anatomic locations with conflicting results. PURPOSE/HYPOTHESIS The purpose of this study was to use in vivo data from patients with magnetic resonance (MR)-confirmed partial UCL tears to determine if anatomic partial tear location influenced the resultant stability of the elbow in terms of ulnohumeral joint gapping on SUS. It was hypothesized that no difference would be seen in the amount of ulnohumeral joint gapping based on MR-identified anatomic partial UCL tear location. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All patients diagnosed with elbow injury from 2015 to 2020 were screened to identify competitive baseball pitchers with a partial UCL tear who received an SUS. Partial UCL tear was diagnosed via surgeon and radiologist interpretation of elbow MR imaging (MRI) as well as confirmation at the time of surgery as documented in the operative report. Demographic, injury, and treatment data were collected from the clinic notes, MRI reports, and stress ultrasound reports. Ulnohumeral joint gapping on SUS was calculated as the difference between ulnohumeral joint gapping without valgus stress versus ulnohumeral joint gapping with valgus stress (delta) as performed by a musculoskeletal radiologist. RESULTS Overall, 60 male baseball pitchers (age, 19.2 ± 2.1 years), including 22 (37%) high school, 26 (43%) collegiate, and 12 (20%) professional pitchers, were evaluated. Regarding the location of partial UCL tears, 32 (53%) pitchers had proximal tears and 28 (47%) had distal tears. The mean delta value cohort was 2.1 ± 1.1 mm, and 34 pitchers (57%) had delta values >2.0 mm. Ulnohumeral joint gapping (high school [1.9 mm] vs collegiate [2.6 mm] vs professional [1.6 mm]; P = .004) and the percentage of pitchers with delta values >2.0 mm (45% vs 77% vs 33%; P = .017) differed based on level of competition. After controlling for age, body mass index, and level of competition in a multivariate linear regression, tear location was not related to ulnohumeral joint gapping (P = .499). CONCLUSION No difference was observed in the amount of ulnohumeral joint gapping on SUS in symptomatic baseball pitchers with MR-identified partial UCL tears at differing anatomic locations. The findings of this study are contrary to previous cadaveric studies that have evaluated the effects of UCL tear characteristics on delta laxity.

Abstract
Background Although pitch count and rest guidelines have been promoted for youth and adolescent baseball players for nearly 2 decades, compliance with guidelines remains poorly understood. Purpose/Hypothesis The purpose of this study was to determine the frequency of compliance with Major League Baseball (MLB) Pitch Smart guidelines as well as the association between compliance and range of motion (ROM), strength, velocity, injury, and pitcher utilization. It was hypothesized that pitchers in violation of current recommendations would have increased strength, velocity, and injury. Study Design Case-control study; Level of evidence, 3. Methods This was a prospective, multicenter study of 115 high school pitchers throughout the United States. Pitchers were surveyed about their compliance with current off-season, rest-related guidelines, and history of injury. During the preseason, pitchers underwent standardized physical examinations, and pitch velocity was measured. Pitch counts were collected during the baseball season that followed. Dynamometer strength testing of shoulder forward flexion, and external rotation as well as grip strength was recorded. We compared pitchers who were compliant with recommendations with those who were noncompliant using Student t and Mann-Whitney U tests. Results Based on preseason data, 84% of pitchers had violated current Pitch Smart guidelines. During the season, 14% had at least 1 violation of the Pitch Smart guidelines. Across both the preseason survey and in-season pitch counts, 89% of players had at least 1 violation of the Pitch Smart guidelines. While there were no significant differences in ROM or strength, the noncompliant group had higher maximum pitch velocity than the compliant group (74 ± 8 vs 69 ± 5 mph [119 ± 13 vs 111 ± 8 kph], respectively; P = .009). Players' self-reported velocity differed significantly from the direct measurement, for both peak velocity (80 ± 6 vs 73 ± 8 mph [129 ± 9 vs 117 ± 13 kph], respectively; P < .001) and mean velocity (73 ± 8 vs 53 ± 27 mph [117 ± 13 vs 85 ± 43 kph], respectively; P < .001). Conclusion Most high school pitchers were not fully compliant with current Pitch Smart guidelines, and they tended to overestimate their peak velocity by 7 mph (11 kph). Pitchers who threw with greater velocity were at higher risk for violating Pitch Smart recommendations.

Abstract
Background Elbow capsular release can be performed arthroscopically or through an open method to improve range of motion (ROM). However, it is unclear how frequently patients require an open capsular release after unsatisfactory results from an arthroscopic release. Purpose/Hypothesis The purpose of this study was to determine the percentage of patients who underwent an arthroscopic elbow release for loss of motion who then required a repeat elbow capsular release or other subsequent surgery on the same elbow. It was hypothesized that patients who underwent arthroscopic elbow release would rarely (<5%) require a subsequent elbow release. Study Design Case series; Level of evidence, 4. Methods Patients who underwent arthroscopic elbow capsular release from January 1, 2010, to December 31, 2019, were identified by chart review and procedure code. Demographic parameters, pre- and postoperative ROM, and surgical history were collected by chart review. Follow-up data included patient satisfaction and the Timmerman-Andrews (TA) elbow score. Data were compared between patients who did and those who did not require subsequent elbow surgery. Results Overall, of 140 study patients (116 male, 24 female; mean age, 49.6 years), 18 (12.9%) required subsequent surgery, including 6 capsular releases (4.3%; 1 open and 5 arthroscopic). The most common follow-up procedure was ulnar nerve releases/transpositions (n = 7). Total arc of elbow motion (flexion to extension) improved by a mean of 51.4°. The mean TA score was 76.5 ± 20.4 at a mean of 5.25 years postoperatively. Mean satisfaction score was 77.6 ± 26.3. In this study, 82.4% of patients stated that their symptoms either improved or resolved completely. Patients who required subsequent surgery had a significantly lower preoperative total arc of elbow motion versus those who did not require subsequent surgery (P = .046). There was no difference between the groups in symptom resolution, satisfaction, ROM, or TA score (P ≥ .279 for all). Conclusion After arthroscopic elbow release, <5% of patients required a repeat elbow capsular release, 12.9% required some form of follow-up elbow surgery, and 4.3% had a new injury of the elbow. Overall, patients saw improvement in elbow ROM, but many still had residual symptoms from their underlying disease after arthroscopic elbow capsular release.

Abstract
Background Internal impingement is a common cause of shoulder pain and dysfunction in baseball pitchers. Purpose/Hypothesis The purpose of this study was to determine if the amount of rest days between outings, the number of innings pitched in each outing, and the number of batters faced in each outing are risk factors for internal impingement in professional baseball pitchers. It was hypothesized that a higher workload would significantly increase a pitcher's risk of developing internal impingement. Study Design Case-control study; Level of evidence, 3. Methods All professional (Major and Minor League) baseball pitchers who were diagnosed with internal impingement between 2011 and 2017 were identified using the Major League Baseball's Health and Injury Tracking System. A separate player usage data set was used to determine workload. The authors compared workload variables (days of rest, innings pitched, and batters faced per game) between each of 4 injury-exposure groups (pitchers with documented internal impingement <2, <6, <12, and >12 weeks after a game) and a control group of pitchers with no internal impingement using Student t tests or Mann-Whitney U tests. In a within-pitcher paired analysis of the injury groups, the workload variables during 3 acute periods (<2, <6, and <12 weeks preinjury) were compared with the baseline values (>12 weeks preinjury). Results Overall, there were 624 professional baseball pitchers diagnosed with internal impingement during the study period. Compared with pitcher games (n = 213,964), pitchers in all 4 injury-exposure groups had significantly more innings pitched per game (P ≤ .003 for all) and faced significantly more batters per game (P < .001 for all). There were significantly more starting pitchers in each of the injury-exposure groups when compared with the controls (P < .001 for all). However, when comparing acute and baseline workloads in the pitchers diagnosed with internal impingement, there were no significant differences in the number of innings pitched, batters faced, or days of rest. Conclusion This analysis revealed significantly greater pitcher workload and percentage of starting pitchers in professional baseball players diagnosed with internal impingement when compared with healthy controls. However, this injury did not seem to be associated with an acute increase in workload.

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

Abstract
BACKGROUND Studies have shown that utilization and outcomes after shoulder arthroplasty vary by sociodemographic factors, highlighting disparities in care. This systematic review synthesized all available literature regarding the relationship between utilization and outcomes of shoulder arthroplasty and race/ethnicity. METHODS Studies were identified using PubMed, MEDLINE (through Ovid), and CINAHL databases. All English language studies of Level I through IV evidence that specifically evaluated utilization and/or outcomes of hemiarthroplasty, total shoulder arthroplasty, or reverse shoulder arthroplasty by race and/or ethnicity were included. Outcomes of interest included rates of utilization, readmission, reoperation, revision, and complications. RESULTS Twenty-eight studies met inclusion criteria. Since the 1990s, Black and Hispanic patients have demonstrated a lower utilization rate of shoulder arthroplasty compared with White patients. Although utilization has increased among all racial groups throughout the present decade, the rate of increase is greater for White patients. These differences persist in both low-volume and high-volume centers and are independent of insurance status. Compared with White patients, Black patients have a longer postoperative length of stay after shoulder arthroplasty, worse preoperative and postoperative range of motion, a higher likelihood of 90-day emergency department visits, and a higher rate of postoperative complications including venous thromboembolism, pulmonary embolism, myocardial infarction, acute renal failure, and sepsis. Patient-reported outcomes, including the American Shoulder and Elbow Surgeon's score, did not differ between Black and White patients. Hispanics had a significantly lower revision risk compared with White patients. One-year mortality did not differ significantly between Asians, Black patients, White patients, and Hispanics. CONCLUSION Shoulder arthroplasty utilization and outcomes vary by race and ethnicity. These differences may be partly due to patient factors such as cultural beliefs, preoperative pathology, and access to care, as well as provider factors such as cultural competence and knowledge of health care disparities.

Abstract
Background Weighted-ball velocity training programs are popular but may be associated with increased injury risk. The purpose of this study was to determine the current frequency of these programs, as well as their association with range of motion, strength, velocity, injury, and utilization in high school baseball pitchers. Methods This was a multicenter, prospective, community-based study including high schools from the Northeastern, Southeastern, Midwestern, and Western regions of the United States. Preseason pitchers were surveyed about their use of weighted ball velocity programs and history of injury. Preseason pitchers underwent standardized physical examinations and pitch velocity was measured. During a single high school season, pitch counts and injury incidence were prospectively collected. Results In total, 115 pitchers were recruited, of whom 63% had participated in a weighted ball program. There were no differences in range of motion or strength between groups who used weighted balls and those who did not. Pitchers that utilized weighted ball programs demonstrated a higher average fastball velocity (114.26 vs. 106.22 km/h [71 vs. 66 mph]; P < .001) as well as peak fastball velocity (115.87 vs. 109.44 km/h [72 vs. 68 mph]; P = .001) compared to those that did not use weighted ball programs. Pitchers that utilized weighted ball programs were no more likely to be single-sport athletes (44%) than those who were multisport athletes (49%, P = .667). Within the group who had used a weighted ball program 29% (13/45) reported a history of injury and within the group who had not used a weighted ball program 25% (10/40) reported a history of injury (P = .687). As only a single injury occurred in the entire cohort, comparison of injury rates could not be completed. Conclusion In this prospective study, the majority of high school pitchers reported using weighted ball programs to increase velocity, and these programs were associated with increased average and peak velocity compared to pitchers who did not use weighted ball programs. There were no significant differences in injury history between the 2 groups. Further study is necessary to understand the injury risk associated with weighted ball programs.

Abstract
Background Pitch counts are tightly monitored in Major League Baseball (MLB). Hidden pitches-including warm-up pitches before and between innings and pitches before the starting/relieving pitcher's appearance in a game-are not as closely monitored. Purpose/Hypothesis To report the number of hidden pitches thrown per game and over the course of a season for a single organization. We hypothesized that players who threw more hidden pitches would be at an increased risk of injury compared with those who threw fewer hidden pitches. Study Design Case-control study; Level of evidence, 3. Methods All pitchers who played for a single MLB organization in the 2021 season were included. Hidden pitches, in-game pitches, and total pitches thrown during all games in the season were recorded. Injuries to these pitchers were also recorded. Players were defined as having an injury if they spent any time on the injured list. Results Overall, 137 pitchers were included, 66 (48%) of whom sustained an injury and were placed on the IL during the 2021 season (mean time on IL, 53.6 ± 45.6 days). Of the 66 players who sustained an injury, 18 (27.3%) sustained an elbow injury, while 12 (18.2%) sustained a shoulder injury. Only 1 player sustained an ulnar collateral ligament tear. When comparing hidden pitches, in-game pitches, and total pitches between pitchers who sustained an injury and those who did not, there were no significant differences between groups (P = .150; P = .830; and P = .377, respectively). On average, hidden pitches made up 45.4% of the total number of pitches thrown during the course of the season. When evaluating the number of hidden pitches as a percentage of the total number of pitches thrown in a season, there was no significant difference between pitchers who sustained an injury and those who did not (P = .654). Conclusion MLB pitchers who sustained an injury did not throw more hidden pitches than those who did not sustain an injury. Larger scale studies are needed to confirm the results of this single-team study.

Abstract
Background Purposeful rehabilitation before surgery (prehabilitation) has been researched and implemented in the treatment of anterior cruciate ligament tears. However, it is unclear whether prehabilitation would affect outcomes for baseball pitchers with partial ulnar collateral ligament (UCL) tears. Purpose/Hypothesis The purpose of this study was to determine whether baseball pitchers with partial UCL tears who completed ≥4 weeks of prehabilitation (prehab group) have different return to play (RTP) outcomes than pitchers with 0 to 3 weeks of preoperative physical therapy (no prehab group). We hypothesized that pitchers in the prehab group would have similar RTP rates compared with pitchers in the no prehab group. Study Design Cohort study; Level of evidence, 3. Methods Baseball pitchers of all competitive levels who underwent primary UCL reconstruction (UCLR) or UCL repair between 2010 and 2019 were included. Physician chart notes, magnetic resonance images, and operative notes were screened to confirm primary UCLR or UCL repair of a partial UCL tear and to identify whether the nonoperative treatment had been attempted. Patients were contacted via RedCap for postoperative complications, reoperations, RTP, and patient-reported outcomes (Kerlan-Jobe Orthopaedic Clinic score, Andrews-Timmerman score, Conway-Jobe score, and satisfaction). Results Overall, 105 baseball pitchers (n = 55 prehab group; n = 50 no prehab group) were included and evaluated at 3.4 ± 2.5 years postoperatively. Six pitchers underwent UCL repair, and 99 pitchers underwent UCLR. All demographic characteristics were similar between groups except the prehab group received a gracilis graft more frequently (76.5% vs 51.2%; P = .038). The RTP rate (prehab [88.1%] vs no prehab [93.8%]; P = .465) was similar between groups. All other postoperative outcomes were also similar between groups, including revision rates and patient-reported outcomes. Conclusion Postoperative and patient-reported outcomes did not differ significantly between pitchers with partial UCL tears who performed rehabilitation before UCL surgery and pitchers who did not attempt a significant period of rehabilitation before UCL surgery. Clinicians should feel comfortable recommending rehabilitation for patients with partial UCL tears who wish to attempt a period of nonoperative treatment, as postoperative outcomes are not affected if UCL surgery is later needed.

Abstract
BACKGROUND Injury of the ulnar collateral ligament (UCL) has become increasingly common, particularly in overhead athletes. There is no consensus on management of the ulnar nerve in UCL reconstruction (UCLR) in patients with preoperative ulnar nerve symptoms, as literature supports both not decompressing the nerve as well as ulnar nerve transposition (UNT). HYPOTHESIS/PURPOSE The purpose of this study was to compare subjective clinical outcomes and return-to-sports (RTS) metrics between patients who received UNT during UCLR and a matched cohort who underwent UCLR alone. We hypothesized that there would be no significant difference in patient outcomes or RTS metrics between the cohorts. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Using an institutional database, patients who underwent UCLR with UNT between 2007 and 2017 were retrospectively identified. These patients were matched based on sex, age at surgery (±3 years), and body mass index (±2 kg/m2) to a comparison group that underwent UCLR alone. Patients completed the Kerlan-Jobe Orthopaedic Clinic Shoulder & Elbow (KJOC) score, the Timmerman and Andrews elbow score, the Conway-Jobe scale, and custom patient satisfaction and RTS questionnaires. RESULTS Thirty patients who underwent UCLR with concomitant UNT and 30 matched patients who underwent UCLR without UNT were available for follow-up at a mean of 6.9 (3.4-9.9) and 8.1 (3.4-13.9) years, respectively. The UNT group reported similar KJOC (78.4 in UNT vs 76.8; P = .780), Conway-Jobe (60% excellent in UNT vs 77% excellent; P = .504), Timmerman and Andrews (86.2 in UNT vs 88.8; P = .496), and satisfaction scores (85.3% in UNT vs 89.3%; P = .512) compared with UCLR group. In terms of RTS rate (84% in UNT vs 93% in UCLR; P = .289) and duration required to RTS (11.1 months in UNT vs 12.5 months in UCLR; P = .176), the 2 groups did not significantly differ. Finally, despite significant differences in preoperative ulnar nerve symptoms (100% in UNT vs 7% in UCLR; P < .001), the 2 groups did not statistically differ in the proportion of patients who experienced postoperative ulnar nerve symptoms (13% in UNT vs 0% in UCLR; P = .112). CONCLUSION This matched cohort analysis showed no statistically significant differences in patient-reported outcomes and RTS between patients undergoing UCLR with and without UNT.

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

Abstract
PURPOSE The purpose of this study was to establish consensus statements on the treatment of UCL injuries and to investigate whether consensus on these distinct topics could be reached. METHODS A modified consensus technique was conducted among twenty-six elbow surgeons and 3 physical therapists/athletic trainers. Strong consensus was defined as 90-99% agreement. RESULTS Of the 19 total questions and consensus statements 4 achieved unanimous consensus, 13 achieved strong consensus, and 2 did not achieve consensus. CONCLUSION There was unanimous agreement that the risk factors include overuse, high velocity, poor mechanics, and prior injury. There was unanimous agreement that advanced imaging in the form of either an MRI or MRA should be performed in a patient presenting with suspected/known UCL tear that plans to continue to play an overhead sport, or if the imaging study could change the management of the patient. There was unanimous agreement regarding lack of evidence for the use of orthobiologics in the treatment of UCL tears as well as the areas pitchers should focus on when attempting a course of non-operative management. The statements that reached unanimous agreement for operative management were regarding operative indications and contraindications for UCL tears, prognostic factors that should be taken into consideration in when performing UCL surgery, how to deal with the flexor-pronator mass during UCL surgery and use of an internal brace with UCL repairs. Statements that reached unanimous agreement for RTS were regarding: portions of the physical exam should be considered when determining whether to allow a player to RTS, unclear how velocity, accuracy, and spin rate should be factored into the decision of when players can RTS and sports psychology testing should be used to determine whether a player is ready to RTS. LEVEL OF EVIDENCE Expert opinion (Level V).

Abstract
BACKGROUND Ulnar Collateral Ligament (UCL) tears are common in baseball players. When non-operative management fails; reconstruction or repair may be necessary to restore physical function. There is no clear consensus regarding the indications for surgery based on magnetic resonance imaging (MRI) tear characteristics, or the indications for selecting repair over reconstruction. The purpose of this study was to define the indications for UCL surgery based on MRI and to elucidate indications for UCL repair vs reconstruction. METHODS Twenty-six orthopedic surgeons who treat baseball players were surveyed. Forty-five MRIs were reviewed: 15 without UCL tears, 15 with intra-operatively confirmed partial-thickness tears, and 15 with full-thickness tears. Factors investigated included ligament characteristics (peri-ligamentous or osseous edema, ligament hypertrophy, calcification, partial or full-thickness tearing) and location (proximal, mid-substance, or distal). Surgeons were given a clinical scenario and asked whether 1) surgery was indicated and 2) whether repair or reconstruction was recommended. Odds ratios (OR) and 95% confidence intervals (95%CI) helped identify significant predictors for both queries. RESULTS The odds of recommending surgical treatment compared to non-operative treatment were 2.4x more likely for a proximal partial-thickness tear, 3.2x for distal partial-thickness tear, 5.1x for distal full-thickness tear, and 7.0x for proximal full-thickness tear (p<0.001). Significant indications for repair included distal partial (OR=1.6, 95%CI 1.0, 2.1, p<0.001) and full-thickness tears (OR=1.7, 95%CI 1.1, 2.3, p<0.001). Repair was 3x less likely recommended for mid-substance full-thickness tears (OR=3.0, 95%CI -5.0, -1.0, p=0.004). Ultrasound stress testing was requested in 78% of partial tears. CONCLUSIONS Among surgeons surveyed, the highest odds for recommending operative treatment were proximal full-thickness tears, then distal full-thickness, distal partial-thickness, and proximal partial-thickness tears. Repair was most appropriate for partial and full-thickness distal tears, but relatively contraindicated for complete mid-substance UCL tears. Ultrasound stress testing was frequently requested for partial tears. Given the lack of consensus among surgeons, future prospective registries are necessary to determine whether these factors associate with clinical outcomes.

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

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

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

Abstract
Background The ulnar collateral ligament (UCL) of the elbow is subject to repetitive stress in overhead throwing athletes. This can lead to morphologic changes at the bony attachments of the UCL and hypertrophy of the sublime tubercle. The purpose of this case series is to describe the surgical details and clinical outcomes of a series of competitive baseball pitchers with hypertrophic sublime tubercles who underwent UCL reconstruction (UCLR). Methods All baseball pitchers who were treated for UCL injuries with significant hypertrophy of the sublime tubercle on preoperative imaging were included in the series. Clinical history, preoperative imaging, intraoperative findings during UCLR, and postoperative outcomes measured with the Conway scale were described. Results Ten players (average age of 22.9 years [range 13-39]) were included (average follow-up 20.4 months [range 3-38 months]). Five patients also had symptoms of ulnar nerve compression, with 4 requiring transposition at the time of ULCR and 1 at 3 months postoperatively. Bony hypertrophy of the sublime tubercle was confirmed intraoperatively in all cases and excised before UCLR with the docking technique. Of the 7 patients with at least 12-month follow-up postoperatively, 6 had excellent outcomes, and 1 had a fair outcome. Conclusion Although UCLR in the setting of hypertrophic sublime tubercle can be more complex than typical UCLR, excellent outcomes are achievable with preoperative recognition and surgical planning.

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

Abstract
BACKGROUND Ulnar collateral ligament (UCL) reconstruction (UCLR) is a common surgery among baseball pitchers. UCL repair combined with augmentation using high-strength tape, referred to as an internal brace, was developed as an alternative to UCLR in select patients with the benefit of allowing these athletes to return to sport (RTS) faster. A combined UCLR with an internal brace may allow players indicated for a UCLR to RTS more expeditiously. METHODS Twenty-four cadaveric elbows were divided into 3 groups: 12 specimens into the modified docking (MD) group, 6 into the double-docking (DD) group, and 6 into the double docking with internal brace augmentation (DDA) group. This allowed a 1:1 comparison of the MD to the DD and the MD to the DDA. Valgus cyclic testing of native and reconstructed specimens was executed at 90° elbow flexion. After preconditioning, all specimens were cycled between 2 and 10 Nm for 250 cycles. Reconstructed specimens continued to a torque test to catastrophic failure step. Outcome data included intracyclic stiffness, maximum cyclic rotational displacement, gap formation, and failure torque. RESULTS Cyclic stiffness of the constructs remained constant throughout the entirety of the torque-controlled cycling phase. The DDA group resulted in a 38% increase in cyclic stiffness from native testing (not statistically significant) and a statistically significant 54% increase from the MD (P = .002). The DDA mean cyclic stiffness was significantly greater than the Native (P < .001), DD (P = .025), and MD (P < .001) groups. Between reconstruction groups, mean gap formation was greatest among the MD group (2.51° ± 1.59°) and least for the DDA group (1.01° ± 0.57°) but did not reach statistical significance. CONCLUSION Tape augmentation to the modified UCLR (DDA group) improved cyclic stiffness and reduced gap formation compared with the MD group.

Abstract
Background and Hypothesis Glenohumeral internal rotation deficit has been identified as a significant risk factor for upper-extremity injuries in pitchers across all ages. Humeral retroversion (HR), posterior capsule thickness (PCT), and posterior rotator cuff muscle pennation angle (PA) have been independently associated with internal rotation range of motion (IR ROM); however, these anatomic structures have not been collectively measured in baseball pitchers to determine the underlying mechanisms responsible for IR ROM. Therefore, the purpose of this study was to determine the contributions of HR, PCT, and posterior rotator cuff PA on IR ROM during a preseason evaluation in healthy professional baseball pitchers. The authors hypothesized that HR, PCT, and posterior rotator cuff PA would have a significant contribution to IR ROM. Methods This is a cross-sectional study. Healthy professional pitchers from a single organization were recruited at the beginning of the 2021 Major League Baseball Spring Training. Participants received bilateral IR ROM assessment while laying supine with the shoulder at 90 degrees of abduction and the scapula stabilized. Ultrasound imaging was also performed bilaterally to assess HR, PCT, infraspinatus (superficial + deep) PA, and teres minor (superficial + deep) PA. All ultrasound imaging processes were performed utilizing previously published, highly reliable techniques. A stepwise regression was performed, which included both arms to determine the mechanisms of IR ROM. Results Overall, 49 pitchers (88 shoulders) with an average age of 22.5 ± 2.2 years were included in the final data analysis. Stepwise linear regression found that only HR and PCT were associated with the preseason IR ROM. There was a moderate relationship between HR and PCT relative to IR ROM (R = 0.535, P < .001). Conclusion HR and PCT were found to be the primary mechanisms responsible for the preseason glenohumeral IR ROM. The posterior rotator cuff was not found to be significantly related to IR ROM. Future research evaluating these anatomic structures longitudinally-both acutely and chronically-will help clinicians optimize ROM management throughout the season. As glenohumeral internal rotation deficit can have harmful effects in baseball pitchers, understanding which anatomic structures are most responsible for IR ROM is important for injury prevention and treatment.

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 Both beach-chair and lateral decubitus patient positioning are often utilized for shoulder arthroscopy, with each offering its unique advantages and disadvantages. The surgical position is often selected according to each surgeon's preference, with no clear superiority of one position over the other. PURPOSE/HYPOTHESIS The purpose was to compare clinical and patient-reported outcomes between patients who underwent arthroscopic posterior labral repair in the beach-chair versus the lateral decubitus position. We hypothesized that patient positioning would not affect clinical and patient-reported outcomes. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A list of all patients diagnosed with the Current Procedural Terminology codes 29806 and 29807 between 2015 and 2019 was obtained from the medical records. Patients were only included if arthroscopic posterior labral repair with or without concomitant superior labral anterior to posterior repair was confirmed. Data collected for eligible patients included the number of anchors used, perioperative and postoperative complications, redislocations, subjective instability, reoperation, and revision. Patients were also contacted to complete several patient-reported outcome surveys. Preoperative data, perioperative data, and postoperative outcomes were compared between patients who underwent surgery in the beach-chair versus lateral decubitus position. RESULTS Overall, 126 patients were included-69 patients underwent surgery in the lateral decubitus position and 57 in the beach-chair position-with a mean follow-up of 2.6 ± 1.7 years. There were no significant pre- or perioperative differences between groups. Rates of postoperative dislocations, subjective instability, reoperations, revisions, all complications, and return to sports rates also did not differ between groups (all, P > .05). Finally, there was no difference between groups regarding postoperative pain, function, and subjective instability scores (all, P > .05). Results of the multivariate regression analysis showed that increased age was a weak independent risk factor for subjective recurrent posterior shoulder instability (odds ratio, 1.04; P = .036). CONCLUSION Surgical positioning for arthroscopic posterior shoulder labral repair did not affect postoperative clinical and patient-reported outcomes. Both beach-chair and lateral decubitus position provided good outcomes for posterior shoulder labral repair, with an overall recurrence rate of 8.7%. Increased age was a weak independent risk factor for subjective recurrent instability.

Abstract
BACKGROUND Medial epicondylitis (ME) is a pathological condition that arises in laborers and athletes secondary to repetitive wrist flexion and forearm pronation causing degeneration of the common flexor tendon. Although nonoperative management has demonstrated high rates of success, no standardized surgical technique has been established for situations when operative management is indicated. PURPOSE/HYPOTHESIS The purpose of this study was to perform a systematic review of the surgical treatment options for ME and evaluate the associated patient-reported outcomes (PROs). We hypothesized that surgical management of ME would vary across studies but no technique would prove to be superior. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS Searches were conducted using PubMed, EMBASE, Cumulative Index of Nursing Allied Health Literature (CINAHL), SPORTDiscus, and Cochrane databases between 1980 and April 2020. All level 1 to 4 studies were identified that focused on surgical management and PROs in the setting of ME. Description of surgical technique and PROs were required for inclusion. Investigators independently dually abstracted and reviewed the studies for eligibility. Weighted means were calculated for demographic characteristics and available PROs. RESULTS Overall, 851 studies were identified according to the search criteria. A total of 16 studies met the inclusion and exclusion criteria and therefore were evaluated. Three surgical techniques were found: open (13 studies), arthroscopic (2 studies), and percutaneous (1 study). Descriptions of the open technique were subdivided into those with (7 studies) and without (6 studies) common flexor tendon repair. Analysis included 479 elbows; patients were primarily male (58.3%) with a weighted mean age of 47.2 years. Weighted mean follow-up was 4.6 years. Tennis and manual laborer were the most common sport and occupation, respectively. Surgical success ranged from 63% to 100%, with a low complication rate of 4.3%. Success rates for return to sports and work were 81%-100% and 66.7%-100%, respectively, and only 1 study reported a return to work rate <90%. CONCLUSION This systematic review demonstrates that surgical intervention for refractory ME often has a high success rate. Regardless of surgical technique performed, patients generally demonstrated an improvement in PROs, and an encouraging number returned to work with limited complications. Further investigation is necessary to determine superiority among open, arthroscopic, and percutaneous techniques.

Abstract
Background: The coronavirus 2019 (COVID-19) pandemic resulted in the cancellation of the
2020 National Football League (NFL) preseason and a decreased preseason
roster size. The effect of this disruption on athlete injury rates is
unknown. Purpose/Hypothesis: The purpose was to quantify the rates of anterior cruciate ligament (ACL),
Achilles tendon, and hamstring tendon injuries in NFL players before and
after the COVID-19 pandemic. We hypothesized that injury rates in the 2020
season would be higher than those seen prepandemic. Study Design: Descriptive epidemiology study. Level of evidence, 4. Methods: An online search using publicly available data was carried out to identify
all NFL players who sustained an ACL, Achilles tendon, or hamstring tendon
injury between April 1, 2017, and March 31, 2021. Data collected included
player characteristics as well as career and season of injury workloads. Results: The number of Achilles tendon (27 vs 20; P = .024) and
hamstring tendon (186 vs 149; P < .001) injuries,
respectively, in the 2020 NFL season were significantly higher than the
average of the 2017 to 2019 seasons. However, the number of ACL injuries
sustained remained constant (43 vs 46; P = .175). More than
half (52.9%) of ACL injuries in the 2017 to 2019 seasons occurred in the
preseason, while most of the injuries (34.9%) in the 2020 season occurred in
weeks 1 to 4. There was no player characteristic or career workload variable
collected that was significantly different for players who sustained an ACL,
Achilles tendon, or hamstring tendon injury in the 2020 NFL season compared
with the 2017 to 2019 seasons. Conclusion: In the 2020 NFL season, the number of Achilles tendon and hamstring tendon
injuries rose while the number of ACL injuries remained constant compared
with the 2017 to 2019 seasons. Injuries that occurred during the first 4
games of the 2020 NFL season were consistent, with higher rates of injuries
seen in the preseason in previous years.

Abstract
Background: Meniscal repair is an effective treatment option for certain meniscal injuries to preserve meniscal function and limit the progression of knee osteoarthritis. Outcomes after meniscal repair in professional baseball players are not well documented. Purposes/Hypothesis: The purposes of this study were to determine performance and return to sport (RTS) in professional baseball players after meniscal repair and compare the results of medial versus lateral meniscal repair. It was hypothesized that there would be a high RTS rate, with no difference in the rate or timing of RTS between players who underwent medial versus lateral meniscal repair. Study Design: Cohort study; Level of evidence, 3. Methods: All professional baseball players who underwent meniscal repair between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Descriptive information and performance data (before and after injury) for each player were recorded. The rate and timing of RTS were then compared between players who underwent medial versus lateral meniscal repair. Results: Included were 31 patients (mean age, 24 ± 3 years). There were 6 players (19%) who had failed repair, underwent subsequent meniscectomy within 2 years of meniscal repair, and were thus excluded from the performance analysis. Of the remaining 31 players, 68% returned to the same or a higher level of play, and 6% of players returned to a lower level of play. Most repair procedures (60%) were performed using the all-inside technique, and 72% of players underwent lateral meniscal repair. The mean time missed was 187 ± 67 days, and the mean time to RTS at full competitive play was 209 ± 84 days. There were no significant differences in the rate or timing of RTS between players who underwent medial versus lateral meniscal repair (P ≥ .999 and P = .574, respectively). Pitchers saw a decrease in usage but no change in performance after meniscal repair. For batters, most metrics were unchanged, but there was a significant decrease in base stealing and on-base percentage after surgery. Conclusion: The RTS rate after meniscal repair in Major League Baseball players was 74% at a mean of 209 days; 19% of players had failed repair and underwent subsequent meniscectomy within 2 years of repair. No difference in the rate or timing of RTS was observed between players who underwent medial versus lateral meniscal repair.

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

Abstract
BACKGROUND The influence of player workload on hamstring and calf injuries in professional baseball players remains unknown. HYPOTHESIS Increased workload would significantly increase hamstring and calf strain injury risk. STUDY DESIGN Case-control. LEVEL OF EVIDENCE Level 3. METHODS All professional baseball players who sustained a hamstring or calf injury between 2011 and 2017 were identified using the Major League Baseball (MLB) Health and Injury Tracking System (HITS). A separate player usage dataset was used to determine workload. We then compared these variables between player games 2, 6, 12, and >12 weeks before a documented calf strain to player games from a noncalf injury control group. In a paired analysis, we compared the acute workload (2, 6, and 12 weeks) before injury with the injured player's workload >12 weeks before injury. RESULTS There were 175 unique calf strains (71% occurred in position players) and 1042 unique hamstring strains (97.8% occurred in position players) documented in the MLB HITS database from 2011 to 2017. In all time periods, position players with fewer days rest, more innings fielded, and more plate appearances were associated with a higher risk of subsequent hamstring and calf strains. Having only 1 day rest was associated with a 2.08-fold increase in percentage of players who sustained a subsequent calf strain compared with those with 4 days rest. Position players with >5 days of rest had a 4.03-fold decrease in percentage of players who sustained a hamstring strain compared with players with 1 day rest. Position players who fielded >9 innings per game had a 2.01-fold increase in percentage of players with a subsequent calf strain and a 3.68-fold increase in percentage of players who sustained a subsequent hamstring strain compared with players who only fielded 1 innings per game. CONCLUSION Position players with fewer days rest, more innings fielded, and more plate appearance per game had an increased risk of sustaining a hamstring or calf injury. CLINICAL RELEVANCE Increased workload had a direct relationship with risk of hamstring and calf strains in professional baseball players. Teams should consider more days rest for position players to avoid calf injuries.

Abstract
BACKGROUND Although reverse total shoulder arthroplasty (RTSA) has excellent reported outcomes and satisfaction, patients often have postoperative limitations in range of motion (ROM), specifically internal rotation. Increased lateralization is thought to improve ROM following RTSA. The purpose of this study was to evaluate the association between radiographic measurements of lateralization and postoperative ROM and clinical outcome scores following RTSA. The authors hypothesized that increased radiographic lateralization would be associated with improved postoperative ROM, specifically internal rotation, but have no significant association with clinical outcome scores. METHODS Patients who underwent RTSA with a 135° neck-shaft angle prosthesis and minimum 2-year clinical and radiographic follow-up were included and retrospectively reviewed. Postoperative radiographs were evaluated for several lateralization measurements including the lateralization shoulder angle (LSA), distance from the lateral border of the acromion to the lateral portion of the glenosphere, distance from the glenoid to the most lateral aspect of the greater tuberosity, and the distance from the lateral aspect of the acromion to the most lateral aspect of the greater tuberosity. Linear regression analyses were used to evaluate the independent association of each radiographic measurement of lateralization on forward flexion, external rotation, internal rotation, and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) index score at 2 years postoperation. Receiver operating characteristic (ROC) curves were constructed to identify significant thresholds of each radiographic lateralization measurement. RESULTS A total of 203 patients were included. For internal rotation, a greater LSA (P = .007), shorter acromion to glenosphere distance (meaning more glenoid lateralization) (P = .005), and a greater acromion to greater tuberosity distance (with the tuberosity more lateral to the acromion) (P = .021) were associated with improved internal rotation. Overall, ROC analysis demonstrated very little significant data, the most notable of which was the LSA, which had a significant cutoff of 82° (sensitivity 57%, specificity 68%, P = .012). CONCLUSION Of the numerous radiographic measures of lateralization after RTSA, the LSA is the most significantly associated with outcomes, including improved internal rotation and a decrease in forward flexion and ASES score. The clinical significance of these statistically significant findings requires further study, as the observed associations were for very small changes that may not represent clinical significance.

Abstract
BACKGROUND Biceps tendon pathology is common in patients with rotator cuff tears. Leaving biceps pathology untreated in rotator cuff repairs (RCRs) may lead to suboptimal outcomes. PURPOSE/HYPOTHESIS The purpose was to compare clinical outcomes between patients who underwent isolated RCR versus patients who underwent RCR with concomitant biceps treatment. It was hypothesized that there would be no difference in clinical outcomes between groups. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 244 patients who underwent RCR in 2016 were included. Patient characteristics, presence of concomitant biceps pathology, pre- and postoperative American Shoulder and Elbow Surgeons (ASES) scores, rotator cuff failure, revision surgery, and complications were recorded. RESULTS There were no significant differences between patients who underwent isolated RCR (n = 143) and those who underwent RCR with biceps treatment (n = 101) at 2 years postoperatively in ASES scores (RCR, 81.5; RCR+biceps treatment, 79.5; P = .532), cuff failure rate (5.6% vs 4.0%; P = .760), revision RCR rate (3.5% vs 2.0%; P = .703), or complication rate (11.9% vs 5.0%; P = .102). Furthermore, when comparing concomitant biceps tenotomy (n = 30) versus concomitant biceps tenodesis (n = 71), there were no differences in ASES scores (P = .149), cuff failure rate (P > .999), revision RCR rate (P > .999), or complication rate (P > .999) postoperatively. Finally, when comparing arthroscopic biceps tenodesis (n = 50) versus subpectoral biceps tenodesis (n = 21), there were no differences in ASES scores (P > .592), cuff failure rate (P > .999), revision RCR rate (P = .507), or complication rate (P > .999) 2 years postoperatively. CONCLUSION Addressing biceps pathology when performing RCR resulted in similar rates of cuff failure, revision RCR, and complications, as well as a similar improvement in patient-reported outcomes when compared with isolated RCR at 2 years postoperatively. Furthermore, when comparing tenotomy versus tenodesis and arthroscopic versus subpectoral tenodesis, comparable outcomes with regard to rate of rotator cuff repair failure, revision RCR, complications, and patient-reported outcomes were found.

Abstract
BACKGROUND Latissimus dorsi (LD) and teres major (TM) tears have become increasingly recognized injuries in professional baseball pitchers. The purpose of this study was to determine whether workload, as measured by the number of days of rest between outings, number of innings pitched, number of batters faced, and being a starting pitcher, is associated with an increased risk of sustaining an LD-TM tear in professional baseball pitchers. METHODS All professional baseball pitchers who sustained an LD-TM tear between 2011 and 2017 were identified using the Major League Baseball Health and Injury Tracking System. A separate player-usage data set was used to determine workload. We then compared workload variables between pitcher-games 2, 6, 12, and >12 weeks prior to a documented LD-TM tear and pitcher-games from a non-LD-TM tear control group. In a paired analysis, we compared the acute workload (2, 6, and 12 weeks) prior to injury and the injured pitchers' non-acute workload >12 weeks prior to injury. RESULTS A total of 224 unique LD-TM tears were documented in the Major League Baseball Health and Injury Tracking System database. In most periods, player-games with more innings pitched and more batters faced were associated with a higher incidence of subsequent LD-TM tears. The number of days of rest was not a significant predictor of an LD-TM tear in the acute workload setting, but pitchers who sustained an LD-TM injury averaged fewer days of rest over the previous ≥12 weeks than controls (P < .001). Pitchers who faced >30 batters per game showed a 1.57-fold increase in the percentage of pitchers with a subsequent LD-TM tear as compared with pitchers who faced ≤5 batters per game. Significantly more starting pitchers were in the case group that sustained LD-TM tears over multiple time points than in the control group. CONCLUSION Having a greater pitcher workload and being a starting pitcher were associated with an increased risk of sustaining LD-TM tears in professional baseball players. The average number of days of rest was only a risk factor for LD-TM tears over a 3-month or longer period.

Abstract
Purpose To retrospectively investigate the clinical and functional outcomes of patients who underwent knotted medial-row rotator cuff repair (KT-RCR) compared with patients who underwent knotless medial-row rotator cuff repair (KL-RCR). Methods A retrospective chart review of patients who underwent double-row transosseous-equivalent rotator cuff repair in 2016 was performed at a single institution with 2-year follow-up. Information regarding demographic characteristics, preoperative tear size (magnetic resonance imaging), surgical variables (including method of suture stabilization), preoperative and postoperative American Shoulder and Elbow Surgeons (ASES) scores, and all complications (e.g., cuff failure, adhesive capsulitis, and persistent pain) was compiled. Results A total of 189 patients met the inclusion criteria: 72 in the KL-RCR group and 117 in the KT-RCR group. No significant difference in preoperative ASES scores was found between the KL-RCR and KT-RCR groups (48.3 vs 45.4, P = .327). Postoperative ASES scores did not differ between the groups (82.4 for KL-RCR vs 78.8 for KT-RCR, P = .579). We found no significant difference in cuff failure rates after 2 years, determined by magnetic resonance imaging (5.6% for KL-RCR vs 6.1% for KT-RCR, P > .999), or complication rates (11.1% for KL-RCR vs 8.6% for KT-RCR, P = .743). Conclusions The knotted approach and knotless approach to double-row rotator cuff repair showed similar outcome scores, cuff failure rates, and complication rates at minimum 2-year follow-up. Level of Evidence Level III, retrospective therapeutic comparative trial.

Abstract
BACKGROUND Although results after ulnar collateral ligament reconstruction (UCLR) in baseball players have been well documented, the literature is replete regarding the outcomes after UCLR in javelin throwers. PURPOSE To report outcomes after UCLR in javelin throwers. HYPOTHESIS UCLR in javelin throwers will result in a high rate of return to play similar to that of previously published studies from athletes of other sports. METHODS All patients who were identified preoperatively as javelin throwers and underwent UCLR between 2011 and 2017 with a minimum 2-year follow-up were eligible for inclusion. Patients were assessed with the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score, Timmerman-Andrews Elbow score, Conway-Jobe score, patient satisfaction, return to sport rate questionnaire, and the occurrence of any postoperative complications. RESULTS Eighteen patients met the inclusion criteria. Complete follow-up was available in 16 (88.9%) patients. The average age at surgery was 21.2 ± 2.0 (range, 18.6-24.9) years. At the final follow-up, the average Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score and Timmerman-Andrews Elbow score were 77.3 (range, 18.7-98.4) and 91.8 (range, 70.0-100.0), respectively. Outcomes on the Conway-Jobe scale were as follows: excellent (n = 6; 37.5%), good (n = 4; 25%), fair (n = 6; 37.5%). Ten (62.5%) patients returned to play at an average of 12.2 ± 3.6 (range, 6.0-18.0) months after surgery. Two (12.5%) patients sustained a shoulder injury postoperatively; however, neither required surgery. CONCLUSION UCLR in javelin throwers results in good outcomes with a low rate of reinjury/reoperation. However, the return to play rate (62.5%) and good/excellent outcomes per the Conway-Jobe scale (68.8%) are lower than what has been previously reported in baseball players and javelin throwers. Further investigation regarding outcomes in javelin throwers after UCLR is warranted.

Abstract
BACKGROUND Injury rates in baseball players of all ages are increasing. Identifying modifiable risk factors is paramount to implementing injury prevention programs. PURPOSE/HYPOTHESIS The purpose was to evaluate the influence of weather (temperature, humidity, atmospheric pressure, and heat index) and game factors (start time, duration, single vs doubleheader) on injury rates in professional baseball players. We hypothesized that colder temperatures would be associated with significantly more injuries per game. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This was a retrospective database study. Two data sets were combined: 1 containing all injuries in Major and Minor League Baseball between 2011 and 2017 and 1 containing all games played in Major and Minor League Baseball during the same period to determine the number of injuries per game. Temperature, humidity, atmospheric pressure, and heat index were determined for each game using the data from the US Environmental Protection Agency. Additional game variables included the level of play, the turf type (natural vs artificial grass), the stadium type (open vs dome vs retractable), the game start time, the game duration, and whether the game was a doubleheader. Then, a multivariate analysis was conducted to determine which factors were associated with the number of injuries per game. RESULTS In total, our analysis included 33,587 injuries and 76,747 games. A total of 25,776 (33.6%) games contained an injury, and 41% of injuries occurred as multiples per game, with up to 9 injuries per game. The multivariate analysis identified significant associations between game duration and injuries per game (P < .001; effect size, 0.013) and the level of play and injuries per game (P < .001; effect size, 0.011). There were significant associations between the venue type (P < .001), the game start time (P < .001), humidity (P < .001), the turf type (P = .016), and barometric pressure (P = .031); however, the effect size for each was <0.001, suggesting that these factors are clinically unimportant. Our overall model produced an R2 of 0.04, indicating that these variables only predicted 4% of the variance in injury risk. CONCLUSION In professional baseball, the weather is not associated with injury risk; however, game duration may contribute to injury risk.

Abstract
BACKGROUND Meniscal injuries are common in athletes across many sports. How professional baseball players respond to partial meniscectomy is not well documented. PURPOSE/HYPOTHESIS The purpose was to determine the performance and return-to-sports (RTS) rate in professional baseball players after arthroscopic partial knee meniscectomy and compare the results of partial medial meniscectomy versus partial lateral meniscectomy. The hypothesis was that there would be a high RTS rate in professional baseball players after partial meniscectomy with no difference in the RTS rate or timing of RTS between players who underwent partial medial meniscectomy versus partial lateral meniscectomy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All professional baseball players who underwent arthroscopic partial meniscectomy between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Demographic and performance data (before and after injury) for each player were recorded. The RTS rate and timing of RTS were then compared between players who underwent partial medial meniscectomy versus partial lateral meniscectomy. RESULTS A total of 168 knees (168 players) underwent arthroscopic partial meniscectomy (mean age, 25 ± 5 years; 46% medial meniscectomy, 45% lateral meniscectomy, and 9% both medial and lateral meniscectomy). The most common mechanism of injury was fielding in the infield on natural grass. Injuries were spread evenly across positions: 18% catchers, 24% infielders, 20% outfielders, and 38% pitchers. The overall RTS rate was 80% (76% returned to the same or a higher level, and 4% returned to a lower level). For performance, pitchers saw significant decreases in usage but significant improvements in performance using the advanced statistics of fielding independent pitching (P < .001) and wins above replacement (P = .011). Hitters saw significant decreases in usage but increases in efficiency as seen by improvements in wins above replacement (P = .003). Of the 79 athletes who returned during the same season, the median time to return to play was 42 days. CONCLUSION The RTS rate after meniscectomy in professional baseball players was 80%. Player efficiency improved after surgery in pitchers and position players. No difference in the RTS rate or timing of RTS existed between players who underwent partial medial meniscectomy versus partial lateral meniscectomy.
