Current Concepts in the Business of Orthopaedics.

Practice management within orthopaedic surgery demands a multifaceted skillset including clinical expertise, technical proficiency, and business acumen, yet the latter is rarely taught during orthopaedic training. As the healthcare system evolves in the United States, surgeons continue to face challenges such as decreasing reimbursements, increased regulatory burdens, and potential for practice acquisition. To remain competitive and provide exceptional care for patients, orthopaedic surgeons must cultivate a business-minded approach. This article highlights the growing significance of the business of orthopaedics and offers guidance on ambulatory surgical center ownership models, effective management of ancillary services, the effect of private equity in orthopaedic practice, real estate investment opportunities in medical office buildings, and the importance of brand recognition. By understanding these concepts, orthopaedic surgeons can exercise greater control over their practice's finances while providing quality care for their patients.

Return to Sport After Arthroscopic Capsular Repair in Elite Baseball Players.

Background: Chronic attritional midsubstance capsular tears arising from repetitive throwing stress are a rare but important source of pain and dysfunction in elite baseball players; however, little is known regarding outcomes after arthroscopic capsular repair. Purpose: To evaluate the patient-reported outcomes and return-to-sport (RTS) rates after arthroscopic capsular repair in elite baseball players. Study Design: Case series; Level of evidence, 4. Methods: We identified 11 elite-level baseball players who were treated with arthroscopic repair for a midsubstance glenohumeral capsular tear by a single surgeon with a uniform approach and a standardized postoperative protocol between 2012 and 2019. All players had at least 2 years of follow-up data. Demographic data and concomitant surgical procedures were recorded. Preoperative and postoperative Kerlan-Jobe Orthopaedic Clinic (KJOC) scores and Single Assessment Numeric Evaluation (SANE) scores were collected in a subset of the cohort, and statistical comparisons were made. A telephone survey was conducted to determine the patients' RTS level and outcome scores. Statistical comparisons between preoperative and postoperative outcomes scores were made using t tests. Results: Eight major league players, 1 minor league player, and 2 collegiate players were included. There were 9 pitchers, 1 catcher, and 1 outfielder. All patients had debridement of the posterosuperior labrum and rotator cuff. Two pitchers underwent a rotator cuff repair, and 1 outfielder underwent a posterior labral repair. The mean age at the time of surgery was 26.9 years (range, 20-34 years), with a mean follow-up of 3.5 years (range, 2.6-5.9 years). There were significant preoperative versus postoperative improvements in the mean KJOC (20.6 vs 89.8; P = .0002) and SANE (28.3 vs 86.7; P = .001) scores. All patients reported a high degree of satisfaction. At a mean of 16.3 months (range, 6.5-25.4 months), 10 of 11 (90.1%) players met the Conway-Jobe good or excellent criteria for RTS. Conclusion: Arthroscopic capsular repair provided significant improvements in functional outcomes in elite baseball players, high levels of patient satisfaction, and high levels of RTS.

The Use of Biologics in NFL Athletes: An Expert Consensus of NFL Team Physicians.

Background: There is a lack of published information outlining the use of biologics in National Football League (NFL) athletes and limited data to guide biologic treatment strategies. Purpose: To develop a consensus on the use of biologics among NFL team physicians. Study Design: Consensus statement. Methods: A working group of 6 experts convened a consensus process involving NFL team physicians using validated Delphi methodology. Physicians from 32 NFL teams as well as NFL London were invited to take part. This iterative process was used to define statements on the use of biologics in NFL athletes. A recent scoping review exploring biologics in professional athletes was used to inform the first of 3 rounds of surveys, with statements considered under 7 headings: biologics in general, challenges of treating NFL athletes, terminology/nomenclature, autologous blood products, cell-based therapies, guidance for NFL team physicians, and biologic research in the NFL. In addition to rating agreement, experts were encouraged to propose further items or modifications. Predefined criteria were used to refine item lists after each survey. For a consensus within the final round, defined a priori, items were included in the final information set if a minimum of 75% of respondents agreed and fewer than 10% disagreed. Results: Physicians from 26 NFL teams and NFL London responded to the initial invitation to participate in the Delphi process; 88.9% of participating team physicians completed the round 1 survey, with response rates of 87.5% in round 2 and 95.2% in round 3. After 3 rounds, 47 statements reached a consensus. A consensus was achieved that platelet-rich plasma has a positive impact on patellar tendinopathy and on symptoms in early osteoarthritis but not for other indications. NFL team physicians agreed that while cell therapies have the potential to improve symptoms, the misrepresentation of uncharacterized preparations as "stem cells" has contributed to the widespread use of unproven therapies. Conclusion: This study established an expert consensus on 47 statements relating to the use of biologics in NFL athletes. In addition to providing clinical guidance for the use of biologics in NFL athletes, this study identified key areas for future focus including the development of athlete education materials.

Prevalence of femoroacetabular impingement in elite baseball players.

CAM-type femoroacetabular impingement continues to be an underrecognized cause of hip pain in elite athletes. Properties inherent to baseball such as throwing mechanics and hitting may enhance the risk of developing a cam deformity. Our goal is to gain an appreciation of the radiographic prevalence of cam deformities in elite baseball players. Prospective evaluation and radiographs of 80 elite baseball players were obtained during the 2016 preseason entrance examination. A sports medicine fellowship-trained orthopedic surgeon with experience treating hip disorders used standard radiographic measurements to assess for the radiographic presence of cam impingement. Radiographs with an alpha angle >55° on modified Dunn views were defined as cam positive. Of the 122 elite baseball players included in our analysis, 80 completed radiographic evaluation. Only 7.3% (9/122) of players reported hip pain and 1.6% (4/244) had a positive anterior impingement test. The prevalence of cam deformities in right and left hips were 54/80 (67.5%) and 40/80 (50.0%), respectively. The mean alpha angle for cam-positive right and left hips were 64.7 ± 6.9° and 64.9 ± 5.8°, respectively. Outfielders had the highest risk of right-sided cam morphology (Relative Risk (RR) = 1.6). Right hip cam deformities were significantly higher in right-handed pitchers compared with left-handed pitchers (P = 0.02); however, there was no significant difference in left hip cam deformities between left- and right-handed pitchers (P = 0.307). Our data suggest that elite baseball players have a significantly higher prevalence of radiographic cam impingement than the general population.

Outcomes After Medial Ulnar Collateral Ligament Graft Repair in Professional Baseball Pitchers With Minimum 2-Year Follow-up.

Background: Rerupture of the reconstructed ulnar collateral ligament (UCL) is becoming more frequent at the professional level of baseball. However, there is no literature describing outcomes after UCL graft repair. Purpose: To evaluate rerupture rate, return to play, performance upon return, and patient-reported outcomes after a novel UCL graft repair technique. Study Design: Case series; Level of evidence, 4. Methods: All included patients underwent UCL graft repair after a previous UCL reconstruction, pitched in at least 1 professional baseball game before repair, and were at least 2 years postprocedure within the same 10-year time period. The authors evaluated patient characteristics and performance metrics, including wins, losses, win percentage, earned run average, innings pitched, walks and hits per inning pitched, for the 2 seasons before and after the procedure. Patients were contacted to assess UCL rerupture, timing of return to sport, current level of competition, Conway score, and Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score. Results: Six players met the inclusion criteria. All had proximal UCL graft ruptures and underwent flexor-pronator tendon repair in combination with graft repair. At a mean (±SD) follow-up of 56.7 ± 37.8 months, no reruptures were encountered, and the mean KJOC score was 87.9 ± 14.6. Of the 6 pitchers who underwent UCL graft repair, 4 (67%) returned to professional pitching at a mean of 17 ± 6 months. Three of the 6 (50%) achieved an excellent Conway score, signifying a return to prior level of sport. There was no significant difference in demographic or preoperative pitching performance metrics between players who did and did not return to pitching. For those players who returned to professional pitching, there was no significant difference between preprocedure and postprocedure performance statistics. Conclusion: Repair of the UCL graft appears to yield comparable rates of return to play and performance with revision UCL reconstruction. This technique serves as a viable alternative for proximal avulsion ruptures of the UCL graft.

Return to play after ulnar collateral ligament reconstruction with concurrent posterior-compartment decompression.

BACKGROUND: Medial ulnar collateral ligament (UCL) injuries and posterior elbow impingement commonly affect throwing athletes. Surgical intervention for each of these pathologies individually has been demonstrated to be successful with high return-to-play (RTP) rates. Our purpose was to report RTP rates for patients treated with concurrent UCL reconstruction (UCLR) and arthroscopic posterior débridement performed by the senior author. MATERIALS AND METHODS: We retrospectively reviewed all elbow medial UCL procedures performed by the senior author from January 2016 through September 2020. The inclusion criteria included an elbow medial UCL operation with arthroscopic posterior-compartment débridement in a throwing athlete. The exclusion criteria included isolated UCLR surgery, non-primary surgery, and revision UCLR with either autograft or allograft. Using a chart review and publicly available information, we were able to determine patients' playing levels after their operations. RESULTS: Twelve patients met the inclusion and exclusion criteria. The average age was 24.27 years (standard deviation, 4.92 years). Of the 12 patients, 10 returned to play at the same level (4 Major League Baseball players and 1 Triple A player) or at a higher level (2 players from Single A to Double A, 1 player from National Collegiate Athletic Association Division I to Single A, 1 player from rookie league to Single A, and 1 player from high school to National Collegiate Athletic Association Division I), 1 did not return to play, and 1 returned to play at a lower level, with an average RTP time of 14.64 months (standard deviation, 2.64 months). Of the 12 patients, 11 were pitchers; of these 11 pitchers, 9 had statistics available both before and after UCLR. Before UCLR, the average statistics for the pitchers were as follows: earned run average, 4.11 ± 0.85; walks and hits per inning pitched, 1.42 ± 0.26; strikeout-to-walk ratio, 3.00 ± 1.83; strikeouts per 9 innings, 8.80 ± 1.14; and innings pitched, 234.88 ± 316.74. After UCLR, their average statistics were as follows: earned run average, 5.24 ± 2.18 (P = .189); walks and hits per inning pitched, 1.55 ± 0.34 (P = .379); strikeout-to-walk ratio, 2.15 ± 0.98 (P = .263); strikeouts per 9 innings, 9.67 ± 1.91 (P = .293); and innings pitched, 138.71 ± 162.97 (P = .487). DISCUSSION AND CONCLUSION: Although surgical intervention to address both posterior impingement and UCL injury is relatively rare (comprising 8.5% of all the senior author's UCLR procedures), our experience demonstrates that primary UCLR with concurrent arthroscopic posterior decompression is a reliable, safe, and successful surgical treatment for patients with UCL injury and posterior impingement and our results show no significant difference in statistical performance in pitchers before surgery vs. after surgery.

Ulnar Neuritis and Its Affect on Outcomes of Elbow Ulnar Collateral Ligament Reconstruction.

BACKGROUND: No study has specifically evaluated how ulnar neuritis and ulnar nerve transposition affect outcomes in baseball players undergoing ulnar collateral ligament (UCL) reconstruction (UCLR). PURPOSE: To evaluate the effects of ulnar neuritis and ulnar nerve transposition in baseball pitchers undergoing UCLR in regard to return to sport, time to return to sport, and need for revision or additional surgery. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: At a single institution, all consecutive baseball pitchers undergoing UCLR between 2002 and 2015 were identified. Ulnar neuritis was diagnosed preoperatively by the following criteria: ulnar nerve symptoms, Tinel sign at the elbow, symptomatic subluxation, and numbness/paresthesia in an ulnar nerve distribution of the hand. The primary outcome of the study was return to sport. The secondary outcomes of the study were time to return to sport, length of playing career, and revision or additional surgery. RESULTS: A total of 578 UCLRs were performed in baseball players; of these, 500 UCLRs were performed in pitchers. Ulnar neuritis was diagnosed in 97 (19.4%) baseball pitchers presenting with UCL injury. There were no significant differences in patient characteristics or surgical techniques performed for reconstruction between baseball pitchers with and without ulnar neuritis. In review of injury characteristics, ulnar neuritis was significantly more likely to be diagnosed in pitchers with an acute onset of UCL injury (P = .03). Transposition of the ulnar nerve was more commonly performed in players with ulnar neuritis (47%) versus those without ulnar neuritis (10%; P = .0001). The players who had ulnar neuritis and underwent UCLR had a significantly lower odds of returning to sport (odds ratio, 0.45; P = .04); however, no significant difference was found for time to return to sport and length of playing career for those with and without ulnar neuritis (P = .38 and .51, respectively). CONCLUSION: The study suggests that ulnar neuritis, when present preoperatively in baseball pitchers undergoing UCLR, may adversely affect their ability to return to sport, whereas ulnar nerve transposition at the time of UCLR does not alter the ability to return to sport.

Posterior Lateral Meniscal Root Tears Increase Strain on the Reconstructed Anterior Cruciate Ligament: A Cadaveric Study.

PURPOSE: To quantify the amount of strain across an anterior cruciate ligament reconstruction (ACLR) before and after a lateral meniscus (LM) posterior root complex tear and determine whether a meniscal root repair effectively protects the ACLR against excessive strain. METHODS: Fresh-frozen cadaveric knees were tested with an 88-N anterior drawer force and an internal and external torque of 5-Nm applied at 0°, 15°, 30°, 60°, and 90° of flexion. A simulated pivot shift was also applied at 0, 15, and 30° of flexion. Rotation and translation of the tibia, and strain across the ACL graft were recorded. Testing was repeated for the following four conditions: ACL-intact, ACLR with intact LM, ACLR with LM posterior root complex tear, and ACLR with root repair. RESULTS: The kinematic data from 12 fresh frozen cadaveric knees underwent analysis. Only 11 specimens had usable strain data. Sectioning the meniscofemoral ligaments and the LM posterior root increased rotational and translational laxity at 30° of knee flexion. ACLR graft strain significantly increased when an anterior load and internal torque were applied. Repair of the LM posterior root reduced strain when the knee was internally rotated but was unable to normalize strain when an anterior force was applied. CONCLUSIONS: This cadaveric biomechanical study suggests injury to the LM posterior root complex increases rotational and anterior laxity of the knee and places increased strain across reconstructed ACL grafts. Subsequent root repair did not result in a statistically significant reduction in strain. CLINICAL RELEVANCE: This study provides quantitative data on the implications of a LM posterior root injury in the setting of an ACL reconstruction to help guide clinical decision-making.

Anterior cruciate ligament reconstruction femoral tunnel drilling preference among orthopaedic surgeons.

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) technique for femoral tunnel drilling varies substantially, each with advantages and disadvantages. The purpose of this study was to define ACLR femoral tunnel technique predilection among surgeons and to explore factors associated with their preference. METHODS: An 11-question survey regarding ACLR femoral tunnel technique was completed by 560 AANA/AOSSM members. Surgeon and practice demographics and residency and fellowship experiences were evaluated with bivariate and multivariable models for association with surgeon preference. RESULTS: In current practice, 55% of surgeons prefer anteromedial (AM) portal drilling, 32% retrograde, and 14% transtibial (TT). Sports Medicine fellowship experience was the strongest predictor of current practice (p < 0.001), followed by residency technique (p = 0.014). A significant increase in TT drilling was noted for those practicing >15 years TT (29% vs 3%, p < 0.001), with an inverse relationship for retrograde drilling (38% vs 21%, p < 0.001). Number of ACLRs/year and percent Sports specific practice were significant predictors for AM drilling (p < 0.001). Though less than AM and retrograde, TT was more common for those in private practice (17% vs 8%, p < 0.001), and more prevalent in the Midwest/Southeast (19% vs 10%, p = 0.003). Non-significant predictors included highest level of athlete for whom an ACLR had been performed, level of athlete serving as team physician, and Certificate of Added Qualifications status. CONCLUSION: Surgeon training, practice setting, and years in practice significantly predict preference for femoral tunnel drilling technique. Surgeon comfort and confidence in attaining an anatomic reconstruction should drive choice of technique.

Anterior Cruciate Ligament Reconstruction Graft Preference Most Dependent on Patient Age: A Survey of United States Surgeons.

PURPOSE: The purpose of this study was to define the anterior cruciate ligament (ACL) reconstruction (ACLR) graft preference of surgeons and to explore factors associated with their predilection. METHODS: A 15-question survey regarding ACLR graft preference in various situations was completed by 514 American Orthopaedic Society for Sports Medicine and Arthroscopy Association of North America surgeons. Surgeon and practice demographics, along with various patient factors, were evaluated with bivariate and multivariable models for association with surgeon preference. Surgeons were also queried about their preference for their own ACLR. For surgeons who personally sustained an ACL, an additional 6 questions inquired about their experience. RESULTS: Surgeons reported the 5 most important factors in patient graft choice, in order: patient age, graft failure in literature and practice, pivot sport, and patient preference. Autograft patellar and quadriceps tendon were strongly preferred for younger, pivoting athletes (P < .001), among those with fellowship training (47% vs 33%, P = .006), in academic practices (52% vs 44%, P = .003), and in more sports medicine-specific practices, with a higher number of ACLRs performed per year (P < .001). Northeast, Southeast, Midwest, and Southwest surgeons had lower hamstring autograft preference (P < .001). Non-fellowship-trained surgeons preferred hamstring autograft (P = .010). Allograft was preferred for older patients (P < .001). Nonsignificant predictors included highest level of athlete for whom an ACLR had been performed, level of athlete serving as team physician, and years in practice. No factors were associated with surgeon preference for their own ACLR despite deeming these factors important for patients. ACL tears were reported by 13% of respondents, with 86% stating it influenced their decision to enter orthopaedics. CONCLUSIONS: Patient age was the most important factor in graft choice, with patellar and quadriceps tendon autograft the preferred graft for ACLR for younger, pivoting athletes. Fellowship training and practice demographics were also correlated with graft choice for patients. CLINICAL RELEVANCE: Graft preference for ACLR varies among surgeons and is associated with surgeon experience and patient characteristics, including patient age, type of sport, and patient preference.

Biomechanical Comparison of UCL Repair Using Suspensory Fixation Versus UCL Reconstruction.

BACKGROUND: Medial ulnar collateral ligament (mUCL) repair is growing in popularity as a treatment for younger athletes with mUCL tears. One of the most recent techniques utilizes a collagen-coated suture tape to augment the repair. The most popular repair technique uses a screw for proximal fixation in the humerus. We present an alternative technique that uses suspensory fixation in the proximal humerus. PURPOSE: To biomechanically compare elbow valgus stability and load to failure of a novel alternative repair technique with suspensory fixation to an mUCL reconstruction. STUDY DESIGN: Controlled laboratory study. METHODS: Eighteen fresh-frozen cadaveric elbows were dissected to expose the mUCL. Medial elbow stability was tested with the mUCL in an intact, deficient-either repaired or reconstructed-state. The repair technique used a suspensory fixation with suture augmentation, and the docking technique was used on all reconstructions. A 3-N·m valgus torque was applied to the elbow, and valgus rotation of the ulna was recorded via motion tracking cameras as the elbow was cycled through a full range of motion. After kinematic testing, specimens were loaded to failure at 70° of elbow flexion. RESULTS: Both ulnar collateral ligament reconstruction and repair restored valgus stability to levels that were not statistically different from intact at all angles of flexion. There was no significant difference in the ultimate torque to failure between repaired and reconstructed mUCLs. CONCLUSION: There was no significant difference in the valgus strength between the mUCL repair with suspensory fixation and the mUCL reconstruction. CLINICAL RELEVANCE: Suspensory fixation is an alternative method for proximal fixation in the mUCL without compromising the strength of the construct.

Decision making in treatment after a first-time anterior glenohumeral dislocation: A Delphi approach by the Neer Circle of the American Shoulder and Elbow Surgeons.

BACKGROUND: The treatment of patients who sustain a first-time anterior glenohumeral dislocation (FTAGD) is controversial. The purpose of this study was to find consensus among experts using a validated iterative process in the treatment of patients after an FTAGD. METHODS: The Neer Circle is an organization of shoulder experts recognized for their service to the American Shoulder and Elbow Surgeons. Consensus among 72 identified experts from this group was sought with a series of surveys using the Delphi process. The first survey used open-ended questions designed to identify patient-related features that influence treatment decisions after an FTAGD. The second survey used a Likert scale to rank each feature's impact on treatment decisions. The third survey used highly impactful features to construct 162 clinical scenarios. For each scenario, experts recommended surgery or not and reported how strongly they made their recommendation. These data were analyzed to find clinical scenarios that had >90% consensus for recommending treatment. These data were also used in univariate and multivariate mixed-effects models to identify odds ratios (ORs) for different features and to assess how combining these features influenced the probability of surgery for specific populations. RESULTS: Of the 162 scenarios, 8 (5%) achieved >90% consensus for recommending surgery. All of these scenarios treated athletes with meaningful bone loss at the end of their season. In particular, for contact athletes aged > 14 years who were at the end of the season and had apprehension and meaningful bone loss, there was >90% consensus for recommending surgery after an FTAGD, with surgeons feeling very strongly about this recommendation. Of the scenarios, 22 (14%) reached >90% consensus for recommending nonoperative treatment. All of these scenarios lacked meaningful bone loss. In particular, surgeons felt very strongly about recommending nonoperative treatment after an FTAGD for non-athletes lacking apprehension without meaningful bone loss. The presence of meaningful bone loss (OR, 6.85; 95% confidence interval, 6.24-7.52) and apprehension (OR, 5.60; 95% confidence interval, 5.03-6.25) were the strongest predictors of surgery. When these 2 features were combined, profound effects increasing the probability of surgery for different populations (active-duty military, non-athletes, noncontact athletes, and contact athletes) were noted, particularly non-athletes. CONCLUSION: Consensus for recommending treatment of the FTAGD patient was not easily achieved. Certain combinations of patient-specific factors, such as the presence of meaningful bone loss and apprehension, increased the probability of surgery after an FTAGD in all populations. Over 90% of shoulder instability experts recommend surgery after an FTAGD for contact athletes aged > 14 years at the end of the season with both apprehension and meaningful bone loss. Over 90% of experts would not perform surgery after a first dislocation in patients who are not athletes and who lack apprehension without meaningful bone loss.

Biomechanical Evaluation of a Modified Internal Brace Construct for the Treatment of Ulnar Collateral Ligament Injuries.

BACKGROUND: Ulnar collateral ligament (UCL) repair augmented with the "internal brace" construct for the management of acute UCL injuries has recently garnered increasing interest from the sports medicine community. One concern with this technique is excessive bone loss at the sublime tubercle, should revision UCL reconstruction be required. In an effort to preserve the bony architecture of the sublime tubercle, an alternative internal brace construct is proposed and biomechanically compared with the gold standard UCL reconstruction. HYPOTHESIS: The internal brace repair construct will restore valgus laxity and rotation to its native state and demonstrate comparable load-to-failure characteristics with the 3-strand reconstruction technique. STUDY DESIGN: Controlled laboratory study. METHODS: For this study, 8 matched pairs of fresh-frozen cadaveric elbows were randomized to undergo either UCL reconstruction with the 3-ply docking technique or UCL repair with a novel internal brace construct focused on augmenting the posterior band of the anterior bundle of the ligament (modified repair-IB technique). Valgus laxity and rotation measurements were quantified through use of a MicroScribe 3DLX digitizer at various flexion angles of the native ligament, transected ligament, and repaired or reconstructed ligament. Laxity testing was performed from maximum extension to 120° of flexion. Each specimen was then loaded to failure, and the method of failure was recorded. RESULTS: Valgus laxity was restored to the intact state at all degrees of elbow flexion with the modified repair-IB technique, and rotation was restored to the intact state at both full extension and 30°. In the reconstruction group, valgus laxity was not restored to the intact state at either full extension or 30° of flexion (P < .001 and P = .004, respectively). Laxity was restored at 60° of flexion, but the elbow was overconstrained at 90° and 120° of flexion (P = .027 and P = .003, respectively). In load-to-failure testing, the reconstruction group demonstrated significantly greater yield torque (19.1 vs 9.0 N·m; P < .005), yield angle (10.2° vs 5.4°; P = .007), and ultimate torque (23.9 vs 17.6 N·m; P = .039). CONCLUSION: UCL repair with posterior band internal bracing was able to restore valgus laxity and rotation to the native state. The construct exhibited lower load-to-failure characteristics when compared with the reconstruction technique. CLINICAL RELEVANCE: In selected patients with acute, avulsion-type UCL injuries, ligament repair with posterior band internal bracing is a viable alternative surgical option that, by preserving bone at the sublime tubercle, may decrease the complexity of future revision procedures.

Major League Baseball Pitching Performance After Tommy John Surgery and the Effect of Tear Characteristics, Technique, and Graft Type.

BACKGROUND: Return to play and player satisfaction have been quite high after ulnar collateral ligament reconstruction (UCLR); however, there has been little reported on how outcomes are affected by surgical technique, graft type, and tear characteristics. PURPOSE: To evaluate surgical techniques, graft type, and tear characteristics on Major League Baseball (MLB) performance after UCLR. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: MLB pitchers who underwent primary UCLR at a single institution were included. Tear characteristics included tear location, tear grade, and acuity. Surgical technique and graft type were also collected. Pitching performance statistics, including earned run average (ERA), walks and hits per innings pitched (WHIP), innings pitched, and fastball velocity were evaluated 3 years before and after UCLR. RESULTS: Forty-six MLB pitchers were identified as having primary UCLR. Return to play was 96%, with 82% returning to MLB play. Technique performed showed no difference in performance. As compared with pitchers with gracilis grafts, pitchers with palmaris grafts were younger ( P = .043), played longer after surgery ( P = .012), and returned to play at 100% (35 of 35) versus 82% (9 of 11, P = .010). When compared with pitchers with proximal tears, pitchers with distal tears pitched at higher velocity (93.0 vs 90.6 mph, P = .023) and had better performance before surgery (ERA, P = .003; WHIP, P = .021); however, those with proximal tears improved to match this performance and velocity after reconstruction. As compared with those having partial tears, pitchers with complete tears played longer after surgery (5.9 vs 4.0 years, P = .033), had a better ERA before injury ( P = .041), and had better WHIP ( P = .037) and strikeouts per 9 innings ( P = .025) after reconstruction. Pitchers with chronic tears had a significant improvement in postoperative ERA, from 4.49 to 3.80 ( P = .040). CONCLUSION: Technique performed and graft type used did not affect performance; however, pitchers with palmaris grafts returned at a higher rate than those with gracilis grafts. Distal tears occurred in pitchers with greater velocity and better performance before injury, yet pitchers with proximal tears matched this performance after reconstruction. Pitchers with complete tears played longer after reconstruction. Pitchers who had partial tears had worse performance before injury and after reconstruction, and those with chronic tears saw a significant improvement in ERA with reconstruction.

Hamstring Injuries in Major League Baseball Pitchers: Implications in Graft Selection for Ulnar Collateral Ligament Reconstruction.

BACKGROUND: Hamstring tendons are commonly harvested as autograft for ulnar collateral ligament reconstruction. There is no consensus in the literature whether the hamstring tendon should be harvested from the ipsilateral (drive) leg or contralateral (landing) leg of baseball pitchers undergoing ulnar collateral ligament reconstruction. Hamstring injuries commonly occur in baseball players, but there are no reports on their incidence specifically among Major League Baseball (MLB) pitchers, nor are there reports on whether they occur more commonly in the drive leg or the landing leg. HYPOTHESIS: Hamstring injuries occur more commonly in the landing legs of MLB pitchers. STUDY DESIGN: Descriptive epidemiology study. METHODS: MLB pitchers who sustained hamstring injuries requiring time spent on the disabled list were identified from publicly available sources over 10 seasons. Demographics of the pitchers and injury and return-to-sport data were collected. Hamstring injuries to the drive leg were compared with injuries to the landing leg. RESULTS: Sixty-five pitchers had 78 disabled list stints due to hamstring injuries over 10 seasons. The landing leg was injured in 67.9% of cases, and the most common mechanism of injury was pitching. There were no significant differences in demographics between pitchers who sustained drive leg and landing leg injuries. There was no significant difference in mechanism of injury or time to return to sport between pitchers who sustained drive leg and landing leg injuries. CONCLUSION: The landing leg is more commonly injured than the drive leg among MLB pitchers who sustain hamstring injuries. There is no difference in time to return to sport between pitchers who sustain drive leg and landing leg injuries. More research is required to determine whether there is a difference in performance or future injury between hamstring tendons harvested from the drive leg and the landing leg for ulnar collateral ligament reconstruction among pitchers.

Medial Elbow Pain During the Return-to-Throwing Period After Ulnar Collateral Ligament Reconstruction in Pitchers.

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) is common in the sport of baseball, particularly among pitchers. Postoperative return-to-sport protocols have many players beginning to throw at 4 to 5 months and returning to full competition between 12 and 16 months after surgery. Medial elbow pain during the return-to-throwing period often occurs and can be difficult to manage. PURPOSE: To evaluate the incidence of medial elbow pain and associations with outcomes and revision surgery during the return-to-throwing period after UCLR. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Between the years of 2002 and 2014, all pitchers who underwent UCLR at a single institution were identified. Charts were reviewed for incidence of medial elbow pain during return to throwing, return to sport, and subsequent operative interventions, including revision ulnar collateral ligament surgery. RESULTS: Of a total of 616 pitchers who underwent UCLR during the study period, 317 were included in this study. Medial elbow pain was experienced by 45.1% (143 of 317), with a mean time of complaint of 9.75 months after surgery. The groups with and without pain did not differ statistically with regard to age (pain, 20.6 years; no pain, 20.9 years) or level of competition. Of those who experienced medial elbow pain, 10.5% did not return to sport; 5.6% underwent revision UCLR; and 19.6% underwent other operative procedures at the elbow. Among those who did not experience medial elbow pain when returning to throw, 8.7% did not return to sport, with only 1.7% undergoing revision UCLR and 6.9% undergoing other operative elbow procedures. CONCLUSION: Of the pitchers evaluated in the study, approximately half reported pain during the return-to-throwing phase after UCLR. Those who experienced medial elbow pain had a higher rate of subsequent surgical intervention.

Pitching Performance After Ulnar Collateral Ligament Reconstruction at a Single Institution in Major League Baseball Pitchers.

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