Return-to-Play Rates and Clinical Outcomes of Baseball Players After Concomitant Ulnar Collateral Ligament Reconstruction and Selective Ulnar Nerve Transposition.

Background: Injury to the ulnar collateral ligament (UCL) leading to medial elbow instability and possible ulnar neuritis is common in overhead-throwing athletes. Treatment may require UCL reconstruction (UCLR) and concomitant ulnar nerve transposition (UNT) for those with preoperative ulnar neuritis. Purpose: To evaluate the return-to-play (RTP) rates, clinical outcomes, and rates of persistent ulnar neuritis after concomitant UCLR and UNT in a cohort of baseball players with confirmed preoperative ulnar neuritis. Study Design: Case series; Level of evidence, 4. Methods: Eligible patients were those who underwent concomitant UCLR and UNT at a single institution between January 2008 and June 2018 and who had a minimum of 2 years of follow-up. Additional inclusion criteria were athletes who identified as baseball players and who had a confirmed history of ulnar neuritis. Patients were contacted at a minimum of 2 years from surgery and assessed with the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score, Andrew-Timmerman (A-T) Elbow Score, Mayo Elbow Performance Score (MEPS), Single Assessment Numeric Evaluation (SANE) score, and a custom RTP questionnaire. Results: Included were 22 male baseball players with a mean age of 18.9 ± 2.1 years (range, 16-25 years). The mean follow-up was 6.1 ± 2.4 years (range, 2.5-11.7 years). Preoperatively, all 22 patients reported ulnar nerve sensory symptoms, while 4 (18.2%) patients reported ulnar nerve motor symptoms. At the final follow-up, 7 (31.8%) patients reported persistent ulnar nerve sensory symptoms, while none of the patients reported persistent ulnar nerve motor symptoms. Overall, 16 (72.7%) players were able to return to competitive play at an average of 11.2 months. The mean postoperative patient-reported outcome scores for the KJOC Shoulder and Elbow Score, MEPS, A-T Elbow Score, and SANE score were 77.9 ± 20.9 (range, 14-100), 92.7 ± 12.7 (range, 45-100), 86.1 ± 17.1 (range, 30-100), and 85.5 ± 14.8 (range, 50-100), respectively. Conclusion: This study demonstrated that after concomitant UCLR and UNT for UCL insufficiency and associated ulnar neuritis, baseball players can expect reasonably high RTP rates and subjective outcomes; however, rates of persistent sensory ulnar neuritis can be as high as 30%

Surgical Techniques and Clinical Outcomes for Medial Epicondylitis: A Systematic Review.

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 \u3c90%. 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
