While numerous studies exist evaluating the short-term clinical outcomes for patients who have undergone elbow arthroscopy for osteochondritis dissecans (OCD) of the capitellum, the literature on minimum 2-year clinical outcomes for a large cohort of patients is limited. /Hypothesis: We hypothesized that clinical outcomes for patients treated arthroscopically for OCD of the capitellum would be favorable, with improved postoperative subjective functional and pain scores, and with acceptable return to play for these patients. A retrospective analysis from a prospectively collected surgical database was performed to identify all patients treated surgically for OCD of the capitellum at our institution from January 2001 to August 2018. Inclusion criteria for this study included the diagnosis of OCD of the capitellum treated arthroscopically with minimum 2-year follow-up. Exclusion criteria included any prior surgical treatment on the ipsilateral elbow, missing operative reports, and patients with any portions of the surgical procedure performed open. Follow-up was performed by telephone using multiple patient-reported outcome questionnaires: American Shoulder and Elbow Surgeons - Elbow (ASES-e), Andrews/Carson, Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score (KJOC), and our institution-specific return-to-play questionnaire. After the inclusion and exclusion criteria were applied to our surgical database, 107 eligible patients were identified. Of these, 90 were successfully contacted for a follow-up rate of 84%. The mean age was 15.2 years and mean follow-up time was 8.3 years. Eleven patients had a subsequent revision procedure for a 12% failure rate in these patients. ASES-e pain was an average of 4.0 out of a max pain scale of 100, ASES-e function was an average of 34.5 out of a maximum of 36, and surgical satisfaction was an average of 9.1 out of 10. The average Andrews/Carson score was 87.1 out of 100 and the average KJOC score for overhead athletes was 83.5 out of 100. Additionally, out of the 87 patients evaluated who played sports at the time of their arthroscopy, 81 (93%) returned to play. This study demonstrated an excellent return-to-play rate and satisfactory subjective questionnaire scores with a 12% failure rate following arthroscopy for OCD of the capitellum with a minimum 2-year follow-up.
