Broughton JS, Goldfarb CA, Obey MR, et al. - This study was undertaken to investigate patient long term outcomes applying Patient-Reported Outcomes Measurement Information System (PROMIS) scores, compare the performance of PROMIS to other validated elbow legacy metrics, and assess ceiling and floor effects in these outcome measures in patients undergoing surgical treatment for capitellar osteochondritis dissecans (OCD). In this study, demographics, procedure details, preoperative PROMIS scores, and associated sports information surgically treated pediatric capitellar OCD patients were examined. Researchers collected completed surveys for 57 patients (59 elbows). The mean patient age at surgery was 14 years (range 10-18). The mean follow-up time was 6 years (SD=5, range 1-18). A strong relationship was found between PROMIS scores and legacy measures assessing outcomes after surgical management of capitellar OCD. Nevertheless, large ceiling and floor impacts were present in all measures, likely due to the favorable clinical results. It was shown that the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score score was limited the least by the ceiling/floor effect.
