Abstract

Background: Patient-Reported Outcomes Measurement Information System (PROMIS) scores have not previously been used to measure long-term outcomes in operatively treated capitellar osteochondritis dissecans (OCD) patients. The aims of our study were to (1) assess patients’ long-term outcomes using PROMIS scores, (2) compare the performance of PROMIS with other validated elbow legacy metrics, and (3) evaluate ceiling and floor effects in these outcome measures in patients undergoing surgical treatment for capitellar OCD. Methods: We evaluated demographic characteristics, procedure details, preoperative PROMIS scores, and associated sports information in surgically treated pediatric capitellar OCD patients. An online survey was sent to the study participants, including the Kerlan-Jobe Orthopaedic Clinic (KJOC) shoulder and elbow score, the quick Disabilities of the Arm, Shoulder and Hand questionnaire, and the Liverpool Elbow Score patient-answered questionnaire, as well as the Mobility, Pain Interference, and Upper Extremity questionnaires from the PROMIS pediatrics bank. Correlations were evaluated between outcome measures. Ceiling and floor effects were evaluated for each outcome measure. Results: Completed surveys were obtained for 57 patients (59 elbows). The mean patient age at surgery was 14 years (range, 10-18 years). The mean follow-up time was 6 years (standard deviation, 5 years; range, 1-18 years). The mean PROMIS Mobility score improved from 41.2 preoperatively to 55.2 postoperatively (P <.001). The mean Pain Interference score decreased from 46.9 preoperatively to 38 postoperatively (P <.001). The mean Upper Extremity score improved from 42.7 preoperatively to 53.2 postoperatively (P <.001). Significant correlations were observed between all legacy metrics and postoperative PROMIS scores (|r| > 0.54, P <.001). Ceiling or floor effects were seen in all legacy metrics and PROMIS scores. The KJOC score was least affected by ceiling or floor effects. Conclusion: There is a strong correlation between PROMIS scores and legacy measures evaluating outcomes after surgical management of capitellar OCD. However, large ceiling and floor effects were present in all measures, likely owing to the favorable clinical results. The KJOC score was limited the least by ceiling and floor effects.
