Fresh Precut Osteochondral Allograft Core Transplantation for the Treatment of Capitellum Osteochondritis Dissecans.

ABSTRACT: Osteochondritis dissecans (OCD) of the elbow is a disease of unclear etiology that affects young children and adolescents, particularly overhead athletes and gymnasts. Common surgical options include fixation, debridement, loose body removal, and marrow stimulation (microfracture/drilling). For large, deep, and/or uncontained defects, osteochondral autograft transplantation (OAT) has been advocated. However, there are some drawbacks to OAT, particularly related to donor-site morbidity. Fresh osteochondral allograft (OCA) transplantation avoids the donor-site morbidity associated with OAT and has been shown to be effective for treating capitellar OCD. This Technical Note details a surgical technique of OCA transplantation of the capitellum in an adolescent patient using a fresh precut OCA core. This procedure addresses the cartilage defect and loss of subchondral bone associated with OCD without the drawbacks associated with harvesting an autograft. Furthermore, as the graft is readily available, it avoids delays related to the donor-recipient matching process.

Project description:BackgroundCapitellar osteochondritis dissecans (OCD) lesions are common in athletes. Osteochondral autograft transfer (OAT) is one possible treatment option, though outcomes including return to sport (RTS) data are limited to small series. The purpose of this study was to systematically review RTS following OAT for capitellar OCD lesions. Our secondary objectives were to evaluate patient-reported outcomes (PROs), range of motion (ROM), and complications after OAT.MethodsPubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched for peer-reviewed articles on "osteochondral autograft transfer" and related terms for capitellar OCD lesions. Articles were included if they reported an RTS rate and had a follow-up time point of at least 12 months. Data on RTS rates, PRO measures, complications, and ROM were extracted. Articles were assessed for methodological quality using the Methodological Index for Non-randomized Studies criteria.ResultsSix hundred sixty-six articles were retrieved, and 24 articles (470 patients) met the inclusion criteria. In total, 454/470 patients (97%) returned to sports following OAT for OCD. The RTS rate ranged from 79% to 100%. Return to previous level of performance ranged from 10% to 100%. Timmerman-Andrews postoperative scores (range = 169-193) were most often reported, with 87% of patients showing scores within the excellent range. Disabilities of the Arm, Shoulder, and Hand and Japanese Orthopedic Association scores were also excellent postoperatively for all studies reporting, with higher scores among centralized lesions vs. lateral.ConclusionsFollowing OAT for capitellar OCD lesions, RTS rates are high; however, athletes should be counseled on the potential of a return to lower performance or the need to change positions. Lateral lesion location may negatively impact outcomes. PRO scores are typically excellent and postoperative ROM consistently improves. This information helps counsel patients regarding expectations and outcomes of OAT for OCD of the capitellum.
