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

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.
