Osteochondral Allograft Transplantation to the Capitellum: Technical Considerations of a Mega Osteochondritis Dissecans Technique.

Osteochondritis dissecans of the elbow is a rare but debilitating pathology typically found in the adolescent repetitive overhead athlete. In the setting of unstable lesions, mechanical symptoms, or deteriorating function despite appropriate conservative management, surgical osteochondral allograft transplantation of the capitellum is a viable option for even large lesions (>10 mm), with minimal morbidity and good return of function. We describe a technique for performing a large osteochondral allograft transplantation of the capitellum.
