Osteochondral Allograft Transplants for Large Trochlear Defects

Purpose: This article reports the authors’ technique of osteochondral allograft transplantation for the treatment of a focal full-thickness defect of the trochlea.

Summary: The advantages of using the described OCA technique is that it allows chondral defects to be immediately filled with mature articular cartilage, it avoids the donor-site morbidity, and histologic analysis of OCA has shown high survivorship of the transplanted hyaline cartilage.
