Fresh Osteochondral Allograft for Large Talar Osteochondral Lesions

Abstract

Osteochondral lesions of the talus are being recognized as an increasingly common injury. Large osteochondral lesions have significant biomechanical consequences and often require resurfacing with both boney and cartilaginous graft. The current treatment options include osteochondral autograft transfer, mosaicplasty, autologous chondrocyte implantation, or osteochondral allograft transplantation. Allograft procedures have the advantage of no donor site morbidity and ability to match the defect line to line. Careful transportation, storage, and handling of the allograft are critical to success. The failure of nonoperative management, failure of arthroscopic treatment, or large defects are an indication for resurfacing.
