Osteochondral Autograft
Osteochondral autografting (OCG) is a surgery to repair damaged articular cartilage that lines the ends of bones in a joint. An osteochondral autograft is a piece of tissue taken from a healthy section of the joint and transplanted to replace the chondral defects in the joint. There are two techniques used in osteochondral autografting: mosaicplasty and osteochondral autograft transfer system (OATS).
