What is Osteochondral Autograft and Osteochondral Allograft Transplantation?
When the cartilage injury involves the underlying bone, the problem is now considered an “OSTEOCHONDRAL DEFECT” (OCD). These injuries require a different type of treatment where both the articular cartilage and the damaged bone are resurfaced. For smaller defects, a small plug of cartilage and bone is taken from a non-weight bearing area of the patient’s knee and is transplanted into the defect. This is called an osteochondral autograft. When the area of damaged cartilage is larger, an osteochondral allograft is used. In this case, a perfectly matched donor will be used and a plug of cartilage and bone is transplanted into the damaged area.
Your cartilage injury is unique and the surgeon will take many factors into account when choosing the best treatment. Cartilage injuries are complex problems.
