Osteochondral Allograft for Post-Traumatic Knee DefectsWhen post-traumatic knee injury damages both cartilage and underlying bone, osteochondral allograft transplants provide a single-stage solution that other repair methods cannot match. Roughly 75–82% of patients return to sport; grafts show 87% survival at five years, declining to 68% at twenty.When post-traumatic knee injury damages both cartilage and underlying bone, osteochondral allograft transplants provide a single-stage solution that other repair methods cannot match.
