Overview

Brief Summary

Treatment of osteochondral lesion of Talus with a devitalized viro-inativated sterile osteochondral graft. To avoid having to harvest autograft material from the knee, a processed allogeneic osteochondral can be used instead autograft. The surgical technique is to implant in the osteochondral defect one to three products in the defect.
