Debridement of Chondral Defects of the Knee

– Discussion: (see osteochondral injury) – these injuries are distinct from degenerative arthritic lesions and management of these lesions should remain distinct as well; – theory is that penetration of subchondral bone causes bleeding from underlying vessels which allows clot formation in the cartilaginous defect and subsequent formation of fibrocartilage; – some argue that subchondral drilling … Read more
