Chondral and osteochondral injuries. Diagnosis and management.
Osteochondral lesions are relatively common and usually occur as a result of trauma. They often are unrecognized acutely and lead to osteochondral defects and eventually osteoarthritis. Detection of these lesions has been aided by bone scan, CT, and MR imaging. Acute osteochondral fragments can be replaced and internally fixed. Chronic osteochondral defects can be treated with several methods designed to stimulate healing by either fibrocartilage or healing by transplantation of bone and cartilage or cartilage alone. The goal of all treatment methods is to provide a stable, congruent joint surface, restore function, and prevent the evolution of osteoarthritis in the injured joint.
