osteochondritis dissecans
Pronunciation: OS-tee-oh-kon-DRY-tis DIS-eh-kanz
Joint condition where bone and cartilage separate from the underlying bone due to lack of blood supply.
Full Definition
A joint condition affecting young athletes where a segment of bone and its overlying cartilage becomes separated from the underlying bone due to compromised blood supply. This condition most commonly affects the knee, elbow, and ankle joints in adolescent athletes engaged in repetitive impact activities. The separated fragment may remain in place or become loose within the joint, potentially causing pain, swelling, and mechanical symptoms. Treatment depends on the size and stability of the lesion and the patient's skeletal maturity.
Usage
