Quick Summary

Synovial osteochondromatosis is a benign condition where numerous cartilaginous nodules, sometimes containing bone, form in the soft tissues of a joint. This condition most commonly affects a single joint, particularly the knee, and is often seen in young to middle-aged adults. While the cause is frequently unknown, it can sometimes develop secondary to other joint diseases like rheumatoid arthritis or osteoarthritis. Treatment typically involves surgical removal of affected parts of the synovial membrane, and the condition is usually cured, with malignancy being rare.1
