Overview

Synovial chondromatosis is a type of non-cancerous tumor that arises in the lining of a joint. The knee is most commonly affected, however it can affect any joint. The tumors begin as small nodules of cartilage. These nodules can separate and become loose within the joint.[1] Some tumors may be no larger than a grain of rice.[2] Synovial chondromatosis most commonly occurs in adults ages 20 to 50. Signs and symptoms may include pain, swelling, a decreased range of motion, and locking of the joint.[1][2] The exact underlying cause of the condition is unknown.[1] Treatment may involve surgery to remove the tumor. Recurrence of the condition is common.[1]
