Synovial chondromatosis: A disorder of a joint featuring a change of the normal joint lining (synovium) tissue's cellular structure to form cartilage tissue. Synovial chondromatosis is rare. Synovial chondromatosis leads to pain in the affected joint as well as limitation of the range of motion and often locking.
The cause of synovial chondromatosis is not known.
Treatment of synovial chondromatosis typically involves surgical removal of the joint lining tissue.
