Synovial Chondromatosis BoneTumor

Description: Synovial chondromatosis is the rare and benign metaplasia of the synovial membrane resulting in the formation of multiple intra-articular cartilaginous bodies. Synovial chondromatosis is known by several other names including articular chondrosis and synovial chondrosis. This self-limited and non-aggressive condition occurs most commonly in the knee followed by the hip, shoulder and elbow. It presents during the third to fifth decade twice as often in men than women and does not occur in children. Synovial chondromatosis presents as the gradual onset of monoarticular pain and stiffness. If allowed to continue, the slow, progressive symptoms can result in decreased range of motion, effusions, crepitation and eventual locking of the joint. This condition has also been described in the synovium, soft tissue and bursae. Secondary synovial chondromatosis may be present after long standing osteoarthritis.
