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.
Synovial chondromatosis generally affects only a single joint. The most common joints involved are the knee, hip, or elbow.
Synovial chondromatosis can be diagnosed by an imaging test of the joint, such as CAT scan or MRI scan.
Treatment of synovial chondromatosis typically involves surgical removal of the joint lining tissue.
When bone-like calcium-containing tissue is also produced in the abnormal joint lining, the condition is referred to as synovial osteochondromatosis.

- Synovial cyst, popliteal
A swelling in the space behind the knee (the popliteal space). The swelling is composed of a membrane-lined sac filled with synovial fluid that has escaped from the joint. Commonly called Baker’s cyst.
- Synovial lining
The lining of the joints, normally only one or two cell layers thick, that is responsible for the production of the joint fluid. Also known as synovium.

- Synovial membrane
A layer of connective tissue that lines the cavities of joints, tendon sheaths, and bursae and makes synovial fluid, which has a lubricating function.

A disorder of a joint that features a change of the normal synovial lining’s cellular structure to form bone-cartilage tissue. Synovial osteochondromatosis is uncommon and typically seen in young to middle-aged adults.
