Synovial chondromatosis is a rare, benign, proliferative cartilaginous lesion arising from the synovial tissue, tenosynovium, or bursal lining of or near joints. The term synovial osteochondromatosis is no longer used because the lesions are not only unrelated to osteochondromas but also not all ossified1. Synovial chondromatosis is found all over the body.

 It can be divided into primary and secondary forms; the primary form is uncommon, has unknown causes, and is generally monoarticular. It is between two to four times more frequent in men, occurring at any age group, most frequently between the 3rd and 5th decades of life2. Any joint may be affected, and the knee is the most frequent site (50-65% of the cases), followed by elbow, hips and shoulder in decreasing order of frequency3. The secondary form is a common condition caused by mechanical injury of the intraarticular hyaline cartilage triggered by joint anomalies such as osteoarthrosis, osteonecrosis, osteochondritis dissecans, neuropathic osteoarthropathy, trauma and rheumatoid arthritis. It is found in elderly patients, generally involving multiple joints, and may be related to degenerative joint disease, more frequently in the knees, hips and shoulders3.
