Synovial chondromatosis of the ankle.

Synovial chondromatosis is a rare disorder presenting a typical radiological appearance. We reviewed three patients with this disease in the ankle. Two of these patients were reexamined after 7 and 27 years, respectively. Although both had several calcified juxta-articular bodies in the ankle none of them had any clinical symptoms. This indicates that surgical intervention should be performed only if mechanical signs and symptoms are present.
