Synovial Chondromatosis of the Foot and Ankle

Abstract

To our knowledge, this is the largest reported series of patients with SC of the foot and ankle. In half the patients, synovectomy with excision of loose bodies resulted in pain free return to normal function, without recurrence, at last followup. However, recurrence occurred in 3 (37.5%) of 8 patients with subsequent malignant transformation to low-grade chondrosarcoma occurring in 2 patients.
