Synovial chondromatosis is a rare pathology in the foot and ankle region. We present a case of concomitant tenosynovial chondromatosis of the extensor digitorum longus tendon and synovial chondromatosis of the ankle, which was successfully treated by extensor digitorum tendon tendoscopy and ankle arthroscopy.
