Synovial osteochondromatosis is a rare synovial proliferative disease that occurs because of chondral metaplasia within the synovium. This disease can occur intra- or extra-articularly. Etiology is ultimately unknown. When conservative treatment fails, the cartilaginous nodules should be surgically removed. Although it has been reported all over the body, cases within the foot and ankle are far less common. We report a case of successful management of osteochondromatosis in an adult male that was surgically managed through a standard anterior ankle approach. At over two years of follow-up, he has since presented with no recurrence of synovial osteochondromatosis, significant reduction of pain post-operatively and has returned to full activity level.
