Primary Intraarticular and Extraarticular Synovial Chondromatosis at Foot and Ankle: A Case Report and Review of Literature

Synovial chondromatosis is a benign condition in which the synovial tissue undergoes metaplastic changes into cartilagenous or osteocartilagenous bodies within joints, bursae or tendon sheaths. Knee, hip, shoulder, elbow are the commonly involved joints whereas foot and ankle joints are rare joints to be involved. They are classified into primary or secondary form depending on whether disease develops in apparently normal joint or in a pre-existent pathology like arthritis. Synovial chondromatosis can be intraarticular or extraarticular or combined. Here we report about a 52-year-old female presented with the history of mild swelling over right ankle associated with painful and terminal restriction of movement at ankle joint. She was operated with open excision of loose bodies and synovectomy. Postoperative histopathological examination confirmed the diagnosis of synovial chondromatosis without cellular atypia. Twelve months postoperative, patient was asymptomatic with no signs of recurrence.
