|"Synovial Chondromatosis is an uncommon benign disease. The knee is most frequently affected, but SC has been described also at the foot and ankle. Patients present with complaints of pain, locking, instability of variable duration and a palpable mass. Diagnosis is often delayed until the time of surgery. In this case report we focus on the clinical signs, differential diagnosis and especially in pearls and pitfalls for the surgical procedure. Lateral approach for resection of the tumor improves the patient foot deformity and ambulation.
Synovial chondromatosis (SC) is an uncommon proliferative process, most commonly involving the knee joint. Hystologically, it is characterized by the development of foci of cartilage in the synovial membranes. This then precedes the formation of loose bodies, which may result in pain, with or without joint catching and locking. The objectives of surgical treatment are to decrease pain, improve ambulatory function, and delay early osteoarthritis.
