Foot and Ankle Giant Cell Tumors Are Not so Aggressive After All: A Retrospective Study.

Giant cell tumors are most commonly seen around the knee and rarely around the foot and ankle. Therefore there is a paucity of data regarding the options of surgery, outcomes and recurrence of Giant cell tumors involving the foot and ankle. We retrospectively studied patients with Giant cell tumors of the foot and ankle from January 2009 to December 2017. We identified 19 (N = 19) patients with a minimum of 1-year follow-up. Their data was retrieved from the electronic database and analyzed. The mean follow-up period was 36.2 (range 12-96) months. On an average, the patients underwent 1.6 surgeries. The surgeries performed were extended curettage and bone graft/cement in 8 (42.1%) patients, excision and bone graft in 8 (42.1%) patients and excision and mega prosthesis in 3 (15.79%) patients. The most common complication was wound infection seen in 3 (15.79%) patients. None of the patients who underwent index procedure in our center (biopsy and surgery) had local recurrence. There were 9 (47.36%) patients with primary procedure elsewhere - 7 of them had no recurrence after surgery in our center. One (5.26%) amputation was eventually performed due to complications and not as a primary surgery. At the final review, all 19 (100%) patients with >1 year follow up were in remission. Local recurrence and wound infection were exclusively found in patients who presented to us after invasive procedures done elsewhere. With good surgical clearance, the uncommon presentations of foot and ankle Giant cell tumors can be treated to attain complete remission.
