Operative Treatment for Ganglion Cysts of the Foot and Ankle

Abstract 

The authors analyzed the clinical results of surgical excision for symptomatic or recurrent ganglion cysts of the foot and ankle, and tried to elucidate the prognostic factors. Fifty-three cases of ganglions in the foot and ankle were followed for more than 24 months after excision. The mean duration of follow-up was 3.7 years. As a preceding treatment, 17 cases received a mean of 1.3 aspirations, and 16 cases recurred after a mean of 1.7 operations. The cyst was most common in the dorsum of the foot and ankle, where 35 cases were found. Thirty cases originated from the tendon sheath, 19 cases from the joint, and 4 cases from others. Preoperative mean AOFAS foot scores were low in the cysts associated with the tarsal tunnel syndrome, and in the cysts of the plantar aspect of the first toe. Postoperative mean AOFAS foot scores were significantly increased in the preceding 2 groups. There were 3 (5.7%) cases of recurrence, all of which originated from the tendon sheath. In the case of ganglion cysts originating from the tendon sheath, careful attention should be paid to locate satellite masses to avoid recurrence.
