Ganglions of the foot and ankle. A retrospective analysis of 63 procedures.

A retrospective study was conducted to evaluate treatment of foot and ankle ganglion cysts seen at the Foot and Ankle Institute at the Pennsylvania College of Podiatric Medicine (now Temple University School of Podiatric Medicine). From 1990 to 1997, 63 patients (63 ganglion cysts) were treated by conservative or surgical means. Statistical analysis of data collected showed a significant relationship between type of treatment received and recurrence of the cyst. Surgical intervention resulted in significantly less recurrence (11%) than conservative treatment (63%). Regardless of whether treatment was conservative or surgical, there was no significant relationship between location of the cyst and recurrence. The type of conservative treatment was not significantly related to recurrence of the cyst. The surgical recurrence rate reported here is comparable to that reported in other studies of foot and ankle ganglion cysts. The number of foot and ankle ganglion cysts evaluated in this study is the largest in the literature.
