Cryosurgery: an innovative technique for the treatment of plantar fasciitis.

A prospective study testing the efficacy of cryosurgery on painful plantar fasciitis of the heel was performed. Cryosurgery, a minimally invasive, percutaneous, office-based technique, was used to treat 59 consecutive patients (61 heels), who had failed prior conservative therapy and were considered surgical candidates. Patients were evaluated on an 11-point visual analog scale administered preoperatively and up to 1 year of follow-up. The mean pain rating (8.38) before cryosurgery (day 0) is statistically significant to the mean pain rating (1.26) at day 365 postoperatively. Pain decreased significantly after the procedure (analysis of variance, P < .0001). These results suggest cryosurgery is significantly effective in treating patients with recalcitrant plantar fasciitis. Cryosurgery offers a highly effective treatment modality after failed conservative treatment without resorting to open invasive outpatient surgery.
