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.
