Percutaneous bipolar radiofrequency microdebridement for recalcitrant proximal plantar fasciosis.

Success rates for traditional methods of surgical intervention for chronic plantar fasciosis are low, and associated with high rates of complications and long recovery times. The purpose of this prospective case series was to assess the effectiveness of percutaneous bipolar radiofrequency microfasciotomy for the treatment of recalcitrant proximal plantar fasciosis in 21 patients. The mean preoperative American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score was 22.10 ± 12.96 (out of a possible 68 points) and the mean postoperative AOFAS hindfoot score was 59.57 ± 13.23 points, and this difference was statistically significant (P < .0001). A total of 7 (33.33%) patients experienced satisfactory pain relief within 1 to 4 weeks and 10 (47.62%) did so within 1 to 4 months, whereas 2 (9.52%) patients required longer than 4 months, and 2 (9.52%) others never attained satisfactory relief of symptoms. Fourteen (66.67%) patients subjectively rated their outcome as excellent, 4 (19.05%) as good, 1 (4.76%) as fair, and 2 (9.52%) as poor. One (4.76%) patient experienced iatrogenic flexor hallucis longus tendonitis. The results of this clinical investigation indicate that bipolar radiofrequency microdebridement plantar fasciotomy safely alleviates recalcitrant heel pain. The technique is minimally invasive and simple to perform, and it spares the overall integrity of the plantar fascia without being associated with undue complications.
