Endoscopic Plantar Fasciotomy; Deep Fascial Versus Superficial Fascial Approach: A Prospective Randomized Study.

In the present randomized prospective study, 2 different surgical techniques of endoscopic plantar fascia release were compared. Of 547 patients with a diagnosis of plantar fasciitis, 46 with no response to conservative treatment for ≥6 months were included. Of the 46 patients, 5 were lost to follow-up. In group 1 (n = 21), plantar fascia release was performed using a deep fascial approach (DFA), and in group 2 (n = 20), the superficial fascial approach (SFA) with a slotted cannula technique was used. Patients were evaluated using the American Orthopaedic Foot and Ankle Society Ankle Hindfoot scale and visual analog scale at baseline and 3 weeks and 3, 6, and 12 months after the initial surgery. At the final follow-up appointment, the Roles-Maudsley score was used to determine patient satisfaction. At the final follow-up examination, the mean American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale scores had increased from 53.12 to 83.68, with a decrease in the mean visual analog scale score from 7.95 to 1.65 noted. According to the Roles-Maudsley score, the success rate after 1 year was 90.47% for DFA group, 95% for the SFA group, and 92.68% for all patients. Although no significant difference was found between the final functional scores, better early postoperative scores were found in the SFA group. The mean duration of the procedure was measured as 27.22 ± 9.41 minutes overall, 35 ± 5.62 minutes in the DFA group, and 19.05 ± 4.01 minutes in the SFA group. Two early and two late complications occurred in the DFA group with none reported in the SFA group. In conclusion, the SFA is a faster and safer method of endoscopic plantar fascia release with better early postoperative scores.
