Abstract
The purpose of the present study was to evaluate the results of arthroscopic and endoscopic treatment of concurrent anterior and posterior ankle impingement with the patient in a prone position. From May 2009 to September 2010, 22 patients with simultaneously combined anterior and posterior ankle impingements underwent ankle arthroscopy in a prone position. Noninvasive ankle distraction was achieved by hanging the affected ankle on a shoulder-holding traction frame, followed by hindfoot endoscopy. The mean age at surgery was 22.6 (range 20 to 46) years. The mean follow-up duration was 15.4 (range 12 to 29) months. The American Orthopaedic Foot and Ankle Society scores and Foot Function Index were checked preoperatively and at the final follow-up visit. The mean American Orthopaedic Foot and Ankle Society score increased from 62.6 preoperatively to 86.0 at the final follow-up visit (p < .05). The Foot Function Index improved from 45.8 to 17.2 (p < .05). Of the 22 patients, 18 were very satisfied or satisfied with the results, 2 rated their results as fair, and 2 were dissatisfied. No complications related to ankle distraction in a hanging position occurred. Ankle arthroscopy with the patient in a prone position with the ankle hung on a shoulder-holding traction frame combined with hindfoot endoscopy provided a useful method for treating anterior and posterior ankle impingement that does not require changing the patient's position from supine to prone.
