Hindfoot endoscopy for the treatment of posterior ankle impingement syndrome: a safe and reproducible technique.

INTRODUCTION: Posterior ankle impingement is a clinical syndrome characterized by posterior ankle pain that is mainly presented on plantar flexion. The aim of this study is to compare and evaluate the results of posterior ankle impingement treated by endoscopic hindfoot posterior portals.

MATERIALS AND METHODS: Between 2004 and 2009, a total of 38 endoscopic hindfoot procedures were performed to treat posterior ankle impingement. The indication for procedure was posterior ankle impingement syndrome in all cases. There were 38 patients, 17 females and 21 males. Mean age was 27.6 years (16-59 years). Mean follow-up was 27.6 months (12.5-52 months). The results were evaluated following the AOFAS score. Data statistical analysis was performed using the Student's t-test.

RESULTS: The main preoperative AOFAS score increased from 67.42 (range 41-91) to 97.13 (range 84-100) at follow-up. No complications were reported in any case.

CONCLUSION: Hindfoot endoscopy is a reproducible and safe procedure which offers excellent outcomes in posterior ankle impingement syndrome.
