Abstract

Objective The present study assesses the results of a minimally invasive surgical technique for acute and chronic ankle instability management. Methods The present case series study retrospectively evaluated 40 patients undergoing arthroscopic-assisted percutaneous ankle ligament reconstruction from 2013 to 2019. Results The present study included 17 males and 23 females with an average age of 38.3 years old. Postintervention follow-up using American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scores identified improvement of > 30 points in function and pain control. The most frequently occurring associated injuries were osteochondral (35%). No patient required reintervention or had infection during follow-up. Conclusion The technique in the present study is easy and achieves satisfactory results for function and pain control. Level of Evidence IV.

Keywords: ankle joint; arthroscopy; joint instability; ligaments, articular; subtalar joint; tendons.
