INTRODUCTION: Ankle sprains are very common injuries, especially in athletes. Approximately 3,0% of cases develop with anterolateral impingement, a common cause of chronic joint pain and functional ankle instability. METHODS: Clinical evaluation of patients with anterolateral impingement submitted to arthroscopy debridement, between February 2008 and October 2014. All patients were evaluated using the AOFAS ankle score, numeric pain scale and satisfaction index with the result of the surgery. The Mann-Whitney test was used for statistical analysis. RESULTS: 26 patients, submitted to resection of the anterolateral ankle arthroscopic impact were evaluated. The mean time between injury and surgery was 33.1 months, with a mean follow-up of 31.2 months. A mean AOFAS score of 84.5 points was obtained, mean pain scale was equal to 2, and 92.3% of the patients stated they were satisfied with the surgery performed. CONCLUSION: Chronic pain and functional ankle instability can be treated by arthroscopic debridement of the anterolateral impingement. Chronic pain and functional  ankle instability can be treated by arthroscopic resection of anterolateral impact. The results of the surgery, such as pain improvement and the result evaluated by the AOFAS score, were not related to the patient’s gender, alongside the lesion, the time between injury and surgery, and the postoperative time.
