Abstract：Objective To explore the therapeutic efficacy of arthroscopic treatment for accessory anterolateral talar facet impingement syndrome (AATFIS).Methods The retrospective and descriptive study was conducted. The data of 12 patients (13 feet) with AATFIS who were treated in Xuzhou Central Hospital by arthroscopy in our department from June 2016 to August 2019 were retrospectively reviewed. The patients included eight females and four males with an average age of (38±11)years (range=13-51 years). Six left feet and seven right feet were analyzed. Five cases had combined peroneal spasm. All the patients were treated with accessory anterolateral talar facet (AATF) resection and joint debridement by subtalar arthroscopy. The effect of the operation was evaluated using scores in the American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot scale and visual analog scale (VAS) at the last follow-up.Results All patients had large AATF, eight cases had cartilage injury, 12 cases had anterior talocalcaneal ligament injury, five cases had interosseous talocalcaneal ligament injury, and four cases had synovitis. All surgical incisions healed in first stage. All patients were followed up in an average of(17.46±6.28)months (range=10-31 months). Peroneal spasm in three of five cases disappeared postoperatively, one case was relieved after the second surgical procedure (peroneal brevis tendon lengthening), and one case was not relieved of pain and refused the second operation. The average preoperative AOFAS and VAS scores were (47.69±13.42)points and (7.62±1.04)points respectively. The AOFAS and VAS scores at the last follow-up were (82.77±4.99) and (1.62±1.33) points, respectively, and the differences were statistically significant compared with those before surgery (t=10.180, 14.162; all P values＜0.01).Conclusions AATF resection and joint debridement by subtalar arthroscopy is a simple and effective method for the treatment of AATFIS.
