Abstract:
PURPOSE: To evaluate the results of surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum for chronic lateral ankle instability. MATERIALS AND METHODS: From April 2003 to August 2006, 62 patients with chronic lateral ankle instability were operated. There were 38 males and 24 females with a mean age of 39.6 years (range, 18~61 years). Mean follow-up period was 32 months (range, 10~48 months). All patients were checked with preoperative ankle anteroposterior and lateral view, stress anterior drawer and varus test using Telos device. The clinical results were graded according to the VAS and AOFAS scale. RESULTS: VAS score improved from preoperative 8.2 points to 3.1 points. There were 38 patients who were excellent (above 90 points), 18 who were good (between 76 and 90 points), 5 who were fair (between 60 and 75 points), and 1 who was poor (below 60 points) according to the AOFAS ankle and hindfoot scale. The excellent and good results amounted to 90.3%. CONCLUSION: Surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum is believed to be a effective method for chronic lateral ankle instability.
