Abstract

PURPOSE: The purpose of this study is to evaluate the surgical results of modified Brostrom procedure for chronic lateral ankle instability and to assess whether or not associated injuries may affect postoperative satisfaction.
MATERIALS AND METHODS
Twenty-four patients with chronic lateral ankle instability were evaluated retrospectively from August 1998 to March 2002. Average age was 29.3 years. All patients were performed pre & postoperative ankle anteroposterior and lateral view, stress anterior drawer and varus test using Telos device, MRI and intraoperative arthroscopic evaluations before ligament reconstruction.
RESULTS
Of the 24 cases, 23 cases was improved more than average 12 points on AOFAS scales. On modified scales of Hamilton, 3 excellent, 20 good, 1 fair results. On stress view, average 2.2 mm difference was improved on anterior drawer test and average 1.7 degree on varus test. Associated injuries were 8 osteochondral defects, 4 anterior impingements, 2 loose bodies, 2 os subfibulare, 2 os submalleolare and 2 partial ruptures of peroneus brevis. 8 cases with no associated injuries rated excellent or good.
CONCLUSION
The modified Brostrom procedure is believed to be an effective and successful method for chronic lateral ankle instability that didn't respond to conservative treatment. Because associated injuries in chronic lateral ankle instability may affect postoperative satisfaction, appropriate detection and treatment may need for postoperative satisfaction.
