Comparison of Clinical Outcomes after Modified Brostr?m Procedure with or without Calcaneofibular Ligament Repair for Chronic Lateral Ankle Instability: A Prospective Randomized Control Study

摘要

Category:SportsIntroduction/Purpose:Modified Brostrom procedure has been the choice of treatment for chronic lateral ankle instability(LAI). However, there is a controversy about the necessity for repair of calcaneofibular ligament(CFL). Thus, we designed a prospective randomized control study to investigate if there is any difference according to calcaneofibular repair.Methods:Between June 2012 and September 2015, 48 patients with chronic LAI were enrolled in this study after our IRB(file No. 2012-02-046-035) approved it. They were divided into two groups(24 for each) by a random manner. Inclusion criteria are as following: age of 20 to 60 and chronic mechanical LAI who had failed in conservative treatment for more than 6 months. Patients with inflammatory diseases and history of previous surgery for the same ankle were excluded. Modified Brostrom procedure was done for the patients with informed consent. For group A we repaired both ATFL and CFL, and for group B only ATFL was repaied. Postoperative reha...
