All-inside Arthroscopic Modified Brostr?m Operation for Lateral Ankle Instability with Os Subfibulare:

摘要

Category:SportsIntroduction/Purpose:Os Subfibulare(OSF) is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle. Patients with chronic lateral ankle instability (CLAI) have a high incidence of OSF, and there relationship implies that there is a correlation between OSF and CLAI. The all-inside arthroscopic Modified Brostr?m Operation (MBO) has been developed for the treatment of chronic lateral ankle instability (CLAI) and the outcome was reported as good or excellent. But there were no report about comparison of the outcome between OSF and non-OSF patients with chronic lateral ankle instability treated by all-inside arthroscopic MBO. The purpose of this study was to evaluate the clinical and radiologic outcomes of the arthroscopic MBO procedure for CLAI with or without OSF.Methods:From January 2013 to september 2016, arthroscopic MBO was performed on 133 patients with CLAI. Of these, 126 ankles were evaluated for this study. Patients were divided into two groups: the OSF group (...
