Tratamento artroscópico do impacto femoroacetabular

Abstract

Objective: The purpose of this study is to evaluate the short- term follow-up results of arthroscopic treatment of femoro- acetabular impingement. Our hypothesis is that arthroscopic treatment results are favorable. Methods: Between August 2003 and August 2007, 28 hips had femoroacetabular im- pingement treated by hip arthroscopy. The mean age was 34 years, with mean follow-up period of 27 months. Clini- cal results were graded with the modified Harris hip score, which was measured pre- and postoperatively. Patients had also their internal rotation analyzed. These parameters were calculated by using Wilcoxon's t test for analysis of nonpara- metric paired samples performed. Results: The mean preop- erative Harris Hip Score was 54.2, improving to 94.8 post- operatively (p<0,001). The mean increase was 37.5 points. We had 4 good results (15%) and 24 excellent results (85%). Preoperatively, the patients had a mean internal rotation of 17°, and, postoperatively, 36°. The average internal rotation increase was 19° (p<0,001).Conclusions: The arthroscopic treatment of femoroacetabular impingement presents satis- factory results.
