 The purpose of this study is to evaluate the recovery of the hip abductor muscle strength of minimally invasive total hip arthroplasty(THA)through the direct anterior approach. We measured the isometoric abductor muscle strength of 152 THAs between May in 2005 and August in 2006 at the time of preoperative day, 1 week, 1 month and 3 months postoperatively. The strength of the hip abductor was 0.53 preoperatively, 0.49 at l week, 0.66 at 1 month, 0.83(Nm/kg)at 3 month postoperatively. The hip abductor strength significantly increased at 1 month and at 3 months postoperatively without significant decrease at 1 week postoperatively. Comparing with the uninvolved hip, the strength of the involved hip recovered at the same level of the uninvolved hip at 3 month postoperatively. This study demonstrated that the direct anterior approach completely preserved the strength of the hip abductor.
