Abstract

Several studies have reported that adductor release improves adduction contracture in total hip althroplasty (THA).<BR>We have experienced many cases showing improvement of adduction contracture after THA without adductor release. One hundred and twenty-two hips of 122 patients who underwent THA from September 1998 to July 2000 were enrolled in this study. The subjects consisted of 17 males and 105 females, whose mean age at THA was 61.5 years (range; 24 to 86 years). The average duration of follow-up was 5.3 years (range; 5 to 6 years). The subjects were divided into following three groups according to their preoperative maximum abduction angle: highly adduction contracture group consisted of less than 0° (group A), slight adduction contracture group between 1° and 10° (group B), and no adduction contracture group more than 11° (group C).<BR>We found no difference in postoperative maximum abduction angle between the groups. We believe that adductor release is not always necessary in THA.
