title: The effect of posterior capsulorrhaphy in primary total hip arthroplasty: a prospective randomized study.
abstract: Between 1994 and 1997, 180 cases of primary total hip arthroplasty (THA) were performed with the posterior (Moore) approach for a variety of indications and studies prospectively. The cases were separated randomly into 2 groups to evaluate the effect of posterior capsulorrhaphy in the prevention of postoperative dislocation. In group 1 (96 cases), closure of the arthroplasty was performed with a posterior capsulorrhaphy; in group 2 (84 cases), closure was performed without capsulorrhaphy. The follow-up period was 38 months (range, 12-60 months). No dislocations occurred in group 1, whereas 2 dislocations (2.3%) occurred in group 2. Although the factors affecting dislocation in primary THA are many, a posterior capsulorrhaphy may be helpful in the prevention of posterior dislocation of primary THA performed with a posterior approach.
