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.
1994年至1997年间，采用后外侧（Moore）入路对180例因各种适应证行初次全髋关节置换术（THA）的患者进行了前瞻性研究。将这些病例随机分为两组，以评估后方关节囊缝合术在预防术后脱位中的作用。第1组（96例）采用后方关节囊缝合术进行关节置换术闭合；第2组（84例）未行关节囊缝合术进行闭合。随访期为38个月（范围12 - 60个月）。第1组未发生脱位，而第2组发生了2例脱位（2.3%）。虽然影响初次THA脱位的因素很多，但后方关节囊缝合术可能有助于预防采用后外侧入路的初次THA发生后脱位。
