Posterior capsular repair following total hip arthroplasty: a modified technique.

Abstract

Various techniques of posterior capsular repair following THA have been reported and studies have demonstrated the merits of posterior capsular repair with respect to decreasing the incidence of dislocation. Our modified technique using three sutures offers excellent fixation of the hip capsule on the greater trochanter. The small drill holes needed for the #2 Fiberwire minimize the risk of a greater trochanteric fracture through the drill holes and osteoporotic bone. To date, we have not experienced any complications or reaction to this material. The importance of a posterior capsule repair has been well documented in the literature. A rigid capsular repair can prevent excess internal rotation and therefore minimize the incidence of postoperative dislocation following THA.
