Two-stage revision with pseudocapsular resection for recurrent dislocation of total hip prostheses

Recurrent dislocation of the prosthesis is a problem with total hip arthroplasty. In the rare cases in which no identifiable cause can be found for the recurrent dislocation, we believe that the answer lies in addressing the large, sterile, fluid-filled cavity bounded by pseudocapsule, which we have noticed to form around the neck of the femoral implant in these cases. We report a 2-stage surgical technique that we have used successfully in 3 cases of recurrent dislocation without an identifiable cause, with an average follow-up of 3 years.
