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

Recurrent dislocation of the prosthesis is a problem with total hip arthrop lasty. In the rare cases in which no identifiable cause can be found for th e 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 cas es of recurrent dislocation without an identifiable cause, with an average follow-up of 3 years.
