The Patient With Chronic Total Hip Arthroplasty Dislocations: A Case Series of Five Patients Who Underwent Revision THA Using Polypropylene Mesh for Capsular Reconstruction

We report a case series of 5 patients who underwent revision total hip arthroplasty (THA) using a polypropylene mesh for capsular reconstruction for chronic THA instability. The average follow-up is 16.6 months (range, 9-20 months). There were no postoperative dislocations in our series. Three patients had previous infections with two-stage revisions before final revision surgery and were infection free at their most recent follow-up. One patient developed a prosthetic joint infection 2 months postoperatively. The use of a polypropylene mesh appears to be another tool that surgeons can use when dealing with the difficult dilemma on how to treat the patient with chronic THA instability and severe abductor and capsular tissue loss.
