Abstract

Introduction: In some special situations during the revision total hip arthroplasty with well fixed, well oriented acetabular cementless cup, orthopedic surgeons may prefer to retain the well‐fixed cementless cup. The aim of this study was to report the follow‐up of some cases treated with such a technique during a 10‐year period. Methods: During 2004‐2014, all cases of revision total hip surgery performed in Sina Hospital, Tehran, Iran were evaluated. 14 of 82 cases (16.5%) had cemented polyethylene liner in cementless metal shell. The demographic data, reasons for use of such revision technique result was evaluated by Harris Hip Score. Results: The most common reason was osteolysis (64%), and the most common cause was impaired locking mechanism (65%). There were few complications (one osteolysis and one infection). In five cases (36%) constrained liner was added and in 10 cases (72%) allograft was needed. The final Harris Hip Scores was good or excellent in 78%. Only one dislocation was seen. Conclusion: Cemented cup in cementless shell can be used in revision hip arthroplasty in well‐fixed Acetabular shell situations with acceptable outcom.
