Cemented liner in cementless cup

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.

The demographic data, reasons for use of such revision technique result was evaluated by Harris Hip Score.
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.
