However, its efficacy in treating recurrent instability due to malposition cup is less reported. The aim of this study is to evaluate the outcome of this surgical technique to treat hip instability. From 2009 to 2019, we have identified 38 patients who had been surgically treated for recurrent instability, including cementation liner (<jats:italic>N<\/jats:italic>\u00a0=\u00a020) and revision cup (<jats:italic>N<\/jats:italic>\u00a0=\u00a018) procedures. Patients were followed for a mean of 45.66\u00a0months. We have recorded and analyzed all causes of implant failure including recurrent instability. Clinical outcomes were assessed including complication and Harris Hip Score (HHS) preoperatively and at the latest follow\u2010up. Revision\u2010free survivorship for any cause was 95.0% at 1\u00a0year, and 84.4% at 5\u00a0years in cementation liner group and 88.9% at 1\u00a0year and 5\u00a0years in revision cup group. Mean Harris hip score improved from 48.3 points preoperatively to 79.5 points at the last follow\u2010up in cementation liner group and mean HHS improved from 43.3 points preoperatively to 77.2 points in revision cup group. There were two implant failures in each group, including one is due to persistent hip instability and the other is due to periprosthetic joint infection in the cementation liner group and two implant failure are due to persistent hip instability in the revision cup group. Functional scores and implant survival were similar in both groups. We demonstrated that orientation correction via the cementation of the polyethylene liner into well\u2010fixed acetabular shell is a promising option to treat and prevent instability.<\/jats:p><jats:p>Level of Evidence: Therapeutic Level
