Background: Cementation of polyethylene liners into well-fixed cementless metal shells has become an option during revision total hip arthroplasty (THA). We report the results of cementing a dual-mobility (DM) component into a stable acetabular shell in high-risk patients undergoing revision THA.

Methods: A single-centre series of 10 patients undergoing revision THA with a DM cup cemented into an existing well-fixed shell between 2012 and 2016 were retrospectively reviewed. Failure due to aseptic loosening or instability and implant survival at last follow-up were analysed. The average age was 79.2 years and mean follow-up was 3.5 years. Indications were recurrent hip dislocation in 8 cases and intraoperative instability with moderate abductor insufficiency in 2 cases. In cases with recurrent dislocation, the aetiology of instability was classified by Wera type.

Results: At the late...
