ABSTRACT Patients undergoing a revision total hip arthroplasty (THA) are at increased risk for dislocation. The literature suggests dual-mobility components may decrease the frequency of dislocation. We conducted a retrospective study of one type of dual mobility acetabular component implanted in 82 revision THA cases that were considered at increased risk for dislocation. Of the 82 hips, 58 had a mean follow-up of 12 months (3–28 months). The indication for revision was instability in 18 hips (31%), adverse metal-on-metal reaction in 13 hips (22%), reimplantation for infection in 11 hips (19%), and aseptic loosening of the acetabular component in 9 hips (16%). In the course of follow-up, 6 hips developed a deep infection requiring reoperation. There were no early hip dislocations.

Revision Tha

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 latest follow-up, Harris Hip Scores had improved from 49.3 preoperatively to 71.3 postoperatively ( p = 0.098). In the 8 patients with recurrent dislocation, 4 cases (50%) had an unclear aetiology (Wera type 6), 2 (25%) abductor deficiency (Wera type 3) and 2 (25%) late polyethylene wear (type 5). Postoperative recurrent dislocation occurred in 1 hip (10%). No cases of intraprosthetic dislocation, aseptic loosening of the previous shell or dissociation at the cement-cup interface were identified. Conclusion: Although the follow-up of this series is short, cementation of a DM cup into a previous well-fixed socket seems to be a viable option to treat and prevent instability after revision THA, without providing constraint at the cement-cup interface.
