Abstract
OBJECTIVES: This retrospective study aims to evaluate the outcome of cementing dual-mobility articulation into porous revision shells.
METHODS: From a total of 102 revision hips between 2015 and 2021 in our revision database, we identified 47 cemented dual-mobility articulations. Indications for revision total hip arthroplasty (rTHA) included aseptic failure of acetabular shell (n = 34), infection (n = 7) and dislocation. We included patients with a cemented dual mobility articulation in a porous revision shell and a minimum of 1 year follow-up.
RESULTS: No complications were noted intraoperatively. There was no dislocation and no radiological signs of loosening at latest follow-up. The mean Oxford Hip Score improved from 24 (SD 13) preoperatively to 42 (SD 15) postoperatively. There was no revision and no peri-prosthetic joint infection.
CONCLUSIONS: Cementing a dual-mobility shell into a well-fixed porous revision shell is an appropriate technique to achieve the desired stability and orientation of the acetabular construct and restore the hip centre.
