Abstract
Dual-mobility hip components provide an additional articular surface, with the goals of improving range of motion and overall stability. In many European centers, these components are used for primary total hip arthroplasty. However, their greatest utility may be to prevent and treat recurrent dislocation after revision total hip arthroplasty. Several retrospective series have shown satisfactory results for this indication at medium-term follow-up. There are important concerns with these components, including intraprosthetic dislocation and polyethylene wear causing chronic dislocation, but these are rare phenomena. At present, dual-mobility components are the preferred solution to manage recurrent dislocation in revision surgery.
