Recurrent Dislocation After Total Hip Arthroplasty: Controversies and Solutions.
Instability remains one of the most common complications after total hip arthroplasty and a notable cause of patient morbidity as well as patient and surgeon dissatisfaction. Isolated dislocations can often be managed successfully with closed reduction; however, recurrent instability poses a substantial diagnostic and therapeutic challenge. The causes are varied and may be related to patient, surgical, and implant factors. A thorough evaluation is important in determining the cause of instability and effectively managing this difficult problem. Management options include component revision for malposition, modular exchange, or revision to specialized components, such as larger femoral heads, constrained liners, or dual-mobility articulations.
