Primary total hip arthroplasty is a successful procedure, although complications such as dislocation can occur. In certain patient\npopulations if this is recurrent, it can be difficult to manage effectively. We present a retrospective analysis of our experience of\nusing a capture/captive cup over an 8-year period for frail elderly patients who presented with recurrent hip dislocations. Our\nfindings show no re dislocations in our cohort and a survival analysis demonstrates just less than half surviving at 2 years after\nsurgery. Furthermore, Harris Hip Scores were generally calculated to be good. A constrained acetabular component provides\ndurable protection against additional dislocations without substantial deleterious effects on component fixation. Such components\nshould be considered especially in a group of patients with comorbidities or those who are fragile, elderly, and low-demand in\nnature.
