Abstract
Presently, there are multiple options for prevention and treatment of hip dislocation in the revision setting. These include large head prostheses, tripolar constructs, dual mobility liners, and constrained liners. In spite of having better options than 10–15 years ago, revision for total hip arthroplasty constructs that have recurrently dislocated remain in the 15–20% failure range. Especially with cases of deficient abductor hip muscles and marked joint laxity, it is imperative that constrained liners remain in the surgeon׳s armamentaria at the time of revision surgery.
