Durable Fixation Achieved With Medialized, High Hip Center Cementless THAs for Crowe II and III Dysplasia

Abstract

A high hip center total hip arthroplasty (THA) for dysplasia allows more complete socket coverage by native bone at the expense of abnormal hip biomechanics. Despite poor results with cemented components, intermediate-term results with cementless cups at a high hip center have been promising, but there are few reports at long-term followup without bone graft.
