Dual Mobility Acetabular Cups in Revision TJA
Rush University Medical Center
Summary
The aim of this study is to the compare clinical outcomes of patients undergoing a revision total hip arthroplasty (THA) with the use of a dual mobility bearing versus a single bearing design with the use of a large femoral head (36mm or 40mm). We hypothesize the use of dual-mobility components in revision THA will be associated with a lower dislocation rate in the first year following surgery.

Inclusion Criteria: * Any patient older than 18 years of age scheduled for a revision THA, including revision of both components, conversion of a hip resurfacing to THA, conversion of a hemiarthroplasty to THA, and revision of single components which allow implantation of dual-mobility bearings. In addition, patients undergoing reimplantation of a total hip arthroplasty following a two-stage revision for periprosthetic infection will also be included. Only patients with an acetabular shell diameter capable of accommodating at least a 36mm femoral head will be included. Exclusion Criteria: *…
