Dual Mobility Acetabular Cups in Revision TJA

Who can join

Ages 18 and older · All sexes

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:

* Less than 18 years of age, primary THA,
* conversion of non-arthroplasty femoral neck fracture fixation to THA,
* patients unwilling to participate.
* patients where the surgeon makes the intraoperative decision to use a constrained liner will be excluded.

About the study

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.
