Dual Mobility Acetabular Cups in Revision TJA
Dislocation, Hip
About this trial
This is an interventional prevention trial for Dislocation, Hip
Eligibility Criteria
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.

Active Comparator
Dual Mobility
Conventional, Single-bearing hip implant
If patients are randomized to the dual mobility cohort, they will receive a dual mobility prosthesis at the surgeon's discretion. All surgeries will be performed via the posterior approach, per the participating surgeon's usual standard. Patients will be on postoperative hip precautions for 6 weeks, per departmental protocol. No braces will be utilized.
If patients are randomized to the conventional, single bearing cohort, surgeons will use their preferred implant design at their discretion using a 36 or 40mm head, depending on the diameter of the cup and manufacturer specifications. All surgeries will be performed via the posterior approach, per the participating surgeon's usual standard. Patients will be on postoperative hip precautions for 6 weeks, per departmental protocol. No braces will be utilized.
