Dual Mobility Acetabular Cups in Revision Total Joint Arthroplasty

This study is comparing two types of hip implants used in revision total hip arthroplasty (THA), which is surgery to replace an artificial hip joint. Researchers want to see if a "Dual Mobility Implant" leads to fewer dislocations compared to a "Conventional, single-bearing implant." You might be able to join if you are over 18 and scheduled for a revision THA. The main goal is to see how many dislocations occur at 6 weeks, 3 months, and 2 years after surgery. The current recruitment status is unclear.

Study design

Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for prosthetic dislocation at 6 weeks, 3 months, and 2 years after surgery.

Eligibility criteria

Inclusion

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

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.
