What this Trial Is About
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.
