Dual Mobility in "High Risk" Patients

This study aims to compare the clinical outcomes of patients considered to be at high risk for prosthetic dislocation undergoing primary total hip arthroplasty (THA) with the use of a dual mobility bearing versus a conventional, single-bearing design. We hypothesize that in primary THA patients considered to be at high risk for prosthetic dislocation, the use of dual-mobility components will be associated with a lower dislocation rate in the first year following the index procedure. We do not anticipate a difference. In other clinical outcome measures or functional outcome scores between the two cohorts. Study Design: Randomized controlled trial with two groups: THA with dual mobility. 44 components vs THA with single-bearing designs
