Lange J, et al. - This study was designed to explore patient outcomes after first-time revision total hip arthroplasty (THA) with dual mobility (DM) components for a diagnosis of instability. At average 3-year follow-up, a re-dislocation rate of 5% and an all-cause re-revision rate of 10% was reported in patients who had undergone first-time revision THA for instability using DM components. Additionally, it was observed that instability of unresolved etiology was associated with re-dislocation following revision surgery.
