Dislocation after total hip arthroplasty (THA) is the leading cause of revision surgery. Dual mobility (DM) implants have been utilized over the past 40 years as a means of addressing and preventing this morbid and expensive complication. Recently, there has been renewed investigation into the role that DM implants may play in reducing instability in high-risk patients. Hemiarthroplasty or traditional THA remain the mainstays of treatment for older patients with displaced femoral neck fractures. Longer-term higher-quality studies are necessary to investigate whether DM THA outcomes may be superior to traditional THA in the physiologically young patient with high physical demands and a longer-than-average life expectancy. The use of DM implants in preventing dislocation in patients with fixed spinopelvic alignment, neuromuscular disorders, and failed fixation of previously sustained proximal femoral fractures has shown success in studies with low levels of evidence. More robust prospective data are necessary before more widespread adoption of DM arthroplasty is recommended in these clinical scenarios. Knowledge of the pertinent literature with regard to the use of DM implants in patients who are at high risk for instability will allow orthopaedic surgeons to make informed decisions as to whether or not their patients may benefit from primary THA utilizing DM implants.
