According to results published in the Journal of Arthroplasty, dual mobility acetabular cups may have comparable risks of aseptic revision and dislocation vs. metal or ceramic femoral head or unipolar constructs in total hip arthroplasty. 

Geoffrey H. Westrich, MD, hip and knee surgeon at HSS shares his perspective on the results. 

“Many would agree that dual mobility hips have helped reduce the risk of dislocation, and many surgeons appreciate the fact that dual mobility hips are more stable than traditional, fixed-bearing hips. There are many studies in the literature, both in primary hip replacement and in revision hip replacements, where dual mobility hips are used, and the dislocation rates are extremely low. There is a consensus that dual mobility hips are used for patients who are at higher risk for instability, because dual mobility implants have solved the instability problem,” explained Dr. Westrich.
