The purpose of this study is to review the performance and success rate of an FDA approved cementless hip replacement part called the Trident II Tritanium Acetabular Shell. The study will specifically look at the need to revise the hip replacement after 5 years. This will be compared to how much this happens in patients who have hip replacement with similar cementless acetabular shells.
