Brief Summary:
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.

A hemispherical acetabular shell indicated for cementless application.

Primary Outcome Measures :
  1. Absence of Revision for the Trident II Tritanium Acetabular Shell [ Time Frame: 5 years ]

Secondary Outcome Measures :
  1. All-cause Revision and Removal Rates for the Trident II Tritanium Acetabular Shell [ Time Frame: 10 years ]
    Survivorship percentage (one reported value) for both all-cause revision + removal will be indicated

  2. Radiographic Stability [ Time Frame: 6 weeks, 3-6 months, 1, 2, 5, 7, 10 years ]
    Numerous parameters will be reviewed by zone, including radiolucency and migration.
