  Purpose

This study will be a prospective, non-randomized evaluation of the Tritanium® Acetabular Shell for primary total hip replacement (THR) with a cementless application in a consecutive series of patients who meet the eligibility criteria. Half of the cases will use the X3® polyethylene insert alone as the bearing surface; the other half will use the MDMTM liner coupled with a compatible ADM/MDMTM X3® insert as the bearing surface.

The success rate, defined as freedom from acetabular revision for any reason, for hips implanted with the Tritanium® Acetabular Shell, is no worse than for hips implanted with similar technology as reported in the literature and Trident® X3® Study historical control at 5 years postoperative.

Criteria

Inclusion Criteria:
