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.

Further study details as provided by Stryker Orthopaedics:

Primary Outcome Measures:
  • To demonstrate, through absence of revision at 5 years postoperative, that acetabular replacement with the Tritanium® Acetabular Shell provides clinical results comparable to similar acetabular components. [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To study rates of screw fixation usage in Tritanium® Acetabular Shell (cluster hole) procedures and compare with those reported in the Trident® X3® Polyethylene Insert Study. [ Time Frame: Intraoperative ] [ Designated as safety issue: No ]
  • To compare pain, function and health related quality of life (QOL) between the Tritanium® Acetabular Shell group, the literature and the historical control group from the Trident X3 Polyethylene Insert Study. [ Time Frame: 1, 3, and 5 years ] [ Designated as safety issue: No ]

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • A. Patient has signed an IRB approved, study specific Informed Patient Consent Form.
  • B. Patient is a male or non-pregnant female age 18 years or older at time of study device implantation.
  • C. Patient has primary diagnosis of Non-Inflammatory Degenerative Joint Disease (NIDJD).
  • D. Patient is a candidate for a primary cementless total hip replacement.
  • E. Patient is willing and able to comply with postoperative scheduled clinical and radiographic evaluations and rehabilitation.

Exclusion Criteria:

  • F. Patient has a Body Mass Index (BMI) ≥ 40.
  • G. Patient has an active or suspected latent infection in or about the affected hip joint at time of study device implantation.
  • H. Patient has a neuromuscular or neurosensory deficiency, which limits the ability to evaluate the safety and efficacy of the device.
  • I. Patient is diagnosed with a systemic disease (e.g. Lupus Erythematosus) or a metabolic disorder (e.g. Paget's Disease) leading to progressive bone deterioration.
  • J. Patient is immunologically suppressed or receiving steroids in excess of normal physiological requirements (e.g. > 30 days).
