A Prospective, Multicenter, Non-randomized, Clinical Outcomes Study of the R3® Acetabular System in Patients With Degenerative Hip Disease
This is a prospective, non-randomized, consecutive series, multicenter clinical study that
will include patients who will have total hip replacement with the R3 Acetabular System.
will include patients who will have total hip replacement with the R3 Acetabular System.
The study design was selected to assess the safety and effectiveness profile of the R3
Acetabular System in patients with degenerative joint disease requiring primary total hip
replacement. A non¬-randomized, consecutive series of up to 158 patients will be enrolled,
and a maximum of 8 sites will participate in the study. Each site is allowed to enroll up to
22 patients. When 158 patients are enrolled from all sites, enrollment will be stopped,
regardless of the number contributed from each site. The clinical data from this study will
be compared with a historical control. The study will include follow up through 5 years.

Inclusion Criteria:

- Patient requires primary total hip arthroplasty due to non-inflammatory degenerative
joint disease (e.g. osteoarthritis, traumatic arthritis, avascular necrosis, and
dysplasia/DDH)
- Patient has met an acceptable preoperative medical clearance and is free from or
treated for cardiac, pulmonary, hematological, etc., conditions that would pose
excessive operative risk.
- The patient will be available for follow-up throughout the duration of the study.
Exclusion Criteria:
- Patient has active infection or sepsis (treated or untreated)
- Patient has any vascular insufficiency, muscular atrophy, or neuromuscular disease
severe enough to compromise implant stability or postoperative recovery.
- Patient is pregnant or plans to become pregnant during the course of the study
Patient has inadequate bone stock to support the device (e.g. severe osteopenia,
family history of severe osteoporosis or osteopenia)
- Patient has inflammatory joint disease (e.g. rheumatoid arthritis)
- Patient has known moderate to severe renal insufficiency.
- Patient has a known or suspected metal sensitivity.
- Patient is immunosuppressed or receiving high doses of corticosteroids.
- Patient has an emotional or neurological condition that would pre-empt their ability
or willingness to participate in the study including mental illness, mental
