R3 Delta Post-Approval Study U.S.

Post-Approval Study of the R3 Biolox Delta Ceramic Acetabular System - US The R3 Ceramic Acetabular System is indicated for use in skeletally mature patients requiring primary total hip arthroplasty due to non-inflammatory arthritis (degenerative joint disease) such as osteoarthritis, avascular necrosis, or traumatic arthritis. The expected timeline for the study is a total of approximately 5 years: 6 months for site initiation, 12 months for subject enrollment, 3 years until the last subject enrolled has reached the 3 year follow-up interval.

Inclusion Criteria:

• 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
• Patient is willing and able to participate in required follow-up visits and to complete study procedures and questionnaires
• Patient has consented to participating in the study by signing the IRB/EC approved informed consent form

Exclusion Criteria:

• Patients with insufficient quantity or quality of bone support; metabolic bone disease; osteoporosis
• Patients with neurological or muscular conditions that would place extreme load or instability upon the hip joint
• Patients with active joint infections or chronic systemic infection
• Obese patients where obesity is defined as BMI ≥ 40
