Brief Summary

The objective of this study is to determine the long-term safety and effectiveness from the R3 Acetabular Hip System. The study hypothesis is that implant survivorship of the R3 cup is at least 97% at 3 years, 95% at 5 years, 93% at 7 years, and 90% at 10 years follow-up.

Outcome Measures

Primary Outcomes (1)

  • Implant Survivorship

    Implant survivorship by 10 years post study procedure measured by Kaplan-Meier survival rate. Implant survival determined by no revision required for any reason. A revision is a surgical procedure of the study hip where one or more of the study components are removed and replaced with new implants.

    up to 10 years post-operatively

Secondary Outcomes (7)

  • Patient Reported Outcome (PRO): Hip Disability and Osteoarthritis Outcome Score (HOOS)

    Pre-operative, 3 months, 1 years, 3 years, 5 years, 7 years, 10 years

  • Patient Reported Outcome (PRO): Modified Harris Hip Score (mHHS)

    Pre-operative, 3 months, 1 years, 3 years, 5 years, 7 years, 10 years

  • Patient Reported Outcome (PRO): University of California, Los Angeles (UCLA) Rating

    Pre-operative, 3 months, 1 years, 3 years, 5 years, 7 years, 10 years

  • Radiographic Findings: Atrophy

    1 years, 3 years, 5 years, 7 years, 10 years

  • Radiographic Findings: Hypertrophy

    1 years, 3 years, 5 years, 7 years, 10 years

  • +2 more secondary outcomes

Interventions

Total hip arthroplasty with the R3 Acetabular Hip system.

Study Population

This clinical study can fulfill its objectives only if appropriate subjects are enrolled. All relevant medical and non-medical conditions should be taken into consideration when deciding whether a particular patient is suitable. Subjects will be enrolled consecutively.

You may qualify if:

  • Patient is 18-75 years old and he/she is skeletally mature
  • Patient requires primary total hip arthroplasty due to non-inflammatory degenerative joint disease (e.g. osteoarthritis, post-traumatic arthritis, avascular necrosis, dysplasia/DDH or inflammatory joint disease (e.g., rheumatoid arthritis)
  • 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 is willing to comply the follow-up schedule

You may not qualify if:

  • Subjects with any of the following characteristics must be excluded from the participation in the study.
  • Patient has active infection or sepsis (treated or untreated)
  • Patient is a prisoner or has an emotional or neurological condition that would pre-empt their ability or unwillingness to participate in the study including mental illness, mental retardation, linguistic insufficiencies (i.e. immigrants), or drug/alcohol abuse.
  • Patients with acute hip trauma (femoral neck fracture)
