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.


Study Type: Observational
Study Design: Observational Model: Other
Time Perspective: Prospective
Official Title: A Prospective, Multicenter, Non-randomized, Clinical Outcomes Study of the R3® Acetabular System in Patients With Degenerative Hip Disease

Further study details as provided by Smith & Nephew, Inc.:

Primary Outcome Measures:
  • Effectiveness will be measured using the Harris Hip Score (HHS), The HOOS self assessment questionnaire, and radiographic assessment. Radiographic measures consist of radiolucencies, component position changes, and bony changes. [ Time Frame: 3 months, 1-5 years ]
    The objective of this study is to establish the safety and effectiveness of the R3 Acetabular System in primary total hip replacement.

Secondary Outcome Measures:
  • Adverse Events [ Time Frame: Post Operative - 5 years ]
    All perioperative and postoperative device-related and surgical adverse events will be recorded during this study.

Estimated Enrollment: 158
Study Start Date: October 2009
Estimated Study Completion Date: April 2017
Primary Completion Date: February 2017 (Final data collection date for primary outcome measure)
Detailed Description:
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.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
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.

Inclusion Criteria:

  • Patient is of legal age to consent and skeletally mature.
  • 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 retardation, or drug, alcohol abuse.
  • Patient has BMI >40.
  • Patient is a prisoner
