Conditions
Intervention / Treatment
Detailed Description
This is a multicenter prospective observational post-market clinical follow-up study that will include 500 patients who will have total hip replacement with the R3 Acetabular System and either cemented or cementless hip stem.
Effectiveness will be assessed by comparison of changes in parameters contained in the HOOS questionnaire and based upon incidence of revision and change in Harris Hip Score and UCLA Rating. Safety will be measured by assessing all adverse events experienced by patients from study enrolment through to study completion.

Study Population
Description
Inclusion Criteria:
Subjects must meet all of the following characteristics for inclusion in the study.
- 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
Exclusion Criteria:
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)

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Revision for any reason
Time Frame: 10 years post-op
|
Implant survivorship at 10 years post study procedure.
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.
|
10 years post-op
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Patient Reported Outcome (PRO): Hip Disability and Osteoarthritis Outcome Score (HOOS)
Time Frame: 10 years post-op
|
The HOOS is developed as an instrument to assess the subject's opinion about their hip and associated problems. HOOS consists of 5 subscales: Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec), and hip related Quality of Life (QOL). Standardized answer options are given (5 Likert boxes) and each question gets a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale. |
10 years post-op
|
Patient Reported Outcome (PRO): modified Harris Hip Score (HHS)
Time Frame: 10 years post-op
|
Effectiveness assessed by comparison of changes in parameters from baseline through 10 year post. 2 subscales (8 items), Scores summed and normalized to 100, Excellent: 90 - 100 points Good: 80 - 89 points Fair: 70 - 79 points Poor: < 70 points.
|
10 years post-op
|
Patient Reported Outcome (PRO): University of California, Los Angeles (UCLA) rating
Time Frame: 10 years post-op
|
UCLA Activity Score is a measure of physical activity levels in subjects undergoing total joint arthroplasty.
The scale is from 1 - 10 with higher values indicating greater physical function.
|
10 years post-op
|
Safety Assessment
Time Frame: 10 years post-op
|
Safety will be measured by assessing all adverse events experienced by patients up to study completion or termination.
|
10 years post-op
