Post-Approval Study of the R3 Biolox Delta Ceramic Acetabular System - Europe (R3 EU PAS)

May 28, 2024 updated by: Smith & Nephew Orthopaedics AG
The purpose of this prospective, multicenter, single arm study is to confirm the long-term safety and effectiveness of the R3 delta Ceramic Acetabular System PMA (P150030) by evaluating long-term (10 years after surgery) follow-up results.

Detailed Description

This PAS is a long-term follow-up of the R3 delta Ceramic Acetabular System (DOD) hips enrolled in the study that was analyzed for the Premarket Approval Application (PMA) Study. The PMA Study analyzed 3 Year postoperative follow-up data on Biolox delta ceramic-on-Biolox delta ceramic (DOD) and Oxidized zirconium-on-Crosslinked Polyethylene (OxZr/XLPE) hips, enrolled and followed in a European Post-market Study ("A prospective, multicenter, non-randomized, clinical outcome study of the R3 Acetabular System in patients with degenerative hip disease").

The purpose of this prospective, multicenter, single arm study is to confirm the long-term safety and effectiveness of the R3 delta Ceramic Acetabular System PMA (P150030) by evaluating long-term (10 years after surgery) follow-up results. Hips are evaluated at the following intervals: 5, 7, 10 years postoperative. The primary study endpoint is implant survivorship at 10 years post surgery.

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.

Description

Inclusion Criteria:

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/ developmental dysplasia of the hip) 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:

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)

Cohorts and Interventions

Group / Cohort
Post Approval Study

The PAS cohort consisted of 137 subjects who were implanted with the R3 delta Ceramic Acetabular System (DoD) in the pivotal study. These patients will continue to be followed to 10 years post-operatively.

The primary endpoint for the PAS study is implant survivorship at 10 years post study procedure.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Implant Survivorship
Time Frame: 10 Years
Number of participants hip implant survivorship with implant survival defined as no revision through 10 years (i.e., 'Hip Survived' or 'Hip Did Not Survive').
10 Years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modified Harris Hip Score (mHHS)
Time Frame: Pre-operative, 3-years, 5-years, 7-years, 10-years
The mHHS scoring assessment ranges from 0 (worst) to 100 (best). Scores assessed during the pre-operative, 3-year, 5-year, 7-year and 10-year visit.
Pre-operative, 3-years, 5-years, 7-years, 10-years
Number of Participants With Radiographic Success
Time Frame: 3-years, 5-years, 7-years 10-years

Count of participants with radiographic success, where success is defined as:

  • No radiolucencies greater than 2 mm in 50% or more in any of the cup or stem zones; and
  • No femoral or acetabular subsidence greater than or equal to 5mm from baseline; and
  • No acetabular cup inclination changes greater than 4 degrees (4°)

Participants who did not meet criteria specified above were considered radiographic failures

3-years, 5-years, 7-years 10-years
