The Exeter Contemporary flanged cemented acetabular component in primary total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Clinical Outcomes Research

Background:

• Total hip arthroplasty (THA) is a common procedure for hip osteoarthritis.
• The Exeter Contemporary flanged cemented acetabular component is a widely used implant.
• Long-term survivorship data for this specific component are essential for clinical decision-making.

Purpose of the Study:

• To evaluate the clinical outcomes and survivorship of the Exeter Contemporary flanged cemented all-polyethylene acetabular component.
• To assess the rate of revision and identify reasons for failure at a minimum 10-year follow-up.

Main Methods:

• Retrospective review of 203 primary cemented THA cases using the Exeter Contemporary acetabular component.
• Analysis of clinical outcome scores (Oxford and Harris hip scores) and radiographic data.
• Kaplan-Meier survivorship analysis with revision for aseptic loosening as the primary endpoint.

Main Results:

• No acetabular component revisions were required for aseptic loosening.
• Overall survivorship at 12.5 years was 97.8% for all causes of revision.
• Significant improvements in Oxford and Harris hip scores were observed (p < 0.001).
• Radiolucent lines were present in 36% of evaluated components, primarily in zone 1, with no component migration.

Conclusions:

• The Exeter Contemporary flanged cemented acetabular component demonstrates excellent survivorship and clinical efficacy.
• The component shows a low rate of revision, even when used with the Exeter stem in THA.
• These findings support the long-term reliability of this acetabular component in primary cemented THA.
