Effect of Bearing Surface on Survival of Cementless and Hybrid Total Hip Arthroplasty

Abstract: Background: Modern bearing surface options have increased implant survivorship after total hip arthroplasty (THA). We utilized data from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR) to analyze implant survivorship after THAs with uncemented acetabular components with different bearing combinations. Methods: Polyethylene (PE) manufacturing properties supplied by the manufacturers were used to subdivide the NJR data set into c… Show more

“…In a recent study using data from the National Joint Registry of England and Wales, the CoC bearings had better survival compared to metal-on-poly (MoP) bearings but worse survival compared to ceramic-on-highly cross-linked polyethylene (CoXPE). The study however did not stratify analysis by the ceramic generation [25]. Further, the study also shows that the longevity of the prosthesis depends on the patient gender, age, head size, and stem xation.…”

“…Wear debris within a critical size range (~0.2–0.8 μm) has been shown to activate human macrophages and osteocytes which can result in a proinflammatory response, osteoclastogenisis and localized bone resorption or osteolysis 4–6 . Despite aseptic loosening being the leading cause of TJR failure to date, this complication has declined in prevalence since the introduction of highly wear resistant biomaterials (e.g., highly crosslinked and anti‐oxidant polymers) 7–9 . With approximately 58% and 82% of hip and knee replacements enduring 25 years of use, respectively, 10,11 understanding the characteristics and effects of wear debris remains essential for determining the long term performance of devices.…”
