Wear of highly crosslinked polyethylene acetabular components
BACKGROUND AND PURPOSE Wear rates of highly crosslinked polyethylene (XLPE) acetabular components have varied considerably between different published studies. This variation is in part due to the different techniques used to measure wear and to the errors inherent in measuring the relatively low amounts of wear in XLPE bearings. We undertook a scoping review of studies that have examined the i...
متن کاملWear of Highly Cross-linked Polyethylene against Cobalt Chrome and Ceramic Femoral Heads
+*Jennings, L M; *Galvin, A L; *Fisher J +Institute of Medical & Biological Engineering, Leeds, UK [email protected] Introduction There is increasing interest in the coupling of highly cross-linked polyethylene with large diameter heads in the hip, due to the reported lower wear characteristics of highly cross-linked polyethylene compared to conventional polyethylene [1, 2, 3]. Further, ...
متن کاملPotential for adhesive wear in friction couples of UHMWPE running against oxidized zirconium, titanium nitride coatings, and cobalt-chromium alloys.
The classical wear mechanisms abrasion, fatigue, and adhesion are the most frequent causes of surface changes of ultra high molecular weight polyethylene (UHMWPE) in artificial joints. The counterpart material has a strong influence on the wear and friction behavior of artificial joints due to its abrasive properties and adhesive interaction with UHMWPE. The formation of a transfer layer on the...
متن کاملFive-year comparison of oxidized zirconium and cobalt-chromium femoral components in total knee arthroplasty: a randomized controlled trial.
BACKGROUND In vitro analysis has shown that oxidized zirconium on ultra-high molecular weight polyethylene has better wear properties than cobalt-chromium on ultra-high molecular weight polyethylene. The purpose of this study was to determine if oxidized zirconium femoral components performed better than cobalt-chromium in vivo and if the use of oxidized zirconium components had clinical advers...
