原始语种摘要: Abstract(#br)Immunological response induced by wear particles of ultra-high molecular weight polyethylene (UHMWPE) has been recognized as the major factor causing the failure of total joint replacements. A previous study has applied surface texturing techniques to generate UHMWPE wear particles with specific size and shape to study the effects of particle size and shape on osteolysis.(#br)In the present study, the effects of biological lubricants on the morphology of UHMWPE wear particles generated with microfabricated surface textures were investigated. It was observed that UHMWPE wear particles generated in bovine serum are smaller and thinner than the particles generated in water. The reason may be due to the reduction of the friction between UHMWPE and the surface feature under serum...
