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 کاملA ruthenium catalyst yielding crosslinked polyethylene.
A ruthenium phosphane aryl sulfonate was found to be an efficient catalyst for the polymerization of ethene. Surprisingly, the resulting polyethylene is crosslinked.
متن کاملProperties of crosslinked ultra-high-molecular-weight polyethylene.
Substantially reducing the rate of generation of wear particles at the surfaces of ultra-high-molecular-weight polyethylene (UHMWPE) orthopedic implant bearing components, in vivo, is widely regarded as one of the most formidable challenges in modern arthroplasty. In the light of this, much research attention has been paid to the myriad of endogenous and exogenous factors that have been postula...
متن کاملMicrobial degradation of polyethylene glycols.
Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono- and tetraethylene glycols, but O2 consumption was not detectable when such cells were incubated for short per...
متن کاملMacrophage-mediated degradation of crosslinked collagen scaffolds.
Biological scaffolds used in tissue engineering are incorporated in vivo by a process of cellular in-growth, followed by host-mediated degradation and replacement of these scaffolds, in which phagocytic cells from the monocyte/macrophage cell lineage play a key role. The chemical degradation of scaffolds with collagenases is well established, but to date this has not been correlated with an in ...
