Vitamin e-stabilized highly cross-linked polyethylene for improved mechanical strength

Clinical Value Dossier for Longevity Highly Cross-linked Polyethylene

Five-Year Experience of Vitamin E-Diffused Highly Cross-Linked Polyethylene Wear in Total Hip Arthroplasty Assessed by Radiostereometric Analysis.

BACKGROUND Vitamin E-diffused highly cross-linked polyethylene (VEPE) was developed to reduce oxidation without compromising mechanical strength. The purpose of this study was to evaluate VEPE in vivo using radiostereometric analysis (RSA) and patient-reported outcome measures (PROMs). METHODS Fifty-one hips were enrolled. Each patient received a VEPE liner, a porous titanium shell, and an un...

Microstructure, thermooxidation and mechanical behavior of a novel highly linear, vitamin E stabilized, UHMWPE.

A novel, vitamin E-stabilized, medical grade ultra-high molecular polyethylene, MG003 (DSM Biomedical; The Netherlands), has been very recently introduced for use in total joint replacements. This homopolymer resin features average molecular weight similar to that of conventional GUR 1050 resin (5.5-6*10(6)g/mol), but a higher degree of linearity. The aim of this study was to characterize the m...

Vivacit-E® Vitamin E Highly Crosslinked Polyethylene Long-term Performance For High Demand Patients

Total joint replacement is being performed on younger patients who expect to remain active throughout their lifetime, and as such this demographic shift has created a need for long-term implant bearing performance. First introduced in the 1990s, highly crosslinked polyethylene (HXPE) has demonstrated promising wear properties through the first decade of in vivo use. Recent studies, however, hav...

Cross-linked Polyethylene Engineered for TKA

Introduction It is well known that the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) improves in proportion to the crosslinking irradiation dose. It is also well known that the mechanical properties and oxidative stability of UHMWPE are affected by the irradiation dose, resin type, and post-irradiation heat treatment, among others factors. Therefore, careful consideration...
