Cross-linked versus conventional polyethylene for total hip replacement: a meta-analysis of randomised controlled trials.
We conducted a systematic review and meta-analysis of randomised controlled trials comparing cross-linked with conventional polyethylene liners for total hip replacement in order to determine whether these liners reduce rates of wear, radiological evidence of osteolysis and the need for revision. The MEDLINE, EMBASE and COCHRANE databases were searched from their inception to May 2010 for all t...
متن کاملHighly Cross-Linked Polyethylene in Total Hip and Knee Replacement: Spatial Distribution of Molecular Orientation and Shape Recovery Behavior
The present study investigated effects of processing procedures on morphology of highly cross-linked and re-melted UHMWPE (XLPE) in total hip and knee arthroplasty (THA, TKA). The shape recovery behavior was also monitored via uniaxial compression test at room temperature after non-destructive characterizations of the in-depth microstructure by confocal/polarized Raman spectroscopy. The goal of...
متن کامل[Polyethylene particles in synovial fluid after knee arthroplasty with a conventional or highly cross-linked polyethylene. Preliminary study].
AIM OF THE STUDY In recent years cross-linked polyethylenes have been developed in an attempt to reduce the wear, as has been demonstrated in knee simulators. The aim is to assess, by counting particles of polyethylene in synovial fluid, whether the reduction in wear is confirmed in patients with a highly crosslinked polyethylene prosthesis. MATERIAL AND METHODS A prospective randomised study...
متن کاملWear Analysis of Second-generation Highly Cross-Linked Polyethylene in Primary Total Hip Arthroplasty.
A major limiting factor in the longevity of total hip replacement is the wear rate of the hip bearing. As manufacturing technology has improved during the past several decades, much attention has been focused on developing newer generations of polyethylene that have lower rates of wear while minimizing free radical formation and subsequent osteolysis. The turning point for the manufacture of po...
متن کاملReduction of Total Knee Replacement Wear with Vitamin E doped highly cross linked UHMWPE
Introduction: Ultra high molecular weight polyethylene (UHMWPE) is a common bearing component in Total Knee Replacement (TKR) implants, and its susceptibility to wear continues to be the long-term limiting factor in the life of these implants. Novel material modifications have been introduced to reduce UHMWPE wear rates and thus improve the life of TKRs. Radiation and crosslinking of UHMWPE hav...
