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 کاملVivacit-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...
متن کاملCorrelation Between In Vivo Oxidation and Mechanical Properties In Contemporary Polyethylene Bearings
Introduction: Ultra-high molecular weight polyethylene oxidation remains an important concern in total joint arthroplasty, since it eventually results in a significant drop in mechanical properties that may compromise implant longevity, especially for TKA [1-3]. In vivo oxidation of polyethylene can occur in the presence of unstabilized macroradicals within the polymer and molecular oxygen upta...
متن کاملAn experimental approach to determining fatigue crack size in polyethylene tibial inserts.
A major limiting factor to the longevity of prosthetic knee joints is fatigue crack damage of the polyethylene tibial insert. Existing methods to quantify fatigue crack damage have several shortcomings, including limited resolution, destructive testing approach, and high cost. We propose an alternative fatigue crack damage visualization and measurement method that addresses the shortcomings of ...
متن کاملFracture of Two Moderately Cross-Linked Polyethylene Tibial Inserts in a TKR Patient
Highly cross-linked polyethylene has become the gold standard in total hip replacement for its wear resistance. Moderately crosslinked polyethylene is now available for total knee replacement (TKR), although concerns about reduced mechanical strength have prevented widespread adoption. The purpose of this report is to describe an unusual case where a patient underwent cruciate retaining TKR usi...
