## Abstract After total hip arthroplasty (THA), polyethylene acetabular liner creep occurs quickly and serves to increases headβliner contact area and decrease contact pressures. What effect these early changes in contact mechanics will have on the wear behavior of the articulation remains unclear,

β¦ Synopsis
The role that ultrahigh molecular weight polyethylene (UHMWPE) wear at bearing surfaces in total hip and knee arthroplasties plays in the clinical life of these implants cannot be overemphasized. This subject has therefore been attracting enormous research attention on both fundamental and technological levels. Given this, it is important to detail the main features of the knowledge base and describe research directions that may culminate in the production of new and/or improved varieties of UHMWPE material and components. These aspects are the subject of the present review.

## Abstract Adaptive remeshing capability was addded to an existing slidingβdistanceβcoupled finite element model of polyethylene wear in total hip arthroplasty. This augmentation allowed earlier postoperative wear simulation to be extended to the clinically more significant longβterm regimen (as l
## Abstract Reduction of wear with highly crosslinked polyethylene (HXLPE) has been reported in __in vitro__ and __in vivo__ studies of total hip prostheses. However, use of HXLPE in total knee prostheses is still controversial. The aim of this study was to compare __in vivo__ polyethylene wear par
## Abstract Polyethylene wear particles are one of the most important factors affecting the results of total hip arthroplasty (THA). To reduce wear generation and to achieve better longβterm results of THA, highly crosslinked polyethylene (HXPE) has recently been introduced and come into wide use.
