Introduction: Crosslinking of polyethylene has been known for decades to improve the abrasion resistance of the polymer for industrial applications. However, only three applications of this technology have been reported in use in total hip replacements in the orthopaedics literature by Grobbelaar et. al. [1], Oonishi et. al. [2], and Wroblewski et. al. [3]. Recently, the interest in highly cros...

Ultra-high molecular weight polyethylene (UHMWPE) is the most common bearing material in total joint arthroplasty due to its unique combination of superior mechanical properties and wear resistance over other polymers. A great deal of research in recent decades has focused on further improving its performances, in order to provide durable implants in young and active patients. From "historical"...

Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, thre...

Using PC-based on-line monitoring system, extensive measurements were performed in insulation blocks cut from the crosslinked polyethylene (XLPE) insulation of 36, 69 and 132 kV rated cables produced in Saudi Arabia. A needle-plane electrode system was used with a needle radius of 10 m. The role of 'applied voltage step-time duration' and associated time resolved initiation and growth of diffe...

Due to the increasing burden of revision in total knee arthroplasty (TKA), sustainable improvements in implant longevity may require the continued development of advanced bearing materials. The LEGIONTM Primary Knee System featuring VERILASTTM technology is the first device to combine an OXINIUMTM Oxidized Zirconium femoral component with a highly crosslinked ultra-high molecular weight polyeth...

The osmotic and scattering properties of hyaluronan-based composite hydrogels composed of stiff biopolymer chains (carboxymethylated thiolated hyaluronan (CMHA-S)) crosslinked by a flexible polymer (polyethylene glycol diacrylate (PEGDA)) are investigated and analyzed in terms of the scaling theory. The total pre-gel polymer weight concentration is varied between 0.5 wt.% and 3.2 wt.%, while th...
