Does cross-linked polyethylene decrease the revision rate of total hip arthroplasty compared with conventional polyethylene? A meta-analysis

Orthopaedics and Traumatology: Surgery and Research, 2014
BackgroundAlthough cross-linked polyethylene is resistant to wear in comparison to conventional polyethylene, it remains unknown whether it can decrease the wear-related revision rate of total hip arthroplasty.ObjectivesTo determine whether cross-linked ...

Gel content determination in cross-linked polyethylene

Biomaterials, 1989
Gel content is the dominating parameter which affects properties and prescribes the behaviour of a given type of cross-linked polyethylene. Researchers have determined the gel content by several methods based on solvent extraction, a process which dissolves the linear thermoplastic polymer but swells only the cross-linked fraction.

Highly Cross-Linked Polyethylene Bearing

2021
Total hip arthroplasty (THA) is the most useful treatment in symptomatic patients with late-stage osteonecrosis of the femoral head (ONFH). Unique features of ONFH such as altered bone remodeling and high prevalence of younger patients may compromise the outcome after THA.

The Wear of Cross-Linked Polyethylene against Itself

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1996
Cross-linked polyethylene (XLPE) may have an application as a material for an all-plastic surface replacement finger joint. It is inexpensive, biocompatible and can be injection-moulded into the complex shapes that are found on the ends of the finger bones. Further, the cross-linking of polyethylene has significantly improved its mechanical properties.

A Double-Blind, Prospective, Randomized Controlled Trial Comparing Highly Cross-Linked and Conventional Polyethylene in Primary Total Hip Arthroplasty

Journal of Arthroplasty, 2009
Highly cross-linked polyethylene was developed to reduce articular bearing wear in total hip arthroplasty. In vitro studies have shown reduced wear in comparison with conventional polyethylene.

The Morphology of Cross-Linked Polyethylene Insulation

IEEE Transactions on Electrical Insulation, 1978
Cross-linked polyethylene, now commonly used for insulation of underground electric distribution cables, is susceptible to electrochemical treeing, in common with other polymeric dielectrics. This treeing phenomenon sometimes originates at holes or cavities present in the cable.

Hardness and creep of cross-linked polyethylene

Polymer, 1989
Abstract Vickers microhardness, tensile and compression tests and creep experiments have been performed at 22°C on electron beam irradiated high density polyethylene (HDPE). The microhardness and compression strengths were found to increase progressively with increasing dose in the range 0-500 kGy but the tensile strength was relatively constant. The

Multiple morphologies in cross-linked polyethylene

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1980, 1980
Here, a radial section of an uncross-linked miniature extruded cable was studied, the cable having been polished and cut in half, and then each half treated with one etchant. Both etchants revealed the spherulitic structure (Figure 1), much greater penetration having occurred in the case of the permanganic etchant.

Surface properties of cross-linked polyethylene

1998 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.98CH36257), 2002
This study reports on the loss of hydrophobicity of cross-linked polyethylene (XLPE) insulation. Specimens of steam cured XLPE cut from a nominal 28 kV/sub rms/ cable were immersed in saline solutions of varying conductivities from 5 to 10/sup 5/ /spl mu/S/cm over a wide range of temperatures from 0 to 98/spl deg/C.

Study on Cross-Linking Degree of Polyethylene

Advanced Materials Research, 2013
In this paper, the linear low density polyethylene (LLDPE) was melted and cross-linked by dicumyl peroxide (DCP) used to prepare cross-linked polyethylene (XPE). The gel content was determined by extraction method. The effect of content of cross-linker, cross- linked time, cross-linked temperature and other factors on the gel content were studied.
