Massive Osteolysis in a Modern Total Knee Prosthesis

Case Reports in Orthopedics, 2021
Case. An 82-year-old woman underwent right total knee replacement with a sequentially irradiated and annealed highly cross-linked polyethylene insert. At 9 years, she was found to have a massive femoral osteolysis with an impending fracture.

Early failure of sequentially annealed polyethylene in total knee arthroplasty

Arthroplasty Today, 2020
Improvements in the processing of polyethylene have led to a dramatic reduction in wear rates in total hip arthroplasty. This led to the adoption of modern highly cross-linked polyethylene in total knee arthroplasty (TKA).

Correlations between physico-chemical properties and dielectric behavior of thermally aged XLPE cables insulation

ENP Engineering Science Journal, 2022
The carried out investigations aim at clarifying the correlations between physico-chemical properties and the variation of dielectric losses of Cross-Linked Polyethylene (XLPE) as Medium Voltage cable insulation during thermal aging. The used cables were

Wear, bone density, functional outcome and survival in vitamin E-incorporated polyethylene cups in reversed hybrid total hip arthroplasty: design of a randomized controlled trial

BMC Musculoskeletal Disorders, 2012
Background Aseptic loosening of total hip arthroplasties is generally caused by periprosthetic bone resorption due to tissue reactions on polyethylene wear particles.

Mobility‐limited charge injection in cross‐linked polyethylene under extra high electric field

High Voltage, 2021
In this study, characteristics of charge injection under extra high electric field (above 100 kV/mm) in cross‐linked polyethylene (XLPE) were investigated by experiments of conduction current and space charge.

Incarcerated fracture fragments of Longevity polyethylene liners after total hip arthroplasty

Arthroplasty Today, 2016
Highly cross-linked polyethylene liners are widely used in total hip arthroplasty because they experience lower wear rates than conventional polyethylene liners.

High survivorship of highly cross-linked polyethylene in revision Total hip Arthroplasty: a minimum 10-year follow-up study

Arthroplasty, 2019
Purpose Highly cross-linked polyethylene has been introduced to decrease osteolysis secondary to polyethylene wear debris generation. However, few long-term data on revision total hip arthroplasty (THA) using highly cross-linked polyethylene liners are ...

Correlation Between Thermal Parameters and Morphology of Cross-Linked Polyethylene

IEEE Access, 2020
This paper reveals a correlation between morphology and thermal parameters on cross-linked polyethylene (XLPE) cable with different insulating states. Several cables were selected to detect the physicochemical and thermal parameters of the XLPE.

Remaining lifespan prediction of cross‐linked polyethylene material based on GM(1, N) grey models

IET Generation, Transmission & Distribution, 2022
Cross‐linked polyethylene (XLPE) cables are a critical component of power transmission systems. As operating conditions sometimes exceed the thresholds set in discipline, some cables fail to reach their designed lifespan, and consequently evaluating the ...

Micro X-Ray Computed Tomography Mass Loss Assessment of Different UHMWPE: A Hip Joint Simulator Study on Standard vs. Cross-Linked Polyethylene. [PDF]

PLoS ONE, 2017
More than 60.000 hip arthroplasty are performed every year in Italy. Although Ultra-High-Molecular-Weight-Polyethylene remains the most used material as acetabular cup, wear of this material induces over time in vivo a foreign-body response and ...
