Tribological Characteristics of Al2O3 Nanocomposites for Joint Prostheses

Journal of Biomechanical Science and Engineering, 2008
In this study the tribological characteristics of a sliding pair of Al2O3 nanocomposites against Al2O3 were investigated. Al2O3 nanocomposites are proposed as a candidate material for the fabrication of prostheses.

In Vitro Wear Testing of a CoCr-UHMWPE Finger Prosthesis with Hydroxyapatite Coated CoCr Stems

Lubricants, 2015
A finger prosthesis consisting of a Cobalt-chromium (CoCr) proximal component and an Ultra-high-molecular-weight-polyethylene (UHMWPE) medial component (both mounted on hydroxyapatite coated stems) was evaluated to 5,000,000 cycles in an in vitro finger ...

Ti3C2T x ‐UHMWPE Nanocomposites—Towards an Enhanced Wear‐Resistance of Biomedical Implants

Journal of Biomedical Materials Research Part A, Volume 113, Issue 1, January 2025.
Polymeric biomedical materials, notably UHMWPE in load‐bearing joints, lack optimal mechanical and biotribological properties. This study aims to enhance Ti3C2T x ‐UHMWPE nanocomposites, improving mechanical strength, biocompatibility, and biotribological performance. Tests reveal no adverse effects on hardness, elasticity, or cytotoxicity.

Influence of Neutral and Cationic Phytoglycogen Nanoparticles on Cartilage and Ocular Lubrication

Biosurface and Biotribology, Volume 11, Issue 1, January/December 2025.
ABSTRACT Compromised hydration and biolubrication leads to untreatable disorders like osteoarthritis (OA), dry eye disease (DED) and dry mouth disease (xerostomia). Only symptomatic treatment is possible through bioactive molecules. This study aims to investigate the biolubrication properties of natural and modified phytoglycogen nanoparticles (PGNPs ...

Role of protein concentration on transient film thickness in synovial fluid lubricated joints [PDF]

, 2021
A computational model of protein aggregation lubrication has been developed for predicting transient behaviour in lubricated prosthetics. The model uses an advection-diffusion equation to simulate protein transport in order to map concentration changes ...

Biotribology of artificial hip joints

World Journal of Orthopedics, 2015
Hip arthroplasty can be considered one of the major successes of orthopedic surgery, with more than 350000 replacements performed every year in the United States with a constantly increasing rate. The main limitations to the lifespan of these devices are due to tribological aspects, in particular the wear of mating surfaces, which implies a loss of ...
