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 ...

Finger pad friction and tactile perception of laser treated, stamped and cold rolled micro-structured stainless steel sheet surfaces

Friction, 2017
Tactile perception is a complex system, which depends on frictional interactions between skin and counter-body. The contact mechanics of tactile friction is governed by many factors such as the state and properties of skin and counter-body.

Machine learning‐based investigations of the effect of surface texture geometry on the wear behaviour of UHMWPE bearings in hip joint implants

Biosurface and Biotribology, Volume 10, Issue 4, Page 143-158, November 2024.
Abstract The purpose of this research is to develop data‐driven machine learning (ML) models capable of estimating the specific wear rate of ultra‐high molecular weight polyethylene (UHMWPE) used in hip replacement implants. The results of the data‐driven models are demonstrating a high level of consistency with the experimental findings acquired from ...

The development of a small-scale wear test for CoCrMo specimens with human synovial fluid [PDF]

, 2018
A new test was developed to measure friction and wear of hip implant materials under reciprocating sliding conditions. The method requires a very small amount of lubricant (

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 ...

Injectable Boron Nitride‐Hyaluronic Acid Hybrid Hydrogels to Facilitate Joint Motion: Mechanical and Tribological Characterization

Advanced Therapeutics, Volume 7, Issue 10, October 2024.
The lubricating property of hexagonal boron nitride (hBN) is used for the first time to facilitate joint mobility. The effect of increasing the addition of nanoparticle (BNPs) and nanosheet (BNNSs) structures on the CoF is discussed. BNNS doped hydrogel showed an 18.9% decrease in CoF compared to untreated hydrogel.

Biotribology Behavior of Ultra-High Molecular Weight Polyethylene against Carbon/Carbon Composites Used for Hip Joint Replacement

, 2011
In order to investigate the biotribology behavior of a novel artificial joint pair composed of a carbon/carbon composite femoral head and an ultra-high molecular weight polyethylene (UHMWPE) acetabular cup, a hip joint simulator was employed to predict ...

EFFECT OF HYALURONIC ACID MOLECULAR WEIGHT ON FRICTION OF ARTICULAR CARTILAGE [PDF]

Proceedings on Engineering Sciences, 2019
Hyaluronic acid (HA) is among others one of the component of synovial fluid (SF) and is the main component which affects the rheology of SF. However, during various degenerative joint diseases like osteoarthritis, the concentration and molecular weight ...
