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 ...

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 ...

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.

Dry And Ringer Solution Lubricated Tribology Of Thin Osseoconductive Metal Oxides And Diamond-Like Carbon Films

Archives of Metallurgy and Materials, 2015
Achieving fast and strong adhesion to jawbone is essential for dental implants. Thin deposited films may improve osseointegration, but they are prone to cohesive and adhesive fracture due to high stresses while screwing the implant into the bone, leading
