Supercritical Solution Impregnation: A Strategy to Prevent Prosthetic Infections. [PDF]

Glob Chall
Infections following hip or knee replacement surgery are painful, difficult to treat, and often require additional operations. This study presents a sustainable carbon dioxide‐based method for loading antibiotics into prosthetic materials. These medicated prostheses prevent bacterial growth without altering implant properties, potentially reducing ...

Arthroscopic All-Inside/All-Suture Repair of Complete Radial Tear of the Lateral Meniscus Using a Percutaneous Single-Needle Technique. [PDF]

Arthrosc Tech
Abstract Radial tears of the lateral meniscus have limited healing potential and unfavorable biomechanics, and current suture constructs that use capsular rip‐stop stitches may increase meniscal extrusion and constrain native motion. This technical note describes an all‐inside, crossed, meniscus‐based repair for complete or near‐complete radial tears ...

Do the particle size, molecular weight, and processing of UHMWPE affect its thermomechanical and tribological performance?

Journal of Materials Research and Technology, 2021
UHMWPE has exhibited excellent performance when used as contact surfaces in tribological contacts. Traditionally, only UHMWPE grades, with narrow particle size and molecular weight distribution, have been deemed suitable for such applications.

Synthesis and Tribological Behavior of Ultra High Molecular Weight Polyethylene (UHMWPE)-Lignin Composites

Lubricants, 2016
In this paper, we report the synthesis and characterization of ultra-high molecular weight polyethylene (UHMWPE)-lignin composites. During this study four different compositions, namely UHMWPE, UHMWPE-13 wt. % lignin, UHMWPE-25 wt. % lignin and UHMWPE-42.

Rheological and mechanical properties of ultrahigh molecular weight polyethylene/high density polyethylene/polyethylene glycol blends

Advanced Industrial and Engineering Polymer Research, 2019
Ultra-high molecular weight polyethylene (UHMWPE) possesses many excellent properties, but poor processability. There are many ways to improve the processability of UHMWPE, but most of which will compromise its other outstanding properties. The effect of

Porous titanium layer co-immobilized with bone morphogenetic protein-2 and vancomycin for biofunctionalization of ultra high molecular weight polyethylene

Materials & Design, 2023
Ultra high molecular weight polyethylene (UHMWPE), a common material for artificial joint linings, lacks appropriate bioactivity and antibacterial property, which could lead to prosthetic loosening and infections after surgery.

Recent Advances of Mechanical Performance and Oxidation Stability in Ultrahigh Molecular Weight Polyethylene for Total Joint Replacement: Highly Crosslinked and α-Tocopherol Doped

Journal of Biomechanical Science and Engineering, 2006
Ultrahigh molecular weight polyethylene (UHMWPE) is the popular material of choice for use as a bearing surface in total joint replacement (TJR). Despite an extremely low friction coefficient of UHMWPE to metals with liquid lubrication, however, wear and

Effect of carbon-based antistatic agent on properties of ultra-high molecular weight polyethylene

You-qi chuyun, 2022
Polymer lining material has a bright application prospect to improve the corrosion resistance of metal oil and gas pipelines in service, but its further popularization and application is constrained by the poor antistatic property.

Predicting implant UHMWPE wear in-silico: A robust, adaptable computational-numerical framework for future theoretical models [PDF]

, 2011
Computational methods for the pre-clinical wear prediction for devices such as hip, knee or spinal implants are valuable both to industry and academia. Archard’s wear model laid the basis for the first generation of theoretical wear estimation algorithms,
