Cu‐Enhanced Medium‐Entropy TiZrCoCrMo Alloys: Balancing Superior Antibacterial and Osteogenic Properties for Orthopedic Implants

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study introduces novel nonequiatomic TiZrCoCrMoCux (x = 0, 5, 10; at%) medium‐entropy alloys (MEAx) tailored for orthopedic implants, synergistically combining the biocompatibility of Ti‐based alloys, the wear resistance of CoCrMo alloys, and the antibacterial/osteogenic attributes of Cu. The alloy's microstructure, mechanical properties,

In Vivo Corrosion of Acetabular Modular Tapers Reduces Local Corrosion Resistance: Near‐Field Electrochemical Impedance Spectroscopy as an Indicator of the Type and Severity of Corrosion in Retrieved Hip Implants

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT Retrieved hip implant components experience a range of corrosion types and severity, often on small surface areas of the taper region. Tribocorrosion‐related damage within modular taper regions and resulting changes of the oxide‐covered surface can alter the local impedance of the interface.

In Vitro Evaluation of Hemiarthroplasty Bearing Materials: A Scoping Review (Part I)

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Hemiarthroplasty is used to treat joint damage confined to one side, aiming to preserve the remaining healthy cartilage and bone while addressing conditions like femur fractures and osteonecrosis; however, challenges persist due to cartilage wear and inconsistent clinical outcomes.

Electrostatically Assembled HA–DN/AMSN–TCS Coatings for Antibacterial Urinary Catheters

Biosurface and Biotribology, Volume 12, Issue 1, January/December 2026.
ABSTRACT Catheter‐associated urinary tract infections (CAUTIs) are a significant complication of indwelling urinary catheters, primarily caused by bacterial adhesion, biofilm formation and catheter‐induced mechanical irritation. To reduce the risk of infection and enhance catheter safety and performance, this study developed an antibacterial ...

Case Report: Pseudotumor due to Trunnionosis in Ceramic‐on‐Ceramic THA Monoblock Acetabular Cup Disengagement

Case Reports in Orthopedics, Volume 2026, Issue 1, 2026.
Adverse local tissue reaction (ALTR) and pseudotumor formation, representing inflammatory responses to wear debris that lead to osteolytic lesions, remain major long‐term complications of total hip replacement. Hard‐bearing total hip prostheses with improved tribological properties—particularly large‐diameter head (LDH) ceramic‐on‐ceramic (CoC ...

Tribocorrosion – Insight into Material Degradation in Specific Environments

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014
Tribocorrosion is an irreversible surface degradation mechanism of a metallic and/or non-metallic material as a result of its physicochemical and mechanical interactions during relative motion (friction, sliding, impact, abrasion, erosion) in corrosive ...

A Comparative Study on the Influence of Zirconia and Titanium Nanoparticles on the Functionality of Osteocytes In Vitro

International Journal of Dentistry, Volume 2026, Issue 1, 2026.
Introduction and Aim The aim of this study was to compare the influence of zirconia dioxide nanoparticles (ZrO2‐NPs) and titanium dioxide nanoparticles (TiO2‐NPs) on the functionality of osteocytes in vitro. Methods MLO‐Y4 osteocytic cells were treated with varying concentrations of ZrO2‐NPs or TiO2‐NPs for viability studies. Apoptosis assays following
