Combined Effects of Polyethylene Wear Particle Size and Dosage on Macrophage Responses
, 2011 Ultrahigh molecular weight polyethylene (UHMWPE) wear particles-induced osteolysis and aseptic loosening is the main reason causing the failure of the total joint replacement. It is believed that cytokines, such as tumor necrosis factor-alpha (TNF-alpha),

Characterization of the Fatigue Threshold Behavior of Uhmwpe
Journal of the Mechanical Behavior of Biomedical MaterialsUltra-high-molecular-weight-polyethylene (UHMWPE) has been the material of choice for bearings in total joint replacements (TJRs) for decades as a result of its excellent wear resistance, chemical inertness, energetic toughness, low friction, and biocompatibility.

Advanced Science, Volume 13, Issue 36, 29 June 2026.We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...

Tribological Studies of Modem orthopaedic biomaterial Combinations [PDF]
, 2005 Debris created during the wear of prosthetic joints is known to have an effect on the success of the implant. As such the factors affecting wear and lubrication need to be understood in order to reduce wear as much as possible in vivo.

Orthopaedic Journal of Sports Medicine, 2019 Background: Transtibial pull-out repair of the medial meniscal posterior root (MMPR) has been largely assessed through biomechanical studies. Biomechanically comparing different suture types would further optimize MMPR fixation and affect clinical care ...

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.Hybrid composite shape memory scaffolds were developed for potential craniomaxillofacial bone defect repair. These scaffolds exhibit accelerated degradation and induce rapid, robust hydroxyapatite mineralization in 1X simulated body fluid (SBF). ABSTRACT “Self‐fitting” shape memory polymer (SMP) scaffolds based on cross‐linked poly(ε‐caprolactone ...
