Fabrication of modified ultra-high molecular weight polyethylene via hybrid approaches for next-generation biomedical implants [PDF]

Exploration of BioMat-X
Ultra-high molecular weight polyethylene (UHMWPE) is widely used as a key material in biomedical implants such as artificial joints due to its exceptional wear resistance, high impact strength, and good biocompatibility.

Characterization of the Fatigue Threshold Behavior of Uhmwpe

Journal of the Mechanical Behavior of Biomedical Materials
Ultra-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.

Reduction of Wear Volume from Accelerated Aged UHMWPE Knee Components by the Addition of Vitamin E

Journal of Biomechanical Science and Engineering, 2009
Accelerated ageing was conducted on UHMWPE with and without vitamin E (D, L-α tocopherol, VE). Wear performance was investigated using a knee simulator and wear debris was analysed.

Natural Polyphenols Enhance Stability of Crosslinked UHMWPE for Joint Implants

, 2015
Radiation-crosslinked UHMWPE has been used for joint implants since the 1990s. Postirradiation remelting enhances oxidative stability, but with some loss in strength and toughness.
