Osteoarthritis and Cartilage Biotribology

, 2022
Osteoarthritis (OA) involves deterioration of cartilage, including enzymatic degradation and mechanical damage, resulting in disruption of cartilage lubrication, which in turn gives rise to the progressive deterioration in the structure and function of the cartilage tissue.

Effect of dynamic loading versus static loading on the frictional behavior of a UHMWPE pin in artificial biolubricants

Biosurface and Biotribology, 2017
To obtain reliable results from in vitro measurements on the tribological behavior of joint implant materials, the parameters of the measurements must simulate in vivo conditions.
