Biomechanical analysis demonstrates low likelihood of full-film lubrication via sliding in human joints, highlighting squeeze film action during brief loading.
Recent developments in the analysis of elastohydrodynamic lubrication (EHL) of solids covered by soft layers, are applied to the big load-bearing human joints. It is concluded that the chances of generating a full film by conventional rolling/sliding EHL are small; but for loads of short duration the squeeze film mechanism looks very promising.
