In this paper lubrication and friction of normal and diseased knee joint has been introduced. Various surface roughness of articular cartilage have been determined during the gait cycle (stance
phase- swing phase) using squeeze film characteristics in knee joint, this paper aims to study the
effects friction and roughness on stride length for male and female during daily activities. The
mathematical model depends on the basis of the Stokes micro continuum theory, as well as we used
lubricant (Newtonian - non Newtonian) in case of non-Newtonian (micro-macro) roughness effect
has been studied and we compared effect film thickness of squeeze film lubrication in cycle time
and roughness on pressure film, load carry capacity, in the elderly and young people for each sexes.
