Abstract :
This study analyzes the frictional properties of ultra high molecular weight polyethylene tibial surfaces in various loading and fluid environments. A tibial slider was designed to simulate the tibial implant movement on the femoral implant surface in order to determine coefficient of friction. Finite element analysis is used to further analyze the stresses in the implants in various conditions and loading
