In this work, a new finite element contact analysis approach allowing large sliding between articular cartilages is presented based on biphasic theory, an effective model for articular cartilage. The geometric constraint and continuous condition of fluid phase on contact surface are applied by introducing Lagrange multiplier. The formulation is carried out by transmitting the total contact pressure and hydrostatic pressure equivalently between contact surfaces and integrating virtual work due to contact over the contact area. The effectiveness of the proposed algorithm is verified by comparing numerical results with experimental ones of artificial articular cartilage.
