The results of shear stress and compressive stress on the femoral cartilage, meniscus and tibial cartilage under static stance simulation. Tsf: tresca stress (shear stress) of the femoral cartilage; Tsm: tresca stress(shear stress) of the meniscus; Tst: tresca stress (shear stress) of the tibial cartilage; Mpsf: minimum principal stress of the femoral cartilage; Mpsm: minimum principal stress of the meniscus; Mpst: minimum principal stress of the tibial cartilage
