Fig. 7

Peak and mean contact pressure as a function of knee flexion angle are illustrated for both the healthy knee model (FE calculation) and values reported by Powers et al. [33]. The “healthy knee” model in the current study consistently predicted significantly higher peak pressure values (1.97 MPa (SD 0.16 MPa) vs. 1.44 MPa (SD 0.21 MPa), p = 0.007) and slightly higher mean pressure values (0.79 MPa (SD 0.05 MPa) vs. 0.66 MPa (SD 0.02 MPa), p = 0.054)
