Figure 4.5. Tibiofemoral compression force as a function of flexion angle
The incorporation of the moving center of gravity (the forward and backward movement of the
trunk) is an absolute novelty among the existing analytical models. The former analytical
models were mainly validated by Oxford test rigs [Singerman et al., 1999, Petersilge et al.,
1994, Churchill et al., 2001] that had load systems similar to the standard squat model in
Figure 2.38, which permits the center of gravity to move only vertically under squat movement.
This restriction prevents us to observe how the patello- and tibiofemoral forces change with the
moving center of gravity.
