Figure 1


Fig. 1. A graphical representation of the optimized right knee joint center (KJC) observed from an anterior aspect. Planes 1 and 2 are defined by a point on the helical axis and the midpoint of the transepicondylar vector. The KJC is the average of the points on the helical axis intersected by planes 1 and 2. The distance between the transepicondylar vector and the helical axis in this figure is not to scale.
