Some of these criteria include the orientation and position of the leg, the leg-shortening effect, the centrode shape, and the position of the ICR (instantaneous centre of rotation).
Since the prosthetic knee should mimic the natural biomechanics of the knee, including the centrode shape and the leg-shortening effect, a polycentric-type mechanism is proposed because of its superior kinematic capabilities than a hinge-type mechanism [18, 36, 38].
During the cutting process, the instantaneous center P forms the moving centrode relative to the driven link CDG and the fixed centrode relative to the fixed frame, represented by curves [[GAMMA].sub.1] and [[GAMMA].sub.2], as displayed in Figure 5.
As the velocity of instantaneous velocity center P at any moment in the fixed coordinate system H - xy is zero, namely, [mathematical expression not reproducible] by arranging and rewriting the above equation, the moving centrode of link CDG is expressed as
By solving this equation the coordinates of non-mobile centrode are determined in the non-mobile coordinate system and variable angular velocity of the spindle
Coordinates of instantaneous velocities centre P and nonmobile centrode graph are not dependant on the selection of points [O.sub.1] and [O.sub.2] and also from their position according to the axis of the spindle.

In comparison, with a centrode type mechanism there is a infinite number of precision points/positions which can be imposed.
The research is important because, with this analysis method, and with existing synthesis methods(Lovasz, 2000), centrode type mechanisms can be designed and used where 5 precision points/positions are not sufficient in order to obtain an optimal solution.
