The development of the 3R78 focused on a robust, dust-resistant design that is durable and resistant against environmental impacts.  This polycentric prosthetic knee joint with pneumatic swing phase control offers reliable stance phase security for users with moderate activity levels.

In the swing phase, the smooth yet powerful single chamber pneumatics (one chamber each for flexion and extension damping) does not run out of air, even at various walking speeds.  Smooth flexion and extension movements, and therefore an approximation of the physiological gait pattern, are made possible.  Here the joint geometry effectively shortens the prosthesis during swing through, resulting in more ground clearance.
