Four-bar pneumatic prosthetic knee joint is made of aviation grade ultra-light, super-hard magnesium alloy material, with
beautiful appearance. The weight was 0.95kg, the maximum load was 125kg, and the knee flexion was 150 degrees.

This multi-centered prosthetic knee joint with pneumatic swing phase control provides reliable standing phase safety for users
with moderate activity levels.
The smooth and powerful single-chamber pneumatics (each chamber for flexion and extension damping) does not run out of air during
the swing phase, even at different walking speeds. Smooth flexion and extension movements can be achieved, resulting in an
approximation of the physiological gait pattern. The prosthetic knee joint geometry here effectively shortens the prosthesis
during oscillation, thereby increasing ground clearance.
