6H25ST Polycentric pneumatic knee module

The knee module is designed for patients with medium to high activity level, unilateral or bilateral femoral amputation at any level, including disarticulation, weight not exceeding 125kg. The knee module has separate adjustments for flexion/extension and hamstring resistance. It allows walking at a speed of up to 6 km/h. The polycentric design of the knee module allows shortening of the prosthesis during the transfer phase. The geometric closure in the knee module ensures absolute safety in the support phase. The knee module is only released during toe-off at the end of the support phase.
