Polycentric knee joint 4 axis

SKU: 6H09A Categories: ,

The 6Н09А knee is for patients with low and moderate activity levels. The knee is used in prostheses for amputation above the knee (transfemoral amputation).
The needle roller bearings used in manufacture increase knee stability and trustworthiness during use. Said module’s kinematics allow for a functional reduction of the prosthesis of up to 15 mm in the forward movement phase of the support surface, thereby obtaining a prosthesis identical in length to the other member. The knee is equipped with an adjustable device to extend the knee.
