Polycentric Knee Joint with Pneumatic Swing Phase Control and Integrated Extension Assist Spring
Due to the polycentric technology, an especially large flexion angle is achieved. Furthermore, the alignment of the multiple axes provides a shortening of the prosthetic leg during swing phase adding to an increased safety against stumbling. The pneumatic swing phase control in combination with the dynamic performance of the joint linkage ensures a harmonic and natural gait pattern of the prosthesis wearer.
