Polycentric Disarticulation Knee Joint | PR04.DZ.16S

Disarticulation knee joint with polycentric kinematics that offers excellent stability and comfort for the prosthetic limb user.

The polycentric knee, also referred to as “fourbar” knee allows stance phase control through its polycentric axis. At the same time it is easy to bend to initiate the swing phase or to sit down. Another important feature of the polycentric knee is that the length of the leg shortens when a step is taken, reducing the risk of stumbling.

The Polycentric Knee is suitable for a wide range of patients, including those with mobility grade 2 who cannot walk securely with other types of knees, have a bilateral leg amputation or a long residual limb.
