Sensor Knee

The Sensor Knee utilises a sophisticated hydraulic system that can be adapted to suit any amputee – from the first stages of rehabilitation right through to optimum ability and high activity use.

Sensor’s hydraulic system is weight-activated, providing maximum security, and allowing the amputee to walk smoothly and naturally. The knee also features both stance lock and activated stance yield modes. Its weight-activated locking mode ensures maximum security and protection, and its stance yield function permits safe and easy travel over uneven areas, and down slopes or stairs leg over leg.
