Rheo Knee

RHEO KNEE is an advanced prosthetic device for transfemoral amputees which continuously adapts to an amputee's walking style and environment.

The freedom to move confidently with an above knee prosthetic leg

RHEO Knee® is a vital part of an above knee prosthetic leg and seamlessly detects your movements so you can walk naturally and effortlessly ⁠— even on difficult terrain.

The RHEO Knee's microprocessor-controlled system learns how you move, adapting automatically so you can easily navigate slopes, stairs, tight spaces, or a brisk pace with confidence. The microprocessor knee is designed for a variety of users and circumstances delivering confidence-boosting stability and a dynamic experience for users who want to get the most out of their above knee prosthetic leg.
RHEO Knee® has been designed using specialist technology that ensures the microprocessor knee is capable of shifting almost instantaneously from the high resistance needed when standing, to the zero resistance required for the dynamic free swing whilst walking.

The 'zero-lag' experience simulates the natural function of the physiological knee joint and produces a fast, accurate response to changes in speed, direction and terrain without the need to select a specific mode. This means that you can trust your above knee prosthetic leg to adapt to you and your surroundings automatically.
