Össur®'s  RHEO KNEE®  3 provides the most natural knee function among all microprocessor knees because it continuously adapts to the user and the environment while providing perfect balance of stability and dynamics.

Effortless swing initiation enables a smoother gait, even in crowds and confined spaces
Advanced actuator and resistance control ensure best possible resistance, e.g. more support in stair descent and minimum effort needed in level ground gait
Constant power spring provides natural progression in swing
Five-sensor gait detection, including new gyroscope technology, ensures stability and dynamic response in every situation
Magnetorheologic technology enables an instant response so that users never have to wait for the knee to catch up with them

In the 10 years since the original RHEO KNEE made its debut, we've learned that the needs of low active users and more active users differ. Whereas low K3 users place a premium on stance stability, high K3 users desire a more responsive knee for a dynamic walking experience.
