POWERKNEE- OSSUR

 The Power Knee is the world’s first motor-powered microprocessor knee. Active assistance powers flexion and extension to mimic concentric 
and eccentric muscle activity. Advanced sensors accurately detect the user’s movements and inform the microprocessor where state-of-the-art 
artificial intelligence enables the knee to respond to the user’s needs. 
 A powerful motor provides consistent stance phase but also free swing phase. Delivering active extension when standing up, controlled 
resistance when descending, active flexion and extension during walking and energy returning stance flexion, Power Knee facilitates 
symmetrical weight distribution and natural gait.
