Össur’s POWER KNEE is an actively powered microprocessor prosthetic knee for people with a transfemoral amputation or limb difference. The motor-powered “smart” prosthesis uses advanced algorithms to detect human movement patterns, thereby learning and adjusting to the wearer’s speed and cadence in real-time. The POWER KNEE creates motion by providing active powered assistance while distinguishing whether the wearer is walking on varying surfaces, inclines, or declines, or sitting and standing. When ascending stairs, the wearer is able to perform a more natural step-over-step pattern, and experience more controlled resistance when descending stairs or ramps. The prosthesis’ motor-powered energy helps encourage more symmetrical motion and enhance the wearer’s endurance by helping them conserve their own energy.
