It assists me at the right moments, it gives me a little push into the next step or up stairs. It's made my life easier and more comfortable.

The Power Knee uses cutting edge bionic technology developed by Össur to respond instantly to the precise movements the amputee makes and react to motions of sitting, standing, climbing stairs and walking and also prevent stumbles.
Successfully trialled in the US and Iceland, the Power Knee represents a new category of prosthetic technology. Unlike conventional prostheses, which require an amputee to consciously move them, by directly engaging the anatomical structures of their remaining limb, the Power Knee is designed to replace lost muscle function and perform as an integrated extension of its user.
It uses battery power to replace the lost muscle capability and asymmetrical movement often found in people with limb loss.
With integrated artificial intelligence (AI) systems, sophisticated motion sensors and wireless communications capabilities, Power Knee is a “smart” prosthetic limb, which can “learn” its user’s walking style and automatically make real-time adjustments based on changes in speed, stride, or terrain.
Power Knee user David Jonsson commented, “a motorised knee is different from a passive knee, which just follows the motion of the body. The motor gives you more control over the knee, it allows you to mimic the natural gait more easily and allows the user to use their body more like the way is intended to work, because they do not have to compensate for using a prosthesis and muscle loss.”
