The Pancake Active Power Knee (Power Knee) is the world's first motor-driven microprocessor knee.
Active Assist powers flexion and extension to simulate centripetal and centrifugal muscle activity.
Advanced sensors accurately detect the user's movements and then notify the microprocessor, which utilizes state-of-the-art algorithms to make the knee responsive to the user's needs.
Powerful motors provide consistent standing phase and free swing phase. Providing active extension when standing and controlled damping when walking downhill.
providing active flexion and extension while walking, and energy-returned standing flexion.
The Pancake Active Power Knee (Power Knee) therefore promotes symmetrical weight distribution and a natural gait.

Key Features:
Automatically adapts to real-time stance and swing control
Energy-returning stance flexion
Provides active assistance when walking on level ground, striding up stairs and standing up
Provides intuitive knee lock during standing to promote even weight distribution
Typical use time of up to 25 hours on a single battery
Replaceable battery can be recharged when fitted to the knee, or separately
Comes with the Össur Logic app for iOS devices, which provides simple practitioner setup and adjustments
