Ossur PowerKnee - Model MPK - Motor-powered Microprocessor Knee
The Power Knee is a motor-powered microprocessor knee (MPK). It provides active assistance while walking on level-ground, climbing and descending ramps or stairs and when standing up. Power Knee enables amputees to maintain and regain mobility and participate in the daily activities they enjoy.
Power Knee is Made to Move You
Power is fundamental to the biomechanical systems that move us.
If you’re living with limb loss or limb difference, that power is a missing ingredient. Restoring it can be transformational.
A New Era in Motion
The Power Knee is unlike anything you or your patients have experienced. A new category of Actively Powered prostheses, you can expect more, from the initial fitting to the six-month outcome. And you can expect to invest less time in adjustments and more time for helping your patients live their lives fully.
Confidence
The stability and powerful motion of the Power Knee supports you to navigate your world.
Endurance
Power Knee adds its energy to your own helping you to preserve your energy.
Preservation
Adding Power gives you the opportunity for better symmetry and more natural motion – this means less strain on the rest of your body – now and into the future.
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
- Auto-adaptive real-time stance and swing control
- Energy returning stance flexion
- Active assistance in level-ground walking, step-over-step stair ascent and when standing up
- Intuitive knee lock when standing, facilitating equal weight distribution
- 25-hour typical usage on a single battery
- Replaceable battery, can be charged in knee or separately
- Accompanying Össur Logic app for iOS devices provides simple practitioner setup and adjustment
