Benefits at a glance
Supported sitting down
The Kenevo automatically detects when you sit down and assists you. Even if your movement is slow, you stay in control, because the joint bends accordingly slowly. This feature makes the Kenevo a very stable leg prosthesis. You can hold on to the chair or a walking aid with your hands while sitting down.
Supported standing up
It is possible to put weight on the Kenevo while standing up. Even if you need to pause again, this is not a problem – the leg prosthesis reacts immediately and allows you to pause with the knee flexed. This is a function for balance and stability.
The Kenevo provides the greatest possible safety while standing, regardless of the selected activity mode. In activity modes A and B, safety is provided by the locked stance phase. The stance phase refers to the moments where you stand on the floor with the prosthesis. In the more dynamic activity mode C, stable standing is possible even with the knee flexed, thanks to the intuitive stance feature.
Carpet edges, thresholds or other tripping hazards should not be an obstacle. The Kenevo has various safety features which are proven to reduce falls. These include Stumble Recovery Plus, this feature covers the entire swing phase, providing the highest level of safety possible. The difference between a stumble and fall can take milliseconds. Unlike other MPKs, the Kenevo does not need to detect a stumble in order to provide the additional support. Instead, As a result, the knee is already prepared on every swing phase for a stumble, therefore there is no reaction time and the risk to the patient is reduced even further. If a stumble was to occur as the knee is extending, the stance resistance is already very high preventing the knee from bending further when the patient lands on it following a stumble.
Intuitive indoor bicycle function and Cockpit app
With the intuitive indoor bicycle function, you can train intuitively on an indoor bicycle. As soon as you sit down and make pedaling movements, the Kenevo automatically switches to non-damped mode after a few revolutions. The joint switches back to "normal" activity mode automatically when you get off the indoor bicycle.
Assisted descent of ramps
A new function of the Kenevo provides intuitive support while walking down ramps. As you bend the knee the resistance increases to support and control your descent. This improves stability and can support your mobility, both indoors and out.
Thanks to additional ground clearance, the Kenevo also facilitates sitting in a wheelchair. With only one hand movement, the prosthetic knee joint can be locked between a slightly bent position and an almost fully extended leg. This prevents the leg prosthesis from getting caught on the ground.
Additional benefits in everyday life
The Kenevo can now be charged conveniently without removing the foam cover due to the new charger design. In addition, the donning function allows you to put on the prosthesis while seated. In Mode A, B and B+ the Kenevo is locked in the stance phase. To allow the Kenevo to bend easily, we have added the donning function. When the charger is disconnected, it is possible to flex the knee once with minimal resistance. In Mode C it is already possible to bend the knee against the resistance which is always present in the knee. This makes day-to-day life easier and leaves more time for important things.
Bob and his Kenevo
Bob's greatest passion is his cars. Organising his day flexibly and independently is important to him. To help with this, the Kenevo provides Bob reliable safety with each step.
Detlef and his Kenevo
Detlef is most comfortable at home, but he loves his walks and never misses one. He loves watching his grandson play football. He felt very uncertain after his amputation due to his age, but the Kenevo showed him that he can put his confidence in a knee joint. It is reliable and gives him safety in his everyday life, with every step he takes.
Michael and his Kenevo
Michael made the most of his rehabilitation with the Kenevo – placing his confidence in the knee joint was the biggest challenge at first. Together with his physiotherapist, Michael learned to navigate stairs and uneven surfaces step by step. Today, Michael wears a Genium X3. He works as a logistics specialist in a production facility and enjoys doing sports with his wife and friends.
Markus, rehabilitation physiotherapist
“The Kenevo is ideal for rehabilitation because I can let this knee joint grow with the patient. Thanks to its three activity modes, it supports the patient and their needs on a completely individual basis.”
"Safety is the most important thing for the patient directly after the amputation. The patient has to be confident that they can rely on the prosthesis."
David and his Kenevo
David has an NHS Kenevo funded via the Microprocessor Knee policy. He is now able to visit his daughter's house which has a steep driveway and can negotiate varied terrain. He feels much more secure on this limb than previous ones and hasn’t had any falls which he used to have frequently.
The Kenevo has three activity modes. This gives it an extraordinary ability to adapt to your individual needs and developing skills, for example, during rehabilitation. Your Prosthetist adjusts the activity mode suitable for you on the knee joint.
Mode A: locked mode
In mode A, the Ottobock knee joint is locked and does not initiate a swing phase. The Kenevo, as a stable prosthesis, provides high safety and does not allow unexpected movements.
The locked mode is especially appropriate if you have little control of your residual limb, mostly walk only short distances indoors and sit most of the time.
Mode B: semi-locked mode without stance phase flexion
In this mode B, the joint is locked during the entire stance phase. It is released for the swing phase when you start the pendulum movement of your leg. This is largely independent of your gait pattern and whether you are using other walking aids. The Kenevo always initiates the swing phase at the right time.
This activity mode is especially appropriate if you have average control over your residual limb, travel short distances and walk slowly.
Mode B+: semi-locked mode with stance phase flexion
This activity mode corresponds to mode B, but is supplemented by stance phase flexion at heel strike of up to 10°. That may sound technical, but for you it mainly means that you can walk on moderate slopes. As soon as your heel hits the ground, the knee joint bends slightly. This results in a movement that looks more natural.
This activity mode is suitable if you have already built enough confidence in your prosthesis in order to walk with stance phase flexion.
Mode C: yielding mode
You achieve an even more natural gait along with a high level of safety in yielding mode. In contrast to the other activity modes, the stance phase is not locked in mode C, but exhibits a high level of damping. This supports you when walking on uneven ground, ramps and stairs with the transfemoral prosthesis. The swing phase can be initiated earlier, which facilitates the more dynamic movements.
Activity mode C is suitable for you if you have moderate control over your residual limb, are able to deal with various everyday situations and can cover short to medium walking distances outdoors.
The Kenevo is suitable for moderately active users and as a knee joint for rehabilitation after an amputation. It is approved for users with an above-knee amputation, knee disarticulation or hip disarticulation.
We recommend charging the battery overnight on a daily basis.
The intuitive indoor bicycle function of the new Kenevo makes training on a stationary indoor bicycle (bicycle ergometer) an option now. This has been tested and approved. Riding a bicycle with the Kenevo has not been tested and is therefore not permitted.
The intuitive indoor bicycle function is only available in mode C and has to be activated in advance in the K-Soft software by your Prosthetist. It can then be switched on intuitively by making a pedalling movement or via the Cockpit app.
The Cockpit app is an app for Kenevo users. The Cockpit app can be used to make small adjustments to the knee joint. The Cockpit app can be downloaded in the Google Play Store (for Android devices) and the App Store (for iOS devices).
Besides the existing features, the new Kenevo offers an intuitive indoor bicycle function, an easy put on function and intuitive assistance while walking down ramps. Plus, the Kenevo can now be linked with the Cockpit app. Charging with a foam cover is easy now thanks to a new accessory.
