Kenevo - for low mobility
Reclaim your sense of security
For a new safety standard
Walking for the first time on a prosthesis means building trust step by step. This also applies if you are using other aids such as a walking stick or less active. Only when confidence is growing in the prosthesis system, you become more flexible and independent, for example, from the help of relatives.
Therefore, the Kenevo focuses clearly on safety. The knee joint is the world's first fitting solution of the latest technology specifically for the needs of less active people - as a leg prosthesis the Kenevo sets a new global standard. With its special basic functions it provides support in typical everyday situations. Moreover, the activity modes provide high adaptability. The Kenevo grows with your skills, for example during rehabilitation, and adapts itself equally well for a decreasing amount of mobility.
Carbon fibre frame
In order to withstand the varied demands of everyday life, the frame is made of carbon - an especially strong, high-grade and lightweight material.
AXON tube adapters
Sensors in the tube adapter measure the ankle moment and the vertical force acting on the joint. The sensor data help make a natural movement pattern possible. For the first time walking after a leg amputation, this is a valuable technology.
Rechargeable battery and knee angle sensor
A rechargeable battery provides the energy required to control the joint. The knee angle sensor provides important information to precisely determine the forces acting on the prosthesis.
Inductive charging unit
The inductive battery charger is magnetically attached to the back of the knee joint - easy charging through the thin clothing fabric is therefore possible.
Integrated Bluetooth technology permits simple communication with the knee joint. An existing connection is indicated by an LED.
Inertial Motion Unit and Electronics
Gyroscope and acceleration sensors let you determine position and speed in space. A microprocessor receives the signals and controls the motion of the joint in real time. An important prerequisite for high safety and to adapt to the skills of the prosthesis user.
The hydraulic unit is controlled by the microprocessor. It generates movement resistance, allowing adaptation to the individual needs of the prosthesis user.

Benefits at a glance
Supported sitting down
The Kenevo automatically detects when you sit down and supports 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. With your hands, you can hold on to the chair or a walking aid while sitting down.
Supported standing up
While standing up, it is possible to put weight on the Kenevo. Even if you need to pause again, this is not a problem - the leg prosthesis reacts immediately and allows a pause with the knee flexed. This is a function for balance and stability.
Carpet edges, thresholds or other tripping hazards should not be an obstacle. Using the stumble recovery Plus, the Kenevo recognizes if you stumble and run the risk of falling or stop a movement. The knee joint then switches immediately into a high flexion resistance.
Thanks to additional ground clearance the Kenevo also facilitates sitting in a wheelchair. With only one hand movement, the knee joint can be locked between a slightly bent position and an almost stretched leg. This prevents the leg prosthesis from getting caught on the ground.
Independently of the selected activity mode, the Kenevo provides the highest possible safety for standing. In activity mode A and B, safety is guaranteed 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 thanks to the intuitive stance function even with the knee flexed.
Unique swing phase initiation
The swing phase refers to the part of walking, where the prosthesis swings through during the heel-toe gait of the other leg on the ground. In activity modes B and C, the swing phase triggers reliably even for small steps and at varying load, e.g. by walking aids. Even when walking very slowly, there will remain enough clearance to ground while swinging through. All this ensures high safety.
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 orthopaedic technician 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. Thus, the Kenevo, as a stable prosthesis, provides maximum safety and does not allow unexpected movements.
Therefore, the locked mode is suitable if you have little control over your residual limb, usually only go short distances indoors and mostly sit.
Mode B: Semi Locked Mode without stance phase flexion
In this mode B, the joint is locked during the entire stance phase. It unlocks when you start the swing movement of your leg for the swing phase. This is largely independent of your gait pattern and whether you are using other walking aids. The Kenevo initiates the swing phase always at the right time.
This activity mode is especially useful if you have a medium control of your residual limb, cover short distances and walk slowly.
Mode B+: Semi Locked Mode with stance phase flexion
This activity mode corresponds to the mode B, but is supplemented by a stance phase flexion at heel strike of up to 10°. What sounds technical, means that you can walk on moderate slopes. As soon as your heel hits the ground, the knee 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
A more natural walking with the same high level of safety can be reached in the Yielding Mode. In comparison to the other activity modes, the stance phase in mode C is not locked, but has a high attenuation. This helps you go with the transfemoral prosthesis on level ground, on slopes and stairs. The swing phase can be initiated earlier, which facilitates the more dynamic movements.
Activity mode C is suitable for you if you can control your residual limb moderately, are able to deal with various everyday situations and cover short to medium walking distances outdoors.
