Kenevo

Walking with a prosthesis for the first time means building up confidence step by step. This also applies if you use other devices or generally do not move about much. You become more flexible and independent only when your confidence in the prosthesis grows.

The Kenevo puts a focus on safety. It provides support in typical everyday situations with its basic functions. Moreover, the activity modes make it highly adaptable. The Kenevo keeps pace with your growing skills, for instance during rehabilitation, and adapts itself to decreasing mobility equally well.

The new Kenevo features new functions that make day-to-day life easier and richer. They include the intuitive assisted descent of ramps and the use of an indoor bicycle (bicycle ergometer). The prosthesis is easier to don and it can be charged without removing the foam cover. The knee joint can be configured using a smartphone with the Cockpit app.

Bluetooth®

Integrated Bluetooth® permits straightforward communication with the knee joint. An existing connection is displayed with an LED.

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.

Inertial motion unit (IMU) and electronics

A gyroscope and acceleration sensors allow the spatial position and acceleration of the Kenevo to be determined in real time. A microprocessor receives the signals and controls the motion of the joint in real time. This is key for ensuring a high level of safety and adapting to the skills of the user.

Hydraulic unit

The hydraulic unit is controlled by the microprocessor. It generates movement resistances, allowing adaptation to the individual needs of the user.

Carbon fibre frame

In order to withstand the varied demands of everyday life, the frame is made from carbon – an especially strong, high-grade and lightweight material.

Inductive charging unit

The inductive battery charger is magnetically attached to the back of the knee joint, making easy charging possible.

AXON tube adapter

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. This technology is valuable even for initial walking after a leg amputation.

Benefits at a glance

Kenevo – safe and supportive

Supported sitting down
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
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.

Standing function
Standing function

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.

Enhanced safety
Enhanced safety

The swing phase refers to the part of walking where the prosthesis swings through while the other leg rolls over from heel to toe on the ground. With its reliable stance release, the Kenevo provides you with sufficient ground clearance when taking small steps and walking slowly, even when using walking aids. Thanks to stumble recovery Plus, the prosthesis recognises when you stumble and are at risk of falling or when you stop a movement. The knee joint then switches immediately to a high level of flexion resistance – all of which enhances safety.

Intuitive indoor bicycle function
Indoor bicycle function and Cockpit app

You can configure several settings of the joint using a smartphone with the Cockpit app. For example, you can activate the intuitive indoor bicycle function. The indoor bicycle function makes training on an indoor bicycle intuitive. 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. This improves stability and can support your mobility, both indoors and out. 

Wheelchair function
Wheelchair function

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.

Charging with foam cover
Additional benefits in everyday life

The Kenevo can now be charged conveniently without removing the foam cover. In addition, a new donning function makes the prosthesis easier to put on thanks to complete flexion of the knee joint. This makes day-to-day life easier and leaves more time for important things.

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.”

Christian, O&P Professional

"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."

Functionality

Adaptable thanks to various modes

Explanation of the three activity modes

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 O&P professional adjusts the appropriate activity mode 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, which is a stable prosthesis, therefore provides a high level safety and does not allow unexpected movements.

The locked mode is thus especially appropriate if you have little control over your residual limb, primarily walk only short distances indoors and spend most of your time sitting.

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.
