Proven performance at every step
The key to fluid movement is a knee that responds quickly to different inclines and surfaces. With the new C-Leg 4, users get improved stance release and increased support for descending ramps and stairs, enabling noticeably smoother and more reliable movement.
The C-Leg 4 detects when users sit down, mirroring their speed to keep them stable and in control — even if they’re using a chair or a walking aid for support. Once seated, they can enjoy a relaxed, comfortable position with a free-swinging joint thanks to the supported sitting function.
Now it’s easier than ever for users to get the most out of their C-Leg. Deep sleep mode saves battery during long flights, camping, or other activities where power supply is limited. A redesigned charger enables one-handed use. Plus, there’s a USB charging adapter available.
A new training function provides a feedback signal after every successful swing phase initiation to support troubleshooting and gait training as users get accustomed to their prosthesis. This feature can be activated and deactivated by the prosthetist or user via the Cockpit app.
With the C-Leg 4, users don't have to worry about occasional water splashes. Whether they’re walking past a sprinkler, working in the garden, or caught in a sudden rain shower, the C-Leg is designed to stay protected as long as the joint and components are dried off afterward. The C-Leg is NOT WATERPROOF.
Now, users can easily get more support for their favourite activities. MyMode Plus offers a fantastic selection of options for work, leisure, and athletics. Together with their prosthetist, users can select two settings for easy activation in the Cockpit app or via a movement pattern.
Users can personalise the look of their prosthesis thanks to a new customisable shield insert. Not only do these robust, durable covers protect the C-Leg 4 from environmental factors or wear and tear, they also now empower users to show off their unique style with each step.
Many of the updates to our signature C-Leg microprocessor knee are based on feedback we received from users and professionals. In fact, that’s why the C-Leg 4 is now available in two colors: the original lighter Desert Pearl as well as a new darker shade, Midnight Shadow.
With the Cockpit app, users can fine tune MyMode Plus and other settings individually, switch between MyMode Plus options, check their knee’s battery life, set their volume, track their activities, perform a knee joint self-test if needed, and much more — all via their iOS or Android smartphone.
With their prosthetist’s help, users can choose between intuitive and deliberate stance functions. Intuitive stance uses subtle cues to detect whether users need support for standing or taking a step, while deliberate stance requires more conscious movements to resume flexion.
Featuring C-Soft Plus 1.10 software, the new C-Leg 4 offers even more preset options and video tutorials to assist professionals and users throughout the fitting process.

Answers for you
Numerous studies have investigated the advantages of C-Leg technology for people with a transfemoral (above-knee) amputation. These studies have shown that the frequency of falls is much lower with the C-Leg compared to conventional prostheses, proving a high level of safety.
In addition, studies show that C-Leg users don’t have to concentrate on their prosthesis at all times, but rather can move more freely in everyday situations. C-Leg users have more confidence in their prosthesis, and are also able to boost their activity levels, vary their walking speed and expend less energy while walking.
You can get the C-Leg from your NHS Limb Centre via the Microprocessor Knee Policy if you qualify against the specific criteria, or through a Private Prosthetic Provider, who will adapt the prosthesis to your individual needs.
Many practitioners offer trial fittings which take place over a predetermined period of time and are monitored by Ottobock when needed. Just talk to your prosthetist for more details.
What’s included in a prosthetic fitting?
A prosthetic fitting includes all components from the foot to the knee joint system, including the socket, which will be customised to your individual needs by your prosthetist. The assembly and setup of the system are also included, as well as regular service inspections during the entire period you use the C-Leg.
A vibration signal notifies the user well in advance when the battery starts getting low. When it’s drained, the C-Leg automatically switches to a predefined safety mode so that the user’s preferred resistance in the stance phase is activated.
Although the C-Leg is weatherproof and well suited for contact with water in various everyday situations, such as rain showers or light splashes. It is not fully waterproof. You should not wear it in the shower or for activities like swimming.
Many users are able to walk downstairs step-over-step on their first day with the C-Leg prosthesis. However, it can also take several days or even weeks for users to completely acclimatise to using the C-Leg in everyday situations depending on their unique condition and circumstances.

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 (static bike). The prosthesis is easier to put on and it can be charged without removing the foam cover. The knee joint can be configured using a smartphone with the Cockpit app.

Genium
With the market launch of the Genium leg prosthesis, Ottobock opened up entirely new horizons for prosthesis wearers: a nearly natural gait pattern, climbing stairs step-over-step, walking backwards, relaxed standing – to name just a few examples. The benefits of being fitted with a Genium have been scientifically proven in multiple studies.
The Genium has been enhanced based on human movement as the model. The result is a noticeably smoother gait and even better support and safety in everyday situations, for instance on ramps, in confined spaces or when changing walking speeds. Five individually selectable MyModes support special movement patterns at work or play.
The Genium can be configured with the Cockpit app, which is now available not only for Android but Apple (iOS) devices as well.
