C-Leg


With over 100,000 fittings to date, the C-Leg is trusted by more users than any other microprocessor knee in the world. And it’s no wonder: Studies show the C-Leg provides the exceptional reliability and performance users need to focus on what really matters — enjoying a healthy, active lifestyle.

With over 100,000 fittings to date, the C-Leg is trusted by more users than any other microprocessor knee in the world. And it’s no wonder: Studies show the C-Leg provides the exceptional reliability and performance users need to focus on what really matters — enjoying a healthy, active lifestyle.

From descending stairs and ramps, to navigating uneven terrain, to walking backward, the C-Leg dynamically adapts to a wide variety of everyday situations.

Smart control via app

With the Cockpit app, users can fine tune MyMode Plus and other settings individually, switch between MyMode Plus options, check their knee’s battery status, set their volume, track their activities, perform a knee joint self-test if needed, and much more — all via their iOS or Android smartphone.

Stance function

Users can choose between intuitive and deliberate stance with the help of their O&P professional. Intuitive stance uses sensor data to detect whether the user needs support while standing or taking a step, while deliberate stance requires more conscious movements to resume flexion.

Enhanced safety
Stumble recovery Plus

Stumble recovery Plus is active at all times with the C-Leg 4. This ultra-precise feature automatically detects fall-like movements during the swing phase of users’ gait and activates the resistance they need to avoid a fall, recover their balance, and maintain greater stability.

Support and comfort for sitting

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, the user can enjoy a relaxed, comfortable position with a free-swinging joint thanks to the automatic sitting function.

Water-resistant design (IP68)

With the C-Leg 4, users don't have to worry if the knee joint occasionally comes into contact with fresh water. 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 afterwards.

The new colour of the C-Leg 4 – Midnight Shadow.
Two color options

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 available in two colors: the original lighter Desert Pearl as well as a darker shade, Midnight Shadow.

C-Leg 4
Easier handling

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. The charger enables one-handed use. Plus, there’s a USB charging adapter available.

Training feature
Helpful training function

A 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.

Manual locking function

With the manual locking function users can conveniently secure the C-Leg 4 in extension with a simple tapping pattern, even when using a cosmetic fitting. This is particularly helpful during sporting activities, for example.

More freedom of movement

The key to fluid movement is a knee that responds quickly to different inclines and surfaces. With the C-Leg 4, users get improved stance release and increased support for descending ramps and stairs, enabling noticeably smoother and more reliable movement.

Принцип действия

Elegance

Thanks to innovative new developments, C-Leg 4 users enjoy more harmonious, fluid movement patterns — even when taking small steps, changing walking speeds, or navigating different types of terrain such as sand, grass, and gravel. Even users who have never worn a C-Leg are able to adjust to the prosthesis over a relatively short period of time.

Intelligent system

Ottobock is continually developing the C-Leg to ensure users get the latest and greatest in microprocessor knee technology. The C-Leg supports users throughout the entire gait cycle, adjusting to their unique walking patterns in real time. So, whether they’re going downstairs step-over-step, descending slopes, or navigating uneven terrain, C-Leg users can truly trust their prosthesis as they move through their daily activities.

Safety

Many studies have proven that users fall significantly less frequently with the C-Leg than with conventional prostheses, making the C-Leg one of the most reliable leg prostheses in the world. In addition, the new C-Leg 4 provides even greater safety and stability via stumble recovery Plus and increased support for sitting down.

Reliability

Twenty-five years of continuous development, based on the experiences of qualified personnel and users, have made the C-Leg the most preferred and trusted microprocessor knee worldwide. It is also the most widely studied and proven microprocessor knee. In fact, 77 scientific publications featuring upwards of 2,500 subjects clearly support the benefits that C-Leg users across the globe enjoy every day.
