C-Leg 4
Benefits at a glance01
Greater Mobility
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.
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, they can enjoy a relaxed, comfortable position with a free-swinging joint thanks to the supported sitting function.
Easier user experience
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.
Helpful Training Function
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.
Weatherproof Design (IP67)
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.
MyMode Plus
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.

Customisable Shield Insert
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.
New Colour Option
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.
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 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.
Stance Function Selection
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.
More Support For Prosthetists
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.
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.
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.
Reliability
Twenty-five years of continuous development based on real practitioner and user experiences have made C-Leg the most preferred and trusted microprocessor-controlled knee joint in the world. It’s also the most widely studied and proven. 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.
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.
