Discover the new C-Leg 4 Microprocessor Knee.

The new C-Leg 4 is now IP68, enabling you to have greater confidence in diverse environments. Whether you're walking the dog, caught in a rain shower, or accidentally splashed when watering the garden, you can be assured that the electronics in your C-Leg are protected from dust, sand, dirt and occasional submersion in freshwater (up to 3m for 1hr).

*Please note, C-Leg is not corrosion resistant and the mechanical components may corrode.

C-Leg 4's new manual locking function enables even more stability by conveniently locking the MPK in a fully extended position. Activated by a simple tapping pattern, this feature is especially useful during sporting activities or in situations where increased safety is needed.

When walking down slopes or stairs, C-Leg's stance flexion resistance allows you to descend safely. With the C-Leg 4, you can choose how the stance flexion behavior is delivered. When the supported function is enabled, the MPK's resistance dynamically increases as the knee joint angle increases, providing you with confidence and self-assurance on ramps or stairs.

*This feature is selectable within C-Soft Plus and works independently to the 'Supported Sitting' function.  

The C-Leg 4 features an improved stance release function, allowing you to move easily and safely in small, confined spaces with smaller and quicker steps.

The new C-Leg 4 includes 'Stumble Recovery Plus,' which sets it apart from other MPKs. This feature is always active throughout the entire swing phase. Whether in swing flexion or swing extension, Stumble Recovery Plus is continuously ready to support you should a stumble occur.

The C-Leg's 'Supported Sitting' function offers enhanced support when sitting down by dynamically increasing resistance as the knee joint angle increases.

*This feature can be independently selected within C-Soft Plus.

For users who exit the Intuitive Stance Function too easily, we've added a smart new feature to the C-Leg 4 that can be selected to support you. Deliberate Stance provides a more robust standing lock which is harder to exit and therefore is more appropriate for C-Leg wearers that require enhanced standing support.

Looking for more support for your favorite activities? MyMode Plus offers extensive options for work, leisure, and sports. You can choose two settings for your prosthetist to program, which can then be easily activated using the Cockpit app or a movement pattern.

Now it’s even easier to get the most out of your C-Leg. With deep sleep mode, you can save battery when sitting for long periods or when the prosthesis is not in use, such as on long flights.

The C-Leg 4's Training Function is perfect for those initial steps and sessions with your physiotherapist. When activated, both you and your therapist will hear a beep when stance release has been performed correctly.

The redesigned charging port on the new C-Leg 4 makes it easier to insert the charging plug using one hand. Featuring a sliding flap and both an audible click and tactile feedback, you are now able to feel when the plug is inserted correctly.

Many updates to our signature C-Leg Microprocessor Knee are inspired by feedback from users. As a result, the C-Leg 4 is available in the original lighter Desert Pearl color and a new darker shade, Midnight Shadow, which is a deep gunmetal grey colour.

You can customise the appearance of your C-Leg with our customisable shield insert. This durable cover not only protects the C-Leg 4 from wear and tear but also empowers you to show off your unique style with every step. So be unique and unleash your inner creativity!
