Many updates to our signature C-Leg Microprocessor Knee are based on feedback we received directly from C-Leg wearers. That’s why the C-Leg 4 is available in the original lighter Desert Pearl colour as well as a new darker shade, Midnight Shadow, which is a deep gun metal grey colour.

You can personalise the look of your prosthesis thanks to a new customisable shield insert. Not only does this robust, durable cover protect the C-Leg 4 from wear and tear, it also empowers you to show off your unique style with each step. So be unique and unleash your inner creativity!

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.

As you walk down the stairs or down a slope, you will use the stance flexion resistance to allow you to descend safely. With the new C-Leg 4, we’ve given you the option to select how you want the stance flexion behaviour to be delivered. With the supported function enabled, the knee joint resistance will dynamically increase as the knee joint angle increases - giving you confidence and self assurance that you are safe on the ramp or on the stairs. This feature is selectable within C-Soft Plus and works independently to the 'Supported Sitting' function.  

In the new C-Leg 4, we have improved the stance release feature so that if you need to move in small, confined spaces and take smaller and quicker steps, you can achieve stance release easily and safely.

The C-Leg's Stumble Recovery feature has now been upgraded to our well known 'Stumble Recovery Plus'. Unlike other MPK's, our Stumble Recovery Plus feature is always active throughout the entire swing phase. During both swing and flexion and swing extension, the Stumble Recovery Plus feature is ready and armed to support you should a stumble occur.

Independently selectable within C-Soft Plus, the 'Supported Sitting' Function can change the behavior of the C-Leg when you sit down. This new feature will provide you with even more support by dynamically increasing the resistance as the knee joint angle increases.

For people who happen to exit the Intuitive Stance Function too easily, we've added a smart new feature that can be selected to support you. The Deliberate Stance function 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.

Want more support for your favorite activities? MyMode Plus offers extensive options for work, leisure, and athletics. Select two settings for your prosthetist to program for easy activation in the Cockpit app or via movement pattern.

Ideal for those first steps and for sessions with your physiotherapist, the new Training Function lets you and your therapist hear a beep when stance release has been performed correctly.

We listened to your feedback that some C-Leg wearers found it difficult to insert the charging plug using only one hand. We've changed the design of the plug hole by adding a sliding flap and we've added an audible and tactile "click" so they can feel when the plug is inserted correctly.
