C-Leg: Trusted for good reason.
Since 1997, one particular microprocessor knee has set the standard for every other available option. Now, with the new C-Leg 4, our signature knee is raising the bar even higher.
It’s the one patented technology that empowers you with the proven performance you need to live the healthy, active life you want. C-Leg adapts to your unique gait pattern and walking speeds, so you can keep your focus where it matters — not on your next step, but on where you want it to take you.

New Colour Option
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.
NHS Microprocessor Knee Funding for C-Leg 4.
Ottobock has been proudly providing the C-Leg 4 to medium to highly active individuals through NHS England funding since 2016. The funding means that amputees have access to an MPK which provides the most natural walking pattern helping users improve their mobility and gain independence.
