C-Leg 4 Microprocessor Knee.
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.
It’s the world’s most studied prosthetic device. Full stop.
Up to 90%
of C-Leg users prefer it to their previous mechanical prosthesis*
25 years
of continuous microprocessor knee development and user input have led to the new C-Leg 4.
100,000
fittings have helped more users regain their mobility than any other microprocessor knee.
