C-Leg®

C-Leg®

The C-Leg® microprocessor-controlled prosthetic knee started a revolution for above‑knee amputees. Since it was introduced in the U.S. in 1999, more than 40,000 people worldwide have taken advantage of the unparalleled stability offered by the C-Leg®. The most clinically evaluated microprocessor knee in history, C-Leg® is backed by evidence demonstrating increased efficacy in safety, energy efficiency and cost effectiveness when compared to other prosthetic knees – making this technology the Standard of Care. C-Leg®’s superb stumble recovery and smooth swing activation provides a confident, natural gait. Users can speed up, slow down, take on hills and go down stairs step‑over‑step—all with a secure, comfortable stride.

Benefits

The latest generation of C-Leg® adds:



  • Improved swing phase control. Users experience easier initiation at swing, with a smoother, more natural movement.
  • Higher weight limit: 300 lbs.1 Benefiting even more users, including those who weigh more or who routinely carry or lift heavy loads. Genium™ and C-Leg® are rated for the highest weight limits in the category.
  • Improved stumble recovery. Increased resistance in case of a trip or stumble.
  • A third mode. Another choice, personalized for the user.
  • Adjustable safety mode. The default setting can be adjusted, personalized to the user’s preference.
  • Improved protection. New silicone caps covering the charging and adjustment jacks are now attached to the knee, securing the caps and improving protection from foreign matter and moisture.


Introduced to the world in 1997, the C-Leg® was the first prosthesis system to intelligently control and adapt to an individual’s gait. To do this, the C-Leg® (and the Compact model) takes advantage of microprocessor-controlled hydraulics, which adapt dynamically to all walking speeds in real time. The revolutionary microprocessor that controls the C-Leg® receives feedback from multiple sensors 50 times a second, making adjustments in real time. In addition, the microprocessor can reliably secure the stance phase in both the C-Leg® and Compact knees. The result is a system that recognizes which phase of gait the user is in—and reacts accordingly. This keeps your knee stable when you weight it, free-swinging when you step through—and always ready to support you if you stumble. C-Leg technology offers the advantages of permanent stance phase control, the ability to weight the prosthesis during flexion, dynamic alignment, less energy expenditure while walking, and relief for the sound side and the rest of the body.

Features

  • Transformative technology: The revolutionary microprocessor that controls the C-Leg® receives feedback from multiple sensors, allowing the knee to make adjustments in real time.
  • Always thinking about your security—so you don’t have to
  • The C-Leg® offers tremendous stability—and flexibility. You can speed up, slow down, and go down stairs step-over-step with the assurance that the C-Leg® is there for you.
  • Stumble recovery: Whenever the C-Leg® senses that you’re in an insecure position—such as when you trip or stumble—it will increase resistance to provide the support you need to recover.
  • Multiple modes for multiple uses: The C-Leg® offers two activity modes, set by your prosthetist for walking and other favorite activities, such as job tasks, golf, or riding a bike.
  • Stand at ease: A Standing Mode lets you lock the leg yourself using a specific motion pattern. With the leg flexed between 7º and 70º you use less energy, whether you’re washing dishes or standing in line.
  • Switch over: Switching between modes is as easy as bouncing on your toe—or a press of the wireless remote control.
