3R80 - Knee prosthetics

Knee joint, monocentric, with rotation hydraulics

Show your determination, and don’t let anything stop you.

As a prosthesis wearer, you want to be confident that your knee joint meets your daily requirements and supports changing walking speeds. Through continuous further development, our goal is to offer you a knee joint that makes you as independent as possible in everyday life.
The 3R80 with its unique rotation hydraulics principle is now also approved for prosthesis wearers with a body weight of up to 150 kg. With the 3R80, both the stance and the swing phase are controlled by the hydraulics. For example, walking down stairs step-over-step and walking down inclines are effectively supported by closely approximating a physiological gait pattern, even at various walking speeds. The 3R80 is water-resistant to a depth of 3 metres and has a manual lock for even better safety, especially in wet areas.

Thanks to easy initiation of the swing phase, the 3R60 knee joint allows you to walk at various speeds – whether you are going for a hike or strolling through a market. You benefit from a larger ground clearance during swing-through of the joint, reducing your risk of stumbling. The special joint design also gives you more stability in the stance phase and prevents unwanted flexion of the joint. The 3R60 also makes it possible for you to walk down gentle slopes.
