Sport knee joint
A sports knee joint has to withstand the high loads that develop and act on the prosthesis while running. The familiar, patented principle of rotation hydraulics is used in a modified form in the 3S80 Sport as well. The joint is also equipped with a manual lock. Compact and robust, the 3S80 Sport is optimised for any type of running.
The lower leg of the prosthesis swings through freely to an angle of about 60° in the flexion direction. Even at high stride rates, a smooth extension stop is ensured by extension damping applied along the entire extension movement, which increases significantly shortly before reaching the end position. Flexion and extension damping can be adjusted separately and individually.
*Specific adaptations are available on request.

Knee joint, monocentric, with rotation hydraulics
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.
