Modular Sports Knee Joint w/ thinner oil
The patented principle of rotation hydraulics already familiar from the 3R80 prosthetic knee joint is also used in a modified form in the 3S80 Sport. The 3S80 offers optimal swing phase control for running along with extension damping throughout the entire extension movement, which ensures harmonious extension even at high stride rates. The larger flexion angle for jogging and sprinting is precisely controlled by flexion damping. Flexion and extension damping are individually and independently adjustable. The 3S80 also features a manual lock.

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.
