3S80 Sport knee joint
A sport knee joint must withstand the high loads that arise and act on the prosthesis when running. The patented principle of rotation hydraulics already familiar from the 3R80 prosthetic knee joint has been modified for use in the 3S80 Sport model. In addition, the joint has a manual lock. Compact and robust, the 3S80 Sport is optimised for all kinds of running sports.
In the flexion direction, the prosthetic lower leg swings through freely up to a flexion angle of about 60°. Even at high stride rates, a harmonious extension stop is ensured by extension damping throughout the entire extension movement, which increases significantly shortly before reaching the end position. Flexion and extension damping can be adjusted separately.
