With the single-axle modular knee joint 3R80, climbing stairs provides safe and comfortable walking in inclined and hilly areas. This system provides a dynamic soft walking pattern. Suitable for mobility levels 3 and 4. 3R80 provides high security during the stance phase.

When the prosthesis makes a heel strike, it prevents sudden knee bending thanks to the hydraulic safety. The hydraulic safety system is only available in 3R80. Both the stance and the swing phase are controlled by this system. When the load placed on the prosthesis is removed, the knee joint immediately takes the position of the swing phase. It provides automatic adaptation to your speed. 3R80 body weight is suitable for up to 100 kg.
