Modular Knee Joint, pneumatic
The 3R78 knee joint is lightweight yet robust and offers high stance phase safety for users with moderate activity levels. The joint geometry effectively shortens the prosthesis when your leg swings through, giving you more ground clearance. A large flexion angle of 150° also provides greater freedom of movement. The knee joint also supports you when walking at various speeds and is approved for a body weight of up to 100 kilograms.
