Knee joint, monocentric, with rotation hydraulics

As someone with a prosthesis, confidence in your knee joint throughout daily activities is key. That's why we've been dedicated to developing a knee joint that makes you feel supported and independent in every day life. The 3R80 features unique rotation hydraulics that allows both the stance and swing phase to be controlled by the hydraulics. For example, walking down stairs step-over-step and walking down inclines at various walking speeds are supported by the joint that closely mimics the physiological gait pattern. Additionally, the knee is now approved for users up to 330 lbs, has a manual lock for increased safety, and is water-resistant to a depth of 3 meters.
