3R80 - Knee prosthetics

Knee joint, monocentric, with rotation hydraulics

Show your determination.

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.

With the market launch of the Genium leg prosthesis in 2011, Ottobock opened up entirely new horizons for prosthesis wearers: an unprecedented, natural gait pattern, climbing stairs step-over-step, overcoming obstacles, walking backwards, relaxed standing – to name just a few. For the first time, people with a transfemoral amputation experienced a range of new functions that provided perfect support for their desire to live a more active and independent everyday life.Based on human movement as the model, the Genium has been developed even further. The result is a noticeably smoother gait and even better support and safety in everyday situations, for instance on ramps, in confined spaces, or when changing walking speeds.
