The newly re-designed 3R80 allows for a dynamic, smooth gait pattern for a large range of walking speeds.The wearer has confidence in the knee as it offers rotary hydraulics to control stance and swing phase. The rotary hydraulics of the 3R80 respond to the ground reaction forces in the stance phase at every step - high hydraulic resistance, which prevents involuntary flexion of the joint.
The level of resistance in stance phase can be adapted to the requirements of the user, and enables unlimited knee flexion under load.
The manual lock allows for safety and comfort, such as during long periods of standing or walking in water. The user can easily activate/deactivate the lock by pushing a small lateral lever down/up while the prosthesis is loaded on the forefoot


  • Revision to the hydraulic swing phase control creates a whole new experience for the user

  • The user needs considerably less effort to initiate flexion of the knee for swing phase than with the original model

  • Waterproof

  • Manual lock

  • Available in both pyramid version and screw top version

  • Rotary hydraulics control stance and swing phase

  • High hydraulic resistance – to prevent involuntary flexion of the joint
