1.1 Construction and Function

The 3R80* Prosthetic Knee Joint is a monocentric prosthetic knee joint with rotation hydraulics
and a mechanically controlled stance phase stabilisation system. It is waterproof and equipped
with a manually operated lock. The prosthetic knee joint has a pyramid adapter (3R80) or
threaded connector (3R80=ST) as the proximal connection.
The integrated rotation hydraulics control the swing phase and secure the stance phase. Damp­
ing for flexion, extension and the stance phase are individually adjustable. This allows comfortable
walking over a broad range of speeds.
Stance phase damping is activated when bearing weight on the prosthesis. The activation
threshold is adjustable. It provides for stance phase flexion up to 4° while bouncing, and more
than 4° while yielding. Walking on slopes and down stairs step-over-step is therefore possible.
An extension assist spring supports the swing phase by generating an extension moment. The
additional spring included in the scope of delivery can be installed to increase the extension
moment.
The lock keeps the prosthetic knee joint at full extension. This function is suitable for situations
where flexion is to be prevented (e.g. when standing for extended periods of time or wading
through water).
