Actua Hydraulic K3 Knee


Polycentric Hydraulic Knee with Stance Flexion and Extension Assist

The Actua Hydraulic Knee is a polycentric hydraulic knee joint with stance flexion and interchangeable spring extension assist. The stance flexion can be tuned infinitely, which ensures optimal comfort during loading response.

Swing Adjustment
The swing performance can be adjusted via two set screws (“F” for flexion / “E” for extension) on each side of the knee, respectively.
