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. The patented horizontal hydraulic cylinder contributes to the compact size of this hydraulic knee joint. In addition, maintenance is easy with the innovative oil-refill system.

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.
