The single axis hydraulic knee Hytrek is convenient for everyday situations as well as more sustained activities.

The hydraulic regulation provides a dynamic control of the swing phase (Extension terminal impact and flexion dampening). The advantage of an hydraulic regulation knee is to dampen the lower leg during swing phase and to provide resistance to flexion during stance phase when going down slopes or stairs

The Hytrek knee includes a hydraulic unit. It allows the patient to walk easily, at variable speed.

When the patient is walking, the valve regulates the hydraulic fluid, which limits flexion.
