6-bar knee with Stance Flex

• The polycentric, 6-bar design delivers enhanced geometrical safety in the stance phase. The hydraulic cylinder facilitates the transition to the swing phase and is responsive to variations in walking speed.

• Stance Flex function: the knee preflexes as soon as the heel strikes the ground and maintains this flexion thru to the midstance phase. This absorbs the impact at heel strike and reduces the displacement of the center of mass.

• As soon as the knee is loaded, it switches to secure mode.
