VGK-S (Very Good Knee-Short), manufactured by Orthomobiliy, is specifically designed to support the amputee developing mobility with a rather short residual limb (stump). The compact hydraulic cylinder powered by a “Polykinetic Processor” is less weight and the innovative placement of the cylinder makes it the most convenient knee joint for a short stump AK amputee.

Additional features:

  • Hydraulic unit with adaptive fluidic control
  • Safety and stability in stance
  • Swinging freely when sittingy
  • Proximal center of gravity far above the knee axis to minimize the force on the stump
  • Natural knee angle up to 75° flexion
  • Variable and adaptive gait
  • Waterproof
