VGK-S for short transfemoral amputees
Overview
The VGK-S is the only knee joint designed specifically for the needs of the short transfemoral amputee.
The weight of the prosthesis critical with a short transfemoral amputation because there is less muscle left to move the prosthesis. The VGK-S weighs just under 1 kg. Further, the VGK-S has taken the revolutionary approach to use the space between the end of the residual limb and the knee centre. By positioning the knee much closer to the body, you have more direct control of the knee.
The VGK-S is a Fluidic Processor Knee (FPK), which means high performance without the need for charging. It offers stumble recovery and sophisticated stance and swing phase control, which supports variable walking speeds, leg-over-leg stair descent and use on uneven terrain.
