• "This knee joint, weighing less than one kilo - and doing all the functions that my MPK did - gives me the independence and self-determination I need for myself and my job." The VGK-S reflects a new way of thinking about amputee healthcare - in particular, amputees with short transfemoral stumps. An estimated 30% of amputees have femoral bone length that is too short to handle the mass distribution of a standard prosthesis comfortably. The VGK-S represents a bespoke innovation for short transfemoral stumps that allows space for a functional prosthetic component. Some call it an upside down knee joint (which it isn't), but this idea reflects the revolutionary approach this knee takes and the fact that there isn't anything else like it. This knee effectively replaces the quadriceps that are lost during amputation. You can read testimonials from amputees using the VGK-S here!
  • VGK knees provide intuitive control to patients. This control allows patients to live without barriers. The VGK's patented hydraulic fluid technology ensures the knee stays in stance mode at all times, except when the knee enters swing phase. When the knee commences extension, the hydraulic fluid system immediately switches to stance mode, allowing the knee to recover from stumbles or walk downhill. This system uses the actual speed of movement of the fluids inside as a source of energy and information for adjusting resistance, keeping the rate of movement within comfortable boundaries.
