December, 2013.  Here is a video showing a new prosthetic knee that is able to serve high function and is also very affordable at only $80.  While most above the knee prosthetics are being worn after a six months period 60% of the time, this new cheaper prosthetic knee is at a much higher 79%.  This shows that the prosthetic leg is more comfortable, and more stable at a much better price.  Being so affordable, this knee gives amputees living in poor countries the chance to have a high functioning prosthetic leg.
