X2 microprocessor knee gets tested

The US Army is currently testing out a new knee prosthesis known as the X2 microprocessor knee, where it was specially developed in order to provide additional support while giving the lower leg a more natural walking gait. Patients who used the older C-leg had to suffer from knee and joint pain, but once they started off with the new X2, pain relief was more or less almost immediate. Some patients even shared that the X2 has granted them a new ability to run without having to switch to a more specialized prosthesis, which is a good thing. We would like to see the X2 microprocessor knee enter the mainstream market at an affordable price, but could that be one dream too far to pursue?
