Many attempts have been made to restore the function of missing joints as the result of traumatic amputation.  The Power Knee attempts to restore and enhance function by dynamically adding power to the prosthetic knee.  The objective of this study is to examine if functional and clinically relevant differences exist between the C-Leg and the Power Knee for participants with transfemoral amputations ascending ramps and stairs.  Results show no observable differences between peak knee power generation at the intact or the prosthetic knee for amputees ascending a ramp.  However for stair climbing the power generated at the prosthetic knee for amputees using the Power Knee was greater than those using the C-Leg.
