Joe Riffe is Kentucky's only amputee paramedic, thanks to an advanced prosthetic leg that uses similar technology to the Wii gaming system and smartphones. Riffe’s leg was amputated above the knee after a fall during a hike in 2011 that left his knee and ankle too badly damaged to repair. He was able to go back to being a paramedic seven months after receiving the leg, which uses four sensors and three microprocessors. "[I]t thinks ahead of me so whatever move I make ... it moves with me,” Riffe said.
