James Edward Hanger was a civil war amputee who invented the first prosthetic knee device. He was then commissioned by the government to make prosthetic limbs for wounded soldiers. 150 years later, the orthotic and prosthetic company Hanger treats more than 1 million patients each year. Vinit Asar, President and CEO of Hanger, and Cameron Clapp, a patient advocate for Hanger, tell Cheddar how Hanger is disrupting the orthotic and prosthetic market.
