Founded in 1971 by Icelandic prosthetist Össur Kristinsson, Össur is one of the world's largest prosthetics manufacturers. Kristinsson — himself a congenital below-knee amputee — invented the first silicone prosthetic liner (the Iceross). The company is now part of Embla Medical, listed on Nasdaq Copenhagen, and employs around 3,000 people across 25+ countries. Its prosthetics portfolio spans bionic and mechanical knees, feet, and upper-limb solutions, including the Rheo Knee, Power Knee, Pro-Flex feet, and the i-Limb hand range.
