The company began as a small and prosthetics (O&P) , initially focused on producing basic orthopedic devices to address mobility challenges for local patients. Kristinsson, who trained as a certified prosthetist-orthotist in , established the clinic to apply his expertise directly in patient care and device fabrication. A pivotal early innovation came in the 1970s when Kristinsson developed the Iceross® interface for prosthetic sockets, inspired by his own experiences with limb prosthetics. This roll-on liner represented a breakthrough in socket suspension, utilizing a hydrostatic principle to create total surface contact between the residual limb and the socket. Custom-made versions of the Iceross® socket emerged in the early 1980s, with prefabricated models entering use in by early 1986 and receiving global patent protection that same year. The Iceross® technology revolutionized prosthetic comfort and fit by evenly distributing pressure, stabilizing soft tissues, and minimizing vertical pistoning and shear forces that often caused skin irritation and discomfort. This approach eliminated the need for additional liners or straps, enabling improved and reducing the risk of tissue damage during daily activities. By prioritizing such advancements, Össur shifted the from rigid, limited-contact sockets to more adaptive, patient-centered designs. From its start, Össur placed a strong emphasis on non-invasive orthopedics, beginning with simple braces and supports for stability and progressing to advanced prosthetic components by the 1980s.
