Global Need For Prosthetics

The Need

In the developing world, trauma, disease, and natural disasters result in hundreds of thousands of new amputees per year.

For amputees in low-resource settings, modern prosthetics are prohibitively expensive, typically costing thousands of dollars or more. Even if an amputee is able to pay, most likely they do not have access to a prosthetics clinic that fits their needs.

Existing, low-cost knees present significant limitations to mobility

If available, affordable prosthetic leg systems typically use single-axis knee joints—similar to a door hinge. While walking, particularly on rough terrain, single-axis knee joints are unstable and can buckle, leading to a sudden and dangerous loss of balance.

The Delivery

Delivering the ReMotion Knee to clinics and amputees in the developing world.

The ReMotion Knee is a low-cost and high-performance knee joint, but that is not the end of the road for mobility. Although the knee joint is typically the most expensive and complex component, a full prosthesis also contains a foot, a pylon, and a socket. A trained clinician must custom mold the socket to fit the patient and assemble it with the other components, which is why it is so important for D-Rev to partner with clinics around the world that are staffed with prosthetics experts.

To accelerate the ReMotion Knee’s impact, D-Rev is creating partnerships and sales with top-tier prosthetic providers worldwide with already established distribution channels and local expertise. By partnering with D-Rev, prosthetic clinics gain access to world-class design and engineering capabilities while continuing to provide in-depth patient care.

The story of Dinesh, a young Indian amputee, who was fit with D-Rev's ReMotion Knee in March 2013.

Kamal in Motion

At the age of 16, Kamal lost his left leg in a motorcycle accident. Unable to afford a prosthetic limb, he used a bamboo staff to get around, leaving his hands callused and his spine misaligned. In August of 2008, Kamal was fit with a JaipurKnee and within a day, was able to walk.
