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 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.
Three Generations Of ReMotion
Students at Stanford University developed the v1 ReMotion JaipurKnee for production and fitting by the JaipurFoot Organization, the largest provider of prosthetics in India and the world.
The v2 ReMotion Knee was manufactured in Menlo Park and distributed through Fundación Protesis Para la Vida in Ibarra, Ecuador.
The v3 ReMotion Knee is our first version that is designed to be mass produced for world-wide scale.
