With 80% of the world’s amputees living in developing countries, there is a profound need for low-cost lower limb prostheses for the developing world. Modern assistive technology has the potential to re-mobilize lower limb amputees, but at a cost typically in the thousands of dollars. Re:Motion Designs is a for-benefit venture that provides high performance, extreme-affordability prosthetics for the 20 Million amputees in the developing world. Our initial product, the JaipurKnee, is a polymer-based polycentric knee joint that can be manufactured for less than $20 USD, and has been featured by Time Magazine, CNN, BusinessWeek and Fast Company as a major innovation of 2009. Compared with existing low-cost prosthetic knee joints, the JaipurKnee provides a new class of stability and gait efficiency for above-knee amputees, and is currently in field trials in India with over 700 patients fitted to date.
