  2. Addressing the Problem • Over 25 million people in the world today are suffering from the loss of a limb • Amputees looking to replace a missing limb turn to modern prosthetics • Today’s prosthetics are unaffordable, leaving people around the world hopeless

  3. Costs • Partial foot ($14,187) • Ankle disarticulation ($16,356) • Hip ($45,633) • Transpelvic disarticulation ($49,208) • Transtibial, or below the knee ($16,690) • Knee joint ($45,563) Most expensive and complex portion of a prosthetic leg http://healthcaresavvy.wbur.org/2013/04/the-cost-of-prosthetics/

  4. Who can afford it? • Out of the 25 million people in the world suffering from the loss of a limb, only about 20% can afford the necessary prosthetics • Amputees in third world countries do not have the money or resources for modern prosthetics • Each year, disease and trauma in war torn areas of the world leave thousands of new, less fortunate amputees

  5. Making affordable prosthetics… • Today’s existing “affordable” prosthetics are limiting • Affordable leg prosthetics operate on a single-axis hinge system • On rough terrain, single-axis hinges tend to be unstable and can even buckle at times • Most affordable knee prosthetics used in the last ten years have been unsuccessful

  6. What’s Needed • The ideal prosthetic knee joint: • Lightweight • Durable • High range of mobility • Affordable • Simple

  7. A Real Solution • The JaipurKnee • Designed in collaboration with Stanford University and the Jaipur Foot Organization

  9. Specifics of the JaipurKnee • Lightweight; 1.5 lbs • Durable; oil-filled nylon polymer self lubricates! • 165 degrees of motion; bending/kneeling • Works with standard prosthetic systems • Bench top tested for 3-5 years of use

  10. Impact • 4,977 patients have been fit with ReMotion'sJaipurKnee • 79% of these patients are still wearing their prostheses • 95% of patients report no failures in their JaipurKnees
