1 Affordable Knee Replacement Joshua Powers JaipurKnee: a high-performance knee joint for developing world amputees

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 Todays 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

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… Todays 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 Whats Needed The ideal prosthetic knee joint: – Lightweight – Durable – High range of mobility – Affordable – Simple
