Mapping user needs for a functional prosthetic knee joint: A sociocultural perspective

About this project

The aim of this project is to improve the lives of lower limb amputees, and their families and communities. The specific objective will be to understand the specific needs of amputees in relation to lower limb prostheses.

80% of the world's amputees do not have access to modern prosthetics. For amputees in low-resource settings, modern prosthetics are prohibitively expensive. Existing, low-cost prostheses present significant limitations to mobility as they 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.
