Abstract
According to estimate by the World Health Organisation, 90-95% amputees in the developing countries do not receive a prosthetic device and only 20% of amputees are able to afford currently available prosthetics in the market. Unfortunately, millions fall below the poverty line and do have access to proper prosthesis care. The aim of my project is to design a 3D printable prosthetic knee joint that is cheap and made of relatively less expensive material. The concept is to utilise 4-bar mechanism to transfer hip moment to the leg and thereby produce a gait cycle that mimics human gait cycle. Yes the design does lack some of the features present in the high-end prosthetics and requires a lot of improvements in the fields of ergonomics, aesthetics and functionality before it can be used by an amputee, but it is something that is workable and most importantly it is cheap. In the near future to come the project will have a huge impact in third world countries.
