Indian Institute of Technology Madras Researchers have launched India’s first indigenously developed Polycentric Prosthetic Knee, which aims to improve the quality of life for thousands of above-knee amputees.

Called ‘Kadam,’ this ‘Made in India’ product makes it possible for above-knee amputees to walk with a comfortable gait. Not just mobility, it also aims to improve the quality of life of users through increased community participation, access to education, livelihood opportunities and overall well-being.

“The need for Technology to meet health and medicine is crucial for a healthy future.  The Kadam is yet another example to justify this need.  We, at IIT Madras are very happy that our Research and Development efforts are translating to products that could be of benefit to mankind,” said Prof. V. Kamakoti, Director, IIT Madras.

Kadam has advantages over a hinge joint because of the multiple axes of rotation, which provide the user greater control over the prosthesis while walking and maximum knee flexion of 160 degrees to make it easy to sit in cramped spaces like buses and autos.

It is designed for durability with high strength stainless steel and aluminium alloy along with hard chrome plated EN8 pins and high fatigue life polymer bushings.

Indigenously developed Kadam is affordable and at the same time, of high quality and performance, complying with ISO 10328 standards including 30 lakh cycles of fatigue testing.
