• India’s first indigenously developed polycentric prosthetic knee – Kadam was launched by the Indian Institute of Technology, Madras (IIT-M), the Above Knee Prosthesis was developed in association with Society for Biomedical Technology (SBMT) and Mobility India.
• Kadam will help people with above-knee amputees to walk in comfortable gait.
• Kadam has multiple axes hinge joints for rotation which provide greater control over the prosthesis and gives a maximum knee flexion of 160 degrees to make it easy to sit in cramped spaces like buses and autos.
• The design includes high durable stainless steel and aluminium alloy along with hard chrome plated EN8 pins and high fatigue life polymer bushings, which was developed by a team at TTK Centre for Rehabilitation Research and Device Development (R2D2) at IIT-M.
• The Kadam prosthetic knee is suitable for both short and long residual limbs after transfemoral (above-knee) amputation and comes with a patented 4-bar geometry that provides stability even on uneven terrain and improved ground clearance.
