The Stanford-Jaipur Knee
The Stanford-Jaipur Knee is an invention designed by Stanford University, USA, teaming up with the BMVSS team. The Stanford-Jaipur Knee, also known as the Jaipur Knee, mimics normal human gait by providing stability in the amputee’s stance and easy movement.
The Stanford-Jaipur Knee was listed by Time magazine (November 2009 Issue) as one of the 50 Best Inventions of the World in 2009. The Jaipur Knee has also been fitted on over 9,250 patients, and BMVSS has ever since received very positive feedback on the knee in terms of acceptability, compliance, durability, and performance.
The device is based on the polycentric concept and is designed using the four-bar linkage geometry. It is made from oil-impregnated nylon and comprises; an upper and lower body block, two side linkages, and a mid linkage, all held together by four steel bolts. The body blocks have segments for socket and pylon attachment.
