Problem being addressed[edit | edit source]

There are tens of thousands of amputees living in the developing world. Unfortunately, patients that live in these resource-poor areas and who lose a knee joint have few options. A titanium replacement can cost up to $10,000 and other inexpensive models are too crude to work effectively.

Detailed description of the solution[edit | edit source]

The JaipurKnee is flexible and stable, even on irregular terrain. It is comprised of five pieces of plastic, four nuts and bolts and has self-lubricating, oil-filled nylon. It does not require special tools and only takes a few hours to manufacture.

Designed by[edit | edit source]

  • Designed by: Joel Sadler and team of classmates from a design course at Stanford University.

When and where it was tested/implemented[edit | edit source]

The device costs $20 USD and is more effective than other crude models. It works effectively on rough terrain. It is currently being tested in India with a projected 100,000 devices being distributed in the next three years.
