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.\n\n== Detailed description of the solution ==\n\nThe 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.\n\n== Designed by ==\n\n* Designed by: Joel Sadler and team of classmates from a design course at Stanford University.\n\n== When and where it was tested/implemented ==\n\nThe 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.\n\n== References ==\n\n=== Internally generated reports ===\n\nStober, D.
