The RNOH and the Royal Orthopaedic hospital in Birmingham just finished its first set of trials in July, where they implanted ITAPs into 20 above-the-knee amputees. Many of the testers reported a better quality of life ever since getting the prosthetic. Mark O'Leary, who got his ITAP implant in 2008, says he can feel everything with the limb and has even conquered Mount Kilimanjaro, among other mountains and hiking spots, since then. You'll seriously feel lazy once you read up on his adventures.

It'll take another 12 to 18 months before the researchers and ITAP's manufacturer, Stanford Implants, can get the trial's results. If successful, ITAP will be deployed to more hospitals across the UK. Sadly, it still has to get the FDA's approval before it can make its way stateside and be of use to many veterans and other American amputees.
