LIFE AND LIMB: Double amputee Greg Gadson tries out his new power knees at the Walter Reed Army Medical Center in Washington.
Gadson -- whose bravery helped inspire the New York Giants to their last Super Bowl victory -- recently became the first person in the world to land a pair of super-high-tech prosthetic legs that practically think for themselves.
Gadson -- who lost both legs above the knee when his convoy was hit by a roadside bomb two years ago -- has been fitted with the Power Knee, a revolutionary, battery-powered prosthetic developed by Icelandic company Ossur.
"[The prosthetic's] intelligent," Gadson said last week from his home in Virginia. "It gauges my weight, my speed . . . It's the closest thing to normal legs that I've experienced.
"The difference is if you're walking on a normal prosthetic and you step in a pothole in the street, you're going to fall. With this, it's going to accommodate that.
