Modern prosthetics technologies seem to bring out innovations every day to the benefit of the less fortunate ones. Ossur, a leader in non-invasive orthopedics, announced the release of the second generation of the Power Knee, the world's first powered bionic prosthesis for above-knee amputees.

The technology uses sensors, power, artificial intelligence and actuators to provide amputees with the ability to lead a normal life by walking naturally and safely. The Power Knee was introduced back in 2006, working in partnership with Victhom Human Bionics. Mainly used by the Department of Defense and the Veterans Healthcare Administration, it represented a milestone in amputee mobility.

"The second generation is smaller, sleeker, quieter, lighter and is expected to become widely used by both unilateral and dual amputees," stated Lt. Col. (Dr.) Paul F. Pasquina, chief, Integrated Department of Orthopedics and Rehabilitation at Walter Reed and the National Naval Medical Center.

The first person in the world to be fitted with the new version of the prosthetic knees is Lieutenant Colonel Greg Gadson and will soon be followed by other patients at Walter Reed Army Medical Center. Lt. Gadson lost both of his legs in May, 2007, in Baghdad. He was with Second Battalion and 32nd Field Artillery, on his way back from a memorial service held for two of his fellow soldiers when a roadside bomb exploded. Now, he is a role model and a true inspiration for the New York Giants, who credit Gadson for their motivation behind their 2008 Super Bowl success.

When interviewed regarding the adaptation process he's going thorough, Gadson declared that "It's sort of like driving a school bus and then someone puts you in a sports car. You still know how to drive, but it’s quite a different feeling. I just hope this is a path for people to really expand their lives.”
