Nnenenenenene....or something like that anyway. You remember the sound the Six Million Man makes when his bionic parts are working. Ossur has a bionic knee that replaces the natural knee of those who loose lower limbs. The knee uses an magnetorheological fluid to learn the way the wearer walks, making for a more natural gait. The knee is powered by rechargeable batteries, no doubt soon the phrase "darn I forgot to recharge my knee" will be uttered somewhere.
