Doctors in England are taking all necessary precautions to prepare for an epidemic this holiday season. Wii knee, they say, is on the rise. Brought on by an obsession with the Nintendo Wii, Wiii knee refers to all Wii-related injuries, typically affecting the elderly and those otherwise not used to moving with such alacrity. After doctors reported an increase in back injuries last year from dads trying to keep up with their Wii-loving children, researchers at Leeds Teaching Hospital diagnosed the first case of Wii knee. Other maladies include smashed fingers, sprained wrists, and broken nails. Dr. Andrew Coley not only treats patients with Wii-related injuries, he is a patient. "I hurt myself by trying to get an Ace on my serve in the tennis game," he said.
