Adding to the list of growing Wii injury “epidemics”, doctor’s in the United Kingdom have warned new holiday Wii owners to take it easy, lest they get “Wii Knee”.

Researchers at the Leeds Teaching Hospital said that playing too much Wii can cause “painful strains and fractures” in all areas of the body, just not the knees.

Richard MIlner of the British Society for Surgery of the Hand (BSSH) said that he had treated many more “Wii injuries” in the past year.

“We treated a patient this week who had injured herself using a Wii. She was playing tennis with a partner and fractured one of the bones in her finger when he hit the back of her hand with the control,” Milner said.

Another doctor, Andrew Coley, said he had treated a patient that had played the Wii for too long. “This patient had got a Wii for Christmas, hadn’t exercised in a while and overdid it,” Coley said. Apparently the good doctor also got too excited playing the Wii, saying that he “hurt [him]self by trying to get an Ace on [his] serve in the tennis game.”
