Queen star Brian May is recovering after undergoing arthroscopic surgery on his knee.

The guitarist went under the knife on Monday (03Dec12) to repair a "ripped cartilage and other stuff" and he took to Twitter.com on Tuesday (04Dec12) to let fans and followers know he was fine - and to thank them for their good wishes.

He wrote, "I'm out! Alive and almost kickin'!!! Hi folks... thanks so much for your good wishes!! Thanks for all the advice folks - and te (the) sympathy - love the sympathy! Ha ha! I'll soon be kickin' that can. All over the place."

May also posted a photograph of himself in hospital sporting a bandage on his leg.
