Veteran rocker Brian May has thanked fans for their messages of support as he recovers after undergoing knee replacement surgery on Tuesday (06Aug13).

The Queen star checked into hospital for an operation to fix a chronic problem which has plagued him for some time, and he sent a message to his followers just hours after the surgery to inform them it had been a success.

In a message posted on the social networking website, he writes, "I'm through!!! With a shiny new knee. This no walk in the park (!) but for 1st time in months I feel optimistic and free of that Old pain."

May, 66, also thanked his loyal fans for cheering him up after the operation, adding, "Thanks so much for the great messages - it means a lot."
