Avenged Sevenfold frontman M. Shadows has undergone surgery to his knee so he can continue rocking out onstage.
The vocalist was frequently forced to wear knee braces and hobble around during concerts because a joint problem left him in agony.
Now he's revealed he had an operation earlier this year (11) to correct the condition - and he's delighted his performances are no longer hindered by his painful patella.
The rocker tells Kerrang! magazine, "I had knee surgery because I was in pain all the time; I was wearing knee braces onstage. But finally it's fixed."
