Nope, never will be, 12 months after surgery they diagnosed 23% loss of use and the only option was a second surgery with no guarantee they could fix it. 10  years on I'm down to 27% loss. I doesn't often stop me doing things but I can't keep my arm raise above horizontal for more than a few minutes and when I do push it too much I really pay for it.
I thought they were still on tour with BLS but surely there is no way he'd be scheduling surgery if that was the case because he's looking at several months of rehab before he can even walk properly after a full knee replacement and that's if all goes well.
