for the person asking about knee surgeon's in London

I would highly recommend Rhidian Thomas who is based in a clinic down in Wimbledon - I have referred a lot of paitents down to him, and a lot of good feedback about him. Met him a few times, really good guy. Wimbledon Clinics for Musculoskeletal Disorders

There is also Fares Haddad, - he did an operation on an Australian 400m hurdler Jana Pittman a few years ago - I think he's around Baker St.

I find the ones near central london to be in general better, than the ones working further out.
