A knee surgeon contacted by CNN said that the surgery shouldn't delay Federer for too long. "His age might put him at slightly more risk, but he's a consummate professional and is old enough to know that if he isn't ready, he'll just have to skip another tournament," Sean Curry, a specialist knee surgeon at London Orthopedic Clinic, told CNN.
