Dr. Richard Steadman planned to go in and evaluate the strength of the joint. When he was looking, he determined the cartilage in the knee was unstable and went through with microfracture surgery.
"We were hoping that he wouldn't have to have the microfracture surgery, but this is what's going to be best for him," manager Manny Acta said. "This is what's going to give him a chance to play longer, probably for the next 10 years, and be as healthy as he can. What's good for him is good for us. Everybody knows over the last six or seven years what Grady represents to this ballclub."
The surgery generally has a six- to nine-month recovery window, meaning that Sizemore should be back during Spring Training 2011. Sizemore is expected to have a full recovery.
"Grady also said, 'I want to have one knee operation,'" trainer Lonnie Soloff said. "Grady will be back in Cleveland on Thursday."
