Miami Heat guard Dwyane Wade underwent surgery on his left knee Monday morning, and told ESPN's Rachel Nichols that the procedure went well.

Wade had the knee scoped and said that doctors did not find anything unexpected. His knee had been bothering him throughout the season, and he played with pain during the playoffs. Recovery time is six to eight weeks.

Heat team physician Harlan Selesnick performed the operation, which took approximately 20 minutes, at Doctors Hospital in Coral Gables, just outside of Miami.

Wade was bothered by knee pain and swelling throughout the playoffs. He had fluid removed midway through Miami's second-round series with Indiana and needed treatment several times a week during Miami's run to the title.

Wade played in all 23 Heat playoff games despite the knee problems. The eight-time All-Star is expected to be ready for the start of training camp and wrote on his Twitter page Monday afternoon that he is "doing fine."

Surgery means Wade will miss the London Olympics. Wade had surgery on his left knee in May 2007. He led the Americans in scoring at the Beijing Olympics, averaging 16 points despite coming off the bench in all eight games.
