The recovery time will be anywhere from four weeks to four months, Kemp said, depending on what doctors find during the procedure.
"They'll cut it open and see what's going on inside of there," Kemp said. "Hopefully, they just clean it up. If they need to do more, they'll do more, but I won't know anything until I wake up."
Kemp injured his shoulder smacking into the outfield wall against the Rockies in Colorado on Aug. 28. Before the injury, he was batting .337 with a .584 slugging percentage. After it, he batted .218 with a .427 slugging percentage.
Kemp said he was planning to play on Team USA in the World Baseball Classic next spring, but won't now.
"I think we can throw that out the window," Kemp said.
Kemp finished second to Ryan Braun in MVP balloting in 2011, when he batted .324 and led the league in home runs and RBIs. He missed 51 games earlier in the season with hamstring injuries, but never went on the disabled list for the shoulder injury.
Kemp finished the season on Wednesday night in an 0-for-10 slump. He batted .303 with 23 home runs and 69 RBIs.
The Dodgers had better news regarding ace Clayton Kershaw, saying the left-hander won't require surgery for a hip injury that caused him to miss two starts in September.
Kershaw finished the season 14-9 with a major league-best 2.53 ERA. He got the win in the Dodgers' 5-1 victory over the San Francisco Giants on Wednesday night.
