The purpose of the procedure was to "trim small piece of cartilage in his right elbow" and Wainwright will start physical therapy in two weeks and begin throwing in eight weeks, according to the team.
Cardinals general manager John Mozeliak said Monday, following an exam on Wainwright's elbow, that Wainwright should have a "normal offseason."
Wainwright, 33, acknowledged in August that he was dealing with a dead arm. The 6-foot-7 right-hander pitched well in September, allowing one run or fewer in four of his five starts.
Wainwright didn't have as much success in the postseason, with only one of his three starts lasting at least five innings. The Cardinals fell to the San Francisco Giants in the National League Championship Series in five games.
Over 227 innings this season, his ninth in the league, Wainwright posted a 2.38 ERA with 179 strikeouts, 50 walks and a 1.031 WHIP en route to his third All-Star appearance.
Wainwright missed the 2011 season after undergoing Tommy John surgery on his right elbow.
