Rodgers confirmed to ESPN.com on Friday night that he had the surgery following the 26-20 divisional-round overtime loss on Jan. 16.
This injury prompted Rodgers to pull out of Sunday's Pro Bowl.
An ESPN source described the surgery as a minor scope and a "cleanup of an old injury." Rodgers told ESPN that he is "doing well" and "recovering on schedule."
The following week after the Lions game, the Packers listed Rodgers on the injury report with an unspecified shoulder problem but not for his knee.
Rodgers' production dropped in 2015, setting career lows for completion percentage (60.7), passing yards per game (238.8) and yards per attempt (6.7). Eight interceptions represented his highest total since 2012.
Rodgers, 32, had reconstructive surgery on his left knee in January 2004 -- his first season at the University of California -- for an injury suffered earlier while playing basketball in high school.
