The team’s head physician, Dr. Christopher Dodson, performed the surgery, described as minor by the team, in Philadelphia.
Covington told reporters last week that an MRI “showed a baby tear” and he didn’t consider his injury to be serious.
Covington is expected to resume basketball activities this summer, the team announced.
The 76ers shut down Covington on March 31. He averaged 12.9 points and 6.5 rebounds in 67 games this season.
76ers coach Brett Brown has said the 2016-17 season was Covington’s best in the NBA, lauding him especially for his defense as “he grew to a level that was respected around the league as a legitimate two-way player.”
