The Hawks say Tuesday's surgery was performed in New York by Dr. David Altchek.
It is the third surgery since March for the 34-year-old Korver, the team's starting shooting guard and 3-point specialist. He had surgery for a broken nose three months ago, and earlier this month surgeons repaired ligament damage in his right ankle.
He was still wearing a walking boot when he helped the team introduce its new uniforms last week.
The Hawks also officially announced two new titles reported last week: Coach Mike Budenholzer was named president of basketball operations and Wes Wilcox was promoted to general manager.
