The team said Granger had the procedure Thursday. A full recovery is expected and Granger is expected to be ready for training camp this fall.
Granger missed the first half of the season with patellar tendinosis after undergoing a second injection to treat the injury in October. He returned for five games in February, but the injury flared up and he didn't play again.
Entering Thursday's games, the Pacers had a seven-game lead in the Central Division and were third in the Eastern Conference.
