No word on return timeframe
Stackhouse had surgery Tuesday in New York to relieve soreness he has felt since the final weeks of last season. He has been diagnosed with a condition that has deteriorated the lining on the back of his kneecap.
No ligament damage was found during the operation.
"They performed the necessary procedures to address the discomfort in Jerry's knee," Wizards president Ernie Grunfeld said. "Jerry is a very competitive person, and I know he will do everything he can to rehab in the most efficient and effective way possible and get back to help his teammates in any way he can."
Stackhouse will likely start the regular season on the injured list, meaning he will miss at least five games.
Stackhouse led the Wizards in scoring last season, averaging 21.5 points. He recently signed a contract worth $33 million over the next four seasons.
