The Manchester City striker had the operation on Tuesday and the English club said he would likely miss the rest of the season.
The knee surgery means Aguero will not play again this season but the Citizens were crowned Premier Champions on Sunday when bottom side West Brom pulled off an unlikely victory over second-placed Manchester United.
Manchester City striker, Sergio Aguero has undergone a minor knee surgery due to an injury sustained in a heavy tackle from Manchester United full-back Ashley Young.
Details into his injury have not been disclosed and a recovery time is not yet set. ESPN's Mark Ogden and Jonathan Smith discuss whether Pep Guardiola can break even more league records after Manchester City won the Premier League.
Aguero will be eager to make up for Argentina's 2014 World Cup final heartache in Russian Federation this summer.
"I imagine that he will not arrive 100 per cent fit with the limited time that is left before the World Cup". He can try but I don't think he will arrive 100 per cent.
"The important thing is to know what he had".
Having seen City win the Premier League with five games to spare at the weekend, the 29-year-old made a decision to have the operation immediately in order to give him enough time to recover ahead of the tournament.
