Last week, City manager Pep Guardiola said that the club's top goalscorer had sustained the problem during the fixture against Manchester United before being unable to run after an outing from the bench against Liverpool in the Champions League.
Aguero was absent at the weekend as City defeated Tottenham Hotspur at Wembley Stadium, and it appears that the Argentine is likely to remain sidelined for the club's upcoming fixtures.
On Tuesday afternoon, Aguero took to social media to say that he was focused on returning to action after undergoing a procedure on the issue.
Recuperándome de una artroscopia en la rodilla. Y con toda la fuerza para volver pronto y mejor a las canchas 💪//Recovering from an arthroscopy on my knee. Fully motivated to get back soon to the field 💪— Sergio Kun Aguero (@aguerosergiokun) April 17, 2018
Aguero will hope to return before the end of the campaign in order to prove his fitness ahead of this summer's World Cup.
