Actor Mahesh Babu, who left for New York for a three-month family vacation, has decided to undergo knee surgery to treat an injury he sustained during filming of Aagadu in 2014. According to a source, he has been suffering from acute knee pain for the past few years.

"Mahesh had sustained a knee injury while shooting for the title song of Aagadu in Bellary and has been delaying the surgical procedure due to his hectic work schedule. Even though he contemplated surgery after SPYder (2017), things didn't work out as he did not want to be away from all the action for a long period. Now that he has completed the promotional activities of his latest release Sarileru Neekevvaru, he has decided to go under the knife in USA," says a source.

The surgery has been scheduled to take place in the last week of January and it will take at least five months for the actor to recover completely.

Mahesh will next team up with his Maharshi director Vamshi Paidipally for a slick action thriller. Produced by Dil Raju, the film will see him playing a secret agent and is expected to go on floors in July.
