Bollywood star Khan in hospital

The star injured his shoulder further while filming in December

Bollywood star Shah Rukh Khan has undergone surgery on his shoulder at a Mumbai hospital for an injury which he suffered during filming last year.

The 43-year-old, popularly known as King Khan, was hurt while acting in the movie Dulha Mil Gaya (I Found my Groom) in December 2008.

Surgeon Sanjay Desai said the star is recovering but will be out of action for "four to six weeks."

Khan is expected to be discharged by the end of the week.

"He is out of anaesthesia and is a bit groggy, but otherwise the situation is under control," Desai, who led a team of doctors operating on Khan, told reporters after the 90-minute operation.

Khan injured his shoulder a while ago, but the condition was aggravated in December.

His surgery had been postponed due to his movie commitments and he underwent physiotherapy sessions.

Doctors said Khan was advised to undergo surgery only because he was keen to do action roles and perform stunts himself.

"If he were to lead a sedentary life, there would be no need of the surgery," the actor's physiotherapist Ali Irani said.

Speaking before he went into hospital, Khan said: "I think when you are working in this kind of field where you have to run, jump and fall, after 20 years it's just natural to get these ailments."

Khan's latest film, Billu, opened in cinemas in India last week.
