The 49-year-old actor is on bed rest for four days after the operation yesterday.
SRK, who was shooting for Rahul Dholakia's "Raees" despite the pain, took to Twitter today to thank his fans for their well wishes.
"Do they do Frequent Fliers Miles in Hospitals? If yes, I would own some of the hospitals! Thanks all for standing by me as I pray on my knees...," Shah Rukh joked while referring to his previous hospital visits.
Sanjay Desai, who operated on the "Happy New Year" star, said, "SRK has undergone Arthroscopic surgery of left knee at Breach Candy Hospital. Khan has been suffering from repeated pain and swelling of left knee over the last several months... He has recovered well..."
The actor has suffered many injuries in the past. During the promotion of Farah Khan's "Happy New Year" last year, he had hurt his knee. He shot Yash Raj's "Fan" despite health issues.
