Looks like the 3 Idiots effect has not really gone past Madhavan.

Not only is he back with the main cast of the film in Raju Hirani’s next, he is currently suffering from a knee injury that he sustained during the shooting of 3 Idiots. In fact, the actor has gone to USA for a surgery on his knee. Maddy was seen walking with the help of crutches before embarking on his journey.
