Quite a lot of heads turned at Sahar Airport on Saturday night, when Sanjay Dutt returned from his European holiday.

The 51-year-old actor took everyone by surprise when he hobbled with a walking stick.
According to Mumbai Mirror, Sanjay Dutt has undergone a knee surgery in Germany.
Sources close to the actor confirmed the news saying, “From Paris, Dutt took off to Germany for a few days, where the knee surgery was carried out. He had booked a doctor much before he left Mumbai. It was well planned, and kept under wraps.”
Dutt's knee problem apparently surfaced during the shoot of Anthony D'Souza's Blue (2009). Though the film sank without a trace, Dutt's knee issues rose up; in fact it continued to resurface every now and then, causing him immense discomfort and pain especially during stunt sequences.
A friend of Dutt called up to say, “Dutt has had a packed couple of years and is extremely overworked. He needed some rest. He combined this with the knee treatment. Let's hope it doesn't recur again. He will start shooting in Hyderabad at Ramoji rao for remake of the Tamil movie Saamy from August 25.”
