"First of all, thank you for all the support and love," Ibrahimovic, United's top scorer this season with 28 goals, wrote on his Instagram account on Sunday.
"It's no news I got injured so I will be out of football for a while. I will go through this like everything else and come back even stronger. So far I played with one leg so it shouldn't be any problem."
The 35-year-old Swede, whose contract at Old Trafford expires at the end of the season, said injuries will not decide his future in the game.
"One thing is for sure, I decide when it's time to stop and nothing else. Giving up is not an option," he added.
