Umar who is on the payroll of Turkish club Rizespor sustained the career threatened injury while in action for the club.
The surgery was carried out at the Acidadem Falys Hospital as the surgeon Omer Taser said the surgery was successful.
The club have now announced that they are not expecting the former Wikki Tourists man to return to the pitch until after six months.
