Strootman will be sidelined for at least six months and will miss this summer's World Cup in Brazil.
A statement from Totti, on his official website, read: "Strength Kevin!
"All you have to do now is to think about your recovery.
"I know you will do so with the same determination that you show each time you go out on the pitch.
"We will wait for you and I can't wait to organise a dinner to celebrate your return."
