Surgeon Dr. Sakari Orava says Beckham "is doing well" and that Monday's operation lasted just under an hour at the clinic in Turku, southwestern Finland.
Orava says Beckham "will have to take it very easy during the next two to three weeks or a month and then he will continue with a recuperation program slowly."
He says the foot won't be able to "take much strain" for up to three months.
The 34-year-old former England captain was injured in the closing minutes of AC Milan's 1-0 win over Chievo Verona on Sunday.
