According to one of Zsa Zsa's doctors, three quarters of her leg was removed during the surgery today -- starting from just above her knee.
We're told there were no unexpected difficulties and she's expected to heal just fine -- but docs are monitoring her closely because of her age.
As we previously reported Zsa Zsa's husband, Prince Frederic von Anhalt, green-lit the procedure to remove a life-threatening infection.
No word yet on when she'll be released.
