The Hollywood star, 89, was left with several fractures to her hip and and a series fracture to her femur after she fell in the bathroom of her home this weekend.
Sophia's sons, Carlo Jr., 55, and Edoardo, 50, have been by her side throughout the ordeal and her time in hospital, according to The Hollywood Reporter.
News about Sophia's condition was shared by the team at her self-titled restaurant chain, who shared the news on their Instagram page.
The statement read: 'A fall at her home in Geneva today caused Ms Loren hip fractures. Operated with a positive outcome, she will now have to observe a short period of recovery and follow a road to rehabilitation.
'Thankfully everything worked out for the best and the Lady will be back with us very soon. The whole team at Sophia Loren Restaurant takes this opportunity to wish her a speedy recovery.'
The post announcing Sophia's surgery news was flooded with support from her devoted fans, wishing the star a speedy recovery.
Sophia had been due to open a fourth branch of her restaurant chain in Bari, Italy, on Tuesday. The Italian native was also due to receive honorary citizenship from the city.
