He is in Sardinia filming a television mini-series adaptation of Joseph Heller's novel Catch-22. The injured actor held onto both handrails of a private jet, as he moved slowly up the stairs with his wife, and 1-year-old twins, Ella and Alexander.
On Tuesday, the actor was hit by an oncoming auto - the driver failed to give way to Clooney - while on the Italian island of Sardinia.
With Amal's help, Clooney eased his way off the cart and leaned on an assistant as he walked to the jet.
George was rushed to John Paul II Hospital in the nearby town of Olbia via an ambulance after the crash but was later discharged with minor injuries.
The impact of the crash sent George flying and he subsequently hit a vehicle windscreen head first, causing the glass to shatter, before he was tossed to the ground.
A source told ET that Clooney was going about 60 miles per hour when the Mercedes Benz hit him and that he was thrown about 20 feet in the air. After complaining of "a slight trauma to the pelvis and bruises to one leg and arm", he was hospitalized, where he underwent an MRI, La Nuova reports.
Although he suffered no broken bones, he will need physiotherapy to his knee. Clooney's helmet hit the windshield and broke due to the force of the impact. "George Clooney was treated and released from an Olbia hospital", his rep confirmed to HollywoodLife at the time.
His spokesman Stan Rosenfield said: 'He is recovering at his home and will be fine'.
George Clooney is on the mend after a terrifying scooter accident. It wasn't obvious that it was going to happen for me.
It's unclear if George and Amal Clooney and their children left the island of Sardinia for their home in Italy on Lake Como or their home in the United States.
Viglino admits he recognized Clooney as soon as he took his helmet off.
