"New Thanksgiving tradition 🦃 ❄️," Shields, 56, wrote in the caption of the video.

Her friend, Ali Wentworth, commented with, "You're supposed to cook the Turkey not yourself…"

Shields appeared to walk fine after recovering from a broken femur that later turned into a staph infection.

The actress told PEOPLE earlier this month that she refused to take any painkillers during her recovery out of concern that she would form a reliance on opioids like OxyContin or Vicodin.

"I didn't want to leave the hospital with no pain, get home, and think I was dying, because the pain was excruciating," she said. "I was like, 'I'd rather have excruciating pain in the hospital.'"

Shields also wanted to make sure that over the course of her recovery, she was able to recognize the difference between the pain from her original injury and anything new that could crop up.
