On Sunday, the 44-year-old CNN anchor was horseback riding in Brewster, N.Y., with her daughters, Sofia and Cecilia, when she was thrown from her horse.
"She got spooked by another horse and ditched me," she told BV Buzz. "I tore absolutely everything in my knee. My surgeon said 'impressive!' I am on crutches now and doing physical therapy. I'll have surgery in two weeks when the swelling goes down."
