One thing fans noticed on Chrisley Knows Best was the boot on Todd's leg. It wasn't an actual cast, but it did mean he had to ride around on a motorized scooter, much to his own amusement. He originally broke his leg, which led to a standard cast and crutches.
But the break was so serious he had to undergo surgery and get a steel plate and screws inserted into his leg. As a result, Todd had to endure physical therapy to get his leg functioning properly again.
