Foot drop is a medical sign for the nerve not working, the muscle not working or an anatomical problem. I would guess your’s is due to the nerve. Peripheral nerves do regrow so since you’ve had surgery to relieve the pressure on your sacral nerve, give it time and attend the physical therapy and you’ll see improvements.
