After your joint replacement surgery, you might go home on the same day or stay in the hospital for up to four days. Some people go to a rehabilitation center for a short time. Wherever you are, don't expect to lie in bed for long. A physical therapist will meet with you on the same day as your surgery, or on the next day, to get you up and moving. The therapist will teach you how to walk with the aid of a walker, cane or crutches. You will also learn how to go up and down stairs.
