After knee replacement surgery, patients usually stay in the hospital for 1 to 3 days, depending on their overall health and how well they progress post-operatively. During this time, our medical team will help you manage pain, monitor vital signs, and begin physical therapy to encourage movement in the new knee joint. Patients are typically encouraged to start walking with the aid of a walker or crutches within 24 hours of surgery. The hospital stay also includes education on caring for the surgical site and managing pain at home.
