When you leave the hospital you will be given specific wound-care instructions and discharge instructions for activity level, medication, and any further restrictions necessary. Your healthcare provider will let you know of any symptoms that require immediate medical attention.
Most people require a few months of physical therapy to work on knee motion, strength and walking. Therefore, if needed, supervised exercises will continue for 4-6 weeks. This may require attending intensive physical therapy sessions at a rehabilitation hospital or you may be able to arrange for a therapist to visit your home.
After this time period, your doctor and therapist will evaluate your progress and determine whether you need continued physical therapy, or if you can continue these exercises on your own to maintain overall conditioning.
