Partial knee replacement surgery is one of the least invasive options for knee replacement, and that also means it has one of the shortest recovery periods. Even if you don't choose to undergo the procedure as an outpatient, which would get you back home the very same day, most patients stay in the hospital no longer than overnight.
You can begin undergoing physical therapy immediately; in fact, it's recommended in order to assure you regain the maximum range of motion and muscle strength. Not one to stay in one place for long? No problem. After 4 to 6 weeks of working with your physical therapist, you'll be ready to take on the day once more.
