Question: how long do you have to stay in hospital after knee replacement?
Answer: Typically, knee replacement patients are able to leave the hospital within 1 to 5 days (often 2 or 3), and they can take care of themselves and resume most activities 6 weeks after surgery. The majority of patients are 90% recovered after 3 months, though it can take 6 months or longer before they are 100% recovered.
