How long until my knee feels better after total knee replacement surgery?

It depends: Full recovery after knee replacement usually takes more than a year. Most patients reduce their use of pain medicines within two weeks of the replacement, by 6 weeks they are comfortable and usually by 3 months the knee is fading into the background, and life doesn't revolve around the new knee. Everyone is different and this is a general time line. If you are concerned tell your doctor.

6 - 12 weeks: The knee may feel somewhat better by six weeks and much better by twelve weeks.

3 months: It takes about 6 weeks to feel better than you did before surgery when walking and 3 months to return to all normal activities. I tell patients that it will be a year before you reach maximal improvement.
