Total knee replacement (TKR) surgery is a common joint replacement procedure that helps relieve knee joint pain and restore impaired joint function. The procedure results in a better quality of life for most patients, but it does require a focused recovery period to increase the chances for quick healing and success.

First Days

Most TKR patients stay in the hospital for one to two days, though some are able to return home the day of surgery if they have sufficient support and don't experience any complications during or after surgery. Your knee may have a drainage tube to help prevent fluid from gathering around your knee, and you may have an IV for fluids and pain medication.

Medical staff will help you get out of bed and move around the day of your surgery unless your surgeon directs otherwise. You won't be able to stand or walk for longer than a few minutes during the first week of recovery.

First Weeks

You'll likely need to use a walker or another assistive device to get around for the first two to three weeks after knee replacement surgery. Your surgeon will prescribe pain medication and direct you on when and how to take it once you're discharged from the hospital. 

Most total knee patients begin physical therapy about a week after surgery. Your physical therapist will assess your condition and help you strengthen your new knee joint. Perform your home exercises as your therapist advises you, to improve your knee's range of motion and reduce scar tissue buildup.

Your swelling should go down substantially during the first few weeks of recovery, which will make it easier to bend and straighten your knee and make it easier for you to stand or walk for more than a few minutes at a time.

One Month and Beyond

Your surgeon will likely clear you to drive when you have four to six weeks of recovery time. Most people are able to return to basic household duties, such as cooking and light cleaning, about a month after surgery.

Many TKR patients who work sedentary or desk jobs are able to return to work between four and six weeks post-surgery. If your job requires you to lifting, walking, or prolonged standing, you might be out of work for three months or longer.

You'll be able to increase your physical activity as your knee gets stronger and you develop a wider range of motion, but high impact activities, such as basketball, football, running, and aerobics, should still be avoided until cleared by your surgeon.

Discuss your total knee replacement surgery and recovery in detail with your surgeon and follow all of their directions to give yourself the best recovery possible.
