What should I do if my knee swells after knee replacement surgery?

Travis M. Hendry, MD
Orthopedic Surgery
Some swelling after knee replacement surgery is normal. Many patients experience enough swelling to make their knee feel stiff for several months. It should decrease every week, however.
  • Elevating your leg can usually reduce swelling. Especially during the first few weeks, prop your leg up whenever you're sitting. Apply an ice pack.
  • If swelling continues to increase and does not improve when you elevate your leg, you could have a blood clot, bleeding, or an infection. If swelling and pain get worse, contact your surgeon. You may be asked to go to the hospital for tests.
