The doctor will make a cut in the skin. The damaged cartilage and bone will be removed. The remaining bone will be prepared to receive the new plastic and metal joint. The doctor will then place the artificial joint in the proper position. It will be cemented within the bone. The doctor will close the incision with staples. A drain will be left in to allow extra fluid to flow out.

At the Hospital
While you are recovering at the hospital, you may need to:
Use a continuous passive motion machine, which is designed to:
Slowly move your knee
Move your foot and ankle to increase blood flow back to your heart.
Wear support stockings. These may help prevent blood clots from forming in your legs.

Slowly progress to walking and then to climbing stairs. Avoid jogging and other high-impact sports.
Get the staples removed in a few weeks.

Talk to your doctor before taking over-the-counter medicines.
Take antibiotics before surgery or dental procedures. Antibiotics will decrease the risk of bacteria entering the bloodstream and traveling to the artificial knee.
