Knee Replacement Surgery Discharge Information

What is knee replacement surgery?

The knee is a large joint that joins your thigh bone (femur) with your shin bone (tibia). The kneecap (patella) and the smaller bone in your lower leg (fibula) are also part of this joint. Tendons connect your leg muscles to the knee bones so that the joint can move. Ligaments connect the bones of the joint to one another and give the knee stability. The cartilage and fluid-filled sacs in the joint help the knee move smoothly.

The most common cause for knee replacement is severe pain, often from arthritis. The surgery is done to remove damaged bone and cartilage from the knee joint and replace it with man-made pieces. There are 3 knee joint surfaces that may be affected: the lower end of the thigh bone, the upper end of the shin bone, and the back of your kneecap.

How can I take care of myself when I go home?

How long it takes to get better depends on how well you recover, your overall health, and any complications you may have.

Management

  • Your provider will give you a list of your medicines when you leave the hospital.
    • Know your medicines. Know what they look like, how much you should take each time, how often you should take them, and why you take each one.
    • Take your medicines exactly as your provider tells you to.
    • Carry a list of your medicines in your wallet or purse. Include any nonprescription medicines and supplements on the list.
  • Your provider may prescribe medicine to:
    • Treat pain
    • Treat or prevent an infection
    • Prevent side effects, such as nausea or constipation, from other treatments
    • Help prevent blood clots
    • Help build bone and prevent bone loss
  • You may need to continue a rehabilitation program after you leave the hospital to help you recover from knee replacement surgery. Most rehabilitation programs include:
    • Physical therapy to help you regain muscle strength and teach you ways to move safely
    • Occupational therapy to help you relearn safe ways to do the tasks that you did before your knee replacement surgery
  • To care for your incision:
