Your Care Instructions

The kneecap (patella) is a bone that protects the front of your knee joint. It takes the brunt of any blows to your knee, such as a fall onto your knee or your knee hitting the dashboard. Symptoms of a broken kneecap (fracture) are swelling and pain, especially when moving the knee back and forth.

You may not need surgery if the fracture has not moved your kneecap out of position. But sometimes surgery is needed to move the pieces of the kneecap back where they belong and to repair damage. Whether or not you have surgery, you probably will wear a cast or immobilizer on your leg for several weeks while the kneecap heals. Wear and take care of the cast or immobilizer exactly as your doctor advises. You may need to ask for help with daily tasks.

You heal best when you take good care of yourself. Eat a variety of healthy foods, and don't smoke.

How can you care for yourself at home?

• Follow your doctor's instructions for taking care of your cast or immobilizer, which is a protective brace that keeps your knee from moving. Do not remove it until your doctor says you can.
• Prop up the sore leg on a pillow when you ice it or anytime you sit or lie down during the next 3 days. Try to keep it above the level of your heart. This will help reduce swelling.
• Put ice or a cold pack on your knee for 10 to 20 minutes at a time. Try to do this every 1 to 2 hours for the next 3 days (when you are awake) or until the swelling goes down. Put a thin cloth between the ice and your skin. Be careful not to get the cast or immobilizer wet.
• Do not use oils or lotions near your cast. If the skin becomes red or sore around the edge of the cast, you may pad the edges with a soft material, such as moleskin, or use tape to cover the edges.
• Be safe with medicines. Read and follow all instructions on the label.
  • If the doctor gave you a prescription medicine for pain, take it as prescribed.
  • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
