Skip Navigation

Your Recovery

Hip replacement surgery replaces the worn parts of your hip joint.

You will need to be careful to protect your new joint after hip replacement surgery. Along with doing your physical therapy exercises, there are many things you can do to help your hip heal. Your recovery may be faster if you follow these precautions.

Try to keep your hip within the safe positions while it heals. Some leg and foot movements may increase the risk of dislocating your hip. Try to avoid those positions.

  1. Don't lean forward while you sit down or stand up, and don't bend past 90 degrees (like the angle in a letter "L"). This means you can't try to pick up something off the floor or bend down to tie your shoes.
  2. Don't lift your knee higher than your hip.
  3. Don't sit on low chairs, beds, or toilets. You may want to use a raised toilet seat for a while. Sit in chairs with arms.

  1. Imagine there's a line running down the middle of your body. Keep your legs from crossing over it.
  2. When you get into a car, back up to the seat of the car, and then sit and slide across the seat toward the middle of the car with your knees about 12 inches apart. A plastic bag on the seat can help you slide in and out of the car.
  1. Don't cross your legs when you sit.
  2. Don't cross your ankles while lying down.
  3. It may help to keep a pillow between your knees when you're in bed.

Other tips

  • Go slowly when you climb stairs. Make sure the lights are on. Have someone watch you, if you can. When you climb stairs:
    • Step up first with your unaffected leg. Then bring the affected leg up to the same step. Bring your crutches or cane up.
    • To go down stairs, reverse the order. First, put your crutches or cane on the lower step. Then bring the affected leg down to that step. Finally, step down with the unaffected leg.
  • You can ride in a car, but stop at least once every hour to get out and walk around.
  • You may want to sleep on your back. Don't reach down too far to pull up blankets when you lie in bed.
  • If your doctor recommends exercises, do them as directed. You can cut back on your exercises if your muscles start to ache, but don't stop doing them.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
