WHAT YOU NEED TO KNOW:
Knee replacement is surgery to replace all or part of your knee joint. It is also called knee arthroplasty. It is normal to have some stiffness and pain after surgery. Your pain and stiffness should get better with exercise.
Call 911 for any of the following:
- You feel lightheaded, short of breath, and have chest pain.
- You cough up blood.
Seek care immediately if:
- Your leg feels warm, tender, and painful. It may look swollen and red.
- You cannot walk or move your knee.
- Blood soaks through your bandage.
- Your incision comes apart.
- Your incision is red, swollen, or draining pus.
Contact your healthcare provider if:
- You have a fever or chills.
- You have trouble moving or bending your knee.
- You have new knee pain or pain that does not get better with medicine.
- You have questions or concerns about your condition or care.
You may need any of the following:
- Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
- Blood thinners help prevent blood clots. Examples of blood thinners include heparin and warfarin. Clots can cause strokes, heart attacks, and death. The following are general safety guidelines to follow while you are taking a blood thinner:
- Watch for bleeding and bruising while you take blood thinners. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
- Tell your dentist and other healthcare providers that you take anticoagulants. Wear a bracelet or necklace that says you take this medicine.
- Do not start or stop any medicines unless your healthcare provider tells you to. Many medicines cannot be used with blood thinners.
- Tell your healthcare provider right away if you forget to take the medicine, or if you take too much.
- Warfarin is a blood thinner that you may need to take. The following are things you should be aware of if you take warfarin.
- Foods and medicines can affect the amount of warfarin in your blood. Do not make major changes to your diet while you take warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables and certain other foods. Ask for more information about what to eat when you are taking warfarin.
- You will need to see your healthcare provider for follow-up visits when you are on warfarin. You will need regular blood tests. These tests are used to decide how much medicine you need.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
- A physical therapist will teach you exercises to strengthen the muscles around your knee. The exercises will help decrease pain and swelling. Do your exercises as many times as directed. The therapist will show you how to move without damaging your knee.
- An occupational therapist will show you how to do daily activities safely. He or she may recommend assistive devices to help you dress, bathe, and pick up things. The assistive devices will help keep you from twisting and bending, which can damage your knee.
- Use assistive devices as directed. Your thigh muscles will be weak after surgery. Assistive devices will help you not fall.
- Go up the stairs by placing your non-operated leg on the step first. Then bring your operated leg to the same step. Repeat.
- Go down stairs by placing your operated leg down on the step first. Then bring your non-operated leg to the same step. Repeat.
- Do not cross your legs for 6 weeks or as directed. Your risk for blood clots is greater when you cross your legs. You can also move your implant out of place.
- Do light housekeeping duties. Ask your healthcare provider which duties would be okay for you to do. He or she may tell you it is okay to dust or do dishes. Avoid vacuuming, changing the bed, or any duty that has you reaching up, bending, or twisting.
- Do not drive for at least 6 weeks or until your healthcare provider says it is okay.
- Do not play contact sports, tennis, golf, or ski until your healthcare provider says it is okay. These activities can loosen your knee implant.
Care for your incision area as directed:
Do not get the area wet until your healthcare provider says it is okay. Carefully wash the area with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty. Do not put powders or lotions over the area. If you have strips of medical tape over the incision area, let them dry up and fall off on their own. If they do not fall off within 14 days, gently remove them. Check the area every day for signs of infection, such as swelling, redness, or pus.
- Apply ice on your knee for 15 to 20 minutes every hour or as directed. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel. Ice helps prevent tissue damage and decreases swelling and pain.
- Do not soak in a tub or pool until your incision area is healed or your healthcare provider says it is okay.
- Carry your ID card for your joint replacement at all times. All healthcare providers need to know about your joint replacement. You may need antibiotics before any procedure to prevent an infection of your new joint. The metal in your new joint may set off metal detectors. You will not be able to have an MRI because of the metal in your joint.
- Remove all loose carpets and cords. These can cause you to trip and fall.
- Use a shower bench or chair when you take a shower to limit the time you are standing.
- Use a toilet seat riser with arms if your toilet seat is low. A toilet seat riser will help prevent bending or twisting your knee.
- Know your limits. Start activities slowly and give yourself rest periods. Pain and swelling can increase when you do too much. Do not do an activity until your healthcare provider says you are ready.
