WHAT YOU NEED TO KNOW:
What do I need to know about knee pain?
Knee pain may start suddenly, or it may be a long-term problem. You may have pain on the side, front, or back of your knee. You may have knee stiffness and swelling. You may hear popping sounds or feel like your knee is giving way or locking up as you walk. You may feel pain when you sit, stand, walk, or climb up and down stairs.
What increases my risk for knee pain?
- A strain or tear in ligaments or tendons
- A leg fracture or knee dislocation
- Overuse of your knee
- Osteoarthritis, rheumatoid arthritis, or gout
- An infection, tumor, or cyst in your knee
- Shoes that are not supportive, or training on a hard surface
- Sports that involve jumping or pivoting on your knee
How is the cause of knee pain diagnosed?
Your healthcare provider will examine your knee and ask about your symptoms. Tell your provider when the pain started and what you were doing at the time. Describe the pain, such as sharp, throbbing, or achy. Tell your provider about any knee injury or surgery you had. You may need any of the following:
- MRI, CT, or ultrasound pictures may show an injury, fracture, or tumor.
- Blood tests may be used to check the level of inflammation in your blood. The tests may also show signs of infection.
- Arthroscopy is a procedure to look inside your knee joint with an arthroscope. An arthroscope is a flexible tube with a light and camera on the end. A knee arthroscopy is usually done to check for disease or damage inside your knee. These problems may be fixed during the procedure.
How is knee pain treated?
Treatment will depend on the cause of your pain. You may need any of the following:
- NSAIDs help decrease swelling and pain or 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.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- 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.
- Steroid injections may be given into your knee. Steroids reduce inflammation and pain.
- Surgery may be used for some injuries, such as to repair a torn ACL.
What can I do to manage my symptoms?
- Rest your knee so it can heal. Limit activities that increase your pain. Do low-impact exercises, such as walking or swimming.
- Apply ice to help reduce swelling and pain. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel before you apply it to your knee. Apply ice for 15 to 20 minutes every hour, or as directed.
- Apply compression to help reduce swelling. Use a brace or bandage only as directed.
- Elevate your knee to help decrease pain and swelling. Elevate your knee while you are sitting or lying down. Prop your leg on pillows to keep your knee above the level of your heart.
- Prevent your knee from moving as directed. Your healthcare provider may put on a cast or splint. You may need to wear a leg brace to stabilize your knee. A leg brace can be adjusted to increase your range of motion as your knee heals.
What can I do to prevent knee pain?
- Maintain a healthy weight. Extra weight increases your risk for knee pain. Ask your healthcare provider how much you should weigh. He or she can help you create a safe weight loss plan if you need to lose weight.
- Exercise or train properly. Use the correct equipment for sports. Wear shoes that provide good support. Check your posture often as you exercise, play sports, or train for an event. This can help prevent stress and strain on your knees. Rest between sessions so you do not overwork your knees.
When should I seek immediate care?
- Your pain is worse, even after treatment.
- You cannot bend or straighten your leg completely.
- The swelling around your knee does not go down even with treatment.
- Your knee is painful and hot to the touch.
When should I contact my healthcare provider?
- You have questions or concerns about your condition or care.
