Knee Arthroscopy


A knee 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.


Call 911 for any of the following:

  • You feel lightheaded, short of breath, and have chest pain.
  • You cough up blood.
  • You have trouble breathing.

Seek care immediately if:

  • Blood soaks through your bandage.
  • Your stitches come apart.
  • Your leg feels numb or cold and looks pale.
  • Your leg is larger than normal, red and painful.
  • You cannot move your leg or foot.

Contact your healthcare provider if:

  • You have a fever or chills.
  • Your wound is red, swollen, or draining pus.
  • You have nausea or are vomiting.
  • You have severe pain in your knee even after you take pain medicine.
  • Your skin is itchy, swollen, or you have a rash.
  • 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.
  • 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. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him 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.

Care for your wound as directed:

Ask your healthcare provider when your wound can get wet. Carefully wash around the wound with soap and water. Allow soap and water to gently run over your incision. Do not scrub the incision. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty. Check your wound 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.
  • Elevate your knee above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your leg on pillows or blankets to keep it elevated comfortably. Do not put pillows directly behind your knee.
  • Wear your knee brace and pressure stockings as directed. Your brace will prevent your knee from moving and may help it heal. Pressure stockings put pressure on your legs to help blood flow and prevent clots.
  • Keep weight off of your knee as directed. Use crutches or other assistive devices to keep pressure off of your knee. Ask your healthcare provider how long you need to keep weight off of your knee.
  • Do not drive for 1 to 3 weeks or as directed. Your ability to drive may depend on the knee that was operated on, the type of car you drive, your pain level, and when you stop taking pain medicine. Do not drive while you are taking prescription pain medicine.
  • Go to physical therapy as directed. A physical therapist teaches you exercises to help improve movement and strength, and to decrease pain. Ask your healthcare provider when you should start physical therapy.

Follow up with your healthcare provider as directed:
