Medically reviewed by Drugs.com. Last updated on May 4, 2025.
Arthroscopic anterior cruciate ligament (ACL) reconstruction is surgery to replace your torn ACL. The ACL is a ligament in your knee that connects the tibia (shin bone) to the femur (thigh bone). Ligaments are strong tissues that connect bones.
DISCHARGE INSTRUCTIONS:
Call your local emergency number (911 in the US) if:
- You have sudden shortness of breath or chest pain.
Seek care immediately if:
- Blood soaks through your bandage.
- Your stitches come apart.
- You fall on your knee.
- You have pain in your lower leg and swelling or a red area near the pain.
- Your leg or toes feel numb, tingly, cool to the touch, or look blue or pale.
Call your doctor or surgeon if:
- You have a fever.
- You have severe pain in your knee or trouble moving around, even after you take your pain medicines.
- Your wound is swollen, red, or draining pus.
- Your skin is itchy, swollen, or has a rash.
- You have questions or concerns about your condition or care.
Medicines:
- 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.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider 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.
Elevate your knee:
Keep your knee raised above the level of your heart as often as you can. This will help decrease or limit swelling. Elevate your knee by resting it on pillows.

Apply ice to the surgery area:
Ice helps decrease swelling and pain. Ice may also help prevent tissue damage. Use an ice pack, or put crushed ice in a plastic bag. Cover the bag with a towel and place it on the area for 15 to 20 minutes every hour. Use the ice for as long as directed.
Rest your knee as directed:
Your healthcare provider will tell you when you can return to your normal activities.
Apply compression as directed:
Compression provides support and helps decrease swelling and movement so your joint can heal. Do not wrap the bandage tightly. It should be snug, but you should be able to slip a finger between the bandage and your skin.

Go to physical therapy as directed:
Physical therapy is used to help you improve movement and strength, and to decrease pain.
A continuous passive motion (CPM) machine
is a device that slowly and gently moves your joint while you are in bed. The machine can increase your range of motion, strengthen your muscles, and decrease pain. Your healthcare provider may tell you use a CPM machine with other treatments, such as physical therapy.
Use support devices as directed:
- A knee brace may be used to limit your movement and protect your knee. Your healthcare provider will tell you when you can unlock the brace. Keep it locked at all other times. Ask your healthcare provider for more information about your knee brace.
- Crutches may help decrease your pain as you move around. Crutches help decrease strain on your knee. Use crutches as directed.
Wound care:
- Keep your bandage and stitches clean and dry. Do not remove the bandage over the surgery area or get it wet unless your healthcare provider says it is okay. Ask when you can bathe. Do not trim or shorten the ends of your stitches. If the stitches rub against your clothing, you can put a soft gauze bandage between the stitches and your clothes. Strips of medical tape that were placed over the incision will start to peel off on their own. If they have not fallen off within 14 days, you can carefully peel them off.
- Wash your hands. Always wash your hands before and after you care for your wound to prevent infection.
- Change your bandage and clean the surgery area as directed. Ask for help if you cannot reach the area. Do not put powders or lotions on the area. Check the area every day for signs of infection such as redness, swelling, or pus.
Follow up with your doctor or surgeon as directed:
You may need to return to have your stitches removed. Write down your questions so you remember to ask them during your visits.
