Whether or not you have surgery, you can help reduce pain and swelling with rest, ice,compression, and elevation. Rest with your knee elevated above heart level. Put ice on your knee  3 to 5  times a day for  10 to 15 minutes at a time. Keep a thin cloth between the ice and your skin. A compressive wrap may also help reduce swelling. Take any medicines that are prescribed and follow any other instructions you’re given.

Crutches can help you get around during your recovery. They reduce stress on your knee. Follow your healthcare provider’s advice about the use of crutches and  how much weight to put on your injured leg. Use crutches or a brace for as long as advised.

For severe ACL injuries, you may need a procedure called ACL reconstruction. This is surgery that uses a graft (new tissue) to replace a torn ligament. If surgery is needed, your healthcare provider can give you more information about it.

Whether or not you have surgery, rehabilitation exercises are important. Exercise is needed to strengthen the muscles that support your knee. It will also help you regain flexibility, reduce pain, and prevent other knee problems in the future. Your healthcare provider can show you the best exercises for your knee. He or she will also tell you how long and how often to exercise.
