It depends on the severity of your injuries. Here are some of the alternatives you may be given by your doctor :
First Aid - If your damage is minimal, all you need to do is apply ice to your knee, elevate your leg, and take some time off your feet. Wrapping an ace bandage across your knee will help to minimize swelling. Crutches might assist in removing weight from your knee.
Medications - Anti-inflammatory medications can aid in the reduction of swelling and pain. Your doctor may advise you to take over-the-counter drugs or prescribe a stronger medication. Your doctor may inject steroid medication into your knee if you're in a lot of discomforts.
Brace for the knees - When running or participating in sports, some persons with a torn ACL can get away with wearing a brace on their knee. It provides further assistance.
Physical therapy - It is a type of treatment that involves the use of your knee back in functioning order, you may need to do this a few times a week. You'll undertake exercises to strengthen the muscles around your knee and help you restore a complete range of motion during your sessions. You may be sent home with some exercises to do on your own.
Surgery - If your ACL is badly torn, if your knee gives way when you walk, or if you're an athlete, your doctor may recommend this. The injured ACL will be removed and replaced with tissue to allow a new ligament to develop in its place. People who have had surgery can often return to sports within a year with the help of physical therapy.
