First Aid for Knee Sprains
Ensure that you apply ice for 20 minutes at a time, which can reduce the inflammation because it constricts the blood vessels around the sprain area. This will reduce the inflammation and allow the joint to heal faster. Make sure to use a plastic bag or a towel to put the crushed ice as putting ice directly on the skin can cause further injury.
You may also use an elastic bandage available in a pharmacy. In this way, a sprained knee can be given extra support, both to make yourself comfortable and to improve healing. You can also lie down flat and raise your knees above your heart to decrease the swelling. Most importantly, though, rest your knees, avoid putting weight on them for a while. By avoiding stressing the knee, it will allow damaged ligaments to heal faster and stronger. For more details, take a look at the post on the RICE method.

Special exercises are often prescribed for treating knee sprains. Some sprains also benefit from physical therapy.
By and large, creams and gels with pain relieving drugs can be applied in case of severe and prolonged pain. Anti inflammatory medications are also used for treating sprains. NSAIDs (Non-Steroidal Anti Inflammatory Drugs) are especially common – both over the counter and by prescription. A very severe sprain – such as a torn ACL – may lead to surgical treatment.
