For acute injuries, you may have to stay off your feet as much as possible or even use crutches for a short time. Ice. Put ice on your knee for 15 to 20 minutes a few times each day. Use ice cubes or a bag of frozen vegetables wrapped in a towel. Compression. Wrap an elastic bandage around your knee to help control swelling. Make the bandage fit snugly around your knee, but not tight enough to cause pain or leg swelling.
A knee sprain is an injury to the ligaments in the knee, which are the tough, elastic-like bands in the knee that connect your bones together and hold your joints in place. A sprain can effect many of the ligaments in your knee by tearing the fibers of the tissues, which usually causes pain, swelling, and bruising.
