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 affect many of the ligaments in your knee by tearing the fibers of the tissues, which usually causes pain, swelling, and bruising.

If you have been diagnosed with a knee sprain, you can follow a few simple steps to recover as soon as possible.
