A to Z: Sprain, Knee

A sprain is the stretch or partial tear of ligaments (which connect two bones). A knee sprain happens when a ligament is stretched or torn because the knee gets twisted, bent, or hit.

More to Know

The knee joint is made up of bones, ligaments, and tendons (bands that attach muscle to bone). It can happen when a person falls or during sports, especially if someone takes on too much physical activity too quickly.

Keep in Mind

Most sprains will heal in 8 weeks with rest and an appropriate exercise program. A sprained knee can be uncomfortable but resting the knee and doing the recommended exercises can help someone slowly return to normal activities.
