Sprains

Sprains are some of the most common knee injuries. A sprain is when a ligament is over-streched, and/or torn. When the injury happens there is a popping sound from the knee. A sprained ligament causes pain and the knee can no longer support weight, it feels lose and unstable. Fluid building up behind the knee cap is also common, this causes swelling. Sprains usually affect the MCL and the ACL (see diagram). Meniscal tears are common with severe sprains and tears. The minisci is a tough pad of cartilage. when torn there is usually tenderness and tightness added to the symptoms of a sprain. Strains are very much like sprains, but include bruising. media type="youtube" key="-RIfDV2_z7E" height="344" width="425" home
