ACL-The ACL (Anterior Cruciate Ligament) is one of the four ligaments connecting the bones of the knee. The ACL provides stability to the knee, and minimizes the stress to the knee joint. A tear of this ligament often results from overstretching and twisting type activities.

MCL- The MCL (Medial Collateral Ligament) is also one of the four major ligaments that connect the bones in the knee. The MCL goes from the end of the thigh bone (femur), to the top of the shin bone, (tibia). This ligament is often injured when there is some sort of blunt force to the outside of the knee and during cutting type sports/activities.

IT Band-The IT band goes from the hip, to the outside of the shin just under the knee. Illiotibial Band Syndrome (IT band syndrome) occurs when the IT Band gets tight, or inflamed causing friction and irratation. It is usually seen in individuals who run, bike, hike, etc.

Strain/Sprain- Knee strains occur when ligaments and tendons in the knee become stretched, or torn. These injuries are generally caused by overuse, or an extreme blow to the knee.
