One of the four major knee ligaments, your ACL (anterior cruciate ligament) is important for knee stability. It is located under the kneecap and is responsible for preventing excessive motion in the knee joint.
How Does an ACL Injury Occur?
We typically think of an ACL tear as a sports injury, but they can also result from falls, work injuries, rough play, and car accidents. Most ACL tears happen when you are landing from a jump or pivoting.
Symptoms of an ACL Tear
When you tear your ACL, you may feel or hear a pop in your knee joint. This is followed by swelling and pain. You will also feel your knee give out from under you.
Diagnosing an ACL Tear
When your doctor suggests that you may have an ACL tear, they may order an MRI. An MRI uses magnetic fields to create images of the structures within your body, which can show your doctor the extent of the damage. Once your doctor can see the severity of the injury, they can prescribe a treatment plan for you.
