The Knee also known as the patella has four main ligaments. These Knee ligaments will be explained in further detail below. Ligaments are tough bands of tissue that connect the bones in your body. There are four ligaments in the knee that are prone to injury:
The four main ligaments in the knee connect the femur (thighbone) to the tibia (shin bone), and include the following:
· Anterior cruciate ligament (ACL) - The ligament, located in the center of the knee, that controls rotation and forward movement of the tibia.
Posterior cruciate ligament (PCL) - The ligament, located in the center of the knee, that controls backward movement of the tibia (shin bone). (It’s rarely injured except in car accidents).
· Medial collateral ligament (MCL) - The ligament that gives stability to the inner knee.
· Lateral collateral ligament (LCL) - The ligament that gives stability to the outer knee.
Ligament injuries in the knee -- such as an anterior cruciate ligament (ACL) -- can put you on the sidelines -- fast. They are very painful and may limit what you can do.
However, more often than not, a comeback may still be possible. Treatment is more successful than it once was.
What Does a Knee Ligament Injury Feel Like?
You may have:
Your doctor will give you a physical exam. If your knee is very tense and swollen with blood, your doctor may use a needle to drain it. This is called a needle aspiration. You may need X-rays to make sure you don’t have a broken bone, as well as an MRI to check on any ligament injuries.
A mild to moderate knee ligament injury may heal on its own, in time. To speed the healing, you can: A more severe injury such as a full tear will require surgical repair.
Rest the knee. Avoid putting much weight on your knee if it's painful to do so. You may need to use crutches for a time.
