The Anterior Cruciate Ligament (ACL) is one of the most commonly injured ligaments in the knee. Ligaments are the strong, non-elastic fibers that connect our bones together. The ACL crosses inside of the knee, connecting the thighbone to the leg and provides stability to the knee joint.
ACL tears are most common in very active people or athletes. The ACL can tear when people abruptly slow down from running, land from a jump, or change directions rapidly. These actions are frequently performed during sports, such as football, basketball, and soccer. Although athletes are especially at risk for ACL tears, they may also occur in active workers and the general population.
When the ACL is injured, it is common to see other surrounding knee structures damaged as well. Some ACL injuries may treated with non-surgical methods, but several factors, such as the severity of the injury and a person’s activity level, are reviewed when determing if surgery is necessary.
When you injure your anterior cruciate ligament, you might hear a popping sound and may feel your knee give out from under you. Other typical symptoms include:
If you suspect you have torn your ACL, you should see your Celebration Orthopaedics orthopaedic surgeon right away. He will evaluate your knee by gathering your medical history, performing a physical examination, and viewing medical images. He will ask you about your symptoms and what happened if you were injured.
The anterior cruciate ligament can be injured in several ways:
It is common for additional injuries to result when an ACL tear occurs. Surrounding structures, such as the meniscus, cartilage, and ligaments can be injured as well. Some people may also experience bruised or broken bones.
Research has shown that female athletes have a higher incidence of ACL injury than male athletes in certain sports. It is suspected that the greater angles in the female hip and leg alignment may make the knee more vulnerable to force. Additionally, female hormones can relax ligaments and make them less stable, making some women more susceptible to knee injury.
