A tear of the anterior cruciate ligament is a common knee injury that occurs with damage to other parts of the knee. Injuries to the ACL are classified as Grades 1 to 3 based on severity. A Grade 1 sprain is a mild tear, while a Grade 2 tear results in the ligament being loose and tearing. It is best to see a doctor immediately if you suspect that your knee is injured.
ACL injuries can occur in any activity involving the knee, including sports and activities such as jogging and running. Even simple falls can cause an ACL tear. Trauma victims and athletes often suffer ACL tears. Although most people would assume that these injuries are caused by contact, they are most often the result of non-contact deceleration. In some cases, the injury may be due to hyperextension or internal rotation, or even a combination of these two.
The anterior cruciate ligament is a tough, flexible band of tissue that holds the bones in the knee joint together. ACL injuries can occur during sudden turns or movements. A complete tear requires surgery to repair the knee. Fortunately, the condition is treatable. There are many ways to treat an ACL injury.
