An ACL tear is a common knee injury that involves damage to the anterior cruciate ligament (ACL), one of the major ligaments in the knee joint. The ACL helps stabilize the knee and prevent excessive forward movement of the shin bone (tibia) relative to the thigh bone (femur). ACL tears can occur due to sudden twisting, pivoting, or forceful impact to the knee, often during sports activities or accidents.
Did you know?
Despite its importance in stabilizing the knee joint, the ACL is only about the size of a pencil and is not able to regenerate or heal on its own once torn. This is why ACL tears often require surgical intervention to restore stability and function to the knee.
Frequently Asked Questions
What causes an ACL tear?
ACL tears can occur due to sudden twisting, pivoting, or forceful impact to the knee, often during sports activities such as soccer, basketball, football, skiing, or gymnastics. Factors such as poor conditioning, improper technique, and inadequate warm-up can increase the risk of injury.
How is an ACL tear diagnosed?
Diagnosis of an ACL tear typically involves a physical examination, medical history review, imaging tests such as MRI or X-rays, and possibly specialized tests such as stress tests or arthroscopy to evaluate the extent and location of the tear.
What are the treatment options for an ACL tear?
Treatment options for an ACL tear depend on the severity of the injury, as well as the patient’s age, activity level, and overall health. Conservative treatments may include rest, ice, compression, elevation (RICE), physical therapy, and bracing. In cases of complete tears or persistent symptoms, surgical intervention such as ACL reconstruction may be recommended to restore stability and function to the knee joint.
