Anterior Cruciate Ligament Injury (ACL)
A knee injury that results from a tear or severe break in the Anterior Cruciate Ligament. This ligament runs diagonally across the middle of the knee joint and connects the lower leg bone to the thigh bone.
Condition typically occurs during non-contact injuries, such as landing on a straight leg (usually during sports or other physical activities), making a sudden stop and other motions that exert stress on the area.
Symptoms of a torn ACL include a “popping” sound when the tear occurs, inability to walk on the affected leg and moderate pain and swelling of the knee joint.
An ACL injury cannot heal on its own, requiring the individual to employ physical training and stretching techniques to build up the other surrounding knee muscles. This helps to aid in regaining motion and strength to the affected area.
Some ACL injuries can be surgically repaired, where the ACL is replaced with parts of the individual’s hamstring or patellar tendon
