The Anterior Cruciate Ligament (ACL) is one of the most important parts of the knee as it is one of the four main ligaments of the joint. As one of the most common sports injuries, the Anterior Cruciate Ligament (ACL) can be torn or injured, leaving patients with an unstable or painful knee. While some non-invasive techniques that can help patients regain full use of their knee do exist, severe injuries may require surgical intervention. By reconstructing the Anterior Cruciate Ligament (ACL), the surgeon removes what remains of the torn ligament and replaces it with a healthy tendon from another part of the patient’s body.
