ACL Injuries

ACL Tear & Injury

The Anterior Cruciate Ligament (ACL) is one of the key ligaments that stabilize the knee joint. Due to its central role in facilitating movement and balance, it is also prone to injury, especially among athletes. An ACL knee injury can range from mild sprains to severe tears, each with its own set symptoms, treatment and recovery.

What are Some Common ACL Injuries?

Mild ACL Sprain

Mild ACL Sprain

A mild sprain occurs when the fibres of the ACL has been overstretched, but not yet torn. Symptoms of a mild ACL sprain include tenderness, localised swelling, and discomfort when moving the knee. A mild ACL sprain can normally be treated without surgery through getting sufficient rest, walking aids like crutches, anti-inflammatory medications and icing.

Partial ACL Tear

Partial ACL Tear

A partial ACL tear occurs when the fibres of the ACL have been partly torn. Symptoms of a partial ACL tear include pain, swelling, and possible instability in the knee. In such cases, one may feel as though their knee is going to give out during activity. Not all partial ACL tears require surgery to treat; and this will be determined by the doctor’s assessment of the patient’s age, severity of symptoms, and goals.

Complete ACL Tear

Complete ACL Tear

A complete ACL tear occurs when the fibres of the ACL have been completely torn; also known as an ACL rupture. This is the most common type of ACL injury. When this occurs, one will experience immediate and significant pain and swelling; along with stiffness and instability of the knee. Complete ACL tears normally require surgery to treat.

ACL Avulsion Fracture

ACL Avulsion Fracture

An avulsion fracture of the ACL occurs when the ACL tears so severely that a piece of bone from where the ligament attaches to the leg, is broken off. This is usually caused by direct trauma during sports or a forceful hyperextension of the knee. There is usually immediate and severe pain at the time of injury, followed by rapid swelling and limited range of motion.

ACL Impingement

ACL Impingement

In an ACL impingement, the ligament finds itself trapped, pinched between other bony and soft tissue structures of the knee. This can result in chronic pain, limited mobility, as well as a grinding or crunching sensation when moving the knee.

ACL injuries must be evaluated in order to prevent the injury and symptoms from worsening.
