Anterior Cruciate Ligament (ACL) is one of four ligaments in the knee and is responsible for stability, forward movement of the lower leg, and preventing rotational stress. It connects the bottom of the femur (thighbone) to the top of the tibia (shinbone). Too much stress can cause an ACL to tear, making it the weakest of the four ligaments in the knee.

Professional and amateur athletes are most prone to ACL injuries due to repetitive stress on the knee. Sports that involve sudden stops and changes in direction are the most common to involve an ACL injury (basketball, soccer, tennis, and volleyball).

Symptoms of an ACL injury

• A loud “pop” or a “popping” sensation in the knee
• Severe pain and inability to continue an activity
• Swelling that begins within a few hours
• Loss of range of motion
• A feeling of instability or “giving way” with weight-bearing

What is the treatment?

Reconstructive surgery is typically performed to avoid collateral damage such as meniscus tears and degenerative joint disease in the future. Thi surgery also provides function and stability in the knee.

Orthopedic surgeons use either an allograph (from a cadaver) ligament or an autograph (the patient’s own tissue, usually from the knee cap tendon or the hamstring) for the repair.

Can ACL injuries be prevented?

Improving muscular reactions with jumping and balance drills can help lower the chances of an injury happening; however, it is difficult to prevent an ACL injury from occurring
