FAQs About ACL Surgery

What is an ACL injury?

The ACL (anterior cruciate ligament) is one of the main ligaments that stabilizes the knee. An ACL injury usually occurs when the knee twists suddenly, often during sports or quick directional changes. A torn ACL can cause pain, swelling, and a feeling that the knee may “give out”.

Do ACL tears heal on their own?

NO. Unlike some other ligaments, the ACL does not heal on its own once torn. For patients who want to return to an active lifestyle, ACL reconstruction surgery is often recommended to restore knee stability.

What happens during ACL reconstruction surgery?

During ACL surgery, the torn ligament is replaced with a graft that acts as a new ACL. The surgeon carefully positions and secures the graft inside the knee to restore normal movement and stability.

What is an ACL graft?

An ACL graft is tissue used to replace the torn ligament. It may come from the patient’s own body (autograft) or from a donor (allograft). The graft is prepared and shaped during surgery to fit the knee precisely.

Why is graft placement so important?

Proper graft placement is critical for long term success. Correct positioning and tension help restore natural knee motion, improve stability, and reduce the risk of re-injury,

How long does ACL recovery take?

Recovery varies by patient, but most people return to daily activities within a few months. Returning to sports typically takes 6-12 months, depending on strength, rehabilitation progress, and surgeon guidance.

Will I need PT (physical therapy) after ACL surgery?

YES. Physical therapy is a key part of recovery. Therapy helps restore strength, flexibility, and confidence in the knee. A well performed reconstruction provides a strong foundation for successful rehab.

Can ACL surgery prevent future knee problems?

While no surgery guarantees zero risk, ACL reconstruction helps restore stability and can reduce the risk of further injury and long term knee damage when combined with proper rehabilitation.
