A completely torn ACL is typically characterized by an immediate, audible "pop," severe pain, rapid swelling within 6 hours, and immediate, profound knee instability (feeling like it will buckle). You will likely be unable to bear weight or continue activity. Only an MRI or a physical, hands-on exam (such as the Lachman test) by an orthopedic specialist can confirm a complete tear.

How to know if an ACL is completely torn?

Symptoms

• A loud pop or a "popping" sensation in the knee.
• Severe pain and inability to continue activity.
• Rapid swelling.
• Loss of range of motion.
• A feeling of instability or "giving way" with weight bearing.

What does a fully torn ACL feel like?

A torn ACL often causes a loud popping sound, sudden swelling, and a feeling of the knee “giving out.” In contrast, a knee sprain may cause milder discomfort and less joint instability. Recovery from an ACL sprain is usually faster and less complex than recovery from a torn ACL.

Can a fully torn ACL heal itself?

The short answer is no; a torn ACL cannot heal on its own because the ligament lacks the blood supply needed for regeneration. Unlike some tissues that have a high blood supply and can repair themselves, the ACL doesn't have the necessary resources to naturally reattach or heal itself once it is torn.

Can you fully bend your knee with a torn ACL?

ACL surgery recovery takes 6 to 12 months for a full return to sports, with general daily activities resuming in a few weeks, but a phased rehab is crucial, starting with crutches/brace (weeks 1-6) for basic strength, progressing to running (3-5 months), and then pivoting/jumping (5-9 months) before competitive sports, to prevent re-injury.
 

Where does your knee hurt with a torn ACL?

Did I tear my ACL or MCL?
