How do you know when you retear your ACL?

You may suspect a retear of your ACL if you experience a sudden, sharp pain in the knee, often accompanied by a "popping" sensation. Swelling and instability, making it difficult to bear weight or pivot, are also common signs. Additionally, you might notice a decrease in range of motion and an increase in joint stiffness. If you have had a previous ACL injury, it's important to consult a medical professional for an accurate diagnosis.
