What does a torn ACL feel like, and what are the signs?

In the first hours and days

• A pop or tearing feeling deep inside the knee
• Swelling that builds over two to twelve hours, from bleeding into the joint
• Pain deep in the knee rather than at one precise spot
• Being unable to carry on with the game
• Difficulty straightening the knee fully or bending it far
• Feeling unsteady or reluctant to put full weight through the leg

Weeks later

Once the swelling goes down, many people walk normally and wonder if they were wrong. The typical complaint then is instability: the knee shifts or buckles when turning, stepping off a kerb, going down stairs, or changing direction in sport. Patients say it feels loose, wobbly or untrustworthy. Each episode may be followed by fresh swelling and soreness for a few days.

Symptoms that suggest something else as well

Locking, where the knee gets stuck and will not straighten, or sharp pain along the joint line when twisting, suggests a meniscus tear alongside the ACL injury. Marked tenderness on the inner side can mean an MCL injury. A deformed knee, numbness or a cold foot after a high-energy injury is an emergency and needs the nearest emergency department straight away.

Confirming the diagnosis in Doha

Symptoms point the way, but examination confirms it. At Aman Hospital, Dr. Gelber uses ligament tests such as the Lachman and pivot shift tests and, where it will change the plan, an MRI to look at the ACL, meniscus and cartilage together. Booking within the first couple of weeks helps plan rehabilitation or surgery early.
