How a Football ACL Tear Happens: The Injury and Its Treatment
A torn anterior cruciate ligament (ACL) is one of the most famous injuries in football. In this video, Dr. Amr Elyamany discusses the injury reported for the defender Lucas Hernández and uses it to explain how these tears happen and are treated.
How it happens
The typical picture is a foot planted on the ground when the knee suddenly twists. That sudden twist can tear the ACL, and sometimes the inner (medial) ligament of the knee as well.
What follows immediately
- The pain is very severe, so the player stops playing at once.
- The knee is immobilised temporarily.
- An ice pack is applied to reduce swelling and pain.
The usual treatment
For most athletes, the ACL is treated with arthroscopic (keyhole) surgery to repair or, more commonly, reconstruct the torn ligament, followed by a structured rehabilitation programme before returning to play.
Key takeaway: A twisting knee with severe pain and swelling needs urgent assessment: the earlier the diagnosis, the better the plan.
When to see a doctor
- A pop, sudden severe pain or swelling after a twist
- A knee that cannot bear weight or feels unstable
- Any football or pivoting injury that does not settle within days
