Anything that puts enough force on your knee to bend or twist it farther than its natural limit can tear your ACL.
The ACL is one of your knee ligaments. It connects your thigh bone (femur) to your shin bone (tibia). You have one ACL in each knee. It forms an “X” shape inside your knee with your posterior cruciate ligament (PCL). The ACL is closer to the front of your knee. The PCL is closer to the back of your knee.
Your ACL is like a strap that connects your bones and prevents your knee from bending or rotating too much. Anything that puts enough force on your knee to bend or twist it farther than its natural limit can injure or tear your ACL.
ACL tears are a common injury, especially among athletes. Visit a healthcare provider if your knee hurts, particularly if the pain started after an injury or physical activity.
An ACL tear is an injury to your knee’s anterior cruciate ligament (ACL).
The ACL is the most commonly injured knee ligament. Sports injuries usually cause ACL tears. If you tear your ACL, you’ll probably need surgery to reconstruct it. Most people who tear their ACL make a full recovery and resume playing sports with no long-term consequences. The recovery time for a torn ACL is usually six to nine months.
ACL injuries are classified into three grades based on severity:
ACL injuries and tears are very common. The ACL is the most commonly injured knee ligament. Experts estimate that between 100,000 and 200,000 people in the U.S. tear an ACL each year.
Most people know the moment they tear their ACL. Sports injuries and other traumas that tear your ACL are usually obvious enough that you can say exactly when it happened.
People who experience an ACL tear usually feel or hear a pop in their knee. Their knee might give out (feel unstable and weak). ACL tears can be very painful, with knee swelling, but some people only feel small discomfort and instability. Visit an orthopaedic doctor if you injured your knee, especially if you hear or feel a popping.
The severity of symptoms depends on the extent of the injury. Some of the most common ACL sprain symptoms include:
Many people report hearing or feeling a loud “pop” when the ligament tears. This is often the first sign of an ACL injury.
Pain is usually felt deep inside the knee, particularly at the centre or along the joint line. It may intensify when trying to bear weight.
Swelling develops rapidly within a few hours due to internal bleeding in the knee. It may cause stiffness, limiting movement.
An injured ACL compromises knee stability, making it difficult to stand, walk, or pivot. Many individuals feel like their knees might “give out.” Difficulty in climbing stairs, specifically Climbing downstairs
Bending or fully straightening the knee becomes painful and difficult due to swelling and joint stiffness.
If left untreated, an ACL tear can lead to chronic knee instability and increase the risk of further injuries, such as cartilage damage requiring cartilage repair.
ACL injuries typically occur due to excessive strain on the ligament. ACL tears happen when your knee moves or twists more than it naturally can. The most common causes include:
Quick turns, pivots, or side-step movements can overstretch the ACL, leading to tears.
Landing awkwardly after a jump increases stress on the knee, putting the ligament at risk.
A sudden blow to the knee, such as in contact sports or car/bike accidents, can rupture the ACL.
Extending the knee beyond its normal range can strain and tear the ligament.
Weak quadriceps and hamstrings fail to support the knee, increasing susceptibility to ligament injuries.
Anyone can experience an ACL tear. They’re much more common among athletes, especially those who play sports that involve suddenly stopping, twisting or changing directions. Some sports that cause frequent ACL tears include:
The injuries that cause ACL tears can damage other parts of your knee, too.

Your doctor might perform some movements or motions with your knee and leg. These tests might feel uncomfortable. Tell your doctor if any position or motion hurts or worsens your symptoms.

For complete ACL ruptures, surgery is often required, especially for active individuals or athletes.
Post-surgical rehabilitation is crucial for regaining full knee function.
Recovery time varies depending on the severity of the injury and treatment method.
A structured physiotherapy program includes strengthening and mobility exercises. These exercises prevent stiffness and ensure the knee regains full function.
