Athletic Activities

Athletic activities are the most common cause of ACL injuries. An anterior cruciate ligament injury refers to the overstretching of the ACL in your knee. It can be a complete tear or a partial tear.

There are many ways that athletic activities can cause this type of injury, and it can occur in contact and non-contact sports.

San Francisco knee doctor James Chen, MD, often sees it as a result of pivoting or cutting maneuvers, like when you plant your foot and suddenly shift in another direction.

ACL injuries can also occur from stopping suddenly when running or landing on one leg when jumping in basketball or volleyball.

You can also injure your ACL if your knee gets hit directly, especially if it is bent slightly inward or is extended further than normal at the time of impact. Repeated stress can also cause an ACL injury because it can cause the ligament to lose elasticity.

An ACL injury may also occur if you twist or bend your knee backward.

Sudden Impacts

A sudden direct impact on the knee is another common cause of an ACL injury. Sudden impacts can occur during various physical activities and while playing sports, especially contact sports. But sudden impacts to the knee can also happen if you trip and fall or if you are involved in a car accident.

The worst of these injuries occur when your knee is over-extended or bent inward.

ACL tears from sudden impacts often occur together with other injuries to the knee tissues, including other ligaments and cartilage.

Overextending a Joint

Hyperextension happens when you force your knee joint to extend beyond its natural range of motion. This puts a lot of stress on one of the four major ligaments, including the ACL. This type of overextension can happen to anyone, but it is more common in athletes who play games like:

  • Lacrosse

  • Soccer

  • Football

Skiing can also cause ACL injuries because it can cause your knee joint to suddenly move out of position.

Overextending the joint can cause other soft tissue damage and swelling, along with ACL tears.

Unexpected impacts to the front of the knee are another concern. This causes the knee joint to move backward beyond what it can normally handle, leading to a partial or full tear.

Overextension occurs on a spectrum, with mild injuries causing the affected knee to lose some of its stability, giving you the sensation that it could buckle at any moment.

More severe injuries can make it impossible to move the knee, resulting in severe pain and swelling.
