What is a Torn Anterior Cruciate Ligament?

Known more commonly as a “torn ACL”, the anterior cruciate ligament is one of the four main ligaments found in the knee that works to provide support and motor function to the knee joint. Specifically, the anterior cruciate ligament is one of two ligaments that form an “X”-shape on the inside of the knee joint to prevent the knee from sliding back and forth. When the ligament becomes sprained, the fibers become stretched or torn. Typically, a second-degree sprain is considered a partially-torn ligament while a third-degree sprain is defined as a fully torn ligament.


The primary cause of a torn anterior cruciate ligament is injury, nearly always due to playing sports or participating in fitness activities. Because this tear most often occurs when the knee locks and twists or experiences a sudden change in movement or direction, these injuries are quite common in basketball, soccer, football, gymnastics and even skiing.

Other potential causes that are not as common, but still hold the possibility of tearing your anterior cruciate ligament, include:

  • Congenital abnormalities, such as a narrow femoral notch
  • Unexpected trauma or accident, such as a fall or misstep
  • Inactivity and lack of exercise, which eventually causes weak leg muscles and makes the knees more prone to injury


Symptoms of a torn anterior cruciate ligament include:

  • Feeling or hearing a “pop”-like sound in the knee at the time of injury
  • Instability in the knee, such as buckling or the feeling that it may “give out”
  • Pain and swelling
  • Limited mobility

Oftentimes, patients realize the moment they have torn their anterior cruciate ligament. Swelling may occur within the first few hours post-injury and is usually a sign of bleeding inside the knee joint. If you believe you may have stretched or torn your anterior cruciate ligament, it is important to seek immediate medical attention. Prompt, proper care can go a long a way in avoiding chronic discomfort and long-term damage that can adversely affect your future mobility and athletic career.
