Anterior Cruciate Ligament (ACL) Injuries

Font Size

What Increases Your Risk

Things that increase your risk of anterior cruciate ligament (ACL) injuries include:

  • Playing sports that involve sudden changes in direction or cutting around other players or obstacles, such as skiing, football, soccer, basketball, baseball, and tennis.
  • Making accidental movements that may twist your knee. Examples include falling off a ladder, jumping from an extreme height, stepping into a hole, or missing a step on a staircase.
  • Losing muscle tone in legs (from aging or inactivity).
  • Having unbalanced leg muscle strength, such as if the muscles in the front of your thigh (quadriceps) are stronger than the muscles at the back of your thigh (hamstrings).
  • Previous ACL injuries, especially if your knee sometimes gives out or buckles (chronic ACL deficiency).

Women have more ACL injuries than men.1
