Risk factors for ACl injuries

What are the risk factors for ACL rupture in non contact sports?

It is known that women are at a 4 to 6 times greater risk for sustaining a non-contact ACL injury compared to a male

Risk factors can include environmental, hormonal, neuromuscular, anatomical. These include:

  • Weather : Dry weather could increase the friction coefficient and torsional resistance from the shoe-surface interface.
  • Type of foot wear
  • Playing surface
  • Sport

What other factors increase our risk of non contact ACL injuries?

  • Weak hamstrings
  • Muscle fatigue
  • Decreased core strength
  • Decreased proprioception
  • High dorsiflexion of ankle
  • Low trunk, hip, knee flexion angles


These are important things to take into consideration when starting a prehab program. Be sure to build into your usual training hamstring strengthening exercises, core strength training and proprioceptive education.
