  • most anterior cruciate ligament tears are non-contact twisting injuries

  • blow to the anterior aspect of knee
    • blow to the hyperextended knee:
      • causes include anterior cruciate ligament (ACL) or posterolateral corner injuries
    • blow to flexed knee (such as in a dashboard injury):
      • causes include posterior cruciate ligament (PCL) injury

  • blow to the lateral aspect of knee (valgus injury)
    • results in sudden stretching of medial-sided knee structures
      • superficial medial collateral ligament most at risk for injury

  • blow to the medial aspect of knee (varus injury)
    • increases stress on the outside of the knee
      • possible posterolateral corner injury
