📌MRI Findings in Ligament Injuries

 

Classification of Ligament Injuries

  • At MR imaging, ligament injuries can be classified as:
  • These often correspond to the clinical grading of grade I, II, and III injuries, respectively.

 

Lateral Collateral Ligament (LCL) Injury Patterns

  • Most common injury patterns of the fibular collateral ligament (LCL) include:
  • According to Juhng et al., avulsion of the LCL usually occurs at its distal attachment from the head of the fibula, rather than its proximal femoral attachment.
  • In complete LCL disruptions, the ligament demonstrates a wavy or serpiginous contour and loss of ligamentous continuity on MRI.

 

Associated Cruciate Ligament Injuries

  • Isolated injuries to the posterolateral corner (PLC) of the knee are rare.
  • PLC injuries usually occur in conjunction with injury to a cruciate ligament (ACL or PCL).
