Anterior Meniscofemoral Ligament
Description
Name
- Anterior Meniscofemoral Ligament (aMFL)
- Ligament of Humphry
General
- Small ligament in the knee joint, part of the meniscofemoral ligaments
- Arises from posterior horn of the lateral meniscus
- Passes superomedial to the posterior cruciate ligament
- Inserts on the lateral surface of the medial femoral condyle
Function
- Contributes to stabilization of the posterolateral part of the lateral meniscus
- Helps pull lateral meniscus anteromedially during flexion
- Improves congruence of lateral compartment, decreasing contact pressure
- Protective role of the PCL
Anatomic Variance
- Reportedly present in approximately 60% of knees on cadaveric studies (need citation)
- Found in 12%-50% of subjects on MRI[3]
- 3T studies showed a higher prevalence than 1.5T MRI[4]
MRI Features
- Best visualized in coronal and sagittal planes
Clinical Significance
- Can mimic a meniscus tear
