Name
- Posterior meniscofemoral ligament (PMFL)
- Wrisberg ligament
- Meniscofemoral ligament of Wrisberg
- Posterior meniscal ligament
- Meniscofemoral ligament
General
- Small ligament in the knee joint, part of the meniscofemoral ligaments
- Arises from posterior horn of the lateral meniscus
- Passes superomedial and behind 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 65% of patients[6]
MRI Features
- Best visualized in coronal and sagittal planes
Clinical Significance
- Meniscofemoral ligament tear
- May be mistaken for meniscus tear, loose body
