pMFL Anatomy¶
This section describes the Posterior Meniscofemoral Ligament (pMFL) anatomy, including the femoral insertion sites.
General Description¶
The Posterior Meniscofemoral Ligament (pMFL), also known as ligament of Wrisberg, extends from the posterior horn of lateral meniscus to medial femoral condyle and lies posterior to PCL. It is usually larger than ligament of Humphrey [noa18]. The average ratio of the cross sectional area of Wrisberg to that for the PCL within the same knee is 12.0 ± 7.7% [KHC+94].
- Femoral insertion: It inserts at the medial part of the intercondylar notch near to insertion of the posteromedial band of the PCL. This is the reason why fibers of the pMFL and PCL sometimes intermingle [noa18].
- Meniscal insertion: The meniscal attachments of the pMFL followed its orientation in the sagittal plane and attaches to posterior horn of lateral meniscus
- length: 31.2 mm (range, 27.0-40.0 mm) [YH91].
