The meniscofibular ligament is a capsular ligament that connects the corpus of the lateral meniscus to the fibular head and provides stability to the posterolateral corner of the knee.

Gross anatomy
The meniscofibular has been shown to be present in up to 100% of cadaver studies 1,2. It consists of dense connective tissue and forms a connection between meniscus and bone similar to the adjacent meniscotibial ligaments. It inserts to the inferolateral portion of the lateral meniscus anterior to the popliteus tendon and the apex of the fibular head 1-5.
Function
The meniscofibular ligament transmits movements from the fibula and the ankle to the lateral meniscus and is believed to have a protective effect during the last stages of knee extension 1,2.
Radiographic features
MRI
The meniscofibular ligament can be identified on sagittal images in about half of the individuals taking its course between the posterior third of the lateral meniscus and the apex of the fibular head 3,4.
History and etymology
The meniscofibular ligament was first described by S Zivanovic in 1964 2,5.
Clinical importance
The meniscofibular ligament and the anteroinferior popliteomeniscal fascicle might very well be the same anatomical structure – however, this has to be confirmed!
