Corpus: Fabellofibular ligament

The fabellofibular ligament is a ligament that runs vertically from the fabella towards the styloid process of the fibula and inserts at its tip.

The fabellofibular ligament runs parallel to the medial collateral ligament. If the fabella is missing, the origin of the ligament can also lie on the lateral femoral condyle.

The formation of the fabellofibular ligament and the popliteal arcuate ligament are negatively correlated. If the arcuate ligament is very pronounced, the fabellofibular ligament is usually only weakly present. Conversely, the arcuate ligament may be absent in the case of a large fabella.
