arcuate ligament
The arcuate ligament is part of the posterolateral ligamentous complex of the knee that is variably present, being found in ~65% (range 47.9-71%) of knees. It is a Y-shaped thickening of the posterolateral capsule, which arises from the fibular styloid and divides into two limbs:
- medial limb: curves over the popliteus muscle to join with the oblique popliteal ligament
- lateral limb: ascends to blend with the capsule near the lateral gastrocnemius muscle
In individuals with a large fabella, the arcuate ligament may be absent replaced by a thick fabellofibular ligament.
