Structure
The popliteofibular ligament extends from the musculotendinous junction of popliteus muscle. It passes inferiorly to insert into the apex of the head of the fibula, adjacent to the insertion of the lateral collateral ligament.
In its distal two thirds, the orientation of the fibers are almost vertical and similar to that of the fibular collateral ligament. In its proximal one third, the fibers are oriented more obliquely as it blends with the tendon of the popliteal muscle.

Function
The popliteofibular ligament is an important stabilizer of the posterolateral knee. It resists posterior translation and external rotation of the tibia (Standring, 2016).
