popliteus muscle

All muscles originating on the lower leg except the popliteus muscle are attached to the bones of the foot.

The cyamella is a small sesamoid bone embedded in the tendon of the popliteus muscle.

(For the Popliteus muscle, see above.)

The popliteofibular ligament (PFL) connects the popliteus muscle at the musculotendinous junction to the posterior and medial portion of the fibular styloid.

The arcuate popliteal ligament originates on the apex of the head of the fibula to stretch proximally, crosses the tendon of the popliteus muscle, and passes into the capsule.

This terminal rotation is made possible by the shape of the medial femoral condyle, assisted by contraction of the popliteus muscle and the iliotibial tract and is caused by the stretching of the anterior cruciate ligament.

The popliteus muscle in the leg is used for unlocking the knees during walking/standing by laterally rotating the femur on the tibia (or medially rotating the tibia) during a closed chain movement (such as one with the foot in contact with the ground).

From there it goes to its two insertions; one goes over popliteus muscle and attaches to the intercondylar area of the tibia, the other to the lateral epicondyle of the femur and blends there with the lateral head of gastrocnemius muscle.
