Arcuate popliteal ligament
The arcuate popliteal ligament is a thick and fibrous band that is connected from above to the femur's lateral condyle. The ligamentous band has a triangular shape, and is a lower limb joint. It is a variable cluster of fibers that is located on the fibrous joint capsule's posterior edge. The ligament is characterized by a small attachment on the fibula's head. The attachment transmits posterior and anterior slips that combine together with the joint capsule. It fuses both the posterior tibial intercondylar area and the lateral femoral epicyondyle areas together. The broad band travels in a downward and medial direction, while simultaneously mixing in with the fibrous capsule's (within the knee joint) back section. The band arches directly over the popliteus muscle's tendon and travels to the area in between the tibia and the condyles on its way to the fibula's head. The arcuate popliteal ligament is situated in close proximity to the fibular collateral ligament, the oblique popliteal ligament and the fibula.
