Introduction | History of Empiricism. Empiricism is the theory that the origin of all knowledge is sense experience. It emphasizes the role of experience and evidence, especially sensory perception, in the formation of ideas, and argues that the only knowledge humans can have is a posteriori (i.e. based on experience).
The main anatomic structures of the posterolateral aspect of the knee are the lateral (fibular) collateral ligament (LCL) , the popliteus tendon and the popliteofibular ligament.
The other division of the popliteal artery, the anterior tibial artery, passes anteriorly between the tibia and fibula, through a gap in the interosseous membrane. It then moves inferiorly down the leg. It runs down the entire length of the leg, and into the foot, where it becomes the dorsalis pedis artery.
