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.
Fig 1.1 â Muscles in the deep layer of the posterior leg. The popliteus is located superiorly in the leg. It lies behind the knee joint, forming the base of the popliteal fossa. There is a bursa (fluid filled sac) that lies between the popliteal tendon and the posterior surface of the knee joint.ig 1.1 â Muscles in the deep layer of the posterior leg.
