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.
popliteal pulse one palpated in the popliteal fossa, most easily detected when the patient is lying prone with the knee flexed about 45 degrees. posterior tibial pulse a pulse felt over the posterior tibial artery just posterior to the ankle bone on the inner aspect of the ankle.
