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.
Place the probe transversely at the knee crease in the popliteal fossa. Locate the popliteal artery and vein. Check the compressibility of the popliteal vein throughout the popliteal fossa. Be cautious not to mistake the often prominant muscular veins (gastrocnemius veins) for the popliteal vein. Whislt not truely deep veins they are generally large and still pose a lesser risk of embolisation. As such, you should also examine these as possible causes of the patient's symptoms.
