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 anterior talofibular ligament is injured first, followed by injury to the calcaneofibular ligament and posterior talofibular ligament. Since the anterior talofibular ligament is the weakest ligament in the lateral ankle complex, it is most commonly injured as a result of plantarflexion and inversion injuries.
