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 medial patellofemoral ligament, which is part of the medial retinaculum, is often the main structure involved in injuries, especially in normal knee alignment. Therefore medial retinacular plication corrects this main pathology of patellar instability.
