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.
Arthroscopic medial reticular plication with a needle-hole technique is a treatment that uses the less invasive technique of arthroscopy, does not require tissue grafts, and has a greater cosmetic advantage than open procedures. Patellar instability is a common problem resulting in anterior knee pain. The medial patellofemoral ligament, which is part of the medial retinaculum, is often injured, and this damaged structure can affect normal patellar movement. Medial retinacular plication can correct this main pathology of patellar instability.
