Title: Functional Anatomy in Knee Osteoarthritis: Patellofemoral Joint vs. Tibiofemoral Joint
Abstract: “Knee Joint Osteoarthritis” is the topic chosen for the first editorial of the second volume of this journal. The aim of this editorial is to discuss this interesting but little analyzed topic in the current literature, in order to explain and help readers to better understand the functional anatomical aspects of knee joints affected by Osteoarthritis (OA). As the knee joint is tricompartmental, numerous radiographic patterns of disease are possible and the differences between the two main compartments of the knee (patellofemoral joint versus tibiofemoral joint) are explored in this editorial.
