The knee joint joins the thigh with the lower leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest joint in the human body and is very complicated. The knee is a mobile trocho-ginglymus (a pivotal hinge joint), which permits flexion and extension as well as a slight medial and lateral rotation. Since in humans the knee supports nearly the whole weight of the body, it is vulnerable to both acute injury and the development of osteoarthritis.

It is often grouped into tibiofemoral and patellofemoral components. (The fibular collateral ligament is often considered with tibiofemoral components.)

Famous quotes containing the word knee:

    He has no resolution, he shrinks from pain or labour in any of its shapes. His very attitude bespeaks this: he never straightens his knee joints, he stoops with his fat ill- shapen shoulders, and in walking he does not tread but shovel and slide.
    Thomas Carlyle (1795–1881)
