JOURNEY II – Anatomy and Function of the Knee anatomyknee

The three bones that comprise the knee joint are the femur (thighbone), the tibia (shinbone), and the patella (kneecap). The knee may be described as a modified hinge joint, similar to the hinge on a door. However, the knee not only bends back and forth like a hinge, it has a complex rotational component that occurs with flexion and extension of the knee. The knee is a major weight-bearing joint that is held together by muscles, ligaments, and other important soft tissue. Cartilage is the material inside the joint that provides shock absorption to the knee during weight bearing activities such as walking or stair climbing.
