It may come as a surprise, but the knee joint is actually the body's largest joint. Known as a 'hinge' joint because it only allows the lower leg to move backwards, the knee must support nearly the entire weight of the human body, explaining its large size. An extensive network of ligaments connecting bone to bone holds the knee joint in place. Additionally, cartilage-rich meniscuses between the upper and lower leg act as the body's main shock absorber. With so many bones and ligaments, and so much cartilage, it makes sense that the knee is the body's largest and most complex joint.
