What is the difference between pivot joint and gliding joint?

What is the knee bone called?

Picture of the Knee. The knee is one of the largest and most complex joints in the body. The knee joins the thigh bone (femur) to the shin bone (tibia). The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint.
