The Knee

The knee is one of the most complex joints in the body, it supports much of our weight.

However, because of this it is prone to injury. The knee joint is made up of three bones, Femur (thighbone), Patella (knee cap), and Tibia (shinbone). These bones are connected by muscles, ligaments and tendons. The knee straightens and bends in one direction, and is known as a hinge joint. In order for the knees to move smoothly, the bones are covered in a protective tissue called articular cartilage. If the cartilage is diseased as in osteoarthritis, damaged by injury  or worn out, the bones rub against each other causing pain and stiffness in the knee.
