In the knee joint there is a layer of smooth cartilage on the lower end of the femur (thigh bone), the upper end of the tibia (shinbone), and the undersurface of the kneecap (patella). This cartilage serves as a cushion and gliding surface which allows for smooth motion of the knee.
“Arthritis” is a wearing away of this smooth cartilage. Eventually it wears down to bone. Rubbing of bone against bone causes pain and stiffness. For more information on Arthritis, download our Free eBook "Top 10 Ways to Stop Arthritis Pain".
