Your knee is a hinge joint where the end of the thigh bone (femur) meets the beginning of the large bone in your lower leg (tibia). A healthy knee has smooth cartilage that covers the ends of the femur and tibia. The smooth cartilage lets the surfaces of the two bones glide smoothly as you bend your knee. The muscles and ligaments around the knee joint support your weight and help move the joint smoothly so you can walk without pain.
The smooth cartilage layers can wear down on the ends of the femur and tibia. When the smooth surfaces become rough, the surfaces are like sandpaper. Instead of the joint gliding when you move your leg, the bones grind and you have pain and / or stiffness.
This degeneration can happen due to variety of reasons such as the following:
When pain in your knee or leg prevents you from doing your usual activities and your x-rays show irregular surfaces at the knee, your doctor might suggest that you have a knee replacement.
