3 A Worn Knee Joint The smooth cartilage layers can wear down on the ends of the bones. The cartilage can wear down as you age or from injury, arthritis, or a side effect from certain medicines. When the bone surfaces and cartilage wear down, they become rough, like sandpaper. As you move your leg, the bones grind and you have pain and stiffness. Movement of knee cap Bone spurs Worn, cracked cartilage Narrowed joint space Total Knee Replacement During surgery, the damaged cartilage and ends of the bones of the knee joint are removed. A new joint is created using an artificial joint made of metal and very strong plastic. Parts of the new joint may be cemented in place with special bone cement.
