Knee Replacement SurgeryNormal knee jointslide 1 of 6 slide 1 of 6, Normal knee joint, Inside a normal knee joint, thick cushioning (cartilage)
covers and protects the ends of your bones. This is called hyaline cartilage.
Another type of cartilage, called meniscal cartilage or meniscus, acts like a
shock absorber between the bones and keeps the knee joint stable by spreading
out the load evenly across the joint. The two menisci (plural of meniscus)
protect and cushion the surface of the joint and the ends of your
bones. Osteoarthritis of the kneeslide 2 of 6 slide 2 of 6, Osteoarthritis of the knee, In osteoarthritis, the cartilage that protects and cushions
the knee joint breaks down over time. As the cartilage wears down, the bone
surfaces rub against each other. This damages the tissue and bone, causing
pain. Osteoarthritis is common in the knee joints. Femoral component is placedslide 3 of 6 slide 3 of 6, Femoral component is placed, Removal of damaged cartilage from the lower end of the femur
