Knee Anatomy

Knee Anatomy

Your knee joint is formed by the intersection of the femur (thigh bone), the tibia (shin bone) and patella (knee cap). These bones form three “compartments” or sections.

Parts of the knee:
  1. Femur
  2. Patella
  3. Cartilage
  4. Tibia

Osteoarthritis (OA) is a degenerative joint disease characterized by the breakdown and wearing away of cartilage causing the bones to rub together and result in pain. It can affect all of the knee or just parts, depending on the severity.

Osteoarthritis in the knee is a painful condition that can be relieved by knee surgery. A partial knee replacement (PKR) is an option for people who have osteoarthritis in one or two compartments of the knee. A total knee replacement (TKR) is an option for people with osteoarthritis in all three compartments.
