Your Knee and Osteoarthritis

ImageThe knee joint is formed where the femur (thigh bone), tibia (shin bone) and patella (knee cap) come together. The intersection of these bones forms three “compartments”:

  • Medial compartment (inner half of the knee)
  • Lateral compartment (outer half of the knee)
  • Patella femoral compartment (behind the knee cap)

In a healthy, functioning knee, each bone glides smoothly over the others on a layer of cartilage that covers the ends of the bones. In a knee joint affected by osteoarthritis (OA), this cartilage can break down and wear away, causing the bones to rub together resulting in extreme knee pain.

OA is a degenerative joint disease and the most common form of arthritis, affecting tens of millions of people worldwide. OA resulting from “wear and tear” of the knee cartilage is the most common reason patients need to undergo knee replacement. Your doctor can determine the extent and severity of your OA.
