osteoarthritis

The articular surfaces of the knee joint are covered with a layer of cartilage. If this gradually wears out, the diagnosis is: knee joint arthrosis. Doctors also refer to this wear and tear as gonarthrosis. It is one of the most common signs of wear and tear on the joints. Cartilage damage in the knee increases the pressure on the underlying bone. To compensate, the joint surface increases and bony tips form at the edge. As a result, the knee joint becomes less mobile and the cartilage damage increases. The bones move closer and closer together and the joint space narrows further. In the late stages, when the bones are almost unprotected and the joint space has completely disappeared, the knee becomes immobile and stiff.
