The joint of the knee is formed by the femur, on the one hand, and on the other, the tibia and the fibula. These surfaces are upholstered by the particular cartilage. Osteoarthritis of the knee is characterized by the gradual deterioration of this cartilage and leads to the onset of pain with physical activity, variable inability to walk and stand, as well as progressive deformity of the knee. In general, it is typical of older people, although it can appear before the age of 50, being exceptional in young people.
As in osteoarthritis affecting other joints, the most frequent symptoms are pain, stiffness; deformity and loss of functionality are few of knee pain symptoms. It is characteristic of osteoarthritis of the knee to have pain and stiffness when trying to get up, after sitting for a while. This pain and stiffness disappear initially with the first steps but reappears after walking a more or less variable distance. The pain is gradually giving way with rest.
