Deficiency of interleukin 10 (IL-10), secreted during motion, may also contribute to the pathogenesis of degenerative changes in this mechanism ( 10). Unloading, particularly immobilization, the pathogenic mechanism of which consists mainly of insufficient nutrition of the cartilage, may be an inverse factor in the damage. These changes initiate a local immune response at the site of injury, leading to synovitis and development of degenerative changes ( 9). Excessive loads cause destruction of cartilage tissue, which, over time, leads to apoptosis and changes in the cartilage structure. Ageing chondrocytes lose their synthetic ability, resulting in the production of irregular aggrecan molecules ( 6- 8). Age-related chondropaenia (glycation of collagen and deposition of pyrophosphate crystals) leads to an increase in the susceptibility of cartilage to injury. Modifications in the subchondral tissue also occur, in which, in the course of GA, thickening of the subchondral layers and sclerosis (hardening) are observed ( 4, 5). With age, cartilage loses the ability to regenerate, resulting in inflammation, pain and limitation of joint mobility. The correct biomechanics of the knee joint protects the joint against excessive strain. Genetic factors, hormonal changes (menopause), nutritional neglect (a diet lacking vitamin D, C, E and mineral supplements, excess carbohydrates and trans-fats), previous knee injuries, physical (recreational or professional) activity involving the knee joints or requiring a forced position of the body may contribute to degenerative changes ( 2, 3). Medial: the most common form, consisting of narrowing of the articular space between the condyles of the femur and the proximal epiphysis of the tibia on the medial side often associated with bow legs (genu varum) ( 2).īased on the aetiopathogenesis of the disease, primary (idiopathic) and secondary forms are distinguished. Three forms of the disease are distinguished according to the location of degenerative changes: Gonarthrosis (GA) is the most frequent form of osteoarthritis.

The above definition of OA was set out by experts of the American Academy of Orthopedic Surgeons National Institute on Aging National Institute of Arthritis and Musculoskeletal and Skin Diseases ( 1). OA is a chronic disease with periods of exacerbation and remission. The clinical manifestations of OA include joint pain, locomotor restriction, pain on palpation, joint crepitation, exudates, and inflammation without systemic symptoms.

The years 20002010 were designated by the World Health Organization (WHO) and the United Nations Organization (UNO) as the bone and joint decade.

OA is one of the most common diseases of the musculoskeletal system and is termed a civilization disease of the 21 st century. Osteoarthritis (OA) is a group of multiple overlapping pathological conditions that lead to the destruction of articular cartilage.
