Osteoarthritis is a degenerative-dystrophic lesion of the joint, involving mainly cartilage, epiphyses of bones, and to a lesser extent soft tissues.

Arthrosis distinguishes between primary and secondary. Primary arthrosis develops in the unchanged joint. Secondary arthrosis - manifests itself on the basis of previous diseases and pathological conditions of the joint.

Causes of the origin of primary arthrosis have not been fully elucidated. Among the factors contributing to the development of local manifestations of the disease, the first place is occupied by the static load exceeding the joint capabilities, and mechanical microtraction. With age, changes occur in the vessels of the synovium. An important role is also assigned to some endocrine disorders, especially an increase in the activity of the growth hormone of the pituitary gland, a decrease in the function of the thyroid and sex glands.

With obesity, not only does the mechanical load increase on the joints of the lower limbs, but also the general effect of metabolic disturbances on the function of the musculoskeletal system.

In addition, the importance of infectious, allergic and toxic factors.

A definite role of the pathology of the crural veins in the development of arthrosis of the knee joints.

There are also data indicating the role of heredity in the origin of osteoarthritis.

Secondary arthrosis usually develops with congenital or acquired inferiority of cartilage and other elements of the joint, increased static load, endocrine-metabolic disorders, infectious-toxic effects and t.

Symptoms Primary arthrosis is often accompanied by a violation of fat metabolism, arterial hypertension, atherosclerosis and other diseases. Articular arthrosis symptoms consist of pain, feelings of stiffness, rapid fatigue, stiffness, deformities and other. Pain, usually dull. They are fickle, intensified in damp cold weather, after a prolonged load and with initial movements after a state of rest.

In the hip joints, the pain is given to the inguinal or to the ischium (with the tension of the deflecting muscles and flexors of the thigh).

Very often, especially with senile arthrosis, instead of pain, only aches and feelings of heaviness in the bones and joints. This sensation is very close to a feeling of stiffness in rheumatoid arthritis, but it is characterized by short duration and low intensity. The true limitation of mobility with arthrosis is rare, more often it is a question of stiffness and rapid fatigue of the joints.

The disease is manifested by pain at movement, restriction of mobility in joints, etc..
