Arthralgia of the knee joint: symptoms, causes, treatment


Large knee joints are often exposed to severe overloads.The joints themselves have a rather complex anatomical structure, it provides flexion / extension of the leg, its movement in several planes.Moreover, the joint "protects" itself from excessive compression loads and incorrect flexion and extension.

But in some cases, inflammation can occur in these formations. main manifestation of disease is pain - arthralgia .Pain sensations can be quite intense.This is due to the pronounced innervation of the articular formations.

Mechanism of pain in arthralgia of the knee withstava

knee pain may result from direct stimulation of pain receptors.But most often arthralgia is evidence of an inflammatory process in the knee joint or surrounding tissues. Inflammation is a natural reaction of tissues to any diseases and traumatic injuries.Its main manifestations are fever, swelling, pain, redness, dysfunction.The process starts with the special signals given by the cells in the affected area.The role of these signals is played by inflammatory mediators.

After catching them, the body immediately starts exudation, during which the sweat of the fluid rich in protein and leukocytes, called for the destruction of the pathogenic agent, begins from the veins and capillaries near the affected site.So in surrounding tissues the infiltrate accumulates.

The growing edema compresses the vessels, nerves, tissues, which further exacerbates the painful process and intensifies the pain.The formation of tumorous formations - cysts, aneurysms( sack-like enlargements of vessels with thin walls, enlarged lymph nodes) intensify arthralgia.

In practice, there are psychogenic pains in the joints of the knees, the cause of which lies in the features of the nervous system of the patient.

Most often, the inflammatory process involves:

  • cartilaginous tissue and its formations;
  • blood vessels - arteries, veins;
  • nerve trunks and endings;
  • tissue of the lymphatic system - vessels and nodes;
  • muscular-tendon complex;
  • synovial and fibrous tissue capsules;
  • subcutaneous fat;
  • bone formation.

Diagnosis of causes and diseases that cause knee pain( arthralgia)

An experienced specialist -, an orthopedic trauma doctor or rheumatologist , should determine the cause of pain.Laboratory and instrumental diagnostics are preceded by the collection of complaints and examination by a doctor.

Depending on the intended cause, the following is done:

  • arthralgia general blood test ( the doctor is interested in the number of leukocytes and ESR for confirming the inflammatory process, eosinophils for allergic diseases);
  • biochemical blood test .Deviations from the values โ€‹โ€‹of thymol test, the appearance of C-reactive protein, rheumatoid factor, ASL-O, changes in hepatic and renal samples allow the specialist to confirm the presence of certain diseases - rheumatism, oncology processes, kidney disease, liver;
  • radiograph of the knee joint .This method can be supplemented with dynamic fluoroscopy, CT, MRI;
  • of the knee joint ;
  • diagnostic puncture of articular fluid .Allows you to find pathological cells;
  • serological blood tests .To detect allergic and immune diseases;
  • specific research .They are not directly related to arthralgia, but are capable of detecting a possible cause.For example: determining the level of hormones in the blood, smears from the mucous of the genital organs, etc.

Please note : in the absence of obvious possible causes of pain in the knee joints, a doctor may suspect the development of psychogenic rheumatism.

Specific manifestations of arthralgia of the knee in various diseases

arthralgia Pain sensations have some distinctive features in various pathologies.

Deforming arthrosis, which is accompanied by destruction of the cartilaginous tissue, gives a permanent, pain-intensifying pain.It is characterized by frequent nighttime exacerbations, which are accompanied by swelling and redness of the joint.

Inflammation of the popliteal artery or veins is accompanied by a periodicity of pain, with a predominance of stitching paroxysmal variants and the presence of signs of vascular injury, thrombosis.

Inflammation of the popliteal lymphatic formation gives an increase in pain when pressure is applied to it, while wearing tightening clothes.

Traumatic pains in the knee are of a different shade - from drawing, to pronounced.The load can both increase pain in the joint, and vice versa, muffle them.

An erysipelas or dermatitis above the knee area gives a pronounced edema, redness and a burning-licking pain.Sometimes the pain is so severe that the patient can not move the limb with the affected joint.

Inflammation of the synovial bag - bursitis along with pain severely restricts functions in the knee joint.

The infectious nature of joint inflammation - arthritis, is accompanied by severe intoxication of the whole organism.

  • allergic processes. In these cases, arthralgia is eliminated by antihistamine drugs of recent generations( Loratadine), hormone intake( Dexamethasone).Benefits are the use of activated carbon, drugs that can reduce the activity of cells involved in allergic processes - Nedocromil;
  • rheumatic diseases .Combinations of glucocorticosteroids( Prednisolone) and non-steroidal anti-inflammatory drugs( Indomethacin, Ibuprofen) gradually remove the manifestations of arthralgia of the knee joint;
