Arthralgia of the knee joint: symptoms, causes, treatment

Large knee joints are often subjected to high overloads. The joints themselves have a rather complex anatomical structure, it provides the flexion/extension of the legs, its movement in multiple planes. Moreover, the joint “protects” itself from excessive compressive loads and incorrect flexion and extension.

But in some cases these entities may occur inflammation. The main manifestation of the disorder is pain – arthralgia. Pain can be quite intense. This is due to the pronounced innervation of articular structures.

The mechanism of occurrence of pain with arthralgia of the knee joint

Pain in the knees can occur as a result of direct irritation of pain receptors. But most often arthralgia – evidence of an inflammatory process in the knee joint or surrounding tissues. Inflammation is a natural reaction of tissue to any diseases and traumatic injuries. Its main symptoms – fever, swelling, pain, redness, impaired function. The process begins with the particular signals supplied by the cells in the affected area. The role of these signals perform the mediators of inflammation.

Catching them, the body immediately starts the exudation, during which the veins and capillaries near the affected area begins the exudation of fluid rich in protein and white blood cells designed to destroy disease-causing agent. So in the surrounding tissues accumulates infiltration.

Increasing swelling compresses blood vessels, nerves, tissues, exacerbating the painful process and increases the pain. The formation of tumor-like formations – cysts, aneurysms (use increases blood vessels with thin walls, enlarged lymph nodes) increase the arthralgia.

In the practice of psychogenic pain in the joints of the knees, the cause of which lies in the peculiarities of the nervous system of the patient.

Most often in the inflammatory process involved:

  • cartilage and its formation;
  • blood vessels – arteries, veins;

  • biochemical analysis of blood. Deviations from the values of thymol samples, the appearance of C-reactive protein, rheumatoid factor, ASL-O, changes in liver and kidney samples allows the technician to confirm the presence of certain diseases, rheumatism, oncological processes, diseases of the kidneys, the liver;
  • radiography of the knee joint. This method can be complemented by dynamic fluoroscopy, CT, MRI;
  • Ultrasound of the knee joint;
  • diagnostic puncture of the synovial fluid. Allows you to find the abnormal cells;
  • serological blood tests. For detection of allergic and immune diseases;
  • specific investigations. They are not directly associated with arthralgia, but is able to detect the possible cause. For example: to determine the level of hormones in the blood, smears from mucosa of the genital organs, etc.
