As a child, we begin to injure our knees. A rare child had no abrasions or scratches on his knees. In everyday life they say "broke my knees." But, if indeed the knees were broken, then the majority would have been provided with a lifelong disability. Constantly testing for strength the largest and most complex joints - the knee, we notice them when we begin to experience pain in the knees. With age, this happens with almost everyone.
Minor and rapidly passing pains, if you do not pay attention to them, intensify. When the knees hurt, the mobility of the joints is limited, stiffness in movements appears. Often the knee swells, turns red. The pain becomes almost constant, worsening at night. Why is this happening? There are so many diseases of the knee joint, they are so diverse that only a doctor can answer this question.
Immediately determine why it hurts under the knee, it is impossible. If only because the knee joint consists of bones, cartilage, tendons, ligaments, muscles, interarticular fluid. And what of this inflamed, deformed, impaired, worn out or swollen, can be found only after a thorough examination, analysis and tests.
Some are concerned about the local pain under the knee in the back. When contacting a doctor, patients complain of a feeling of stiffness, pressure in the popliteal fossa. In this case, pain may be absent, but discomfort is constantly present.
Pain under the knee in the back can be caused by a popliteal tumor - a cyst. This disease is called Baker's disease. At first, the cyst is not noticeable, it is determined only by palpation, palpation. When the leg is extended, it is more noticeable; when bent, it almost disappears.
Baker's cyst is a dense tumor, soft and elastic to the touch. The skin over the swelling is not inflamed, it looks completely healthy. This benign mass is filled with fluid.
Various diseases of the knee joint can provoke the appearance of Baker cysts: arthrosis of various etymologies, arthritis, synovitis. Often the cause of a joint tumor in the popliteal cup is meniscus injury, cartilage damage.
Sometimes the appearance of a cyst occurs without apparent subjective reasons.
The pain under the knee in the back begins to especially disturb the person when the cyst becomes significant. The accumulated fluid compresses adjacent blood vessels, nerve trunks, blood circulation is disturbed. Numbness of the legs occurs, the skin gets colder below the knee, swelling appears.
If untreated, Baker's cyst can cause serious complications, contribute to the development of deep vein thrombophlebitis and varicose veins. Especially dangerous is the rupture of the cyst wall. When this happens, there is a sharp pain under the knee, redness and fever of adjacent tissues.
To diagnose Baker's cyst, it is important to determine the root cause of the disease. The patient is fully examined, in addition to conventional tests, he is assigned an ultrasound scan and magnetic resonance imaging of the knee joint. By a puncture method - a puncture of a wall of a cyst, the patient is analyzed with the contents of the tumor.
The treatment of the “young” cyst is usually conservative: the contents are sucked off with a syringe, then anti-inflammatory drugs are injected into the same hole. The underlying disease of the knee joint that caused the tumor is also actively treated. If the tumor has reached a significant size, then conservative treatment is not always effective. In this case, surgery is prescribed.
Pain under the knee in the back is not always a symptom of a Baker cyst, the causes may not be so serious. But to make sure of this, you should consult a doctor.
