As a child, we begin to injure ourknees. There were scratches, there were no scratches on the knees of a rare child. In everyday life they say "broke my knees". But, if the knees really broke, then the majority would be provided with lifelong disability. Constantly testing for the strength of the largest and complex joints - the knee, we notice them when we begin to experience pain in the knees. With age, this happens to almost everyone.
Minor and fast pains, ifthey do not pay attention, intensify. When the knees ache is limited mobility of the joints, there is stiffness in the movements. Often the knee swells and turns red. The pain becomes almost constant, exacerbating at night. Why is this happening? Diseases of the knee joint are so many, they are so diverse that only a doctor can answer this question.
Immediately determine why it hurts under the knee,is impossible. At least because the knee joint consists of bones, cartilage, tendons, ligaments, muscles, interarticulate fluid. And what has become inflamed, deformed, injured, worn or swollen, can be recognized only after a thorough examination, tests and tests.
Some people are concerned about local pain under the kneeback. When you see a doctor, patients complain of a feeling of stiffness, pressure in the popliteal fossa. Painful sensations may be absent, but discomfort is present all the time.
Pain under the knee at the back can be causedpopliteal tumor - cyst. This disease is called Baker's disease. At first, the cyst is little noticeable, it is determined only by the method of palpation, palpation. When the leg is unbent, it is more noticeable, when bending, it almost disappears.
Cyst Baker is a dense tumor, soft and elastic to the touch. The skin above the swelling is not inflamed, it looks absolutely healthy. This benign formation is filled with fluid.
To provoke the appearance of Baker's cystvarious diseases of the knee joint: arthrosis of different etymology, arthritis, synovitis. Often the cause of joint tumors in the popliteal calyx are meniscus injuries, cartilage damage.
Sometimes the appearance of a cyst occurs without apparent subjective reasons.
Pain under the knee at the back begins especiallybother the person when the cyst acquires considerable dimensions. The accumulated fluid squeezes adjacent blood vessels, nerve trunks, blood circulation is disturbed. There is numbness of the leg, the skin becomes colder under the knee, edema appears.
In the absence of treatment, the Baker cyst may causeserious complications, promote the development of deep vein thrombophlebitis of the lower leg 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 an increase in the temperature of the adjacent tissues.
For diagnosing Baker's cyst is importantdetermining the root cause of the disease. The patient is fully examined, in addition to conventional tests, he is assigned ultrasound and magnetic resonance imaging of the knee joint. The method of puncture - a puncture of the wall of the cyst, the patient makes an analysis of the contents of the tumor.
Treatment of "young" cysts is usually conservative: The syringe is sucked off the contents, then anti-inflammatory drugs are injected into the same hole. Also, the underlying disease of the knee joint, which caused the tumor, is actively treated. If the tumor has reached a significant size, then conservative treatment is not always effective. In this case, surgical intervention is prescribed.
The pain under the knee at the back is not always a symptom of Baker's cyst, the reasons may not be so serious. But, to be convinced of this, it is necessary to consult with the doctor.
