What is knee joint tuberculosis?

summary

Simple synovial tuberculosis begins with osteoporosis and soft tissue swelling, and the transparent shadow of the infrailiac fat pad disappears. Bone erosion and destruction can be seen in patients with long course of disease. Knee joint tuberculosis accounts for the second place of bone and joint tuberculosis in the whole body, second only to spinal tuberculosis, and is more common in children and adolescents. Onset is slow, low fever, fatigue, loss of appetite, emaciation, anemia and other systemic symptoms. The knee joint is the largest flexion joint in the whole body. Its articular surface is composed of hemispherical and platform, which is not compatible, unstable and easy to be damaged.

What is knee joint tuberculosis?

1. Children have nocturnal crying. The location of the knee joint is superficial, so the swelling and effusion are very obvious. During the examination, it is found that the knee eye is full, the suprapatellar capsule is swollen, and the floating patella test is positive. In the later stage of knee joint tuberculosis, most of the patients are children and young adults. Most of the patients were unilateral joint disease, and the patients with double joint or multiple joint disease were rare. Patients generally have a history of tuberculosis or tuberculosis contact history.

2. The knee joint is the largest flexion and garrison joint in the whole body. Its articular surface is composed of hemispherical shape and platform, which is incompatible and unstable. It is mainly characterized by inflammatory infiltration and exudation. It is characterized by swelling and effusion of the knee joint. With the development of the disease, tuberculous lesions can invade the bone through the synovial attachment, resulting in marginal bone corrosion.

3. The vast majority of tuberculosis cases are transformed from pulmonary tuberculosis. In the reports of a large number of tuberculosis cases in China, the general symptoms of knee joint patients are usually mild, and the symptoms can be aggravated if combined with other systemic active tuberculosis. The general symptoms include low fever, night sweats, anemia, emaciation, fatigue, fatigue

matters needing attention

Bone destruction grows stealthily along the subchondral area, making the large articular cartilage plate peel off and form total joint tuberculosis. In the later stage, pus accumulates and becomes a cold abscess, which will become a chronic sinus after perforation. The incidence rate of tuberculosis of the knee is second only to that of spinal tuberculosis, and ranks first among the 6 major joints.
