Symptoms of chronic meniscus injury

summary

Last week, I fell when I was playing with my colleagues. I felt special pain in my leg joints. Recently, I was too swollen to walk. I went to the hospital for examination. The doctor said it was a symptom of meniscus injury.; What are the general symptoms of meniscus injury? Let's share it here.

Symptoms of chronic meniscus injury

The so-called meniscus injury is a kind of knee or joint, limited pain, some patients will appear soft legs or knee joint locking phenomenon, so usually meniscus injury, quadriceps atrophy, knee joint space fixed limited tenderness as the main symptoms.

There are many reasons for meniscus injury, but most of them are caused by external torsion force. When one leg is loaded and the leg is fixed in the semi flexion and abduction position, the body and thigh will rotate abruptly. Because the medial meniscus is subjected to the pressure of rotation between the femoral condyle and tibia, the meniscus tears.

If the diagnosis is doubtful before operation, arthroscopic examination should be performed. According to the microscopic findings and clinical manifestations, the operation plan should be selected, which should be performed under arthroscopy or arthrotomy. For the patients with obvious quadriceps atrophy, they were asked to exercise the quadriceps before operation; If there is more effusion in the knee, it is necessary to reduce the activity of the knee joint before the operation. Local treatment should be carried out, and the operation should be carried out after the effusion subsides.

matters needing attention

Meniscus injury is more common in ball players, miners, porters and so on. When the knee joint is fully extended, the medial and lateral collateral ligaments are tense, the joint is stable, and the chance of meniscus injury is less. When the lower limbs are loaded, the feet are fixed, and the knee joint is in the semi flexion position, the meniscus moves backward. If the knee is suddenly extended by excessive internal rotation or external rotation, the meniscus will be squeezed before it has time to retreat, which can cause injury and tear.
