Can't the meniscus injury be detected by X-ray?

X-ray of meniscus injury is difficult to see, which is mainly related to the clarity of the film and the doctor's experience.

It is recommended to have an MRI for the convenience of doctors.

Meniscal injuries are mostly caused by torsional external forces. When one leg is loaded and the calf is fixed in the semi-flexion booth, the body and thigh suddenly rotate inward, and the medial meniscus is between the femoral condyle and tibia, which is subjected to rotational pressure, resulting in meniscus tear.

The greater the degree of knee flexion during sprain, the more backward the tear is. The mechanism of lateral meniscus injury is the same, but the force is in the opposite direction.

If the ruptured meniscus slides between joints, it will cause mechanical obstacles to joint activity, hinder joint extension and flexion, and form an "interlock".

Meniscus injury can occur in the anterior corner, posterior corner, middle part or marginal part of meniscus. The shape of the injury can be transverse crack, longitudinal crack, transverse crack or irregular shape, or even broken into intra-articular free bodies. Classification includes: edge tearing, transverse tearing, longitudinal tearing, transverse tearing and front and rear corner tearing. Under severe trauma, meniscus, cruciate ligament and collateral ligament can be damaged at the same time.

After meniscus injury, the knee joint is painful, unable to straighten automatically, and the joint is swollen. Knee joint space tenderness is an important basis for meniscus injury.

The symptoms of old meniscus injury are mainly knee joint slippage and knee joint locking.

My feet were steady when I slipped, but my knees suddenly slipped. This is easy to happen when going up and down the slope, so patients should be extra careful when going up and down the stairs, step by step.

When you lock it, you suddenly feel that your knees can't bend.

The above situation may be meniscus injury of knee joint, and the specific diagnosis is based on magnetic resonance imaging.

The disease should be differentiated from cruciate ligament and medial and lateral collateral ligament of knee joint.

In diet, we should eat less greasy and high fat, more fruits and vegetables, less flour and rice and more coarse grains.

I hope you get well soon. If you are worried, do an MRI and shake it off ~ ~
