1, the performance of meniscus injury

Knee joint pain, swelling, limited mobility, soft leg and "wrist lock" when walking, rebound during flexion and extension, knee joint gap tenderness during examination, positive McKee sign (inspector holding the foot in one hand, placed in one hand In the knee, the calf is firstly circulated and then advected and straightened, and then the calf is externally rotated and abducted, and then the intestine is straightened, and if there is pain or a snap, it is positive.).

2, the cause of the damage

Repeated compression, torsion, and wear of the knee are a common cause of damage and tear. Just like repeatedly using a pencil with a rubber head to wipe the wrong writing on the paper, the rubber head often breaks before the pencil is used up. same. If you haven't used such a pencil, you will repeatedly twist when you eat Oreo biscuits, you will see the middle sandwich broken, in fact, the meniscus is sandwiched between the femur and the tibia, and the damage occurs. The reason is the same. Acute sprains of the meniscus often occur during sports.

3. What do I need to check?

1. X-ray examination The purpose of the radiography is not to diagnose meniscus tears, but to exclude osteochondral free bodies, exfoliative osteochondritis, and other knee joint disorders that may be similar to meniscal tears.

2. MRI is the imaging examination method for diagnosing the positive sensitivity rate and accuracy of meniscus injury to date.

4, how to treat?

Treatment of meniscal injuries includes conservative treatment and surgical treatment. Conservative treatment includes rest, physiotherapy, oral and topical medications, and surgical treatment includes ruptured meniscal dressing, partial resection, total resection, and torn meniscal suture. Surgery is generally performed under arthroscopy with minimal trauma and rapid recovery.

5. Under what circumstances do you need surgery?

The choice of surgical treatment depends mainly on two aspects, one is the severity of the injury, and the other is the impact on the patient's daily life. If you have only mild discomfort and have little impact on your daily life, you can choose conservative treatment. If you have no discomfort when you walk on the road, the up and down stairs are not obvious, but you need to go up and down the stairs frequently in your work and life. It is recommended to perform surgery. If you can't stand the sound of walking or walking soft legs for an indefinite period of time, surgery is recommended. Of course, if the pain makes you struggling, surgery is recommended, and the surgery can also reduce the further tear of the damaged meniscus, giving the damaged articular cartilage a recovery space.
