Lateral meniscus injury self-testing methods mainly include observing whether knee popping, joint pain, mobility problems and other symptoms occur, but can not be diagnosed solely on the basis of symptoms, it is recommended to consult a doctor in a timely manner. If you want to determine whether there is a lateral meniscus injury, you need to know your personal physical condition, if the knee pops when going up and down the stairs, or walking with obvious joint pain, swelling, limited mobility and other symptoms, you need to pay attention to it, and consult a doctor in a timely manner for examination. Physical symptoms alone may not be able to diagnose whether or not a lateral meniscus injury has occurred. X-rays, magnetic resonance imaging (MRI), arthroscopy and other tests are needed to confirm the type of the disease. If a lateral meniscus injury has occurred, conservative treatment or surgical treatment is needed. Conservative treatment mainly involves anti-inflammatory and pain relief, while surgical treatment usually involves arthroscopic surgery.
