Walking fine with a meniscus injury means that the symptoms of the injury are not obvious, but not all injuries with mild symptoms are not serious. Further examination is needed to determine whether there is anything wrong or not. The severity of symptoms after meniscus injury can reflect the severity of the injury to a certain extent, but it is not necessarily 100% accurate, so it is still necessary to carry out tests before accurately diagnosing whether there is anything wrong or not. The test is an MRI of the knee joint. If the injury is mild, it can be treated conservatively. The main way is to limit the movement of the knee joint, and painkillers (e.g. Celecoxib) can be used symptomatically. However, the use of medication should be under the supervision of a doctor. If the damage is serious, surgery can also be performed, which is mainly minimally invasive arthroscopic knee surgery. It is recommended that the patient should seek medical treatment by a professional doctor in time.
