General treatment: if the patient’s right knee cruciate ligament is only damaged and not ruptured, the acute injury can be iced, and can be properly pressurized with a bandage, and the patient should also pay attention to rest and elevate the affected limb appropriately. 2. Drug treatment: if the right knee anterior cruciate ligament injury is mild, you can take non-steroidal anti-inflammatory drugs, such as ibuprofen for anti-inflammatory pain, if the patient has a localized infection, you also need to take drugs such as cefuroxime for anti-infection treatment. 3.
