For the vast majority of people, reading MRI films of the knee is very difficult. If patients do want to understand and learn, they can take the following approach: 1. They can start with the MRI report. This type of imaging report is the final conclusion of a careful analysis of all the findings by the relevant technologist, and the patient can search for each conclusion on the report and then clarify its clinical significance.2. The patient can ask the relevant imaging physician, or orthopedic surgeon, to interpret the patient’s MRI plain film and understand its clinical significance, which is the quickest and most convenient way.3. If the patient wants to go deeper, then he or she must learn the basics of the knee joint. It is recommended that the patient learn the systemic anatomy involving the knee motor system and also learn the local anatomy of the knee joint. After this, the patient also needs to clarify the relevant knee structures on the MRI plain film and the relevant imaging manifestations of their abnormalities against the section on imaging MRI. Finally, it is recommended that patients go to a professional institution and have such reports and plain films interpreted by a professional physician so that the deviations will be smaller and more efficient.
