Notes on musculoskeletal ultrasound examination include: 1. Doctors need to be familiar with human anatomy and undergo professional training before they can be inducted, and the operation cannot be violent to avoid aggravating the patient’s discomfort and pain. 2. Patients should be relaxed before the examination, should not be too nervous, believe in the doctor’s professionalism, and just actively cooperate with the doctor during the examination. Ultrasound examination is real-time, that is, during the examination, any problems arise, the doctor can promptly communicate with the patient, such as when the structure cannot be clearly observed, the patient can be asked to turn sideways or bend the knee, in order to achieve a better examination effect.
