Radiologic examination of the knee, specifically arthrography, involves the use of imaging techniques to visualize the internal structures of the knee joint. This procedure is conducted under radiological supervision, ensuring that the images captured are of high quality and accurately represent the anatomy and any potential abnormalities within the joint. During arthrography, a radiopaque contrast material is injected into the knee joint to enhance the visibility of the joint's internal features on the radiographic images. The process begins with the preparation of the injection site, which includes cleansing the skin and administering a local anesthetic to minimize discomfort. A needle is then carefully inserted into the joint space, allowing for the aspiration of any existing fluid, followed by the injection of the contrast agent. This agent is typically distributed throughout the joint by having the patient perform specific movements, which aids in achieving comprehensive imaging. After the contrast material has been adequately dispersed, radiographic images are taken to provide a detailed view of the knee joint's condition. The procedure concludes with a formal interpretation of the images, which is documented and reported as part of the overall examination. The CPT® Code 73580 is used to represent the entire process, including the radiological supervision and the interpretation of the findings.
