Shoulder and knee pain can have many different causes. If you have experienced an injury or are having unexplained joint pain, your doctor might order an arthrogram to help diagnose the cause of your discomfort.
How an Arthrogram Works
An arthrogram is a medical imaging method that provides your doctor with a detailed view of the inside of your joint. It differs from other imaging procedures because it uses a series of pictures, rather than a single image. This helps the doctor identify injuries or other changes in bones, as well as in other joint structures, including muscles, tendons, ligaments, and cartilage.
Radiologists create arthrograms by using X-rays, MRI images, or CT scans. They also use contrast dye to highlight the area in the images. Knee and shoulder arthrograms are the most common, but this type of imaging can also be used for other joints, such as the hip, ankle or elbow.
What Happens During an Arthrogram?
At your appointment, the technologist will position you on the table and conduct the imaging exam. The radiologist will administer the contrast agent. Your position varies depending on whether you are getting an X-ray, CT scan or MRI arthrogram. Sometimes, regular X-rays are taken in advance to help guide the contrast dye injection and capture baseline imaging for comparison.
After the radiologist removes the needle, they will ask you to move your shoulder or knee joint to help spread the contrast material throughout the area. Depending on the type of arthrogram you have, the process takes anywhere from 30 minutes to an hour for an MRI arthrogram.
After the Arthrogram
After your appointment, you probably won’t need to plan much recovery time. However, you may experience some discomfort after your shoulder or knee arthrogram, including swelling and joint pain. You may apply ice or take an over-the-counter analgesic to help with pain. These symptoms usually resolve within 48 hours.
There is a slight risk of joint dislocation after an arthrogram. Your radiologist may recommend avoiding strenuous activity for 24 hours to give your body time to release the injected fluid from the joint.
