Test Overview An arthrogram is a test using X-rays joint contrast material tendons ligaments cartilage fluoroscopy
An arthrogram is used to check a joint to find out what is causing your symptoms or problem with your joint. An arthrogram may be more useful than a regular X-ray because it shows the surface of soft tissues lining the joint as well as the joint bones. A regular X-ray only shows the bones of the joint. This test can be done on your hip, knee, ankle, shoulder, elbow, wrist, or jaw (temporomandibular joint).
Other tests, such as magnetic resonance imaging (MRI) computed tomography (CT)

How It Is Done
The skin and tissues over the joint will be numbed with medicine. The doctor will put a small needle into your joint. He or she may remove a sample of the joint fluid for testing. Your doctor may use a fluoroscope The doctor will inject a contrast material into your joint. This is usually dye, but it can also be saline, air, or a combination. It helps the doctor see the soft tissues of the joint. Then the doctor removes the needle. You may be asked to be still. Or you may be asked to move your joint. You may also have an MRI or a CT scan to get images of the joint. How long the test takes The test usually takes about 30 to 60 minutes.
Watch How It Feels
You will feel a prick and sting when the anesthetic is given. You may feel tingling, pressure, pain, or fullness in your joint as the dye is put in.
The X-ray table may feel hard and the room may be cool.
You may have some mild pain, tenderness, and swelling in your joint after the test. Ice packs and non-prescription pain relievers, used as the package directs, may help you feel more comfortable. You may also hear a grating, clicking, or cracking sound when you move your joint. This is normal and goes away in about 24 hours. If you have ongoing pain, tenderness, or swelling of the joint, tell your doctor.
Risks
You can have a few problems from an arthrogram, such as:
Joint pain for more than 1 or 2 days. An allergic reaction to the dye. Damage to the structures inside your joint or bleeding in the joint. But this is very rare because the needle that is used is small. Infection in the joint. There is always a slight risk of damage to cells or tissue from being exposed to any radiation, including the low levels of radiation used for this test. But the risk of damage from the X-rays is usually very low compared with the potential benefits of the test.
