How do you do a lateral knee injection?
Procedure Description
- The patient is supine on the table with the knee extended (some physicians prefer that the knee be bent to 90 degrees).
- The superior lateral aspect of the patella is palpated.
- The skin is washed with povidone-iodine solution.
- The needle is inserted through stretched skin.
How long does an MR arthrogram take?
The arthrogram itself usually takes about 15 minutes. You may then have to wait a short time before having the scan performed. A subsequent MRI scan may take 30-45 minutes, depending on the joint and the number of scans that have to be done.
How is an arthrogram performed?
In arthrography, a long, thin needle is used to put contrast dye right into the joint and a series of X-rays is taken with the joint in various positions. X-rays use small amounts of radiation to get pictures of the inside of the body.
What is the difference between arthrography and arthroscopy?
Whereas the arthrogram reproduces a black-and-white, two-dimensional picture of a spatial structure (an indirect procedure), arthroscopy provides a colored picture facilitating a three-dimensional assessment of the joint cavity, palpation, and the arthroscopic operation.
Is knee arthrogram painful?
While the arthrography procedure itself causes no pain, having to move or hold the joint still in certain positions might cause some discomfort or pain, particularly if you’ve recently had surgery or a joint injury.
Can you exercise after arthrogram?
You will be able to leave soon after the arthrogram is finished. After the arthrogram your joint and where you had the injection may be a little sore, but this usually goes away within a day. If your joint is sore, do not lift or do any heavy exercise for one to two days after the arthrogram.
What is best approach for knee injection?
The best approach to a knee injection is the path of least obstruction and maximal access to the synovial cavity, which could be superolateral, superomedial, or anteromedial/anterolateral. Plain radiography is recommended for better assessment of the bony anatomy of the individual knee joint.
Do they sedate you for an arthrogram?
If you will be undergoing a CT or MRI arthrogram and tend to experience claustrophobia or anxiety, let your radiologist know. You may be a good candidate to receive sedative medication prior to the procedure to put you at ease.
Who performs arthrogram?
Either a nurse or a radiographer (medical imaging technologist) may assist the radiologist in the arthrogram. The radiographer is responsible for taking the images in the arthrogram and the subsequent CT or MRI under the radiologist’s direction.
What dye is used in arthrogram?
That’s when you might need an arthrogram, also called arthrography. It’s another type of imaging where first you get a special dye, called contrast dye, injected into your joint.
Why does an arthrogram hurt?
Is it normal to have pain after arthrogram?
Mild pain is most pronounced 4 hours after MR arthrography and disappears within 1 week after MR arthrography. Pain is more pronounced in patients younger than 30 years than in patients older than 30 years (P < . 043). There is no significant relationship between pain score and radiologist experience.
Can you shower after arthrogram?
Take any prescribed medicine (including pain medicine) as directed. Bandages were placed over the injection site after the procedure. It is important to keep the site clean and dry. You may take a shower or bath while the bandage is on.
