What is this test?
This specialized X-ray captures detailed images of both knees while you are standing and putting weight on them. It includes two views: front-to-back (anteroposterior, or AP) and side (lateral). This method allows doctors to see how your knee joints function under the stress of your body weight, providing crucial information about the condition of bones, cartilage space, and joint alignment.
What is it used for?

• Assessing joint space narrowing, which can indicate arthritis or cartilage loss
• Detecting fractures, bone spurs, or other bony abnormalities
• Evaluating alignment issues such as bow legs or knock knees that affect joint mechanics
• Monitoring progression of osteoarthritis or other degenerative joint diseases

Who should get this test?

• Individuals experiencing persistent knee pain, swelling, or stiffness
• Patients with a history of knee injuries or trauma
• Those suspected of having arthritis or joint degeneration causing functional problems
• People who want to evaluate knee health before surgery or physical therapy

Preparation Required:

• No special preparation is needed.
• Wear comfortable clothing that allows easy access to the knees.

How is the procedure performed?
You will stand upright, bearing your full weight evenly on both legs. The technician will take X-ray images from the front and the side of your knees. This weight-bearing position reveals joint spaces and alignment under natural load conditions, providing a more accurate assessment than lying down.
Risks & Safety:
The test involves a low level of radiation exposure and is generally very safe. The benefit of diagnosing and treating knee problems outweighs the minimal radiation risk.
Results:
A radiologist reviews the images to assess the joint spaces, detect any bone damage, and evaluate knee alignment. These findings guide your doctor in diagnosis and treatment planning.
