X-Ray: Both Knees Lat View

Specimen Required

NONE

Fasting Required

Purpose of the Test

An X-ray of both knees, also known as a bilateral knee X-ray or knee series X-ray, is used to diagnose injuries or conditions affecting the knee joint, such as arthritis, bone fractures, or dislocations. It can also be used to monitor the progression of an existing condition, evaluate the effectiveness of treatment, or to assess the readiness of the knee for surgery.

When this test is required

A healthcare provider may order an X-ray of both knees if a patient is experiencing symptoms such as pain, swelling, stiffness, or limited range of motion in the knees. The test may also be used to diagnose conditions such as osteoarthritis, rheumatoid arthritis, or gout. An X-ray of both knees may also be ordered if the patient has sustained a knee injury, such as a sprain or fracture.

What the Test Detects

An X-ray of both knees, also known as a bilateral knee X-ray or knee series X-ray, is a medical imaging test that uses low levels of radiation to produce images of the bones and other structures of both knees. It can show the alignment and positioning of the bones, as well as any abnormalities, such as fractures, bone spurs, or signs of arthritis.

Preparation for the Test

No special preparation is needed for an X-ray of both knees. However, patients will be asked to remove any jewelry or metal objects that could interfere with the imaging process. Patients may also be asked to wear a hospital gown or loose clothing that does not contain metal fasteners. It is important to inform the healthcare provider if there is a possibility of pregnancy, as radiation exposure can be harmful to a developing fetus.

Sample Requirements

No sample is required for an X-ray of both knees. The test is a non-invasive imaging procedure that uses low levels of radiation to produce images of the knee joint.

Additional Notes

An X-ray of both knees is a non-invasive and generally painless test that is typically completed in a few minutes. However, it does involve exposure to low levels of radiation, so patients should inform their healthcare provider if they are pregnant or suspect they may be pregnant. Patients should also remove any metal objects from the area being imaged and wear a hospital gown or loose clothing that does not contain metal fasteners. The results of the test are usually available within a few days, and the healthcare provider will review the results with the patient and discuss any necessary next steps or treatment options.
