73560 Radiologic examination, knee; 1 or 2 views

Name of the Procedure:

Radiologic Examination, Knee; 1 or 2 Views Common Names: Knee X-ray, Radiography of the Knee

Summary

A knee radiologic examination is a simple imaging procedure that uses X-rays to take pictures of one or two views of your knee. This helps doctors visualize the bones and joints within your knee to diagnose issues or monitor conditions.

Purpose

This procedure is typically used to assess knee pain, swelling, injuries, or deformities. The goal is to diagnose fractures, arthritis, infections, and other knee problems accurately.

Indications

• Persistent or severe knee pain
• Swelling in the knee joint
• Recent knee trauma or injury
• Suspected fractures or dislocations
• Evaluation for arthritis or degenerative joint disease
• Monitoring of known knee conditions

Preparation

• No special preparation is required for a knee X-ray.
• You may be asked to remove any metal objects, such as jewelry, that can interfere with the imaging.
• Inform your doctor or technician if you are pregnant.

Procedure Description

1. You will be positioned either lying down or standing, depending on which view(s) are needed.
2. You might need to change positions to capture different views, typically front (anterior-posterior) and side (lateral) views.
3. A protective lead apron may be placed over parts of your body not being imaged to protect you from radiation.
4. The X-ray machine will then be positioned over your knee, and the technician will take the images.

Duration

The entire procedure typically takes about 10-15 minutes, including the time needed to position you and take the necessary images.

Setting

Knee X-rays are usually performed in a hospital radiology department, an outpatient clinic, or a specialized imaging center.

Personnel

• Radiologic Technologist (performs the X-ray and positions you for imaging)
• Radiologist (interprets the X-ray results)
• Referring Physician (orders the X-ray and discusses the results with you)

Risks and Complications

• Exposure to a small amount of radiation (risks are minimal and benefits outweigh them in clinical decision-making)
• Rarely, allergic reactions to any materials used during the procedure (like contrast agents, though not typically used in simple X-rays)

Benefits

• Quick and non-invasive diagnostic tool
• Helps in the accurate diagnosis of various knee conditions
• Immediate results in emergency situations

Recovery

• No specific recovery time; you can resume normal activities immediately after the X-ray.
• Follow any additional instructions provided by your doctor based on the findings.

Alternatives

• MRI or CT scan can provide more detailed imaging but are more expensive and time-consuming.
• Ultrasound can be used for soft tissue evaluation but is less effective for visualizing bone.

Patient Experience

• The procedure is generally painless.
• You might feel slight discomfort while positioning the knee.
• No anesthesia or sedation is required, and you can manage any minor discomfort with standard pain relief methods if necessary.
