Name of the Procedure:

Radiologic Examination, Knee; 3 Views
Common Name(s): Knee X-ray, Knee Radiograph

Summary

A radiologic examination of the knee involves taking X-ray images of the knee joint from three different angles. This helps doctors visualize the bones, cartilage, and other structures within the knee to diagnose injuries or conditions.

Purpose

Medical Condition or Problem:

• Injuries (fractures, dislocations)
• Arthritis
• Infections
• Bone tumors

Goals or Expected Outcomes:

• Accurate diagnosis of knee conditions
• Determination of appropriate treatment strategies

Indications

Symptoms or Conditions:

• Knee pain
• Swelling or inflammation
• Decreased range of motion
• History of knee trauma ##### Patient Criteria:
• Patients exhibiting the above symptoms
• Monitoring the progression of diagnosed knee conditions

Preparation

• No fasting or medication adjustments necessary
• Inform the technician if you are pregnant
• Wear comfortable clothing and remove any metal objects

Procedure Description

1. The patient will be asked to stand or lie down in different positions to capture three distinct views of the knee.
2. A radiologic technologist will position the X-ray machine and place lead shielding over other parts of the body to minimize radiation exposure.
3. The technologist will take the X-rays, asking the patient to remain still to ensure clear images.
4. The images are then processed and reviewed by a radiologist.

Tools, Equipment, or Technology:

• X-ray machine
• Protective lead shielding

Anesthesia or Sedation:

• Not required

Duration

• The entire process typically takes about 15 to 30 minutes.

Setting

• Performed in a hospital radiology department or an outpatient imaging center.

Personnel

• Radiologic Technologist
• Radiologist (for image interpretation)

Risks and Complications

Common Risks:

• Low-level radiation exposure

Rare Complications:

• Misdiagnosis due to unclear images, managed by retaking the X-rays

Benefits

• Accurate diagnosis of knee problems
• Quick and non-invasive procedure
• Immediate preliminary results

Recovery

• No recovery time needed
• Resume normal activities immediately
• Follow up with your doctor for results and further treatment

Alternatives

Other Treatment Options:

• MRI: More detailed images; better for soft tissues.
• CT Scan: Detailed cross-sectional images; higher radiation dose. ##### Pros and Cons:
• MRI and CT scans are more expensive and time-consuming but provide more detail than X-rays.

Patient Experience

• You might feel brief discomfort holding certain positions.
• No pain involved in the imaging process.
• Comfort measures include explaining each step and providing support during positioning.
