Name of the Procedure:

Radiologic Examination, Knee; Complete, 4 or More Views

• Common Name(s): Knee X-ray
• Technical Term: Radiographic Examination of the Knee

Summary

A knee X-ray is a diagnostic imaging procedure that uses X-ray technology to capture detailed images of the knee joint from multiple angles. This complete examination typically involves taking four or more views to assess the bones, joints, and surrounding tissues.

Purpose

• Medical Conditions Addressed: Knee pain, injury, arthritis, fractures, dislocations, and degenerative joint diseases.
• Goals/Outcomes: To diagnose the underlying cause of knee problems, guide treatment plans, and monitor the progression of a disease or recovery post-injury or surgery.

Indications

• Persistent knee pain or swelling
• Reduced range of motion in the knee
• Suspected fracture or dislocation
• Chronic conditions such as arthritis
• Post-operative evaluation
• Traumatic injury to the knee

Preparation

• Patient Instructions: No special preparation is usually needed for a knee X-ray. Patients may be asked to remove any metal objects and change into a hospital gown.
• Pre-Procedure Assessments: A brief medical history and list of current medications may be reviewed.

Procedure Description

1. The patient is positioned on the X-ray table. Positions may include lying down, standing, or sitting, depending on the views required.
2. Protective shielding is applied to cover parts of the body not being imaged.
3. A radiologic technologist positions the knee and adjusts the X-ray machine.
4. Multiple images are taken from different angles (e.g., front, side, and oblique views) to ensure a comprehensive examination.
5. The technologist might ask the patient to change positions between images.

• Tools/Equipment Used: X-ray machine, protective lead shielding.
• Anesthesia/Sedation: Not required for this procedure.

Duration

The entire procedure typically takes about 15 to 30 minutes.

Setting

Performed in a radiology department of a hospital, outpatient clinic, or specialized imaging center.

Personnel

• Radiologic Technologist: Performs the X-ray imaging.
• Radiologist: Reviews and interprets the X-ray images.
• Referring Physician: Orders the X-ray and discusses the results with the patient.

Risks and Complications

• Common Risks: Minimal exposure to radiation.
• Rare Risks: Allergic reaction if contrast media is used (very uncommon for a knee X-ray).
• Most risks are managed by using the lowest effective radiation dose.

Benefits

• Expected Benefits: Accurate diagnosis of knee conditions, guiding appropriate treatment plans, monitoring disease progression or recovery from injury.
• Benefit Realization: Immediate acquisition of images, with results often available within hours to days.

Recovery

• Post-Procedure Care: No specific care needed post-X-ray.
• Recovery Time: Immediate return to normal activities.
• Follow-Up: Based on the findings, follow-up appointments may be scheduled to discuss results and next steps.

Alternatives

• Alternative Options: MRI, CT scan, ultrasound, physical examination.
• Pros and Cons:
  • MRI: More detailed images of soft tissues, but more expensive and time-consuming.
  • CT Scan: More detailed bone images but higher radiation dose.
  • Ultrasound: No radiation, but less detail for bone structures.
  • Physical Examination: No imaging but can assess functional status.

Patient Experience

The patient might feel slight discomfort from holding still or changing positions during the procedure. However, no pain is involved in the X-ray itself. Comfort measures include clear instructions and supportive positioning by the technologist.
