Why is an X-Ray Right Knee AP Performed?
An X-ray right knee AP is typically performed to evaluate the following:
1] Fractures or Bone Injuries: An X-ray can reveal fractures in the femur, tibia, fibula, or patella. It can also detect any displaced bone fragments that might require surgical intervention.
2] Arthritis: One of the most common uses of knee X-rays is to diagnose arthritis. The AP view can reveal signs of osteoarthritis, such as joint space narrowing, bone spurs (osteophytes), and changes in the bone structure.
3] Knee Deformities: The X-ray can help identify deformities in the knee, such as bowing or knock-knee (genu varum or genu valgum), which may indicate underlying conditions that need to be addressed.
4] Knee Alignment: The X-ray can evaluate the alignment of the bones, particularly how the femur, tibia, and patella interact. Misalignment of the knee joint can lead to pain and further complications.
5] Infections or Tumors: Although X-rays are typically used to examine bones, they can sometimes reveal abnormal growths, bone infections, or cysts that might not be immediately visible through a physical exam.
6] Joint Effusion: An X-ray can also provide clues to the presence of excess fluid in the knee joint, which could indicate inflammation, infection, or other underlying issues.
How is the X-Ray Right Knee AP Performed?
1] Positioning: The patient is typically asked to lie down or sit on the examination table with their leg extended. The knee should be fully straightened with the foot pointing straight ahead. The X-ray technician will position the X-ray machine directly in front of the knee joint to capture the front-to-back image.
2] Image Capture: The technician will then instruct the patient to remain still while the X-ray machine takes the image. The patient may be asked to hold their breath briefly to avoid motion blur during the image capture. In some cases, the technician might take multiple images at different angles to get a more complete picture of the knee.
3] Review: After the X-ray is completed, the images are sent to a radiologist for review. A report is generated, which will be sent to the referring doctor, who will then discuss the findings with the patient.
