CT Scan Knee Pain

There are many different tools available to help medical professionals diagnose and treat a wide range of conditions. Historically, x-ray assessment has been the traditional initial assessment of knee pain, with a CT scan essentially being a three dimensional version of x-ray imaging and therefore reserved for instances where more detailed imaging assessment is required.

Knee pain CT scans are painless, accurate and non-invasive.


  • If you require a CT Scan for knee injuries, you will not have any preparation to do for your appointment.
  • You will be asked to lie back on a flat bed that will pass into the scanner, which is a ring that rotates around your knee as it passes through it. You must stay still and breathe normally. The sensation of claustrophobia is minimise as the scanner never surrounds your whole body at once and you will be able to see both ends of it.
  • The entire procedure usually only lasts for several minutes on the scan table.
  • A radiologist, a medical doctor specialised in interpreting medical images for the purposes of providing a diagnosis, will then review the images and provide a formal written report.

Case examples:

1. Anterior cruciate ligament (ACL) tear

MRI of the knee demonstrates a full thickness tear of the anterior cruciate ligament (ACL). The ligament is typically taught, unlike this case (arrows).

2. Meniscus injury

MRI of the knee confirms the presence of a large tear of the lateral meniscus (arrow). Compare the appearance of the torn meniscus with the normal medial meniscus (circled) which is triangular and hypointense (dark).

3. Use of CT to identify bone lesions

CT can be used to assess focal bone lesions, such as in this case where two cortical desmoids (arrows) are noted. Cortical desmoids are an incidental finding and require no further follow up.
