Computed Tomography (CT) of the Stifle 147(A)(B)Figure 20.10 (A) Radiographs of a 5-month-old Golden Retriever with an avulsion of the attachment of the cranial
cruciate ligament. On the caudo-cranial view subchondral sclerosis in the area of the medial part of the lateral femoral
condyle can be appreciated (black arrowheads). (B) Corresponding transversal CT image, and sagittal and dorsal
reconstructed images showing clearly the avulsed proximal attachment of the cranial cruciate ligament at the medial part
of the lateral condyle with associated subchondral sclerosis (black arrowheads).
(Vande Berget al. 2002). CT is useful in detect-
ing avulsions of the different intra-articular
structures including the CrCL, the CaCL, the
m. extensor digitorum longus, and the m.
popliteus. The detection of a bony avulsion
fragment is superior with CT, compared with
other types of imaging. CTA helps in eval-
uating the status of these fragments. Plain
CT images are not very useful in evaluating
the integrity of the cruciate ligaments and
