Computed Tomography
Foal 2: Plain computed tomography (CT) of the L stifle revealed marked
effusion of the LFTJ with irregularity of the subchondral bone of the
lateral femoral condyle (LFC) and the lateral tibial condyle (Figure 1
d). Contrast arthrogram revealed disruption of the LM caudally, with
lateral displacement (Figure 1 e). Disruption of the meniscofemoral
ligament was present at its attachment to the caudal horn of the LM
(Figure 1 f). The cranial lateral meniscotibial ligament (MTL) was also
irregular in appearance.
Foal 3: Marked effusion was present within all three compartments of the
R stifle. The proximal, lateral articular margin of the tibia was mildly
irregular. The LM was diffusely abnormal with several tears in multiple
orientations within the lateral and caudal aspects (Figure 3 b). A
large, pyramidal shaped tear of the axial aspect of the caudal horn of
the LM was present (Figure 3 c). The caudal lateral MTL was not clearly
identified and a central region of hypoattenuation was present in the
cranial lateral MTL (Figure 3 d).
