Canine models of anterior cruciate ligament
reconstruction are commonly used to compare different
reconstruction techniques, with the posterior horn of
the medial meniscus as a common site of injury resulting
from knee instability. This study performed T2* regional
mapping of the canine knee meniscus in 5 control
subjects. The regions of interest (ROIs) were the
anterior and posterior horns of the medial and lateral
menisci. The results indicated prolonged T2* values in
the posterior horn of the medial meniscus as compared to
the remaining ROIs. The results provide a baseline of
normative values for researchers in future preclinical
studies.
