Abstract

Ultrasonography is reported to be accurate in diagnosing meniscus injuries in dogs but the effect of transducer type has not been studied. The aim was to determine the effect of ultrasound transducer type on utility of meniscal ultrasound. We hypothesized that ultrasonography will provide good diagnostic utility for meniscal injury and that linear transducers will perform best. In this prospective study, the ultrasonographic findings of the medial meniscus using three transducers were compared to arthrotomy findings. Thirty-nine stifles were included with an injury prevalence of 23/39 (59%). The standard linear transducer provided the highest negative predictive value (60%). The small footprint linear transducer provided the highest positive predictive value (76%). Higher frequency, linear transducers outperform microconvex transducers in diagnosis of medial meniscal injuries. However, sonographic assessment of medial menisci may be less accurate than previously reported. Caution should be used when using ultrasound to guide treatment options for meniscus injuries.
