Objective— To determine the clinical usefulness of ultrasonography for diagnosis of meniscal pathology in dogs. Study Design— Double‐blind prospective study. Animals— Dogs (n=10) with lameness localized to the stifle. Materials and Methods— Sonographic examination of each affected stifle was performed by 1 ultrasonographer unaware of specific historical and clinical data for the dog. Sonographic findings were recorded, but not reviewed until study completion. Arthroscopic examination of the affected stifle was performed within 48 hours of ultrasonography by 1 surgeon unaware of ultrasonographic findings. Arthroscopic findings were recorded, but not reviewed until study completion. Two investigators compared the ultrasonographic and arthroscopic findings at study completion to determine the sensitivity, specificity, positive predictive value, and negative predictive value. Results— Two of the 10 dogs had bilateral stifle evaluation. Twenty‐four lateral and medial menisci, with normal and abnormal findings, were examined. The sensitivity and specificity for ultrasonographic diagnosis were 90.0% and 92.9%, respectively; positive and negative predictive values were 90.0% and 92.9%, respectively. Conclusions— Ultrasonography is highly specific and sensitive for diagnosing bucket handle tears of the medial meniscus in dogs. Clinical Relevance— Ultrasonographic evaluation of menisci in dogs is a noninvasive method for accurately and efficiently diagnosing pathology, determining the need for surgical intervention, and providing comprehensive information to clients.
