Isolated lateral meniscus rupture in dogs: case report

Abstract

Menisci are important intra-articular structures whose main function is attributed to load transmission and impact absorption, reducing biomechanical stress and providing greater osteoarticular stability. In dogs, knee-related disorders are described as the main causes of claudication. This report aims to describe a case of lateral meniscal lesion in a canine without signs of femorotibiopatellar instability, whose main change was claudication. The diagnosis was confirmed through orthopedic evaluation and magnetic resonance imaging, in which an anechogenic line of dissolution of meniscal continuity and intact ligament structures was visualized. As a treatment, the technique of total meniscectomy was chosen, which allowed the recovery of limb function and absence of clinical manifestations.
