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.

Isolated medial meniscal tear in a domestic shorthaired cat

“…OCD is rarely reported in conjunction with meniscal damage in cats 2 . Meniscal tears in cats have been reported to occur concurrently to the above‐described pathologies, and also alongside patellar luxation 8 . To the authors’ knowledge, an isolated meniscal tear has not yet been reported in cats.…”

“…The condition has been rarely reported in dogs. 8,9 The menisci are two semilunar fibrocartilaginous structures between the articular surfaces of femur and tibia. 10,11 They contribute to joint congruence, are part of load transmission and impact absorption processes, reduce biomechanical stress and contribute towards stifle stability.…”
