Acercamiento a la ruptura del ligamento cruzado craneal (LCCr) en caninos como una de las causas más frecuentes de la claudicación del miembro posterior.

Abstract

The rupture of the cranial cruciate ligament (CCL) is one of the most frequent causes of claudication in dogs, which leads to alterations not only in the stability of the knee joint but also to degenerative changes in the components of the same. It is currently believed that the progression of the disease as well as its chronicity can be overlooked, given the intermittency of the symptoms in the canine. The diagnosis of the primary alteration, as well as the secondary ones, will be based mainly on the orthopedic examination, the use of the radiographic tools of the knee joint and in addition, the attached tests (Arthroscopy, ultrasound and magnetic resonance) that They will provide important information about the structures, membranes and other components of the joint, which may indicate the most probable cause for the development of the rupture of the LCCr. In the last decades, therapeutic alternatives have been proposed for the resolution of the rupture of the LCCr, from conservative protocols (immobilization and pharmacological management) as well as surgical ones (intracapsular, extracapsular and osteotomies of the proximal tibia), without reaching the development of a technique , that avoids the development of pathologies secondary to rupture such as degenerative disease, appearance of osteophytes, hypertrophy of the synovium, osteoarthritis, periarticular fibrosis and lesions in the meniscus.
