Abordagem cirúrgica à rotura do ligamento cruzado cranial do cão: relato de casos clínicos

Abstract

The present work consisted in the evaluation of two distinct surgical techniques (Lateral suture system and Tibial plateau levelling osteotomy) for the treatment of the cranial cruciate ligament rupture in the dog, by using the description of four clinical study cases. The cranial cruciate ligament rupture is one of the most common orthopedic diseases in dogs. Its clinical panel leads to a series of joint changes that culminate in the lost of function and, consequently, in lower quality of life for the animals. There are several surgical techniques described in the literature that can be applied in the correction of this injury and limit the progression of the changes in the joints affected. Two of these techniques were used in the present work and rely on different principals. One is an extracapsular technique that by using one implant, acquires the ability to mimic the function of the cranial cruciate ligament. The other technique, demands a change on the biomechanics of the stifle joint and is achieved by an osteotomy. This last technique intends to waver the functional need of the ligament turning it redundant. The selection of one or other technique takes in consideration several factors as the high opening of the tibial plateau angle, the animal weigh, the life style of the dog and the financial possibility of the owner. In the clinical cases presented in this work, both techniques showed positive results, although the patients showed different recuperation times after surgery. Factors like hyperactivity, a physical rehabilitation programm or the intervention on both stifles, contributed for the different outcomes or to the chronicity of the primary problem.

O presente trabalho consistiu em avaliar a utilização de duas técnicas cirúrgicas diferentes (Sutura fabelo tibial lateral e Osteotomia de nivelamento da meseta tibial) no tratamento da rotura do ligamento cruzado cranial em cães, mediante a descrição de quatro casos clínico-cirúrgicos. A rotura do ligamento cruzado cranial é uma das doenças ortopédicas de maior prevalência em cães. O seu quadro evolutivo leva a uma série de alterações articulares que culminam num decréscimo acentuado da sua função e consequente diminuição da qualidade de vida dos animais. Existem várias técnicas cirúrgicas para corrigir esta lesão e limitar a evolução das alterações articulares instaladas. As duas técnicas utilizadas no presente trabalho, assentam em diferentes princípios, sendo que uma é extracapsular e através de um implante tem a finalidade de mimetizar a função do ligamento cruzado cranial. A outra técnica, visa através de uma osteotomia, alterar a biomecânica do joelho, tendo como objetivo abdicar da necessidade funcional deste mesmo ligamento tornando-o redundante. A eleição da técnica consiste na ponderação de diferentes fatores como o elevado ângulo da meseta tibial, o peso corporal e estilo de vida do doente, assim como a disponibilidade financeira do tutor. Nos casos clínicos descritos no presente trabalho, ambas as técnicas utilizadas revelaram resultados satisfatórios, ainda que todos os doentes tenham demonstrado um período de recuperação pós-cirúrgico variável. Fatores como hiperatividade, cuidados como reabilitação física e intervenções cirúrgicas a ambos os joelhos, contribuíram para essa variação, assim como a cronicidade da doença.
