RESUMO

Ligamentary lesions are probaly the most comum cause of hind limb lamness and the degenerative disease of the knee joint seem in dogs. The biomechanical function of the knee joint in dogs was made, comparing the cranial translation degree and articular stiffness of the tibia in relation to the femur, in normal joints, joints with rupture of cranial crucial ligament and cirurgicaly repared. Mechanical assays was realized by Kratos 5002 machine, and recorded in real time the parameters of force (N) and translation/deformation, in mm. The assay had consisted in to use a force(N) registering the cranial translation. To the normal knee, the deslocation media founded after 3 repetitions was 3,39 ; 3,47; 3,53. To the knee with surgical section was 12,96; 13,24; 13,34. To the repared knee was 4,05; 4,61; 4,42These study allows to conclude that the cranial translation is added in four times and the articular stiffness is reduced one and a half times when statistically compared. The statistical analysis reveled significant diference between groups to the cranial tranlation e articular stiffness (p<0,05). To the repared knee the cranial translation don?t reveled significant diference but the articular stiffiness seens anormal.
