SALDIVIA PAREDES, Manuel. Morphological and biomechanical description of the canine knee joint (Canis lupus familiaris). Ces. Med. Vet. Zootec. [online]. 2018, vol.13, n.3, pp.294-307. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.13.3.1.

The synovial joints, or also known as diarthroids, are characterized by their high mobility, constituted by a protective joint capsule, which in turn internally allows the formation of a cavity, where it is possible to observe synovial fluid, responsible for providing Nutritional elements; Purifying cell debris; Make a damping between the articular faces and lubricate the articular surfaces. The knee is one of the largest synovial joints in the body and one of the most complex is its morphology and biomechanics. Its anatomical conformation consists of the union of bony, cartilaginous, ligamentous, vascular and muscular structures that allow to grant a specific functionality in its extensor, flexor and slight rotation capacity. Therefore, the objective of the following study was to perform a morphological description of the macroscopic anatomical structures, which participate in the conformation of the knee joint and how they can allow a particular biomechanical functionality. For this, dissections of 10 knees of male dogs were carried out in the veterinary anatomy laboratory of the Universidad Santo Tomas, Puerto Montt. The results indicate detailed characteristics of the canine knee morphology and how each of them allows to understand and explain the biomechanical capacity of this joint.
