SALDIVIA PAREDES, Manuel Alexis  and  YAEGER JARAMILLO, Paz Lourdes. Morphological and biomechanical description of the horse knee. Ces. Med. Vet. Zootec. [online]. 2022, vol.17, n.3, pp.46-64.  Epub Feb 17, 2023. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.7008.

The knee is one of the largest synovial joints in the body and one of the most complex in its morphology and biomechanics. It is constituted by the contact point of bony, cartilaginous, ligamentous, vascular, and muscular structures that, when functioning in an integrated manner, allow granting an extensor, flexor and slight rotation capacity. The equine is characterized by having a patellar locking mechanism known as the reciprocal patellar system, which has the purpose of generating patellar resistance when it is positioned, generating a greater distribution of body weight at the level of the fixed joint, which allows the other pelvic limb to rest in a position of relaxation and semiflexion of the foot. The objective of the following study was to carry out a morphological description of the macroscopic anatomical structures that participate in the conformation of the equine knee joint and how they can allow a particular biomechanical functionality. For this, dissections of eight preserved equine knees were performed and the bone descriptions were of ten knees already worked through osteotechnics in the veterinary anatomy laboratory of the San Sebastián University, headquarters of Patagonia.
