PEREZ, D. M.; MARTINEZ, M. M.  and  CARDONA, J. A.. Advance of tibial tuberosity with bone heteroimplant for previous crossed ligament in canine. Rev. Med. Vet. Zoot. [online]. 2021, vol.68, n.1, pp.19-36.  Epub Nov 21, 2021. ISSN 0120-2952.  https://doi.org/10.15446/rfmvz.v68n1.97249.

The clinical and radiological evaluations are techniques used for the diagnosis of the anterior cruciate ligament rupture (LCAR) and the post-operatory assessment of corrective surgeries. It was proposed as an objective to describe the post-operatory results of the advance technique of tibial tuberosity in canines with LCAR using bovine bone conserved in 98% glycerin. Five canines were intervened and with no other radiological changed in the related bone columns. The bone heteroimplant was cut in a wedge-like manner and for its size it was taken into account the pre-operatory measurement that the knee needed to reach the advancement angle of the tibial crest. Next, the bone implant was fixated to the local receptor with metallic implants (Kirschner needles and orthopedic wire). In the post-op, the canines were evaluated for 90 days for clinical signs such as claudication, pain when flexing and extending and inflammation according to the knee circumference, and for 120 days the advancement angle of the tibia and the radiopacitry of the heteroimplant in relation to the surrounding bone. The trial established that the clinical and radiological parameters have a statistically significant effect; however, the evaluation of the tibial advancement angle does not have a significant effect between the patient and the post-operatory days. During the evaluation period, the heteroimplant bovine bone proved to be effective to stabilize the knee in canines with LCAR.
