Abstract

Patellar luxation is one of the main affections of the canine femoro-tibial-patellar joint. Thepathophysiology is complex and not completely understood. The most commonly performed surgicalprocedures are femoral trochleoplasty, femoral corrective osteotomies and tibial tuberosity transposition,which can be performed in two ways: tibial tuberosity transposition (3T) and tibial tuberosity transpositiontool (4T). Complications inherent to the aforementioned surgeries are well described in the literature,however, as it is a procedure that is not routinely performed, reports of complications regarding the 4Ttechnique are rarely reported. The present project has the objective of demonstrating the use of a newspecific implant to transpose the tibial crest through a new technique, simpler in terms of application,having precision of how much it will be translocated and with more possibility of success. performedusing an N of 20 dog cadavers. They will be divided into 3 groups, as follows: group "A" will use the 3Ttechnique; group "B" the 4T technique and group "C" will be made the new technique. After performingthe techniques, X-rays will be performed using craniocaudal and mediolateral projections to evaluate thedisplacement of the tibial crest. In addition, an evaluation between the groups will be made, comparing:the execution time of each technique; if the translation of the tibial crest was achieved as planned, thecomplications observed in each group will also be reported individually. It is expected that the newthreaded device will provide a better and more accurate transposition of the tibial tuberosity with thesurgical time and reduced trans and postoperative complications, resulting in an earlier return to limbfunction and, therefore, an improvement in quality of life and animal welfare.
