Resumo: | The current study compared three different methods to perform the tibial tuberosity transposition technique (TTT) in patients with medial patellar luxation observing the luxation degree, lameness degree, the surgery time, articular amplitude and trans-operative and postoperative complications. 19 dogs from the surgical routine were selected and randomly divided in three groups. Patients in group “A” (n=7) were submitted to the tibial tuberosity fixation with two 1,2mm K- wire. In group “B” (n=9) the animals were submitted to fixation of osteotomized tuberosity with a 2mm cortical screw and the dogs in group “C” (n=7) were submitted to the cerclage by n°2 steel surgical wire technique. The sample number had 23 transpositions and the same researcher carried out the surgical procedures and evaluations until 90 days after the interventions. The luxation degree in the operated limbs was bigger in “C” keeping the trend and the residual luxation presented a higher frequency in this group. The initial lameness scoring was bigger in groups “C” and “A” in comparison to group “B”; however, on day 10, the scores were bigger in “A” than in “C” and “B” had an intermediate score. Surgical time was different among the groups, lasting 13min46sec more to the animals in “C” in comparison to “B”. Joint amplitude in the groups was not influenced by the evaluation days where the means oscillated between 138,76°± 2,32°, though the patients in “C” had a bigger amplitude regarding the others. The three techniques presented similar results considering the evaluated parameters, except for the residual luxation on the 90 day where “C”> “B”> “A”, and no bigger complications happened to justify a new surgical intervention. |
