The purpose of the present study was to evaluate the long-term clinical and radiographic aspects of the knees of dogs submitted to the modified tibial tuberosity advancement technique (TTAm). Gait analysis, physical evaluation, radiographic examination, goniometry of the knee, thigh circumference of girth and leg of the patients and questionnaire to owners were performed, approximately five years post-operatively. Current radiographic examinations were compared to those taken prior to surgery and 120 days postoperatively. Physical examination revealed that most animals presented positive response to cranial drawer and tibial compression tests on the operated knees and negative in the contralateral limb. In reviews of goniometry and perimetry significant differences between the operated and contralateral knee were observed showing decrease in operated knees compared to control for goniometry and thigh circumference, and increase in leg circumference. Regarding radiographic assessment, progression in most osteoarthritis parameters was observed, especially in the moments early postoperatively and five years postoperatively. Considering the gait analyses, most animals presented some degree of lameness, in contrast to the owners' assessment, which indicated most animals not showing lameness. In conclusion, osteoarthritis progresses with the time even after TTAm surgery in cases of cranial cruciate ligament rupture (CCRL). The thigh and leg circumference and knee goniometry values did not return to the normal biometry in comparison to the contralateral non-affected limb values following five years of TTAm surgery. However, the owners were satisfied with the recovery of the animals and would be willing to accept TTAm indication for the same dog or for another one bearing CCRL. Different methodologies of scales have been used for both gait and osteoarthritis assessment in several papers, which impaired comparison with the results of the ...
