The objective of this article was to study the measures and the anatomic relationships of the trochlear groove and patella in radiographic examinations of healthy dogs predisposed to medial patellar dislocation breeds, analyzing and comparing with the trochlear groove and patellar of patients with such disease. 40 knees of predisposed pure breeds dogs were used which were divided into two groups: group 1 (G1) consisting of 18 knees that do not show patellar dislocation and group 2 (G2) consisting of 22 knees showing patella in the medial grade II or III. Depth and width trochlear groove, height and thickness of the patella, a percentage of the patella in the groove, groove angle troclear were measured and calculated the ratios of patellar width and trochlear groove and depth of the trochlear groove and thickness of the patella. All parameters studied showed statistically significant differences, in comparison between healthy and affected dogs, compared to being evaluated by Student's t test. Through evaluation and measurements on radiographs G1 dogs, it were developed predictor formulas of broadening (Lsd = Lpp/0,89 – Lsp) and deepening (Psd = 0,65Ep –Psp) required the trochlear groove to perform trochleoplasty block. / Luxação medial da patela é uma afecção comum em cães de pequeno porte, devendo ser diagnosticada e tratada o mais cedo possível com objetivo de evitar maiores deformações e alterações articulares secundárias. O objetivo deste trabalho foi estudar as medidas e as relações anatômicas do sulco troclear e da patela através de exames radiográficos de cães sadios de raças predispostas à luxação patelar medial, analisando e comparando com o sulco troclear e patela de pacientes portadores desta enfermidade. Foram utilizados 40 joelhos de cães de raças predispostas que foram divididos em dois grupos, sendo o grupo 1 (G1) composto de 18 joelhos que não apresentavam luxação de patela e o grupo 2 (G2) composto de 22 joelhos que apresentem luxação de patela medial em graus II ou III. Foram realizadas mensurações de profundidade e largura do sulco troclear, altura e espessura da patela, percentual da patela dentro do sulco, ângulo do sulco troclear, sendo calculadas as razões entre largura patelar e do sulco troclear e profundidade do sulco troclear e espessura da patela. Todos os parâmetros estudados demonstraram diferença estatística significativa, na comparação entre cães sadios e portadores da afecção, ao serem avaliadas pelo teste t de Student. Através dessas medições realizadas nas radiografias dos cães do G1 foram desenvolvidas fórmulas preditivas do alargamento (Lsd = Lpp/0,89 – Lsp) e aprofundamento (Psd = 0,65Ep –Psp) do sulco troclear, para realização de trocleoplastia em bloco.
