Medial patellar dislocation is a common condition in small dogs and should be diagnosed and treated as early as possible in order to prevent further deformities and secondary osteoarthritis. 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.
