Abstract

This study was performed in 41 dogs with unilateral or bilateral medial patella luxation (MPL) and/or cranial cruciate ligament rupture (CCLR). These dogs were classified into 4 groups according to MPL grading system. Radiographic evaluation was performed for pelvis and stifle joint in the dogs. Norberg, inclination, quadriceps and femoral varus angle were measured and analyzed with MPL grading and the existence of cranial cruciate ligament rupture. The Norberg and inclination angle showed no differences between 4 grading groups and between CCLR and no CCLR groups. However, quadriceps and femoral varus angle were statistically different between grade 1, 2 and grade 3, 4 groups. They also have shown the statistical difference between CCLR and no CCLR group. Further studies for how these parameters affect the prognosis and the results of surgical treatment of MPL should be needed.
