A five-year retrospective study of dogs with patellar luxation was performed. A total of 75 dogs (n=122limbs) were studied: 82.7% (n=62) had medial luxation, 14.6% (n=11) had lateral luxation, and 2.7%(n=2) had both luxations in same stifle joint. Considering the dogs with medial patellar luxation, 6.7%(n=5) were mixed-breed and 76% (n=57) were purebred, with high prevalence in Poodles (n=27; 35.6%),Pinschers (n=13; 17.3%), and Yorkshires (n=4; 5.3%). Of the dogs with lateral patellar luxation, one(1.3%) was mixed-breed and 13.3% were purebred, with high prevalence in Poodles (n=6; 8%) andPinschers (n=2; 2.7%). Regarding the 62 dogs with medial patellar luxation, 20 were unilateral and 42bilateral. Of the 11 dogs with lateral patellar luxation, five were unilateral and six bilateral. Statistically,females were more affected than males by both medial and lateral patellar luxations. The grade II (25;33.3%) of patellar luxation was the most often in medial luxation followed by grades III (20; 26.7%), IV(11; 14.7%), and I (16; 7.9%). The grade II (5; 6.7%) was the most often in lateral luxation followed bygrade I (4; 5.3%), and simultaneously grades III (1.3%) and IV (1.3%). The surgical treatment wasperformed in 64 dogs and the others were submitted a conservative management. It was possible toconclude that among the dogs with patellar luxation evaluated in this study, the most affected were toyand miniature breeds and female dogs with medial patellar luxation.(AU)
