Plain-English summary
A study found that patellar luxation, a condition where the kneecap slips out of place, was diagnosed in 559 dogs in Italy, with mixed breed dogs being the most affected. Most cases involved medial luxation, where the kneecap moves inward, and about half of the affected dogs were female. After treatment, 88% of the dogs had a good outcome, although some experienced minor or major complications, including a recurrence of the luxation. This suggests that while surgery can be effective, there are risks involved, especially in certain breeds.

Abstract
OBJECTIVE: To determine the prevalence of patellar luxation in dogs in Italy and its relation to signalment, the frequency and the type of postoperative complications and the outcome of treatment, and to compare the findings with those of other studies. MATERIALS AND METHODS: The medical records from four referral clinics were searched for dogs with orthopaedic disorders referred from 2009 to 2014. From these data, the records of dogs with patellar luxation were identified, and the signalment, age and body weight, grade, side and direction of patellar luxation, treatment, postoperative complications, and outcome were retrieved. Univariate and multivariate statistical analyses were used to evaluate the data. RESULTS: Of 8,694 canine orthopaedic cases, fractures not included, patellar luxation was diagnosed in 559 dogs (801 stifles). Mixed breed dogs were most commonly affected (18%), 85% of the luxations were medial, and 52% of the dogs were female. Of the 559 dogs examined, 400 (574 stifles) met the inclusion criteria for treatment evaluation. Minor complications occurred in five percent of the dogs, and major complications in 16%, including recurrence of patellar luxation in seven percent of the dogs. The outcome was good in 88% of stifles, fair in two percent, and poor in 10%. CLINICAL SIGNIFICANCE: Although patellar luxation was more common in small breed dogs, it also was diagnosed in a significant number of large breed dogs, which included medial patellar luxation in 73% and lateral patellar luxation in 27% of stifles. Body weight and grade of luxation were the only variables statistically correlated with surgical complications.
