Abstract
Introduction: Patellar dislocation represents a significant cause of lameness in toy dogs . In this study, the prevalence of patellar luxation and associated factors, including age, gender, breed, direction of dislocation, degree of dislocation, and dislocation type were investigated. Methods: A total of 133 toy breed dogs were referred to one radiology imaging center evaluated over a two-year period (November 2018 to September 2020). Firstly, the dogs subjected to a clinical examination to identify any abnormalities. Subsequently, radiographic imaging was conducted in two different positioning ,that is, craniocaudal and right lateral . Subsequently, the findings were subjected to analysis with the objective of determining the prevalence of specific factors and diseases in toy dogs. Results: The results of this study indicate that dogs with luxation of the patellar bone (48 dogs) exhibited notable increases in the relative frequency of specific variables, including male (54.2%), under three years old (52.0%), unilateral dislocation (54.2%), right posterior limb dislocation (39.6%), breed (Terrier 40%, Pomeranian 36%),and second-degree dislocation (60.4%). Conclusion: The present study demonstrates that medial patellar luxation is more prevalent than other forms of patellar luxation , including bilateral luxation. Furthermore, the problem mostly was observed in Terrier and Pomeranian breeds. Furt hermore, the results indicated that male sex and age below three years are associated with an increased risk.. Ultimately, luxation represents a significant cause of lameness in dogs. However, this can be effectively addressed through a combination of continuous clinical observation and radiological consultation when necessary.
