Methods: A total of 296 individuals were included in the study. Primary KOA was confirmed according to the criteria established by the American College of Rheumatology. A real-time PCR-based DNA genotyping method was used to evaluate the rs3740199, rs1871054, and rs2073508 polymorphisms in 132 cases and 164 controls. Results: Our results demonstrate that the ADAM12 rs3740199 polymorphism was significantly associated with primary KOA under the recessive model (p = 0.036). However, after performing a multinomial logistic regression model, no significant association was found (p = 0.722). Furthermore, no associations for the rs1871054 and rs2073508 polymorphisms were observed in this study. Conclusion: These findings suggest that polymorphisms within the ADAM12 and TGFB1 genes may not have a significant influence on primary KOA susceptibility in the Mexican Mestizo population; however, inclusion of other ethnic groups and a larger sample size are needed to more fully analyze the role of these polymorphisms with KOA risk.
