Background: Joint replacement is an important surgery for replacing a damaged joint with prosthesis. Implants used for joint replacement are made of metal, plastic, and ceramic. Skin reactions, such as dermatitis, can occur due to a hypersensitivity to these external substances. Aims: The aim of this study was to find the relationship between joint replacement and dermatitis. Methods: A nationwide population-based retrospective cohort study was performed using the National Health Insurance Service Database of the Republic of Korea. A total of 40,218 patients who underwent joint replacement were enrolled as the operation group and 40,218 controls were also enrolled. A cox proportional hazard regression model, and Fine and Gray regression model were used to compare the risk of dermatitis between the two groups. Results: Dermatitis occurred in 9.2% of the operation group and 9.1% of the control group, and no statistical difference was observed between the two groups. According to the Cox proportional hazard regression model, and Fine and Gray regression model, the risk of dermatitis did not increase in the operation group compared to that in the control group. However, the risk of dermatitis increased 1.20-fold in the operation group compared to that in the control group aged <60 years according to the Fine and Gray regression model (95% confidence index (CI) = 1.05–1.37, P = 0.0008). Conversely, no difference in dermatitis risk was observed between the two groups aged ≥60 years. Conclusions: We found that the risk of dermatitis increased after joint replacement in those aged <60 years.
