Title: Patient-related risk factors of prosthetic joint infections following total hip and knee arthroplasty at King Abdulaziz medical city, a 10-year retrospective study
Introduction: Total joint arthroplasty can be associated with the development of periprosthetic joint infection. This severe complication needs focused care and management. Moreover, it is necessary to develop a baseline for the possible modifiable and nonmodifiable correlated risk factors for developing PJI to provide the optimum healthcare to the TJA candidates. Methods: The study sample consisted of 1198 participants who had undergone either hip or knee arthroplasty from 2015 to 2022 at King Abdulaziz Medical City, Riyadh. The data analysis process of this study included two stages. The first stage included a descriptive analysis The second stage included bivariate analysis, which were applied by IBM SPSS Statistics 25.0. For all the subjects, we have reviewed the sociodemographic data, the medical history, surgery details, and whether a periprosthetic joint infection was present postoperatively. Based on the 2013 international consensus Meeting (ICM) modified musculoskeletal infection society (MSIS) consensus-based criteria, the diagnosis of the prosthetic joint was made. Results: The study sample consisted of 1198 participants underwent TJA. The mean age of the subjects was 63 years. Among the 1198 individuals, only 1.3 % had a prosthetic joint infection diagnosis (PJI). No significant comorbidity was detected. General anesthesia was used in almost 21% and was statistically significant for having a higher risk of infection (p-value of 0.049). Moreover, increased OR time was significant for developing PJI with (p value= 0.012). In addition, in our study, TXA was a protective factor in reducing the risk of PJI with a (p-value = 0.017). Conclusion: Even though periprosthetic joint infection is not a common complication of TJA, multiple risk factors play a significant role in its development, such as general anesthesia and prolonged OR time. In contrast, tranexamic acid administration is thought to reduce the risk of PJI effectively.
