Purpose: Two-stage revision is the gold standard for treatment of infected total knee arthroplasty. The purpose of our study was to evaluate the reinfection rate of two-stage revision and to analyze the factors affecting the prognosis of two-stage revision for infected total knee arthroplasty. Materials and Methods: One hundred seven cases of two-stage revision for infected total knee arthroplasty were reviewed retrospectively from March 2006 to November 2019. We evaluated possible risk factors between success and reinfection groups. Statistical analyses included multivariable logistic regression analysis to examine the relative contribution of risk factors to the success of two-stage revision. Results: There were 19 cases of reinfection (17.8%) after two-stage revision in our center. Between the success and reinfection groups, there was a significant difference in history of cancer in univariate analysis (p=0.015). Also, multivariable logistic regression analysis of risk factors demonstrated history of cancer (HR 5.928, p=0.015). There were no statistically significant differences in reinfection relative to other risk factors. Conclusion: In subjects undergoing two-stage revision for infected total knee arthroplasty, we believe history of cancer should be considered for risk factor of reinfection.
