Introduction. Today, knee arthroplasty is one of the most common surgical procedures. Infection after endoprosthetics is the most dangerous complication in patients who have undergone total knee arthroplasty, which negatively affects the prognosis. Most cases of infection develop within the first 2 years after surgery, and the frequency is 1.5%, and after that it decreases to 0.5%. Material and Method. When a study group of 31 patients (22 female, 9 male) who were diagnosed with infected knee prosthesis and underwent two-stage revision knee prosthesis as a treatment method; the mean age of all patients (31 patients) was 68.78 years. In our study by using the American knee association scoring system; preoperative knee scores of 31 patients who underwent two-stage revision surgery were 35.43 ± 7.14, while this parameter was found to be 83.27 ± 8.89 postoperatively (p <0.01). Conclusion. We believe that two-stage revision surgery is an effective method in the treatment of infection that develops after primary total knee arthroplasty application. Restoration of the joint line in accordance with the anatomical structure will positively affect the clinical results, and the use of a long stem to increase the stability of the prosthesis is appropriate for successful results, especially in the cases with bone defects.
