Abstract :Introduction: We aimed to evaluate the relationship between complete blood parameters reported to be associated with inflammation and development of complications, length of hospital stays and the number of antibiotics used in elderly patients undergoing revision total knee arthroplasty insert ignore into journalissuearticles values(rTKA);. Material and Method: Our retrospective study was conducted in a single center and included 72 older patients who underwent rTKA operations. We recorded patients’ firs day preoperative, first day postoperative and 45th day postoperative whole blood parameters. Results: It was found that the development of postoperative infection and the number of antibiotics used were higher in patients with low preoperative Hb values and high platelet-to-lymphocyte ratio insert ignore into journalissuearticles values(PLR); rates. In patients with high RDW value and high eosinophil-lymphocyte ratio insert ignore into journalissuearticles values(ELR); one day after surgery, both the development of infection insert ignore into journalissuearticles values(P=0.002, P=0.002); and the number of antibiotics used during follow-up were found to be significantly higher ​insert ignore into journalissuearticles values(P<0.001, P<0.001);. When the laboratory parameters were evaluated 45 days after the operation, it was determined that the RDW insert ignore into journalissuearticles values(P=0.001, P=0.001); and ELR insert ignore into journalissuearticles values(P=0.039, P<0.001); elevations continued in the patients who developed infection and used multiple antibiotics. CRP and ESR values one day and 45 days after surgery were also found to be significantly associated with the development of infection and the use of multiple antibiotics. Conclusion: RDW, ELR and PLR parameters may be as important as CRP and ESR in predicting the development of infection and the number of antibiotics used in elderly patients undergoing rTKA.
