Detection of Four Infection Indicators in 20 Patients with Knee Infection after Operation

［Abstract］Objective　To investigate the detection results of WBC， CRP， ESR and GR% in patients with knee infection after operation. Methods The study was conducted from March 2012 to January 2015. Twenty patients were collected in the study. The values of WBC，CRP，ESR and GR% were compared and analyzed between pre-operation and post-operation of 1，3 and 7 days. Results The values of WBC，CRP，ESR and GR% in the post-operation of 1 day were higher than those in the pre-operation，and there were statistically significances（P < 0.05）. The values of ESR in the post-operation of 3 and 7 days were higher than that in the pre-operation， with statistically significances（P < 0.05）. However， the values of WBC， CRP and GR% in the post-operation of 3 and 7 days were no statistically significances compared with those in the pre-operation （P > 0.05）. Conclusion WBC，CRP，ESR and GR% have good reference value for early diagnosis and treatment， which can be used as screen testing indexes in the early knee infection.
