Introduction: Due to few lack of researchs in the field of changes of inflammatory factors after of post-operative knee surgery in our country in order to improve the health status of the patients, in this study, erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) and white blood cells (WBC) changes after uncomplicated arthroscopic anterior cruciate ligament reconstruction of the knee were investigated.
Methods: In this prospective experimental study, patients undergoing arthroscopic anterior cruciate ligament reconstruction and with uncomplicated postoperative course of the knee in Imam Hospital were studied.
Results: (write numbers of patients , male and female,mean age)CRP levels peaked picked in day two 2 after post surgery and then declined till day 7 returned to the pre-operative levels in day seven. ESR in patients after surgery has been picked peaked on the second post-operative day, and returned to the levels before surgery 14 days after surgery, returned to the levels before surgery. The age of patients had a direct correlation with postoperative CRP on the seventh and twenty-eighth, respectively r = 0.39, P = 0.04; r = 0.84, P = 0.009. patient age had a direct correlation with ESR day 7 and 14, respectively r = 0.49, P = 0.012; r = 0.44, P = 0.046.
Conclusion: post-operative CRP and ESR levels returned to pre-operative levels in days two and fourteen respectively.(also write about WBC,smoking) If CRP and ESR levels not reduced after the seventh and fourteenth day, respectively or increase again, definitive diagnosis of infection should be investigated.
