Analysis Of Risk Factors For Infection After Total Knee Arthroplasty

Objective:Total Knee Arthroplasty referred to TKA, the Chinese name of total kneearthroplasty. With the knee joint degeneration in patients with increased kneereplacement surgery is increasingly been applied in the field of orthopedics.However, postoperative infection is one of the major complications leading tosurgical failure, has been to impede the development of orthopedic surgery.The event of patient recovery time is extended, to play a serious negativeimpact on treatment; the same time increase the patient ’s pain as well aseconomic burden. In this paper, research and analysis, TKA postoperativeinfection in patients with TKA postoperative infection in high-risk groups toreduce postoperative infection rates, for the sake of future clinical work.Methods:358cases of our hospital orthopedics from March1999to March2011toaccept a total knee replacement surgery patients for the study. Statisticsbetween the different groups the patient’s age, gender, BMI index,preoperative diagnosis, preoperative underlying diseases, previous surgery,operative time, surgical approach, length of stay, blood loss and bloodtransfusion. SPSS statistical software for statistical processing.Results:Infected patients in the analysis of358patients27cases in whichsuperficial infection (18cases), deep infection in9cases, the infection rate of7.5%.27cases of infection in patients cured by conservative antibiotictreatment in11cases,7cases of patients with joint debridement, andcontinuous anti-infective therapy were discharged. The remaining9patientsfor two replacement surgery, infection without evidence of recurrence8monthsmedian follow-up after discharge. Conclusions:The elderly patients, especially male patients, the infection rate wassignificantly higher than female patients, risk factors of infection after TKA.Around the knee tumors, traumatic arthritis, rheumatoid arthritis risk factorsfor infection after knee replacement. For double knee replacement in patientswith more preoperative complications, and poor general can be considered OKphased replacement surgery, there is the possibility of a reduction inpostoperative infection. Reduce operative time, intraoperative blood loss andblood transfusion can effectively reduce the TKA postoperative infection.
