RESUMO
BACKGROUND: Periprosthetic infection after total knee arthroplasty (TKA) has become the most serious complication. However, there is still a lack of clinical study on the distribution of pathogenic bacteria. Therefore, understanding the distribution characteristics of the main pathogenic bacteria is critical for preventing and treating OBJECTIVE: To analyze the bacteriological characteristics in the patients with periprosthetic joint infection following TKA, so as to provide reference for early prevention and treatment. METHODS: CNKI, VIP, WanFang and PubMed databases were retrieved for the literature concerning periprosthetic infection following TKA published before 2016. The incidence of periprosthetic joint infection after TKA was statistically analyzed. RESULTS AND CONCLUSION: (1) 103 articles were included, involving 1 399 patients. (2) The main pathogenic bacteria were Staphylococcus aureus,coagulase negative Staphylococcus aureus,Staphylococcus epidermidis,Escherichia coli, Streptococcus and Enterococcus.There is no significant difference in the distribution of bacteria at home and abroad. Treatment strategies are divided into conservative and surgical treatments. (3) The key for successfully preventing and treating periprosthetic infection after TKA lies in the multiple disciplinary team collaboration, understanding the distribution of bacteria, early diagnosis and active preventive measurements, as well as rational treatment strategies.
