AbstractThe aim of this study was to track the annual rates and trends of overall, deep, and superficial surgical site infections (SSIs) following total knee arthroplasty using the most recent results from a large and nationwide database. A total of 197,192 cases were performed between 2012 and 2016 from a nationwide database stratified into years and based on superficial and/or deep SSIs. Cohorts were analyzed individually and then combined to evaluate overall SSI rates. The infection incidence for each year was calculated. After a 6-year correlation and trends analysis, univariate analyses were performed to compare the most recent year, 2016, with each of the preceding 4 years. Overall, there was a downward trend in overall SSI rates over the study period (2012–2016, with the lowest rate occurring in the most recent year, 2016 [0.11%]). Additionally, there was a decreasing trend for superficial SSI, with the lowest superficial SSI incidence occurring in 2016 (0.47%) and the greatest incidence occurring in 2012 (0.53%). An overall trend of decreasing SSI rates was observed nationwide over the 5-year period evaluated. A similar decreasing trend was also noted specifically for deep SSI rates, which can be potentially more complicated to manage, and result in decreased implant survivorship. The down trending SSI rates observed give potential credence to the value for newer and developing SSI preventative therapies as well as improved medical and surgical patient management. Nevertheless, there is still room for improvement, and continued efforts are needed to further lower SSIs after total knee arthroplasty.

Abstract Background:Malnutrition is reported as one of the risk factors for surgical site infection (SSI). The prognostic nutritional index (PNI) is a simple method for nutritional evaluation. However, few studies have discussed the effectiveness of PNI as a nutritional assessment in predicting SSI after primary total knee arthroplasty (TKA). The aim of this study is to investigate the relationship between SSI and malnutrition as identified by the PNI scores following TKA. Methods: A retrospective analysis of 483 patients (SSI vs. non-SSI group: 19 vs. 464; follow-up period: at least 1 year) was performed to confirm the risk factors, including the PNI, associated with SSI after primary TKA using both univariate and multivariate analyses. Results: Postoperatively, nineteen patients (19/483, 3.9%) experienced SSI (deep vs. superficial SSI: 12 vs. 7), and periprosthetic joint infection was observed in all deep SSI cases. Univariate analysis showed that male sex, body weight, body mass index (BMI), diabetes mellitus, steroid usage, operative time and PNI differed between the SSI and non-SSI groups (P<0.05). Multivariate logistic regression analysis identified that the preoperative PNI (odds ratio [OR]: 0.859; 95% confidence interval [CI]: 0.762-0.969; cutoff [CV]: 49.27), operative time (OR: 1.005; 95% CI: 1.000-1.010; CV: 131.0 min), male sex (OR: 4.127; 95% CI: 1.165-14.615), diabetes mellitus (OR: 6.133; 95% CI: 2.067-18.193) and steroid usage (OR: 6.034; 95% CI: 1.521-23.935) were independently associated with SSI (P<0.05). Conclusions: A low preoperative PNI associated with malnutrition was demonstrated to be an independent risk factor for SSI following primary TKA. Patients with preoperative low PNI should be cautioned and provided with adequate nutritional intervention to reduce postoperative SSI.
