Abstract
Purpose
Vancomycin powder (VP) has been used to prevent periprosthetic joint infection (PJI). However, studies investigating the efficacy of VP to prevent infection in primary total knee arthroplasty (TKA) are very rare. The purpose of this study was to investigate the efficacy of VP application to prevent PJI in TKA.
Methods
Between 2012 and 2016, 976 consecutive patients who underwent primary TKA were included in the present study. Patients were divided into two groups. There were 474 patients (48.6%) in the VP group and 502 patients in the control group (51.4%). Except for VP, all procedures were the same in both groups. In the VP group, 2 g of VP was poured into the joint just before the fascia was closed. Average follow-up was 53.2 months (24–84 months).
Results
Infection was found in 4 (0.84%) of 474 patients in the VP group and 5 (0.99%) of 502 patients in the control group. There was no statistically significant difference between groups in terms of infection rates (p = 0.535). Staphylococcus aureus was found in 2 patients in the VP group. Two patients had S. aureus and 1 patient had Pseudomonas aeruginosa in the control group. There was no statistically significant difference between groups in terms of demographic parameters (p > 0.05).
Conclusion
Intrawound VP administration doesn’t change the infection rates in primary TKA. The VP administration for preventing PJI is not recommended in primary TKA.
