Sebastian M. Klim MD and Mathias Glehr MD Department of Orthopaedics and Traumatology, Medical University of Graz, Graz, Austria Prosthetic joint infection (PJI) after TKA is among the most frequent indications for revision TKA.1–4 A huge economic burden is associated with the increasing number of (septic) revision TKA.5 One of the most frequent causes for wound contamination is skin microflora. With the incision made during surgery, micro‐organisms may be able to infect tissue, joint, and/or implant. It is a widely accepted fact that the use of an antiseptic skin wash product can reduce skin microflora. However, there is no consensus whether this leads to a reduced incidence of SSI/PJI.6,7 Knowing the history of the patient, you want to know if bathing/showering with antiseptic skin wash products prior to surgery can help prevent an SSI/PJI. The level III meta‐analysis results (total study population) indicate a reduced incidence of SSI when chlorhexidine (the active substance in all investigations) was used in preoperative washing/wiping (risk ratio [RR] = 0.22; 95% confidence interval [CI]: 0.12–0.40; p = 0.000). Furthermore, a reduction of SSI rates in moderate and high risk patients according to the National Healthcare Safety Network (NHSN) risk classification is shown (RR = 0.18; 95% CI: 0.05–0.63; p = 0.007 and RR = 0.13; 95% CI: 0.03–0.67; p = 0.014.8,11 In contrast, the level I systematic review as well as the retrospective comparative study found no benefits in the chlorhexidine groups regarding SSI incidences. A discrimination by risk classification has not been performed in these studies. Insignificant differences in SSI rates are reported in the chlorhexidine and in the placebo groups (RR = 0.60; 95% CI: 0.22–1.60; p = 0.330.8–10 Multidisciplinary perioperative treatment protocols for TKA have been presented and further advanced in recent years, aiming to provide standardized treatment leading to a reduced length of stay, improved clinical outcome, and patient satisfaction.12–14 To achieve this, physicians, anesthesiologists, physiotherapists, and nurses must closely work together and adhere to evidence‐based protocols, known as fast track (or FT).

Clinical scenario
Top three questions
Question 1: In patients scheduled for primary TKA, does preoperative bathing/showering or wiping with antiseptics result in fewer SSIs compared to nonantiseptic preparations?

Question 2: In patients after primary TKA, does a fast‐track (FT) early‐mobilization schedule lead to an improved outcome in functional scores and hospitalization time compared to a regular joint care protocol?
