### Question: Wound Hygiene Practices After Total Knee Arthroplasty: Does It Matter?

### Context: 1: Current literature is limited with regard to standardized postoperative surgical site hygiene after total knee arthroplasty (TKA). With little guidance from the literature, the timing of permissible postoperative cleaning is a decision made by the individual surgeon using anecdotal evidence. A standardized wound care regimen is of particular interest to minimize the risk of infection.
2: To examine what species of bacteria recolonize the surgical site postoperatively, a randomized controlled trial was performed of 16 TKA patients who were allowed to shower at 2 days postoperatively and of 16 patients who were asked to wait until 2 weeks postoperatively before showering after TKA. Culture swabs of skin adjacent to the incision were performed preoperatively, just after incision closure, at dressing removal, and at 2 weeks postoperatively. Bacteria were speciated and compared between groups. A swab of the contralateral knee was performed at 2 weeks as a control. A survey of patient's preference regarding early and late showering was also carried out.
3: No difference was found between the groups in rate of colonization or bacterial type, and no patients developed infection. Patients overwhelmingly preferred early showering rather than late (P = .28-.99).


###Response: There is no difference in surgical site bacterial recolonization between early and delayed showering after primary TKA.
