Investigators of this study reported surgical site bacterial recolonization was not significantly different between patients who took showers 2 days postoperatively and patients who took them 2 weeks after primary total knee arthroplasty.
“The major limitation of this study is the small sample size,” the researchers wrote. “With more subjects, it is possible that the small, statistically insignificant changes we observed between our study groups could become significant. However, we do not anticipate any change with the strong patient preference to shower early.”
