The researchers followed 32 patients of which half were assigned to shower after two weeks and the other half were allowed to shower once the surgical dressings were removed, which is typically two days post-surgery.
None of the patients developed infections, and those who were allowed to shower sooner were much happier, compared to those who had to wait two weeks.
The researchers wrote, “What is needed now is a larger-scale study that can evaluate if early versus delayed wound cleaning has any effect on surgical-site wound infection risk for [knee replacement surgery].”
