I did not to shower for two weeks. I was told that I could shower once I could manage in the shower (on a chair) but under no circumstances to let my incision get wet. I was told to wrap the knee/incision in Glad Press N Seal. They told me to use this when I was at my pre surgery joint camp at the hospital. I waited two weeks, because #1 I was scared of getting it wet too early, and #2 I think I needed the two weeks to be able to manage in the shower. You will just have to see what your OS says for you to do.
