I have a hot tub and my OS did not want me in it until after my 6 week office visit. Then I did not get into it for another 2 weeks. I had to be sure everything was healed. No openings for the water to take any bacteria into the joint itself.
So, I would stay out of the hot tub until after you have seen the OS and he or she has approved of getting in one especially if it is a public one! JMO
