Start the PT exercises BEFORE the surgery - leg raises, foot slides, bridges. I can’t remember them all but your surgeon or PT will have a printout. If you can’t do them prior to surgery don’t expect to reach your PT goals after. I had complications after one surgery due to an over zealous PT so know your own limits.
Practice the bed roll BEFORE the surgery. There are videos.
Get Senna tea and have a liquid diet ready if you get constipated by opioids, like I do. The constipation was worse than the surgery - lol.
I don’t know how old you are but I have mild urinary incontinence when I have a lot of pain in my legs so have pads available. It will take effort to move around so you may not get to the bathroom in time.
Everyone is different, and every operation is different so how you handle the pain, etc is personal. I have had 2 TKRs and 2 THRs - all different - even the ones with the same surgeon. Because I get constipated with opioids, I just take NSAIDS and they work well enough for me - but I accept the opioids for when the pain peaks. The opioids don’t work as well for pain for me but they make me feel “happier”. Scary, right? I avoid them.
