I need to know if my wife can stay in hospital room with me, then what is the best mode of travel right after TKR Revision... a 18 hour drive or a few hour flight? Then will these docs be ok with consulting with docs close by for follow up visits, physician release update forms for sick time from work etc.
You'll have to ask your surgeon about your wife staying with you and about follow-up arrangements.
I don't think either of those travel options is wise. Flying so soon after surgery, you would increase the risk of developing a deep vein thrombosis (DVT) and the journey will be stressful and very uncomfortable for you.
Flying soon after surgery
Bear in mind that you will be in pain and will need heavy-duty medications for pain relief. These will make you tired and sleepy. Most people don't want to do anything more than lie in bed or take very short walks.
As for doing an 18-hour car journey - well, you won't be able to do that in one day. You'll need to break the journey up into 3 days at least, with overnight accommodation en route.
While you will be able to travel sitting cross-ways across the back seat, with your leg elevated and iced, you will need to stop about every hour to walk and stretch. That will add hours to the journey each day.
At 4 weeks post-op, I did a car journey that normally takes 4 hours. With a meal stop and shorter stops along the way, that journey took us 7 hours.
It's big risk to travel so far, so soon after major surgery, and it's also a huge responsibility for your wife. Have you discussed this with her?
I think you would be wise to try and find a surgeon skilled at doing revisions, who is closer to your home in Memphis.
