@lawanna85 Welcome to Mayo Connect, where we support one another through the ups and downs of our health journeys. As the recipient of two total hip replacements in my early 50's and 3 revisions at age 60, I am wondering why you have chosen to have both knees replaced at the same time. These are major operations, and rehab takes a good bit of time. doing both at once (which my hip surgeon said he "wouldn't even consider except in an emergency") seems like a lot. In addition to the healing and rehab, which is extensive, you are not giving yourself a "leg to stand on" should something go wrong with one of the new knees.

As for a rehab facility, whether you have one or both knees done, a good one can be very helpful. PT is right there, staff is on hand to notice right away if something is wrong, and your day-to-day needs are taken care of so you can concentrate on healing. They also have an overhead grab bar available that is very helpful for repositioning yourself in bed - if you haven't had major ortho surgery, you might not believe how difficult that is in early days after surgery. My friend, who lives alone, had a hip replacement after a fall, and went to rehab, where they quickly recognized that her "slow start" on healing was due to low sodium and low hemoglobin. At home, she may have waited for days or weeks, thinking it was all part of the healing process.

On the other hand, if you are fortunate to have someone in your home who is a great caregiver and skilled observer, you might feel more comfortable in familiar surroundings. If that is your plan, make sure to prearrange for everything before surgery - easy food, a bedside or over-bed table for necessities, a shower bench or chair, reachers, an ice device so you are not having to change ice packs constantly, no throw rugs...

Once again, I will ask, are you sure you need to do both at the same time?
