Congrats on your brand spanking New knee- I had Both of mine done around 3 and a half months apart and I am glad I did- They have their good days and their bad days. It is a rollercoaster, but I have never once regretted doing them close together. The pain that I ever have now is only healing pain, which if I was not on this site and did not know any better that it takes a year to heal up, I would be extremely worried that they still felt stiff and swollen some days, but after my right TKR in january, I really stressed out lefty , by making it my anchor knee, it started going south a few weeks after surgery number #1 and I really didn’t have a choice anymore. Best wishes on a great recovery!
