This is an odd question since I had my first tkr in January, 2017 - but because of the numbness in my leg, I really don't know what to expect insofar as how my next one will feel in the future. My left (new) knee doesn't have the grinding bone on bone pain, but it feels like a large watermelon strapped to my leg....not painful, just constantly aware of it even though i'm very grateful to have it. Guess what I'm asking is are you aware of your new knee(s) 18-24 months out? If you didn't know you'd had a tkr, would you know your knee was any different from the one you were born with? Since I don't have neuropathy in my right leg, hopefully that will be the result after my second tkr next week. Am I expecting too much?
