Oh God don’t! Had a repair surgery, didn’t fix it. Had a Total Knee replacement, surgeon assured me that I’d been raring to go in 90 days. That was in October of 2016. Now, keep in mind, I went to the God Of Knee Surgeons. Did all the PT, did extra PT. How is it now? Hurts as bad or worse than it did prior. What they don’t tell you is (and there is more than one thing they don’t tell you) if you happen to be profoundly knock kneed, this replacement will straighten your leg to perfect. Two things happen. First, your surrounding ligaments and tendons are pissed off. Really pissed off. They were fine for 55 years and saw no reason to change. Second, you know how if you straighten out a piece of metal it’s now longer? Yep, but you don’t realize that your “new and improved knee” is going to be a half inch longer than your “currently unaffected knee”. You ride, you dance, you have done things your entire life that enable you to control your limbs and muscles down to a fraction of an inch, so a half inch difference is enormous to you. Eventually if you complain enough, PT will make you a lift for the other shoe, and that will help… as long as you are wearing that shoe. Because your new knee hurts, you’ll overuse the other one that wasn’t quite as bad, and it will begin to be agonizingly painful. You may have annoying and painful complications that no one mentioned were possible. Google Chronic Regional Pain Syndrome, for months I couldn’t stand to have anything touch the incision site, I had to sleep with several layers of tegaderm over it because even the softest blanket made me feel like I was being branded. On a scale of 1-10, it’s a 6-7 most days. I have good range of motion, decent strength, but am in pain every hour of every day. Do I need the other one done? Absolutely. Am I going to have it done? when I am dragging it behind me and my toes are bleeding I’ll consider it. Do your homework and ask what the “worse case scenario” is. Of course if I’d lose the extra 40 lbs I packed on over the last 4 years, it “might not” hurt as much. Except I can’t run, or really do any cardio stuff except swimming. Still on medication for the angry nerves. I have friends who had no trouble with two right away and friends who never rode again. Just be informed completely. No way would I do two at once. The one I haven’t done hurts like a bitch, but it still works.
