Kati, you have no idea how many times last year I kept rationalizing that I didn't really need that RTKR (despite knowing the L's been bone-on-bone for years, doubting that the R--compromised by a failed torn lateral meniscus repair and enough titanium hardware holding the tibia together to build an F-15--was "that bad")! I kept asking myself why I was willing to put myself through the risks of surgery, post-op pain and an arduous recovery. Then each time I was ready to call it off, that dang meniscus would pop with a ripping pain and my knee surfaces would grind together (and I was going through so much diclofenac gel, Flector patches and Aleve that I eventually burned a divot in my stomach). I phoned everyone I knew who had it done, expressing my concerns. On the day of surgery, on my way from the waiting room to the pre-op suite I kept asking the nurse if I was really doing the right thing.
Know what they ALL said? DO IT!!!! DO IT ASAP!!! The fact is that none of us is getting younger and that advanced bone-on-bone osteoarthritis does NOT get better without surgical intervention. The longer you wait, the worse shape your knee will be, the longer and harder recovery may be, and the older and less robust you will be. Today's implants usually last far longer than the 15-20 years estimated at the dawn of joint replacements--especially if you take proper care of yourself.
Did recovery hurt? Oy vey. Duh. But guess what: little by little, you get better and better and better. Do I still get some soreness and discomfort in my R knee? I won't lie to you--I do. It's not as comfy as it was before the cascade of injuries set OA in motion beginning at 40. But compared to how it was in the five years before the RTKR? Not even close--and whatever discomfort I still get goes away after a few steps or flexes. The important thing is that post-surgical pain, as intense as it is at first, only gets better and wanes over time--and you will suddenly realize that your pre-op pain was far, far worse. And pre-op OA pain? It only gets worse. Most importantly, the better shape your joints are in, the easier it is to become fit.
To paraphrase Larry the Cable Guy, "git 'er done." I wish I'd been young and fit enough to have done mine bilaterally, but my R tibia was in such sorry shape and I was so heavy that I had to spend too long in surgery to risk having the L one done at the same time. I am not looking forward to the first few weeks after my LTKR, but I'm sure looking forward to how much better my L knee will feel a couple of months out--and to having a matched set so I can more easily exercise (and have nothing interrupt my sleep but amour, nightmares, alarm clocks, or an affectionate 15-lb. kitty with untrimmed claws).
