Well, I had my one year post-op appointment with my OS today. As I basically already knew, my knee is not doing as well as we had hoped. It's better than before the revision in one way-the constant knee pain is gone. But, my entire leg is still noticeably swollen, and my knee is also still quite swollen. It also has begun swelling even more, and getting pretty hot, when I do a lot of walking, cooking or standing; generally just being on it for long periods. Cooking dinner every day causes a lot of swelling and some pain now, and I have to take breaks to rest it. He's no more thrilled about this than me, and doesn't know why it's still so swollen. The swelling encompasses my leg from above my knee and some of it continues down my entire leg; I even have a noticeable pocket of fluid on the inner/side area of my calf.
The bone has filled in somewhat around the tibial post, but the femur is barely starting to remodel. You can see it on the x-ray and there's a faint, thin halo where the femur bone has begun to make new bone, but you can see a good amount of new bone filling in the tibial area. He also explained to me that the tibia is straight, but the femur is curved, and my femur is more curved than most for some reason (figures) and we can see the post is almost resting on the side of my femur bone, which is why I still get the sharp, shocking, excruciating unexpected pain all the time.
He told me to stay off step ladders and step stools so as to not be on one, move the wrong way, get hit with the pain and then fall off. He also told me to avoid stairs as I'm having a hard time navigating them (he would usually be one who advocates stairs instead of elevators!) and don't over do things in order to avoid extra swelling and pain. Going down stairs I still have to step like a toddler, and going up is difficult, so I have to use the handrail to take some of the weight off my leg so I can climb them.
My femur could still fill in in the future, but at one year, it should have done a lot more, so my hope there is dimming. That would mean at some point I'll need another surgery to correct the problem; I'm not ready to admit defeat on healing yet, but I won't live this way indefinitely either. I do need to do things at times that require a lot of walking, such as mini-vacation trips, shopping and similar; those times I just have to bear the discomfort and pain.
According to him, my flex is about 90, (he eyeballed it as I don't do measurements...lol) which is less than it was in December.

I need to see him again in about three months and he also said to email him occasionally before that to keep him updated. So, it's some good news, and some not-so-good news. Unfortunately, my knee saga continues.
