@dtmbf so glad to hear things are going well for you too. I too had my second RTKR on May 18th, so I like seeing how you're doing in comparison to myself.
I'm finally done with outpatient PT and doing pretty well, though stairs will probably be a problem for me the rest of my life. I can do them but only with two hand railings or one railing and my cane, but I'm so glad to be out and about and taking care of myself again that I can live with that minor problem.
A good night's sleep is now again possible about 98 percent of the time, and that has really improved my outlook on life. Grocery shopping takes a toll, and I usually need a nap after I get home and put things away (could be recovery, old age or both); but generally my energy level is improving. All in all, things are pretty good. I can get around in the yard again, though I do use my cane then just for safety's sake.
I am having a problem with my right leg still feeling longer than my left leg. I saw my OS two weeks ago and he said my knees are level and showed me on the x-rays that had just been taken that they are definitely at the same height. He said it could take several more months for my muscles/tendons/ligaments to readjust, because I had been walking around for almost three years with a loose knee joint that threw everything out of kilter. We'll see.
I too have numbness and a feeling of heaviness on my left knee, which was replaced for the second time 3 years ago, but mine is in the upper left quadrant and covers an area about the size of my hand. I think it will always be there, but I've grown accustomed to it and don't notice it most of the time. The only time it really bothers me is when I stand in one place for more than a few minutes.
You're lucky that you can kneel down. I've tried but even with knee pads it hurts. Actually, the OS that did my original knee replacements 15 years ago, told me I should never kneel on my new knees. I don't sit on the ground anymore either--it's too hard to get back up without having something to push myself up on. It's not the worst thing in the world, but sometimes it's those little things that bother me the most sometimes.
Even with all the pain and recovery from six knee operations, it was well worth it to have knees that are no longer painful, and I can live a relatively normal life again. I may not be able to do everything I did when I was younger, but I can do most of what I want to do now at the age of almost 65 years.
I hope you have a fun trip out west. Good idea about the wheelchair in Atlanta...it's always better not to overdo it.
