Sorry about your setback, dananddeb. I hope rest and PT will make it better.
I am in my 5 th wk postop rtkr. I have had a great recovery thus far, but I am grateful for this thread, and have something to contribute, I think. My dislocation, and the resultant surgery, 26 yrs ago, resulted in a total loss of surface, or skin, sensation from just below my knee to my ankle. It was explained to me then that the emergency surgery to save my leg sacrificed some nerves. It took a couple yrs to get used to, but i finally decided I was more glad to have the leg. When the band aid surgeries stopped working, they put a cadaver achilles in to replace my pcl. No additional sensation loss then, but the reality that I (gratefully) have some other kind, departed soul's parts in me was a psychological hurdle, to be honest, even if it seems selfish to say so. But, you'd better believe I am an organ donor!
My rtkr 5 wks ago was precipitated by much anxiety and consternation. What? Me give up my real parts, however broken they are, for man-made replacements? Well, i am sitting right now, soaking my knee in a tub as I came down on it hard and wrong last night getting out of my car. It will likely take the weekend to recover from that. But, that said, I am thus far thrilled with the abilities I have regained. I am doing things, like picking up after myself, putting storage away, etc., that I wasnt doing before, but in no way was I attributing that to my knee. I also am walking farther than I used to be able to without the pain i had before.
Yes, sleeping is weird with the significant knee numbness. I kept waking up last week for two nights thinking that as I tossed and turned in my sleep that I would leave my lower leg behind and spin my upper body (which is the mechanics of my original injury, while skiing). I had bad dreams about it. But I slept well last night.
My knee clicks like there is no tomorrow. Part of it is the remaining swelling keeping the patellar button from tracking directly on the other replacement parts. But, the sounds are not accompanied by pain.
This is a long, slow road of recovery. I urge you to seek out the positives, and learn to live with the other changes, and consider your new knee a new lease on life. And that, my friend, is a decision we all must make.
Best wishes to all!
