Hi, I had both knees replaced last year (2018) 4 months apart. One in Oct and the second in December. I still am unable to kneel without a lot of discomfort on my incision scars. It's not the knee that hurts, just where the scars. I've tried kneeling on a pillow, etc. I still can't stand it for more than a few seconds. Will this ever improve? Thanks for any feedback.
