Well, Jo, apparently my collateral ligaments are fine. Though they take a beating due to the leg shifting from laxity. So not sure what he meant by "more constrained" femoral component.
I was impressed with this guy's approach. He took a good history -- asked me to describe my problem in my own words -- and then did a good physical exam. He knew what he needed to know without looking at xrays or reading the notes from my previous surgeries.
Minnie, yes the FRUSTRATION. My knee looks ugly, it never feels normal, it's constantly swollen, my quad is atrophied. I was told it will never get better although there's room for some quad strengthening. However, the quad will never be completely normal as long as the knee is like this due to some neurological feedback loop.
We did a lot of walking in NYC and while I would expect to be tired, what happened to me went far beyond tired. I am completely spent. Suspect but don't know for sure that the knee is a major factor.
I continue to lift myself off toilets and out of chairs with my arms. It's hard now. I can only imagine what it's going to be like in 10-20 years. The decisions I face are not just for today for for my so-called golden years.
What really annoys me is that pre-TKR, I dealt with the exact same problems. TKR was supposed to solve them. In some ways I was better. For instance, I could stand up using just my legs. I had a little more pain but not much. I am really mad to be in this fix.
