Hi again,
It shouldn't really take a year to get pain free. It could take a year for your knees to finish healing, but they shouldn't hurt you for all of that time.
There's no absolute given that the other half of your knees will ever develop arthritis - and no guarantee that they won't. It's a possibility, but not inevitable. If you can, do try not to worry about that right now.
When I had to go from partial to full replacement, I was scared. I imagined a recovery like the one I had for the partial, only worse. It wasn't like I imagined! If anything, my recovery was better, because I was better prepared for it. I had found BoneSmart and taken all the advice here to heart. I knew all about elevating and icing the second time around, which I had not known about the first time. I knew about pacing myself, resting plenty and taking my medications by the clock. It made a huge difference and I actually felt as though my recovery was easier.
Don't go rushing into a revision to full replacements just because I told you that! If you can hang in here and give those partials a chance to settle in and for your knees to heal, you might feel better about them in a few months. I do think that going back to your surgeon might reassure you right now, though. He will be able to check that there is nothing wrong with the replacements, or with the other compartments in your knees.
It's really hard to lose your mother and that happened at a particularly bad time for you. You'll always miss her but, if it's any consolation, the acute pain of your loss will decrease as time goes by.
Did you know that most of us have a period during our recovery when we get quite depressed? It comes with the territory and is often part of the recovery process. It's like the after-baby blues, only worse! Couple that with grieving for your mother, and it's no wonder that you feel down! Can you talk to your own doctor about that? Maybe he can suggest some short-term medication that will help you get out of the pit of despair?
I wish you all the best and I really hope that you start to feel better soon. Meanwhile, keep talking to us. We're here to listen!
