Hi Roy. I had my right knee done 8 days ago and getting my left knee done in 3 weeks so you can follow my progression. Almost a bilateral - dr would not do both at the same time. I decided to do this because of financial reasons but also because my left knee is as bad or worse than the right and I don't want a prolonged recovery period. I am extremely fortunate that I can work from home so am taking only 2 weeks off for each knee. Of course, if my right knee doesn't go well, that may change but we will see. I cannot imagine doing this in the summer when I'd be itching to go outside! I am mentally preparing myself for a rough time after the 2nd knee is done, but at least there won't be anything to stop my recovery. Intend to be on the bike, the trail and in my kayak by Spring.
