Long time "reader" first time poster. I've found this site to be very helpful, thank you! As the title describes, I had a total TKR on my right knee 9 months ago, at 64 years young. The first couple of months were rough, but now I can get around fine, but really hurts to get up from a sitting position. My left knee is getting worse and I fear it's next. I'm able to walk without much problem, just stiff and hurts to step up or down very often. I've been riding my bicycle around 20 minutes a day, it only pains me when I'm first pushing off from a stop. I think I lost some progress because I got Covid in early March and was in bed for a couple of weeks, very sick. I guess I'm looking for affirmation that it "will" get better. I hear of so many that take a full year, while others are better much sooner. The pain is mostly on the right side of the surgical knee, slight to the back of it. Nothing seems to help this. I've been avoiding the gym, in case I've lost antibodies already. Okay, I've gone on long enough. Any advice/suggestions would be greatly appreciated!
