@alwaysgg I had right knee replaced in 2020. I have those “bumps” around my kneecap and below it (on the inside part of my knee). At the time, I asked the surgeon on a follow up visit what they were. He replied “Those are just my stitches” and let it go. They aren’t painful but I’m aware that they are there and I can feel them. Getting the left knee replaced (swore that I would never do this again!) with a different surgeon in October. Maybe I will ask him down the road what to do about them.
