For anyone who wants to know what a total knee replacement looks like 2 weeks post-op, here’s mine today just after having removed the dressing. Slightly longer scar than I had been led to expect, but no stiches/clips but glue. Still swollen and uncomfortable, but definitely on the mend.

Notice about 2/3rds the way down the incision, a small scar on each side where I had arthroscopy some 10 or more years ago.
