I'm 8 weeks out of a Left TKR. About 2 weeks ago I noticed a little "hole" at the top of my incision scar. I showed my OS at the last visit 2 weeks ago and he said it'd heal up on it's own, but I could put a little bandage on it if I liked. I didn't, thought it would heal up, but today I noticed a little piece of nylon string sticking out. About 1/4" long, maybe a bit smaller. It's now mostly sucked back in, but a bit is still out, maybe 1mm. So I put a bandage over it, a water proof one, and now don't know what to do! Any good ideas? I go back to my OS in two weeks. That seems like a long time to wait!
