About two weeks ago I had arthroscopic surgery on my left knee that involved a lateral release of my patella. Tonight I came home and noticed drastic differences in both the bruising and incision sites. The bruises have been dark purple but now there are odd white spots in the middle of these dark bruises. They don't feel hard but they are rather noticeable. The incision sites are raised, red, hard, and really itchy but emit no extra heat or leakage. Until this point I have had no complications; actually quite the obvious with the very little bruising for the first week to week and a half. There has been next to know pain since the day after surgery. I'm mobile and off crutches. The only thing I have done tonight for this is clean the incision sites with hydrogen peroxide and replace the bandages. Has anyone else expereinced this? Do I need to be concerned? Should I go to the ER? I'm not sure if internal stitches were used for me to reject. There is no streaking and I don't have a fever.
