Well here I am, 1 week out and my nerves are beginning to get the best of me. I had my pre-op today. OS tried to draw fluid off my knee to check for infection and could not get past the scar tissue! So, tissue sample will be taken during surgery and sent to pathology while I am still on the table. Tonight my knee is killing me! Blood test does not show infection, and I appreciate his thoroughness, but my knee still hurts tonight. I don’t want to think about the process, should it be determined I have an infection.
