So after completely tearing the anterior cruciate ligament of my left knee, I underwent ACL Reconstruction using patella tendon autograft. Approximately three weeks after reconstruction, I began to develop signs of infection: heat, redness, severe pain, fever, and systemic red spots. Rehabilitation had become increasingly difficult and my pain increased. I went to the ER as my symptoms rapidly developed. A needle aspiration was taken and the culture showed staphylococcus bacteria and a white blood cell count of over one hundred thousand. Fortunately, the infection was not moxicylin resistant. Immediately after the lab results were evaluated, I was undergoing arthroscopic surgery to wash the infection out of my knee joint hoping that my ACL autograft had not been compromised by the infection. After the irrigation and evaluation, the surgeon found that my graft had in fact been slightly frayed but reassured me that it functioned properly and the damage was miniscule. A drain tube was put in the joint to monitor the infectious fluid if anymore were to develop. This was removed twenty four hours later for there had been no fluid drainage, which meant there was most likely no need for another wash-out. With these encouraging results, a PICC line I.V. was put in the following day to begin vancomycin antibiotic treatment and I was discharged from the hospital. The course of treatment was estimated to be six weeks. I continued rehabilitation at a strinuious pace in an attempt to regain the lost time due to the second surgery. At four weeks into the antibiotic treatment without any complications or symptoms of infection, I began to develop redness, heat, and spots again-but no fever. Today is two days after that four week mark and the spots seem to be diminishing but there is still redness and heat. My vancomycin trough levels have been perfect and the rest of my blood lab results have only shown improvements. Some medical workers I have talked to suggest that strinuous rehab has caused inflammation and the inflammation is causing the warmth and redness and possibly the spots to reappear. Should I be worried about the infection returning or should I wait until my next checkup with my surgeon and infectious disease doctor to discuss these odd symptoms?My thoughts- The numbers don't add up. If the infection was going to return after the arthroscopic clean out, shouldn't it have returned up to three days after the clean out instead of four weeks? If it is the infection again, shouldn't I have a fever again? Say these new symptoms are due to inflammation, should I take it easy with rehab until consulting my surgeon? Is another needle aspiration necessary right now? Who knows, it might be the safe way to go.Please comment and share your thoughts. I need new opinions. Thanks for your time!
