Whoa, Skygirl, infections are scary! I wish I had a good referral for you, but I respond because my DH just has been dealing with a bone infection stemming from a stroke last year. There is a highly thought of infectious disease specialist here in Eugene OR, at PeaceHealth Riverbend, named Brenda Ormsher. The docs Dan saw in the ER were saying he would lose the toe the next day, but they'd try a round of antibiotics over night in case that would help. When the surgeon returned in the morning, Dr. Ormsher was already in the room and she waved him away, saying she could deal with this; the toe was staying! They all deferred to her and she has been correct. His infection is nearly gone now, 2 months later. I do not know if she has lots of experience with implants and replacement knees, but there are lots of them done there, however it is not listed on the list of their treated conditions. She is not in northern CA however! She is also on the staff of the hyperbaric health center at Riverbend, too. I'll follow your progress here and will send you healing energy as well!
