I had 4 replacements over the space of 38 years. (Beginning at age 26). The first three I simply wore out. The 4th was in December 2006. Seven years later in 2013 I went septic and nearly died. The hip was infected as well as all around the femur. After 6 months of picc lines and daily IV antibiotics the prosthesis was removed. I remained on IV antibiotics another 6 months when it was discovered the MRSA had mutated into a rare form called VISA. Yes, I've heard all the jokes. New drugs were tried and I finally had good blood markers in 2017. The surgeon who had promised replacement number 5 reneiged on the promise. A second opinion was that the infection could never be claimed 100% gone and any surgery is highly dangerous. I now have a third surgeon who also refuses to do another replacement, but is working with me on walking on the leg with assistance. I applaud your determination and I wish you luck.
