My wife had a bilateral hip replacement in 2011 at which time the nerve in her right leg got compressed , therefore, leg did not work and had to wear a mobilizer at All time when mobil, wife comes out of surgery Black & Blue from Head to Toe and I mean everywhere. I wanted to take pictures but wife declined . Goes to rehab, doctor omits order, nurse goes to give wife a shower, falls. Dr called it an assisted fall. 9 months later, left nerve starts to work, Dr says right hip was fractured, needs a revision( 2012. 2018 revision required on left hip due to Cobalt / Chromium poisoning. 2022 revision on right hip due to staph infection along with Cobalt / Chromium poisoning, whole implant removed and medicated spacer implant for 9 weeks, then a new implant. Now, where they kept placing epidural, degenerative disc disease, impacts mobility. Long story short, yes, revisions can and do happen. I recommend that you do a lot of research on a reputable Surgeon from the start and not a teaching hospital!
