I've had two revisions due to infection. The first was performed over 10 years after my initial THR, and seemed to have been relatively routine. Once that hip became infected, the second revision was a bit more difficult. My orthopedic surgeon had a difficult time removing the implant, since the bone had grown into it, as was intended. Removing the prosthesis caused damage to my femur and my surgeon felt he was not up to the task to install another prosthesis, especially with the chronic infection. I lived with a spacer for about a year until I had outside approval from my HMO to see a surgeon specializing in reconstructive and oncology surgery. Two years out, so far, so good, but I still live with chronic infection for which I have a nightly antibiotic infusion.
So, short answer, after multiple surgeries, none are like the other. Every one is different. I still feel like I'm overcoming the deconditioning I experienced while I had the space and in recovery. Ask questions - especially about risk of infection.
