Uncertainty is so hard - especially when going into the "unknown" like this.
I am a 5 time hip replacement - but fortunately never had a bad infection, nor faced removal. There is no doubt that living without the hardware will be difficult. I have however had Mycobacterium Intracellulare (aka MAC) in my lungs, and it is difficult to treat. The drugs are awful, but if they remove your hardware, will they be able to place an in vitro antibiotic pump? Have you been seen also by an infectious disease specialist?

As for recovery, I do not know the path - it varies based on how far infection has invaded. Some surgeons use spacers during recovery - do you know if this is the plan? These allow some limited mobility -typically with a walker - for previously active people.

I wish you well as you go forward - there are a number of people on this forum living without a hip joint - you can find them here:
