Hello - I am sorry to hear this has happened again. I know how painful it is after only a single dislocation - but so many - ow!
I hade my hips replaces some years ago, and in 2012, the balls, cups and liners had to be removed and replaced because they were recalled, failing and had given me heavy metal poisoning.

The dislocation occurred one week after revision surgery, while I was sitting in a chair with my leg elevated. My surgeon immediately recognized, upon sedated examination, that the ball and liner were not the best fit for my situation, and replaced them with larger and somehow different parts. The end result was no more dislocations and complete healing, which took longer because muscles and ligaments were damaged by the event and extra surgery. So I had a lot of land and water PT and have been free of pain and dislocation for 8 years. The only "effect" of note is that radiologists always comment on any x-ray of the area "patient has bilateral hip implants of differing size and positioning" or something similar.

There is hope for full recovery!
Sue
