Welcome to the group. I am not familiar with this specific hip, but it sounds like an unusually complex procedure...The typical problem with MOM implants is the friction between the metal acetabular cup and the femoral head so only those are replaced without disturbing the stem.
That's how my revisions, and those of several others I know weer done.

What I would do is to start making calls to see who specializes in revisions near you. Or contact a hospital with a ,large orthopedic surgery practice - the local trauma center is a good place to start.
Let us know if you need help finding somewhere.
