Maybe this part was a plain old typo?? the word not left out??
[they state that I have (not) had my hardware REMOVED]

Certainly is very confusing & upsetting to be seeing these mistakes by "professionals"

I hope there was a correction notation in your records & on the MRI report that states Hardware IS still there per the doctor & signature.

It would be good to know if the radiologist /tech themselves typed up report or an assistant of some sort.
This really should be corrected one way or another.

Was it a Typo or poor MRI imaging??
Did the hardware show in the MRI images & I assume it would, but maybe not?

[my doctor doublechecked on the hardware and said that it is still there]

did he check the images to verify, or physically checked you, or checked during the surgery for the tear that was not there?

I really would be curious to know how these mistakes came about...
You went thru an unnecessary surgery?? and are they planning to bill you for this?
Something is not right about that.
