Most PE-owned companies do well. Do a paper search for median employment N years afterwards [1], net indebtedness 5+ years post, et cetera.
The problem is outcomes are negatively correlated with transaction size, so the more noticeable a deal the more likely it goes wrong. (There are also a few pirates in suits who go shockingly unpunished. But judging the cohort by them would be like judging tech by Chamath.)

I haven't been in that loop since before covid, but last I heard they were running at a loss for years because they couldn't keep staff. The conditions (and pay) were abhorrent. They also really, really liked to buy entire practices from the most experienced doctors. The practice got absorbed and died quietly while the doctor would very understandably retire early or move far away.
So, yes, they've maintained market share. But only by virtue of being a natural monopoly.
By design.
Look up Certificates of Need. They are an application a prospective new hospital needs before breaking ground, to make sure an area isn’t “overserved” by hospitals (i.e. protecting profits).
Certificates of Need were lobbied for by … drumroll … hospital owners.
Sales were already going down and they responded by raising prices every time to make up for the lost revenue. The market itself was shrinking less than market share being lost.
Another product line I was less involved in pivoted direction and I guess is still doing OK.
