From what I’ve heard and read in the past, in addition to other comments here, there are probably two additional reasons why surgeries aren’t commonly recorded:
Patients probably wouldn’t like knowing how casual a lot of operating rooms are. While you’re unconscious, they’re often playing music in the background and having idle gossip.
Surgeons don’t want an additional element of stress caused by recording and additional regulation that would likely accompany that during situations that are already stressful.
