>If you take the device fresh and something isn't right you can claim it was defective. If it was used for another operation who is to say when something happened to it? There's something on the order of 100,000 ACL tears per year. Even with no reuse, it seems odd that economies of scale can't get that well below $900.
Economies of scale have nothing to do with medical billing in the US. For example, IV bags of saline don't cost $100 in the real world (more like $1).
It's not as simple as insurance alone driving the cost, but having a throat to choke if something goes wrong does contribute to it.
As has been mentioned elsewhere, random overhead is covered in weird places, as well.
