Unhappy triad - Medial vs Lateral Meniscus

[Phloston]

I want to get this settled once and for all:

Is the unhappy triad, in terms of the USMLE,

ACL + MCL + medial meniscus, or

ACL + MCL + lateral meniscus ?


It had shocked me, when I had done a question in USMLE Rx about two months ago, to find that the answer was lateral, not medial meniscus.

Even FA, on page 405, says lateral, not medial, meniscus.

However, note the errata for FA says medial, not lateral.

Does anyone have any thoughts on this?

Tangential (bc it's shoulder, not knee), but knowing the basic tests is important. I've seen a question that specifically wanted to you to know "supraspinatus" for empty can test.
