Someone who seemed a bit better informed
Could be a few things - looks like part of one of the other ligaments, is usually damaged doing a 'standard' dissection, plain old 'you see what you think you should see' bias, some combo of all of the above...
And that comment is answered by:
Medicine needs more Masters and PhD students. I'm sure if they had as many students studying the body in extreme detail, like the eleventy billion English majors who write thesis/dissertations on say, Shakespeare, this would've been hammered out decades ago. XD
Which is interesting-- sometimes studying things in extreme detail "just because" (probably because the object of study has high status-- consider early observations of the planets) can pay off big.
The "new ligament discovered" angle gets less impressive (to me, at least) when I read this part:
Their starting point: an 1879 article by a French surgeon that postulated the existence of an additional ligament located on the anterior of the human knee.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
