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.
I'm more impressed, actually, in terms of the unevenness of progress - it took ~134 years to confirm his postulate? It's not like corpses were unavailable for dissection in 1879.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
