New Knee Ligament Found... (It wasn't hiding). WTF???

Humans have been studying their own bodies for centuries, piecing together what all the parts are and how they work and interact, but apparently one tiny piece in the human knee has gone undiscovered until now.

Belgian researchers have for the first time described a new ligament in the human knee, termed the anterolateral ligament (ALL).

The researchers conducted in-depth examinations of 41 cadaver knees, and found the new ligament in all but one of them. A French surgeon first postulated its existence in 1879, but it hadn't been proven and fully described until now, said Dr. Steven Claes, an orthopedic surgeon and study co-author at the University of Leuven, Belgium.

"The anatomy we describe is the first precise characterization with pictures and so on, and differs in crucial points from the rather vague descriptions from the past," Claes told LiveScience. "The uniqueness about our work is not only the fact that we identified this enigmatic structure for once and for all, but we are also the first to identify its function." The researchers presented their new work this March at the American Academy of Orthopaedic Surgeons meeting in Chicago.

yeah I read this the other day.

short tiny muscles surround it so it was pretty hard to discern from the surrounding tissue.

They will better understand knee surgery now
