In case you've missed the anatomy news of the week, if not the year at the very least, researchers have apparently discovered a ligament in the knee that was described in 19th century but not noted since then.
Strange to think that a ligament like this could go unnoticed for so long, what with all the technology we've developed over the years and the number of dissections that must have taken place in the intervening years. What is interesting is whether there is a relationship between ACL damage for example and this ligament. One wonders what role it plays in stabilising the knee. Perhaps it works with the LCL given it's proximity, but we shall have to wait and see what the experts discover.
