New ligament discovered in knee, Belgian surgeons say

Today's post is shared from the bbc.com

The anterolateral ligament (ALL) may hold the key to common knee injuries, researchers say
Two knee surgeons in Belgium say they have identified a previously unfamiliar ligament in the human knee.
Writing in the Journal of Anatomy, they suggest the fibrous band could play a part in one of the most common sports injuries worldwide.

Despite glimpses of the ligament in medical history, this is the first time its structure and purpose have been so clearly established, they say.
But experts say more studies are needed to prove its relevance to knee surgery.
Four main ligaments - or thick fibrous bands - surround the knee joint, criss-crossing between the upper and lower leg bones to provide stability and prevent excessive movement of our limbs.
But the anatomy of the knee remains complex, and several international groups have been exploring the less-defined structures of the joint for some time.
The notion of this particular ligament was first made by French surgeon Paul Segond in 1879 but it has evaded definitive surgical classification for many years.
'Extensive search'
Now building on the work of other surgeons, Dr Claes and Professor Johan Bellemans of the University Hospitals of Leuven, Belgium, say they have closely mapped the band which runs from the outer side of the thigh bone to the shin bone.
And they say this anterolateral ligament could play an...
