New ligament discovered in knee

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. more
