In 1879, a French gynecologist / knee expert
suggested that a tiny but very important body part existed. No one seemed to be in any hurry to test his hypothesis, although there was some desultory interest shown in the 1970s and 2000s. This Tuesday, two Belgian researchers (Steven Claes and Johan Bellemans) confirmed that the anterolateral ligament (ALL) exists and that about 97% of us have it.
.) "The doctors wanted to know why some patients with ACL tears suffered from pivot shifts, or knee collapses, even after successful reconstructive surgeries. ... Patients with ACL tears were likely suffering knee collapses because of ALL injuries."How could this be missed so long? Yes, it is small, but it’s not really that much smaller than the Lateral Collateral Ligament also known as the LCL, at least according to the photographs, and that ligament is a well-known troublemaker. ... However, doctors themselves are quite cavalier about what appears to be a massive medical oversight. University of British Columbia professor Dr. Wayne Vogl says the ligament has continued to be missed “because of all the other stuff that is there.” Alrighty then.

argues that this is more of a "rediscovery" than a new discovery. “We’ve known for years that a thickening around the area where the ALL is located has a role in knee stability,” he said. “While I don’t think this is necessarily a breakthrough, I think it’s a good reminder that we need to refocus some attention on ACLs that don’t respond well to surgery.”
