Dr. Johnson describes the anterior cruciate ligament (ACL).
Hi, I am Dr. Darren Johnson from the University of Kentucky where I currently serve as the professor and Chairman of Orthopedic Surgery and the Director of Sports Medicine.
So the ACL, or the anterior cruciate ligament, is a soft tissue structure that lives inside your knee, and it connects the thighbone or the femur to your shinbone, which is called the tibia. And that ligament helps prevent those two bones rotating on each other which is abnormal. So if you don’t have that ligament, if you tear that ligament and you do not have it fixed, then what happens is the two bones, your thighbone and your shinbone, are going to abnormally rotate on each other during certain activities.
