Reconstruction of the anterior cruciate ligament (ACL) is a
surgery designed to restore knee movement and strength after
your ligament has been torn. The torn ligament must be removed
and replaced with another ligament from your body or with tissue
from a cadaver. The knee is a hinge joint where the femur
(thighbone) meets the tibia (shinbone). This important joint is
held together by four ligaments (fibrous tissues) that connect
the bones to one another: - anterior cruciate ligament (ACL) -
medial collateral ligament (MCL) - lateral collateral ligament
(LCL) - posterior cruciate ligament (PCL) An ACL tear is one of
the most common knee injuries, especially among people who
participate in high-impact sports like basketball, football,
soccer, skiing, and hockey. The majority of those injuries—70
percent—occur without impact to another player, according to the
American Academy of Orthopaedic Surgeons (AAOS). They most often
occur when an athlete twists or pivots during play. There are
about 200,000 ACL injuries
