The Anterior Cruciate Ligament consists of two separate and functionally distinct anatomic bundles (the anteromedial (AM) and the posterolateral (PL) bundles),these bundles demonstrate clearly different biomechanical properties and tensioning patterns with varying degrees of knee flexion, the AM and PL bundles comprise relatively equal proportions of the overall ligament insertion on both the femoral and tibial footprints, Both bundles provide significant contributes to the stability of the knee in response to combined rotatory loads.An anterior cruciate ligament (ACL) rupture is one of the most common knee injuries in sports. Unlike many tendons and ligaments, a mid-substance ACL tear cannot heal and the manifestation is moderate to severe disability with ”giving way” episodes in activities of daily living, especially during sporting activities, further, it can cause injuries to other soft tissues in and around the knee, particularly the menisci, and lead to early onset osteoarthritis.
