Anterior cruciate ligament injury

The knee joint is composed of 3 parts of bone: thighbone (Distal femur), shinbone (Proximal tibia and kneecap (Patella). There are the smooth white tissue (articular cartilage) which covered all 3 bones and 2 wedge-shaped pieces of fibrocartilage (Meniscus) between the shinbone and thighbone that act as a shock-absorber and load transmission


The anterior cruciate ligament (ACL) is the ligament that lie inside the knee joint. It attached between the thighbone and shinbone and run obliquely in the joint. The function of the ACL is stabilizing the knee joint by controlled anterior translation of the shinbone relative to the thighbone and controlled the rotation of the knee when you quickly turn around or change direction especially during the sport activity.
