The Anterior Cruciate Ligament (ACL) is one of the four main ligaments that connects the femur to the tibia. The knee is a hinged joint held together by the lateral collateral (LCL), posterior cruciate (PCL), medial collateral (MCL), and anterior cruciate (ACL) ligaments. The ACL runs diagonally in the knee’s middle and prevents the tibia from sliding out in front of the femur. It also provides rotational stability to the knee. The ACL is one of the commonly injured ligaments of the knee. In fact, ACL injuries are estimated at 200,000 yearly. ACL reconstructions performed yearly are also estimated at 100,000. Understandably, the incidence of ACL injury is generally higher in individuals who engage in high-risk sports like football, basketball, soccer, and skiing which involves a lot of pivoting. At least 50 percent of ACL injuries occur in combination with articular and meniscus damage.
