A. An anterior cruciate ligament, or ACL, injury is a tear in one of the knee ligaments that joins the upper leg bone with the lower leg bone.The ACL keeps the knee stable.our ACL can be injured if your knee joint is bent backward, twisted, or bent side to side. The chance of injury is higher if more than one of these movements occurs at the same time. Contact (being hit by another person or object) also can cause an ACL injury. An ACL injury often occurs during sports.
MCL tears rarely are isolated. More commonly, they are associated with other soft tissue injuries of the knee, such as anterior cruciate ligament (ACL) tears and medial meniscal tears (O'Donoghue's unhappy triad). Of complete MCL tears, 73% are associated with additional significant knee injuries, usually an ACL tear.CL tears rarely are isolated.
