Women are more prone to ACL injury. Women are twice as likely to tear their ACLs than men are — in fact, some research puts the risk much higher, at eight times the risk men have. There are a ...
Most ACL tears are a result of a non-contact mechanism such as a sudden change in a direction causing the knee to rotate inward. As the knee rotates inward, additional strain is placed on the ACL, since the femur and tibia, which are the two bones that articulate together forming the knee joint, move in opposite directions, causing the ACL to tear.
There are around 200,000 ACL tears each year in the United States. ACL tears newly occur in about 69 per 100,000 per year with rates in males of 82 per 100,000 and females of 59 per 100,000. [67] When breaking down rates based on age and sex, females between the ages of 14 and 18 had the highest rates of injury with 227.6 per 100,000.
ACL injuries can be categorized into groups- contact and non-contact based on the nature of the injury [6] Contact injuries occur when a person or object come into contact with the knee causing the ligament to tear. However, non-contact tears typically occur during the following movements: decelerating, cutting, or landing from a jump.
Treatment of the unhappy triad usually requires surgery. An ACL surgery is common and the meniscus can be treated during the surgery as well. The MCL is rehabilitated through time and immobilization. Physical therapy after the surgery and the use of a knee brace help speed up the healing process. A typical surgery for a blown knee includes:
The cruciate ligaments of the knee are the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). These ligaments are two strong, rounded bands that extend from the head of the tibia to the intercondyloid notch of the femur. The ACL is lateral and the PCL is medial. They cross each other like the limbs of an X.
Surgery is usually required in complete tears of the ligament. Surgery usually takes place after a few weeks, in order to allow swelling to decrease and regular motion to return to the knee. A procedure called ligament reconstruction is used to replace the torn PCL with a new ligament, which is usually a graft taken from the hamstring or ...
