Although these theories have not been proven, agility training and muscle strengthening seem to be appropriate measures women can take to help prevent injury. Hormonal differences focus on estrogen in the female body and its effect on ligament laxity and knee looseness. Women tend to change direction and land from jumps in a more erect stance, and this can put the ACL under strain. Neuromuscular differences in the timing of muscle activation and how women perform risky movements may increase the female's vulnerability to ACL injury. The mechanics of the woman's body, with the pelvis creating a larger angle from hip to knee, may make the knee more prone to injury. Other differences make the female a more likely candidate for ACL trouble than her male counterpart. The male's lower percentage of body fat and greater muscle mass give the male an advantage in muscular strength to protect the ACL. The ACL and the notch (illustration) on the femur that it sits in are smaller in women than in men, but that may just be because women are smaller than men. Why do females seem more likely to injure the ACL when they play the same sports as males? Many studies are looking at the physical differences between the sexes for answers to this question. Competitive female soccer and basketball players have 3-5 times higher risk of ACL injury than their male counterparts. A hit that results in the tibia being driven forward, the femur being driven backward, or the knee joint being severely hyperextended may result in damage to the ACL.įemales appear to be more at risk for ACL injuries. It can be damaged along with the medial collateral ligament (MCL) when the knee is struck from the outside. The ACL is also very susceptible to injury in contact sports. The stiffness and height of the ski boot cause the forces to be transferred up the leg to the vulnerable knee joint. The length of the ski adds more force to the twisting motion.

Skiing has additional risk factors that increase the chances of ACL injury. These sports require movements that cause the femur to pivot on the tibia. Basketball, skiing, and football are examples of sports in which a high number of ACL injuries occur. Sports in which the foot is planted, the knee is bent, and change in direction is emphasized are commonly associated with ACL injuries. The fibers of the ligament are completely torn. Grade III - This is the most severe ACL injury. Grade II - Trauma to the ligament is more severe. Grade I - Trauma to the ligament is relatively minor. The three grades of ACL injury range from mild to severe. It also helps prevent overstraightening and over-rotation of the femur on the tibia.Īn ACL injury usually occurs when the knee is sharply twisted or extended beyond its normal range of motion.

The ACL prevents the tibia from sliding too far forward underneath the femur. This ligament runs from the top surface of the tibia diagonally into the large notch at the end of the femur. Self-controlled learning : Empowering the patient with some control over exercises and feedback during rehabilitation can greatly facilitate motor learning.Ĭontextual interference : Interference during practice can lead to higher skills learning, yielding better retention and transfer performance.The anterior cruciate ligament is one of two ligaments inside the knee joint (the other is the PCL ). By performing a variety of motor patterns, the patient is able to find motor solutions that works for them, within the context of their own limitations, skills and environment. Implicit learning : Rather than following explicit instructions, implicit learning uses visual imagery to help the athlete “feel” each movement, prompting a more automatic motor response.ĭifferential learning : Each patient is unique, with distinct strengths and limitations. EFA directs the patient’s attention to movements in the environment, to promote automatic processes, resulting in more efficient movement and greater quadriceps voluntary activation.
