Lindsay Robinson, a 16-year-old girls high school football player, tore the anterior cruciate ligament (ACL) from a football game. Interestingly, she was not the only one who hurt the ACL, but some teammates were ripping the same ligament during the football season. Lephart (2002) found that women participating in physical activity were more susceptible to ACL damage than men who participated in the same physical activity (described in Ogden, 2002). According to "ACL Injury Prevention" (2004), the number of violations of women's ACL has increased in the past decade.
Recently, the American Journal of Sports Medicine reported that if athletes follow a specific exercise program "prevention of injury and improvement of performance", it is possible to greatly reduce the ACL damage rate of female athletes, especially contactless ACL damage I can do it. PEP) is planned before practice and competition. The PEP project was designed in 1999 by Santa Monica Orthopedic Surgery and an expert team of 19 non-profit organizations of the Sports Medicine Research Foundation. In the case of special equipment, it can be completed within 30 minutes.
Gender plays a complex role in the risk of ACL damage. In men there are many men who participate in physical activity, so ACL injuries are more common, but when comparing male and female university sports, women have a 2- to 8-fold probability of developing ACL injury than men It becomes high. Men with large Q angles increase the biomechanical pressure of ACL. The cross section of the negative ACL is small, the destructive tensile load is reduced by 8%, and the elastic modulus is reduced by 22%. These factors are associated with a higher injury rate, coupled with an increase in the sympathetic knee joint moment of aura at the time of landing of the leg. Changes in hormone receptors for ACL fibroblasts and knee joint relaxation during the menstrual cycle have been demonstrated; however, the effects of the menstrual cycle on the rate of ACL injury have not been explicitly stated.
As we all know, girls' athletes are at high risk of ACL tearing when participating in competitive sports. Unfortunately, it is not clear why women are susceptible to ACL damage. Some suggestions are biomechanics, strength and hormone related. In fact, this may be one of three factors. Many patients with ACL tears begin to feel better within days or weeks of ACL injury. These people may feel that the knees are normal again, as the swelling has started to settle. But this is when your knee is unstable and it gives a way that the problem may start or worsen
