Rupture of cruciate ligament of knee

If the cruciate ligament of the knee joint is ruptured, it is a relatively serious condition and must be treated urgently. Do not delay the treatment of your illness. Only early treatment can avoid any root of disease in the joint. Otherwise, it will cause complications, which will prolong the treatment time and increase the difficulty of treatment.

(2) Gender: The average body fat content of yellow men is 13% of their body weight, while that of women is as high as 23%. Women have relatively less muscle content than men, so the incidence of sports injuries to the knee joint is higher in women than in men. In addition, female hormones are secreted cyclically. If the menstruation is disordered, it will cause low estrogen secretion, which is known to be one of the causes of fatigue fractures.

(3) Physique and skills: People with high body fat and heavy weight will have less muscle development, so their body flexibility and endurance are correspondingly poorer, making them more susceptible to injury. Especially when resisting violence that causes trauma, heavy people are at a disadvantage. The strength ratio of the flexor to extensor muscles is a very important factor that can lead to muscle tears in many cases. Exercisers with poor technique are also more susceptible to injury.

(4) Others: In the case of poor physical condition (chronic fatigue, anemia, colds, dysmenorrhea, lack of sleep, etc.), lack of keen judgment and quick and accurate protective response to unexpected events may lead to sports injuries.

2. Psychological quality:

When playing high-impact sports (such as football), the risk of injury increases if attention is not focused or the focus is not sustained for long enough. People who are emotionally unstable, easily irritable, eager for quick results, or who are hesitant during exercise due to fear, panic or shyness are prone to sports injuries.

External reasons:

(1) Qualitative factors: Some participants choose inappropriate sports without considering their own conditions, which results in an increased incidence of injuries. For example, older people who play football or try to use frog jumps to strengthen the waist and leg muscles may suffer knee injuries; when doing flexibility exercises, excessive passive training of ligaments and muscles may cause muscle avulsion. Therefore, physical exercise should be scientific and you should choose sports that are suitable for your physical condition.

(2) Quantity factors: Exercising for too long, in too much volume, or at too high a frequency can easily lead to overtraining, which is one of the main causes of sports injuries. Overtraining is caused by the exerciser being subjected to too much load, so that the body has not fully recovered. Its symptoms include: increased resting heart rate, increased blood pressure, poor sleep (insomnia, nightmares, easy awakening, etc.), decreased appetite, weight loss, no desire to train, irritability, irritability, decreased memory, etc. If overtraining is not corrected in time, it will reduce the body's immune function, thus increasing the incidence of infection and chronic fatigue.
