Winter exercise can improve the body's ability to fight disease. However, because the cold weather is easy to lead to muscle and muscle tension, such as improper stretching, it is easy to lead to injury.

According to the official website of the Beijing Emergency Medical Center, 120 Beijing Emergency Medical Center recently treated a student suspected of lower limb trauma during school exercise.

On November 11, Beijing West Emergency Center station received a task, a school student suspected of lower limb trauma during school exercise. Emergency doctors rushed to the scene to check and ask the patient after the diagnosis of patellar dislocation, and then successfully implemented knee joint reduction for the patient, and then the patient could stand and walk.

Here, 120 Beijing Emergency Center reminds everyone that knee dislocation (patella dislocation) is a serious injury, the need to clear the patient's dislocation, after professional doctors judge that there is no obvious important neurovascular injury, it is recommended to carry out knee joint reduction as soon as possible, is a very favorable method for the late functional recovery of the knee joint and trauma recovery.

Therefore, once the knee dislocation occurs, it is necessary to seek medical attention in a timely manner, get a professional diagnosis of the doctor in a timely manner, and then be dealt with in a timely and effective manner by a professional doctor, so as to avoid serious complications due to the knee dislocation for too long, so that the function of the knee joint is impaired in the later stage.

What are the causes of knee dislocation (patella dislocation)?

120 According to the Beijing Emergency Center, there are many reasons for knee dislocation (patella dislocation), including traumatic knee dislocation and congenital knee dislocation; Traumatic knee dislocation, as the name suggests, is a fall or trauma that leads to abnormal development of the bone structure around the knee joint, or an imbalance of the soft tissue structure that leads to knee dislocation.

Congenital knee dislocation, mainly related to the internal and external knee inversion, as well as congenital abnormalities of the tendons around the knee joint, or congenital abnormalities of the ligament tissue, or abnormal bone structure development, resulting in patellar dislocation.

How to prevent knee dislocation (patella dislocation)?

120 Beijing Emergency Center reminds that the most important thing is to strengthen sports protection to prevent trauma. Adequate preparation should be made before physical exercise to prevent injury, and children should avoid pulling. Adequate warm-up activities before exercise, improve the excitability, response ability and resistance of muscle tissue, and gradually increase the degree of resistance, is helpful to reduce joint dislocation.

Plus, roll with the flow. Some self-protection measures for professional athletes when they fall are also worth learning from ordinary people. For example, when a volleyball player dives to save a ball or a soccer player falls after a collision, they will roll along with the momentum, and change the direct hand support to the palm support, and gradually complete the roll by the elbow and shoulder. Sometimes, athletes roll on the ground for several laps, as if they are heavily stressed, but can immediately stand up and continue to fight, because the huge impact of their landing is shared by multiple parts of the body during the roll, so that it does not concentrate in one place and cause serious damage.

It should also be noted that when exercising outdoors in the cold, warm-up exercises are indispensable, especially when running and jumping are needed. If accidentally caused accidental injury, easily do not move the patient, timely call 120 emergency phone for help. (Reporter Sun Hongli)
