Related Content of Knee Joint Injuries
Knee joint injuries are divided into acute and chronic injuries. Acute injuries include muscle strain, meniscus injury, cartilage injury, and ligament injury (anterior and posterior cruciate ligaments, as well as internal and external collateral ligament injuries). Chronic injuries include: chronic injury transformed from acute injury, patellar tendon end disease, patellar cartilage, and traumatic arthritis. The knee joint, as a highly mobile joint, is easy to injure during exercise. Acute injury may damage muscles, cartilage, and ligaments. For children, acute injury may turn into chronic injury if it is not treated promptly and effectively. Knee ligament injury is also known as knee ligament injury. It is commonly seen in sports injuries, mainly manifested as knee joint pain, swelling, and limited knee joint movement. The ligament in a knee joint ligament injury refers to the ligaments surrounding the knee joint, such as the anterior cruciate ligament, medial collateral ligament, lateral collateral ligament, posterior cruciate ligament, medial patellar ligament, and lateral patellar ligament. Knee joint injuries exhibit early histological fibrosis. After a knee ligament injury, conservative or surgical treatment is required based on the severity of the injury. Tendons are similar to ligaments, connecting muscle fibers and musculoskeletal structures. This type of replacement structure is also known as a graft, which is a ligament that medical staff can refer to when removing a part of the patient's pathological knee joint. After the surgery, the patient will smoothly undergo another course of rehabilitation training. Severe injury in sports and excessive movement of knee joint are the main reasons for knee joint injuries. The common causes of knee joint sports injuries in children include: sprains, falls, bruises, abrasions, impact injuries, and other violent injuries that are more prone to occur in highly adversarial activities, such as basketball and football, long term participation in repetitive jumping exercises, or frequent mountain climbing, building climbing, and squatting, and incorrect exercise methods and lack of reasonable exercise protection. Children should be extra careful in the process of antagonistic sports, and exercise that is harmful to the knee joint should be moderate. However, if the knee joint has been injured and feels unwell, it is likely that the knee joint injury has occurred and medical attention should be sought in a timely manner. The pressure on the knee joint in different postures is shown in Figure 1.

The main symptoms of knee joint sports injuries in children are obvious pain, swelling, and limited mobility immediately after injury. When taking X-rays at the hospital, it may be difficult to accurately diagnose meniscus or cruciate ligament injuries due to joint swelling. For months or years, there may still be discomfort such as joint weakness, pain, and interlocking, and even no obvious discomfort. Therefore, it is necessary to seek further consultation with a sports injury specialist to make a clear diagnosis. Chronic strain may cause pain when walking, squatting, or jumping on a flat road and may also be manifested as limited joint movement, swelling, interlocking, softness, and fatigue.
