Crunching when bending the knee does not determine whether there is a possibility of continued growth, and needs to be analyzed according to the patient’s age and whether the epiphysis is closed. The creaking sound when bending the knee is a kind of popping sound of the knee joint, which is not directly related to whether the patient can grow taller or not. To determine whether children and adolescents can still grow taller, we can refer to age, whether the epiphysis is closed and other factors. The epiphysis has not yet closed, can continue to grow taller, usually pay attention to strengthen the diet and nutrition, appropriate exercise, maintain sufficient sleep time. If the knee creaks when bending, accompanied by symptoms of pain or limited movement of the knee joint, it is considered to be related to the internal lesions of the knee joint, such as meniscus or cruciate ligament injuries, inflammation, etc. The patient should consult an orthopedic doctor as soon as possible. You need to go to the orthopedic department as soon as possible for examination, to clarify the specific cause of the disease, and then under the guidance of a professional physician targeted treatment, to prevent the later impact on the sports function of the knee joint.
