Knee hyperextension, also known as knee hyperextension or knee anteversion, is mainly related to elevated muscle tone, structural changes in the knee joint, or insufficient muscle strength, and can be corrected by wearing orthotics, sports rehabilitation, or surgical treatment according to the condition. 1. Wearing orthotics: If the tension of the triceps muscle is elevated, it is usually easy to cause knee hyperextension, and can be corrected by wearing orthotics or combining with exercise stretching. 2. Sports rehabilitation: If the muscle strength of the front side of the thigh is insufficient, such as the quadriceps muscle strength decreases, it is easy to cause the phenomenon of knee hyperextension, which needs to be corrected through sports rehabilitation to improve the strength of the muscles around the thigh, and to strengthen the stability of the knee joint. 3. Surgery: If the knee joint has structural changes, it will easily lead to functional problems of the knee joint, resulting in knee hyperextension. If the situation is more serious, we can’t rule out the need for surgical treatment, such as knee arthroscopy repair. In daily life, pay attention to maintain good posture, do not long time weight-bearing exercise. Before the knee joint is fully corrected, reduce the load on the knee joint as much as possible to prevent the symptoms from worsening and affecting the recovery.
