Meniscal white zone injuries can be treated conservatively and surgically, among others, depending on the circumstances. The meniscus is divided into white zone, red zone and white-red zone according to blood supply. The white zone has almost no blood supply, the red zone has a rich blood supply, and the white-red zone has a blood supply between the two. Due to the poor blood supply of the white zone, healing is extremely difficult, and if surgical repair is performed, healing is also more difficult. 1. Conservative treatment: If the injury is mild, the sports requirement is not high, the pain and activity limitation are not obvious, conservative treatment can be chosen, such as joint braking, avoiding strenuous over-flexion or over-extension and other sports, and physical therapy such as hot compresses and infrared irradiation can also be carried out. 2. Surgery: Because of the poor blood supply in this area, healing is difficult, so the common surgical procedure is arthroscopic partial meniscectomy. The operation is performed through endoscopic entry into the knee joint, revealing the diseased meniscus, removing the diseased part of the meniscus through special instruments, and shaping the meniscus to make the remaining meniscus conform to the anatomical relationship as much as possible and stabilize it after the resection. Meniscus injury is a common injury in clinic, once occurred, should go to the hospital in time, under the guidance of professional doctors for diagnosis and treatment.
