After meniscus repair surgery should be based on the degree of the patient’s condition and general condition to decide the time to go down to the ground, in general, 4 to 6 weeks after surgery can help crutches down to the ground for partial weight-bearing activities, and gradually transition to full weight-bearing activities. Meniscus injury repair is a kind of surgical treatment for meniscus injury. For patients with severe meniscus tear injury, if conservative treatment is ineffective, most of them need meniscus repair to maximize the preservation of meniscus tissue to maintain its main physiological function. After meniscus repair, joint activities need to be carried out as early as possible. Generally, passive knee extension and flexion exercises can be carried out on the 2nd day after surgery to avoid knee stiffness, and the patient can get down to the ground after 4 weeks, and carry out partial weight-bearing activities by holding the crutches, and the affected limbs can be fully weight-bearing after 6 weeks. After meniscus repair patients should be under the guidance of a professional physician to carry out activities on the ground, to avoid prematurely going down to the ground, which is not conducive to wound healing.
