Second-degree meniscus injury requires at least one month to walk, because the second-degree injury has caused the meniscus to rupture, although it has not reached the edge of the joint, but because the meniscus contains less blood flow, so the recovery is slower, most of the conservative treatment has a chance to heal. If the injury site is in the red zone of the meniscus body, because of the rich blood flow here, so the healing is faster, about 1 month can be healed, the pain disappears after the patient can support the crutches down part of the weight-bearing. However, if the injury site is in the anterior or posterior corner of the meniscus, the blood flow here is poorer, so the healing is also slower, and it takes about 6-8 weeks to be able to walk on the ground. Therefore, the resting time of second degree meniscus injury should be evaluated according to the type of meniscus injury and the specific site, and the patient should not get off the ground too early, because if he/she gets off the ground too early, it is not conducive to the recovery of the meniscus and may leave sequelae in the future.
