Meniscal tears usually do not heal on their own, but when the tear is small and the damage is mild, it can be healed through conservative treatment. The central region of the meniscus is not supplied by blood vessels, and its nutrition mainly comes from joint fluid, so it is difficult to heal on its own after a meniscal injury. If the injury is mild, the tear is small and located at the edge of the position, conservative treatment can be used, that is, within 24 hours of the injury, cold compresses to promote vasoconstriction, to achieve the purpose of analgesia and hemostasis. 24 hours later, switch to hot compresses, and through the plaster or brace fixed protection, meniscus injury can gradually heal. If the meniscus is completely torn and the trauma involves the joint level, conservative treatment is not effective and prompt surgical treatment is required. Arthroscopic repair or partial removal of the meniscus can be performed and postoperative knee brace devices are used to avoid premature weight bearing walking. When a meniscus tear occurs, pain in the knee joint is mostly present and patients should seek medical attention as soon as possible to reduce the impact of the meniscus tear on their daily life.
