Minimally invasive treatment of meniscal injuries is the arthroscopic surgical treatment of meniscal injuries. Minimally invasive treatment of the meniscus is the result of the development of modern arthroscopic techniques. Arthroscopic surgical treatment of the meniscus involves making two 1-cm incisions at the anterior knee eye, inserting the arthroscope into the joint cavity for direct visualization, probing the extent of the meniscal injury, the site of the meniscal injury, and the type of injury, and treating the meniscal injury based on the results of the intraoperative exploration. In young people, if the meniscus injury is fresh, the lateral longitudinal tear can be sutured to restore the integrity of the meniscus and restore the function of the meniscus in most cases. If the meniscal injury is severe and suturing is not possible or if the patient is over 60 years old, partial meniscectomy can be performed to relieve the symptoms of the meniscus injury. Minimally invasive treatment of meniscus injuries is the gold standard of modern knee surgery, so patients with meniscus injuries should undergo minimally invasive surgical treatment.
