Function, Injury, and Treatment for Meniscus

Abstract

The meniscus is considered a vital structure for maintaining normal functions and perennial health of the knee joint. This study focuses on the meniscus and discusses its function, injuries and the corresponding treatments. Results show that two menisci are located in the knee joint- medial and lateral meniscus, which are different in shape but work together to provide specific functions. The main functions of the meniscus include load sharing, shock absorption, stability, joint lubrication and nutrition. Meniscal injuries include vertical longitudinal, radial, horizontal (cleavage), degenerative (complex), and bucket-handle tears, all of which can cause serious knee morbidity. There are different symptoms of meniscus damage, and the severity of the damage can be identified from the symptoms. Once the meniscus injury is found, conservative or surgical treatment should be carried out immediately. Conservative treatments generally include massage, acupuncture, and slight movement, as well as drug treatment. Surgical treatments include meniscus suture, partial meniscectomy, and meniscectomy. If it is not treated in time, the meniscus could cause irreversible damage and a series of sequelae.
