A horizontal tear of the meniscus body can only reflect the location and direction of the tear, but not the severity. The meniscus is a round or “C” shaped fibrocartilage located in the knee joint. When the knee joint is stimulated by an external force that generates grinding forces, it can lead to a meniscus tear. There are five types of meniscus tears: longitudinal, horizontal, diagonal, transverse, and variant. A horizontal meniscus tear indicates a rupture in the body of the meniscus, and the type of rupture is horizontal. The severity of the disease needs to be determined by the degree of meniscus tear, clinical symptoms, physical examination and auxiliary examination. If you have been diagnosed with a horizontal tear of the meniscus, it is recommended that you complete the relevant examinations to determine the extent of the meniscus tear, and follow the doctor’s instructions for standardized treatment as soon as possible in order to reduce the adverse effects of the disease.
