Abstract

Knee meniscuses are fibrous cartilages that are present to disperse friction in the knee joint between the tibia and femur bones. They work to disperse body weight and reduce friction while moving. Because the condyles of the femur and the tibia converge at one point (which changes as they bend and stretch), the meniscus expand the weight of the body. It is important to describe the mechanical behavior of the meniscus because of its significant role in bearing the load on the knee joint. Research shows Compressive stresses on the menisci have been shown to be a major factor in destructive joint injuries, including osteoarthritis. Anterior cruciate ligament tearcan also have a profound effect on the meniscus. Clinically, meniscus injury is common in patients with a tear cruciate ligament. The main purpose of this study is to determine the stress distribution diagram of internal and external menisci and to evaluate the comparison of healthy meniscus stress and meniscus tearwith the stability of the cruciate ligament and the instability of this ligament. The bone structure of a healthy joint was designed and analyzed in ANSYS program package, and the forces applied to the meniscus under the presence or absence of ACL ligament were evaluated. The results of biomechanical studies showed that tearof the meniscus and the anterior cruciate ligament play an important role in the stability of the meniscus. With the tearof the meniscus and ligament diagram, the distribution of stress and the amount of stress in the meniscus increases, which can be obtained by the interdependence of the meniscus and the surrounding ligaments for normal joint function.
