RELATIVE STABILITY PROVIDED BY THE MEDIAL MENISCUS AND CRUCIATE LIGAMENTS AT HIGH AND LOW AXIAL COMPRESSIONS

摘要

The ACL, PCL and medial meniscus are important stabilizing structures in the knee joint. Investigating what role they play in stability and mobility is essential to understanding how degeneration might occur in the knee. The purpose of this study was to investigate how the ACL, PCL, and medial meniscus respond to compression, shear, and torque. A custom made testing machine was used to simulate various kinematic positions. Results indicated that the medial meniscus, ACL and PCL all play a role in stabilizing the joint regardless of the compression applied.
