Case Study: University of Missouri improves knee biomechanics research with Hexagon Adams

Adams simulations help diagnose knee problems

The University of Missouri sought to better understand the complex biomechanics of the human knee, specifically the role of the menisci in stability and force distribution. To advance beyond traditional analysis methods, their researchers needed a powerful dynamics simulation tool capable of modeling the entire knee joint and replicating muscle-driven motion. They partnered with Hexagon and utilized its Adams multibody dynamics software to address this challenge.

Hexagon's Adams solution enabled the creation of a highly detailed and accurate musculoskeletal model of the knee by integrating motion capture, MRI, and force plate data. This implementation, which leveraged Adams' integration with Simulink, accurately predicted internal contact forces and ground reaction forces with over 90% correlation to physical results. The research successfully quantified how loosened meniscal ligaments lead to a loss of force transfer, increasing the potential for joint damage. These findings provide critical insights that will help improve the diagnosis of knee problems and the development of surgical interventions.
