Advancing knee joint modeling towards clinical use

Join us to learn more about new advancements in knee joint modeling. We will present a novel moving-axis knee joint and demonstrate how to implement your own user-defined knee joint into the full body model.

Musculoskeletal knee joint models can range from simple generic (hinge) to complex subject-specific (multi-body contact) depending on their generic qualities and computational time. Selecting a level of complexity depends on the research question being asked and how realistic the knee kinematics need to be. Studies that require realistic kinematics may include: investigating pathologies (i.e. KOA) or designing surgical implants to best restore healthy biomechanics.

This webcast first presents the development and evaluation of subject-specific moving-axis tibiofemoral joint models. This joint model is based on two tibiofemoral flexion angles, at about 0 and 90 degrees, and the articulation modeled such that the joint axis moves linearly between these two positions as a function of flexion. The novelty behind the moving-axis is that it not only provides more realistic joint kinematics than the commonly used hinge; but also, it allows for a computationally fast model with subject-specific geometries which may increase accessibility for clinical applications compared to a more advanced multi-body contact model.

The second part of the webcast introduces a scalable moving-axis tibiofemoral joint that will be released as a standalone model for attendees to download. Furthermore, an example of how to switch out the generic hinge for a moving-axis knee joint is presented. An overview on how to implement your own knee joint will also be given.
