Adding ligaments without knowing resting length

Post by Kenneth Smale » Tue Oct 24, 2017 10:55 am

Hi Everyone,

I’m applying patient-specific knee joints to the Rajagopal model based on MRI data. Therefore, I am able to discern the ligament origins and insertions as well as CSA but I am unsure how to go about determining their resting lengths. I.e. I do not know at what length these ligaments go from slack to taut and start providing force to the system. Has anyone implemented ligaments from MRI before? How did you overcome this unknown resting length issue?
