I created a subject-specific knee model using the FDK method, according to the 5th challenge compitation data. I am trying to simualte the leg-suqatting and chair sit and rise gait cycles.
But the results of tibia-femoral and patellar-femroal contact forces are too high, about 3000N and 5000N, respectively.
And I am trying to adjust the ligaments (MCL LCL MPFL LPFL PCL …), but it seems doesn’t work. I think it may related to the patella tendon stiffness, my question is how to adjust the patella tendon stiffness in Anybody 6.0?
