Model Configurations:

All:

• Material properties all default
• Full Newton's method
• Reaction forces/moments recorded for tibia and femur

Only Cartilage to cartilage (C2C) contact defined (c2c.feb):

• 5 mm z displacement (knee compression) with all other DoF fixed (ran to crash)

C2C and cartilage to meniscus (C2M) contact defined (c2c_c2m.feb):

• 2 mm z displacement (knee compression) with all other DoF fixed (ran to crash)

C2C and C2M with ligaments rigidly attached to bones (LB) (c2c_c2c_lb.feb):

• 2 mm z displacement (knee compression) with all other DoF fixed (ran to crash)
