Figure 3

Calculated tibiofemoral joint compressive force and V-V contact moment (mean ± std) during level walking, walking down stairs, and chair rise/sit. The V-V moment is represented as positive (negative) when the femur generates a contact force on the lateral (medial) plateau of the insert. Values estimated in this study are compared to instrumented implant data of two representative patients from the literature. Events for gait and stair descent: Heel-strike at 0% and 100% of cycle, toe-off at 60–65% of cycle, contralateral heel-strike at 50–55% of cycle.
