The displacement of the femur and gap displacement in four models. The maximum femoral displacements in ICCS, 7.3-PTOS, 4.5-FTOS and 7.3-FTOS models were 10.40 mm, 8.08 mm, 7.71 mm, and 7.15 mm, respectively. The maximum gap displacement measured 2.73 mm, 1.19 mm, 0.94 mm, and 0.55 mm, respectively
