Table 2.

Sensitivity factor between each DOF in the simulated PAO and the abduction and flexion moment arms of the rectus femoris and primary hip abductors of ALD (anterolateral deficient) and PLD (posterolateral deficient). ⁺ indicates strong sensitivity (r ≥ 0.6) and * indicates moderate sensitivity (0.4 ≤ r < 0.6).
