Frontal-plane relationship between hip centers and ground reaction forces during static standing and gait: Implications for preoperative planning of total knee arthroplasty
A 20 cm-stance width best aligns the GRF with Mikulicz line in static standing. Single-leg and closed-leg standing replicate GRF direction during gait. These findings may inform preoperative planning of total knee arthroplasty but require validation in larger and patient-based cohorts, given the small sample size and restriction to healthy subjects. This exploratory study should be interpreted with caution regarding direct clinical application.
