The Relationship between Knee Adduction Moment and Knee Osteoarthritis Symptoms according to Static Alignment and Pelvic Drop

Table 2

Linear relationships between KAM-related measures (independent variable) and VAS pain/HSS score (dependent variable) according to the more affected side in the varus and valgus groups.

KAM-related measures	VAS pain		HSS score
	Correlation coefficient	Slope value	Correlation coefficient	Slope value
Peak KAM (Nm/(BW × HT)%)
Varus group	0.293	≤0.001	−0.149	0.045
Valgus group	−0.446	0.006	0.340	0.043
KAM impulse (Nm·s/(BW × HT)%)
Varus group	0.380	≤0.001	−0.253	0.002
Valgus group	−0.277	0.102	0.112	0.516

KAM: knee adduction moment; BW: body weight; HT: height; VAS: visual analog scale; HSS: the hospital for special surgery.
