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 P value | Correlation coefficient | Slope P 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.
