Association between meniscal tears and the peak external knee adduction moment and foot rotation during level walking in postmenopausal women without knee osteoarthritis: a cross-sectional study

Table 3 Association between foot rotation during early and late stance and the presence and severity of meniscal tears

	Univariate regression coefficient (95% CI)	P value	Multivariate regression coefficient (95% CI)^a	P Value
Early stance
Any medial meniscal tear y/n^b	1.7 (-5.1, 8.5)	0.6	0.16 (-5.6, 8.9)	0.6
Medial meniscal tear score^c	1.1 (-2.7, 4.9)	0.5	1.1 (-3.0, 5.1)	0.6
Any lateral meniscal tear y/n^b	1.9 (-5.8, 9.6)	0.6	1.9 (-6.2, 9.9)	0.6
Lateral meniscal tear score^c	1.1 (-4.6, 6.9)	0.7	1.1 (-4.8, 7.1)	0.7
		0.6
Late stance
Any medial meniscal tear y/n^b	6.3 (1.1, 11.6)	0.02	6.2 (0.5, 11.8)	0.03
Medial meniscal tear score^c	3.6 (0.6, 6.6)	0.02	3.5 (0.35, 6.6)	0.03
Any lateral meniscal tear y/n^b	2.3 (-4.6, 9.3)	0.5	2.2 (-4.9, 9.3)	0.52
Lateral meniscal tear score^c	1.0 (-4.2, 6.3)	0.7	1.1 (-4.2, 6.5)	0.6

^aAdjusted for age. ^bIncrease in early stance peak adduction moment if a meniscal tear is present (tear = 1, no tear = 0). ^cIncrease in peak adduction moment for each increase in grade of meniscal tear score. Positive foot rotation values indicate internal rotation and negative values represent external rotation. CI, confidence interval.
