Effects of Knee Osteoarthritis on Hip and Ankle Gait Mechanics

Table 3

Mean peak moment of each joint.

		Knee OA group (n=89)	Control group (n=42)	p-value
		Mean (SD)	Mean (SD)
Sagittal	Knee extension	2.44 (1.16)	3.38 (1.03)	<0.001
	Hip flexion/extension	6.41 (1.19)	6.94 (0.89)	0.010
	Ankle plantar flexion	7.1 (1.15)	7.64 (0.61)	0.005
	Total sagittal moment	15.94 (2.43)	17.97 (1.59)	<0.001
Coronal	Knee adduction	3.27 (0.92)	2.76 (0.65)	0.002
	Hip abduction	4.93 (0.83)	5.34 (0.54)	0.005
	Ankle varus	0.69 (0.44)	0.46 (0.36)	0.005
	Total coronal moment	8.89 (1.58)	8.56 (1.13)	0.239

The unit of moment is %BwHt. SD: standard deviation
