Table 4.

Mean (SD) change scores and standardized response means (SRM) for SF-BIA, SPP CM, and 10cmSPP CM of swelling over interval 1 and 2. Change was calculated as 2 week minus pre-TKA (interval 1) and 6 week minus 2 week (interval 2).

Measure	Preop to 2 Week			2 week to 6 Week
	N	Mean Change (SD)	SRM	N	Mean Change (SD)	SRM
SF-BIA (Ratio)	50	−0.26 (0.09)	−2.86	46	0.06 (0.07)	0.92
Circumference SPP (Ratio)	50	0.10 (0.07)	1.50	45	−0.055 (0.06)	−0.97
Circumference 10cm SPP (Ratio)	50	0.02 (0.13)	0.16	45	−0.02 (0.04)	−0.54

Negative values indicate increase in swelling when measured using SF-BIA, while negative values for CM indicate decreases in swelling.
