Table 2.

Matz et al. (35) showed that increased, maintained, or decreased AFO, APFD, and APD were not significantly associated with changes in postoperative WOMAC or KSS scores. P-values are presented in the table.

	AFO*	APD†	APFD‡
ROM	0.690	0.060	0.883
KSS	0.885	0.619	0.620
KSFS	0.519	NR	0.440
KSPS	0.735	NR	0.300
WOMAC	0.681	0.490	0.589
Pain SS	0.904	0.236	0.259
Function SS	0.647	0.703	0.316
Stiffness	0.098	NR	0.316

*Stuffing defined as AFO increased by at least 1mm (2.8 average); ^†Stuffing defined as APD increased by at least 1mm (3.1 average); ^‡Stuffing defined as APFD increased by at least 1mm (4.7 average).

SS, subscale.
