Basal and follow up values of the WOMAC index of the studied groups. Data are expressed as median (range)

	Group (I) n=28	Group (II) n=28	P
Basal (before block)	65 (62.3-71)	70.5 (65.5-72)	0.1
2 weeks	58 (56.3-46.8)†	54.5 (53.3-39.8)†	0.001*
4 weeks	55.5 (53.3-61.5)†	52 (50-54.8)†	0.001*
8 weeks	55.5 (53.3-61.5)†	50 (48-53.5)†	<0.0001*
12 weeks	59.5 (54.3-63.8)†	56.5( 51.3-56.8)†	0.001*

Group (I): Received ultrasound-guided ACB (adductor canal block). Group (II): Received ultrasound-guided ACB and I-PACK. WOMAC: Western Ontario and MC Master Universities. *P≤0.05 was considered as statistically significant between the two groups. ^†P≤0.05 was considered as statistically significant in comparison with basal value
