Table 4.

Knee functional outcome measurement among the groups after undergoing TKA procedure evaluated from the first day until the third day.

	ROM D-1	ROM D-2	ROM D-3
	N=10	N=10	N=10
Group 1 (1 hr preemptive analgesia)	15 (10-30)	60 (15-60)	90 (60-90)
Group 2 (72 hrs preemptive analgesia)	15 (15-20)	30 (30-60)	60 (45-90)
Group 3 (Placebo)	15(15-20)	30 (30-60)	60 (60-90)
p-value	0.886	0.131	0.011

The data were not normally distributed.

The p value was measured using Kruskal-wallis nonparametric test.
