Comparison of motor ability between the two groups after surgery

	PENG group, n = 29	FICB group, n = 28	P value
Quadriceps muscle strength (kg)
Healthy side	8.9 ± 1.1	9.1 ± 0.9	0.422
Affected side 24 h postoperatively	8.6 ± 0.9b	8.2 ± 0.7 a	< 0.001
Affected side 48 h postoperatively	8.7 ± 0.8b	8.5 ± 0.5 a	< 0.001
Time of initial ambulation after surgery (hours)	11.3 ± 2.3b	18.7 ± 1.5	< 0.001

Data are presented as mean ± SD. ^a Denotes statistical significance compared to the quadriceps muscle strength of the healthy side within the group. ^b Denotes statistical significance between the groups.
