				P
Characteristics	Control group	sTXA	aTXA	Control vs sTXA	Control vs aTXA	sTXA vs aTXA
Intraoperative blood loss	300.0 ± 100.0	287.5 ± 103.1	218.6 ± 84.96	.967	.0121	.3279	Ordinary 1-way ANOVA (Tukey multiple comparisons)
Postoperative blood loss	791.7 ± 302.2	474.9 ± 207.3	349.9 ± 219.5	<.0001	<.0001	.0653	Ordinary 1-way ANOVA (Tukey multiple comparisons)
No. of transfusion patients (yes/no)	17/24	2/39	7/34	.0001	.0278	.1549	Fisher exact test

ANOVA = analysis of variance, aTXA = topical intra-articular administration tranexamic acid, sTXA = systemic administration tranexamic acid.
