Comparison of surgery-related information and results between the three-dimensional printed combined navigation template group (group A) and traditional surgery group (group B)

	Operation time	X-ray exposure	Growth plate cartilage or articular cartilage injury	Achieve the treatment goals at the last follow-up
	(min)	(time)*	Yes	Yes	No
Group A	20.78±2.36	3.50±0.65	0	18	3
Group B	28.39±2.35	4.70±0.88	3	20	4
P value	0.00	0.00	0.094	0.826

Data were presented with mean±SD.

P values were obtain by analysis of variance for quantitative data and by χ² test for qualitative data.

* Times means the exposure numbers of X-ray.

SD, standard deviation.
