Table 2 Perioperative data

Parameters	CAS-TKA	Bone-Resect-TKA	P value
Parameters	n = 22	n = 28	P value
Perioperative data

Difference of perioperative hemoglobin level (g/dL)	1.1 (0.4–2.1)	1.8 (0.6–2.5)	0.112

Data are mean (range) or (%). P for between-group comparisons was determined using χ ² tests for categorical variables and t tests for continuous variables
