Table 2.

For the experienced and less-experienced surgeons, the mean and standard deviation in millimeters (mm) of the target minus the initial femoral resection and those resections with a significant difference between surgeons’ level of experience as determined by the Student’s T test are shown

	Surgeon’s level of experience		Significance
	Experienced (> 50 Calipered KA TKA)	Less experienced (< 50 Calipered KA TKA)
Distal medial target minus initial femoral resection in mm
Mean	− 0.0	− 0.3	p < 0.0001*
Std Dev	0.4	0.5
Distal lateral target minus initial femoral resection in mm
Mean	− 0.0	− 0.4	p < 0.0001*
Std Dev	0.5	0.6
Posterior medial target minus initial femoral resection in mm
Mean	− 0.1	− 0.2	p = 0.0281*
Std Dev	0.5	0.5
Posterior lateral target minus initial femoral resection in mm
Mean	− 0.1	− 0.4	p = 0.0002*
Std Dev	0.5	0.6
