Table 3.

For the experienced and less-experienced surgeons, the proportions of initial and corrected femoral resections within different ranges from the KA target, and the results of a Fisher’s Exact Test that computed the significance of differences between the 203 patients treated by 10 experienced and 58 patients treated by four less-experienced surgeons are shown

	Surgeon’s level of experience
