The influence of computer-assisted surgery experience on the accuracy and precision of the postoperative mechanical axis during computer-assisted lateral closing-wedge high tibial osteotomy

Table 5 Comparison of the intraclass correlation coefficient between radiographic and navigation measurements in early and late cohorts of computer-assisted lateral closing-wedge high tibial osteotomy

		Early cohort	Late cohort	Total
Preoperative mechanical axis (°)^a	r	0.558	0.663	0.618
Preoperative mechanical axis (°)^a	P	<0.001	<0.001	<0.001
Postoperative mechanical axis (°)^a	r	0.310	0.376	0.329
Postoperative mechanical axis (°)^a	P	0.011	0.001	<0.001

^aMechanical axis, angle between the femoral and tibial mechanical axes; negative values indicate varus angles
