Table 4. Reliability analysis.

Measurement	Intraobserver reliability	Interobserver reliability
Right LPCO	0.97	0.94
Left LPCO	0.98	0.90
Right LPTS	0.98	0.94
Left LPTS	0.95	0.89
LPCO: Lateral posterior condylar offset; LPTS: Lateral posterior tibial slope; All reliability data were assessed with intraclass correlation coefficient.
