Intraobserver and Interobserver Reliabilities of Radiographic Evaluations

Variable	FTA (°)	MAD (°)	mPTA (°)	pTSA (°)	JSW (mm)
Intraobserver reliability	0.975 (0.922–0.990)	0.982 (0.966–0.995)	0.895 (0.718–0.958)	0.825 (0.697–0.872)	0.873 (0.667–0.951)
Interobserver reliability	0.940 (0.780–0.984)	0.939 (0.834–0.975)	0.808 (0.494–0.925)	0.836 (0.690–0.883)	0.853 (0.460–0.955)

Values are intraclass correlation coefficients (95% confidence intervals).

FTA: femoral-tibial angle, MAD: mechanical axis deviation, mPTA: medial proximal tibial angle, pTSA: posterior tibial slope angle, JSW: joint space width.
