Intermethod ICC Values of Each Simplified Formula Versus Ideal Correction Angle Method a
DV: Explicative Variable | Intermethod ICC (95% CI) b |
---|---|
Regression value | |
Miniaci | 0.881 (0.822-0.921) |
TCA – ΔJLCAvalgus | 0.819 (0.733-0.879) |
TCA – ½ΔJLCAvalgus | 0.976 (0.964-0.985) |
TCA – ⅓ΔJLCAvalgus | 0.992 (0.988-0.995) |
a DV, dependent variable; ICC, intraclass correlation coefficient; JLCA, joint-line convergence angle; ΔJLCAvalgus difference in JLCA between standing-leg and valgus stress radiographs; TCA, target correction angle.
b Each ICC value, P < .0001.
