Interobserver reliability: intra-class correlation coefficients (ICC) for the operative and nonoperative limbs

	ICC	CI	p-value
Operative limb
Tibial slope	0.75	0.41 to 0.91	0.001
mLDFA	0.82	0.67 to 0.90	< 0.001
mMPTA	0.88	0.77 to 0.94	< 0.001
MAD	0.93	0.86 to 0.98	< 0.001
Nonoperative limb
mLDFA	0.86	0.68 to 0.95	< 0.001
mMPTA	0.98	0.94 to 0.99	< 0.001
MAD	0.92	0.81 to 0.97	< 0.001

CI, confidence interval; mLDFA, mechanical lateral distal femoral angle; mMPTA, mechanical medial proximal tibial angle; MAD, mechanical axis deviation
