Multivariate analysis of factors associated with the postoperative KSS 2011 (performed with continuous variables).
Parameters | β value (95% CI) | p Value |
---|---|---|
Rotational mismatch in standing (°) | −3.06 (−4.51 to −0.95) | 0.0032 |
Tibial component alignment in coronal plane (°) | 1.82 (−0.35 to 7.83) | 0.0726 |
BMI (kg/m2) | 1.61 (−0.29 to 2.68) | 0.1117 |
Note: Multivariate logistic regression analysis was performed using a stepwise variable entry method. Radiological parameters (preoperative HKA angle, alignments of femoral and tibial components in the coronal, sagittal and axial planes, and rotational mismatch between components) and demographic parameters (sex, BMI) were used in the multivariate logistic regression model.
β is the standard regression coefficient. The bold values indicates statistically significant at p < 0.05.
Abbreviations: BMI, body mass index; CI, confidence interval; KSS, Knee Society Score.
