Table 5 Sensitivity of three commonly used ranges for anatomic limb alignment in predicting knees with valgus malalignment using the mechanical limb alignment method*

From: How accurate is anatomic limb alignment in predicting mechanical limb alignment after total knee arthroplasty?

Parameter Sensitivity (%) 95 % CI p-value
    5-10° 2-10°
3-9° 71 35.8-91.8 <0.001 <0.001
5-10° 43 15.8-75.0 NA NA
2-10° 43 15.8-75.0 NA NA
  1. *Mechanical limb alignments of 7 of 314 (2 %) knees showed valgus malalignment
  2. Abbreviations: CI confidence interval; NA not applicable
