Table 2.

Hip-knee-ankle (HKA) angle, varus/valgus position of the tibial and femoral components (tibia AP and femur AP), and flexion/extension of the tibial and femoral components (tibia sagittal and femur sagittal). Positive values indicate varus, posterior tibial slope, and femoral component flexion. Negative values indicate valgus, anterior tibial slope, and femoral component extension. Outliers are defined as being more than 3° from the desired position and numbers of outliers are shown depending on the extent of being more than 3° from the ideal position
