» The coronal plane alignment of the knee (CPAK) classification is a practical
and straightforward framework to define a patient's constitutional coronal knee
limb alignment and joint line obliquity. » Patients are assigned to one of nine
phenotypes using two straightforward calculations; the arithmetic hip-knee-ankle
angle (aHKA) and the arithmetic joint line obliquity (aJLO). » CPAK allows clear
understanding of the geographical and gender variations in knee alignment, as
well as the differing outcomes of knee reconstructive surgery, based on
phenotype. » CPAK enables surgeons to tailor their alignment strategy to best fit
a patient's constitutional phenotype and avoid the drawbacks of a "one-size fits
all" approach.
