CPAK Calculator
Welcome to CPAK CALCULATOR, a tool designed for orthopedic surgeons seeking to integrate the coronal plane alignment approach proposed by MacDessi. Our calculator allows easy calculation of the CPAK subphenotype and, in addition, through the range calculation function, predicts which combinations of MPTA and LDFA keep the patient within a given subphenotype.
Why CPAK Calculator?
Integral and Simple Classification
The CPAK classification provides an easy-to-use and user-friendly system for describing the alignment of the arthritic knee, facilitating communication and encouraging future research.
Allows guiding a patient-specific alignment
The CPAK classification allows to identify which patients will benefit most from a customized or systematic alignment.
Personalized preliminary assessment
The CPAK classification provides surgeons with a simple preoperative tool to decide the best alignment strategy for each patient based on individual knee phenotypes according to the CPAK philosophy.
