Abstract

PURPOSE: Unlike established knee phenotype classifications, the recently introduced Citak classifications describe the intrafemoral and intratibial knee morphology. The aim of this study was to evaluate the distribution of Citak types A, B and C of the distal femur and proximal tibia in a large cohort and to examine the influence of age, body mass index (BMI) and knee phenotypes.
