Distal femur morphology and the suitability of standard guides for knee arthroplasty in the Turkish population

Abstract

Objective: The aim of this study was to evaluate the posterior condylar angle (PCA) and condylar twist angle (CTA) of the distal femur in the Turkish population and its concordance with the current standard prosthesis guides used in total knee arthroplasty (TKA). Methods: Two hundred and forty knees of 120 Turkish subjects (60 male and 60 female) were included in this study. PCA, CTA, femoral mediolateral lengths (fML), medial femoral anteroposterior lengths (fMAP), lateral femoral anteroposterior lengths (fLAP), distances between the trochlear groove and fMAP (DBTG–fMAP), distances between the trochlear groove and fLAP (DBTG–fLAP), medial posterior condylar cartilage thickness (MPCCT) and lateral posterior condylar cartilage thicknesses (LPCCT) were measured on magnetic resonance imaging (MRI). Results: The median CTA was 7° (range: 0°-13.0°) and the median PCA was 4° (range 0°-11.0°) (P
