The flexion space is more reliably balanced when using the transepicondylar axis as compared to the posterior condylar line

摘要

Purpose The purpose of this study was to evaluate the differences in flexion space balance when the femoral component is implanted parallel to the surgical transepicondylar axis (TEA) or with 3 degrees of external rotation from the posterior condylar line (PoCoLi). It was hypothesized that implantation parallel to the TEA will produce a more reliably balanced flexion space.
