Three-dimensional joint surface orientation does not correlate with two-dimensional coronal joint line orientation in knee osteoarthritis: Three-dimensional analysis of upright computed tomography

Knee osteoarthritis (OA) is the most common form of arthritis, affecting around 30% of adults over 60  years old [1]. The causes of knee OA have traditionally been divided into biological and mechanical factors, with lower limb malalignment representing one of the mechanical factors [2]. Alignment parameters based on two-dimensional (2D) coronal radiography, such as the Mikulicz line and femorotibi al angle (FTA), have been widely used for the diagnosis of, selection of treatment strategies for, and pre- and postoperative evaluations of OA [3,4].
