A View of Predisposing Factors by Novel 3D Imaging Techniques for the PF Joint

Elimination of predisposing factors by normalizing indicators is considered to be theoretically the best approach for treatment of patellar instability (PI); however, there is a simple question whether current evaluation of predisposing factors is appropriate at all. In other words, the indicators for predisposing factors defined on a plane obtained using conventional diagnostic imaging modalities are sufficiently appropriate in these days when the technologies allow us to reconstruct images to create three-dimensional (3D) models from data obtained by those modalities leading to easier recognition of the real bones and joints. 3D computer models could provide consistent references for direct evaluation which are not affected by location of cross section or knee flexion angle.
