Conventionally, a simple radiograph of three joints is usually requested as a preliminary step, and if the surgeon suspects any additional deformities, they may or may not ask for additional imaging to measure factors such as anteversion, TT-TG, or tibial torsion. However, with the 3D assessment approach, all measurements are obtained in a comprehensive manner, allowing for a complete evaluation of the patient’s anatomy. This approach ensures that all indices outside the normal range are brought to the surgeon’s attention, thereby minimizing the likelihood of missing any abnormality. The 3D assessment report provides a more holistic and accurate picture of the lower limb, making it an essential tool for surgeons dealing with complex anatomies or severe distortions. By allowing for a complete evaluation of the limb’s 3D geometry and providing measurements for all relevant indices, our approach ensures a more precise and effective surgical plan.

In cases where there is severe distortion of the anatomy, traditional 2D imaging may not be sufficient to accurately assess and study the affected area. By using 3D assessment, each bone can be evaluated as a whole and in its proper orientation, allowing for more precise measurements and a better understanding of the overall anatomy. In addition, many landmark and index definitions that may be used in 2D imaging may no longer be applicable in severely distorted anatomies. 3D assessment allows for a more comprehensive evaluation that takes into account all aspects of the anatomy, including any abnormalities or distortions that may be present.
