3D Reconstruction of the Knee Based on MRI

Sponsor: GCS Ramsay Santé pour l'Enseignement et la Recherche

Summary

ACL tear is a pathology of the knee quite common in athletes mainly caused by a twisting movement. The diagnosis of ACL tear can be confirmed by MRI (magnetic resonance imaging). This method makes it possible to visualize the inside of the knee and to diagnose lesions associated with rupture of the ACL (in particular meniscal lesions). Obtaining a 3D model of patients' joints from a imaging is of growing interest to plan the gesture in preoperative but also to evaluate this gesture postoperatively. In orthopedic surgery, the baseline preoperative imaging is MRI. However, 3D models are generally obtained from a scanner-like imaging. In this context, obtaining a 3D model from MRI imaging would make it possible to have a model that fits into the care pathway patients, without subjecting them to irradiation and visualizing anatomical structures not visible on CT. However, the geometric precision and the reproducibility of the 3D reconstructions of joints reconstructed from an MRI remains unknown and must be evaluated to consider their clinical use.
