Abstract: The invention relates to a computer-implemented method and an associated device for modelling a joint of a patient for real-time assistance in performing at least one bone tunnel by arthroscopy in said joint, said method comprising: receiving a stream of intraoperative monocular two-dimensional images obtained using an imaging device, each of the intraoperative monocular two-dimensional images being obtained at a time t and comprising at least a region of interest of the joint; for each intraoperative monocular two-dimensional image, calculating a depth map associated with time t by implementing a first previously trained learning model, said first learning model being configured to receive as input at least said intraoperative monocular two-dimensional image obtained at time t; calculating a current partial three-dimensional model of the patient's joint associated with a current time tc, on the basis of at least one depth map associated with the current time tc, at least one depth map associated with a previ

Abstract: A system for assisting in real time in the production of at least one bone tunnel by arthroscopy in a joint of a patient, including an imaging device able to acquire two-dimensional images of portions of the joint of the patient, a first monitoring device and a programmable device.
