Abstract: Provided are a tunnel position determination system and method for anterior/posterior cruciate ligament reconstruction, which relate to the technical field of ligament reconstruction. The system includes: a coordinate system establishment module for establishing a femoral coordinate system and a tibial coordinate system; a feature point selection module for selecting femoral feature points and tibial feature points; and a tunnel position determination module for determining a femoral point and a tibial point during reconstruction on the basis of the femoral feature points and the tibial feature points, and determining a specific tunnel position of an anterior or posterior cruciate ligament reconstruction tunnel by means of the femoral point and the tibial point. The present disclosure provides a method for selecting the femoral point and the tibial point during tunnel reconstruction, such that a specific path of a formed reconstruction tunnel is more accurate.

Abstract: Provided is a positioning system for posteromedial structure, posterolateral structure and medial patellofemoral ligament reconstruction, which relates to the technical field of ligament reconstruction.
