Video-based computer navigation in knee arthroscopy for patient-specific ACL reconstruction.

abstract：PURPOSE:Knee arthroscopy suffers from a lack of depth information and easy occlusion of the visual field. To solve these limitations, we propose an arthroscopic navigation system based on self-positioning technology, with the guidance of virtual-vision views. This system can work without any external tracking devices o...
