Abstract
In anatomic double-bundle ACL reconstruction, it is technically demanding even for experienced surgeons to place two femoral tunnels within ACL attachment. We describe a technique using three-dimensional (3D) fluoroscopy-based navigation system to place two femoral tunnels accurately during anatomic double-bundle ACL reconstruction. After a reference frame is rigidly attached to a femur, intra-operative 3D image of the distal femur was obtained with C-arm of Arcadis Orbic (Siemens, Germany). The image was transferred to a navigation system (StealthStation navigation system, Medtronic, Louisville, CO) and reconstructed into a 3D image of the distal femur.
