Measuring the anterior cruciate ligament’s footprints by three-dimensional magnetic resonance imaging

Abstract

Measuring the ACL's footprint by 3D MR imaging or open cadaveric dissection has strong agreement and can be used interchangeably. 3D MR imaging has the potential to allow surgeons to: (1) tailor ACL reconstruction technique or graft choice based on ACL footprint size, (2) plan for selective bundle ACL reconstruction for partial tears, and (3) preoperatively template tunnel position according to the patient's individual anatomy.

MRI evaluation of the four tunnels of double-bundle ACL reconstruction

“…One was the lack of three-dimensional (3D) MRI sequences in the evaluation of tunnel locations. Previously, 3D MRI has been used in studies of native ACL attachments (28) and SB ACL reconstruction tunnel locations (9). In our study, the measurement of the femoral tunnel locations using sagittal images with 4 mm slice thickness proved especially challenging (Figs.…”

Diagnostic accuracy of magnetic resonance imaging in detecting anterior cruciate ligament injuries

“…15 3D MR imaging has the potential to allow surgeons to: (1) tailor an ACL reconstruction technique or graft choice based on the ACL footprint size, (2) plan for selective bundle ACL reconstruction for partial tears, and (3) preoperatively template tunnel position according to the patient's individual anatomy. 16 MRI has high accuracy for patients with complete ACL rupture. Due to the higher economic costs and increased complication risks of diagnostic arthroscopy, MRI is therefore recommended as the principal investigation following clinical examination, to diagnose ACL rupture.…”

Combined Intra- and Extra-articular Reconstruction of the Anterior Cruciate Ligament: The Reconstruction of the Knee Anterolateral Ligament

“…The tibial tunnel is made within the topography of the native ACL tibial footprint. 15,16 We first insert a guidewire and then perform the drilling of the tunnels. The surgeon can make both the femoral and tibial tunnels using a standard ACL tibial guide, just adjusting the guide angulation to reach the correct footprints; no special equipment is required to perform this technique.…”
