GARCIA-DOBARGANES-BARLOW, FE et al. Radiographic evaluation of femoral and tibial tunnel position in anterior cruciate ligament reconstruction with anatomic technique. Acta ortop. mex [online]. 2021, vol.35, n.4, pp.327-330.  Epub 23-Mayo-2022. ISSN 2306-4102.


Reconstruction of the anterior cruciate ligament attempts to reproduce the native ligament; make independent tunnels optimize the entry points and effectiveness the anatomy. Perform radiographic measurements of the knee, identify position of femoral and tibial tunnels in patients operated for reconstruction of anterior cruciate ligament with anatomical technique.

Material and methods:

Patients were identified in the period January 2018 to December 2019. 98 patients were retrospectively evaluated. Radiographic measurements in the femur, the inclination angle of the tunnel, the insertion site with respect to the Blumensaat line and the transosseous distance were determined. In tibia, the location in percentage of the tibial plateau location in anteroposterior and lateral view, tibial tunnel angle.


Postoperative patients were 98. (75.5%) male, female (24.5%). Postoperative in 2018 (57.15%) and 2019 (42.85%) Age range: affected group was 21-25 years, right side affected in 57.15%; Radiographic measurements in femur, the angle of inclination of the tunnel was 45o, percentage in the Blumensaat line was 20%, and the transosseous distance was 3.43 cm. In tibia the percentage distance in anteroposterior projection was 44%, and lateral 28%, The angle in tibial tunnel anteroposterior projection of 73 degrees, and lateral 114.


The anatomical technique is a good option to perform tunnels with an optimal anatomical position. By making independent tunnels it allows to improve coverage of normal antomic footprint. Increases degrees and inclination of tunnels, causes added injuries.
