title: [Clinical and radiographic correlation after anterior cruciate ligament reconstruction].
abstract: The purpose of this work is to correlate the clinical, functional and radiographic results of the anterior cruciate ligament (ACL) reconstruction with the angulation and orientation of the femoral and tibial tunnels.
  
  
  BACKGROUND
  The ACL is one of the most frequently injured articular structures of the knee. The reason for this being that it is the primary limiting structure of anterior tibial translation; its tear causes kinematic alterations and results in long-term degenerative and functional changes. Repair can restore the kinematics.
  
  
  METHODS
  26 patients, 20-50 years old, post-ACL reconstruction with the semitendinous-gracilis technique. From November 2006 to July 2007. Clinical and functional assessments: Tegner and Lysholm. Radiographic assessment: anteroposterior view with knee extension and lateral view with 30 degrees flexion. Pearson correlations (r) were used in the analysis.
  
  
  RESULTS
  26 patients (100%), 20 males (76.92%), 6 females (23.08%). Mean of 2.4 in the Lysholm scale (fair to good); standard deviation 1.2. Bernard-Lysholm quadrant r = -0.772. Tegner quadrant r = 0.790.
  
  
  CONCLUSIONS
  The Lysholm and Tegner scale is associated with the graft quadrant. The situation of the tibial implant in the saggital plane is associated with the Lysholm scale. The correlation of patients with an inadequate placement with respect to the quadrants was associated with good-to-excellent results and fair-to-good results. Two patients had a poor clinical outcome; the orientation of the AP angle and the quadrant were within acceptable parameters, with the exception of the lateral angle-shaft axis.
