Abstract

Objective: This study had the objective of prospectively comparing transverse fixation (Cross-Pin™) with extracortical fixation (EZLoc™) for the femur, in surgical reconstruction of the anterior cruciate ligament, from a clinical, biomechanical and functional point of view.

Methods: Between April 2007 and November 2009, 50 patients with acute or chronic anterior cruciate ligament injuries underwent arthroscopic reconstruction using the homologous flexor tendons (gracilis and semitendinosus). Randomization of the femoral fixation method was done by means of a draw at the time of the procedure. Patients were excluded if they presented multiple ligament lesions, fractures, previous surgery, autoimmune disease and impairment of the contralateral knee. The Lysholm scale, SF36 quality-of-life questionnaire and KT1000™ arthrometer were used.

Results: After a mean follow-up of 18.1 months, there were no statistically significant differences between the groups regarding the Lysholm scale and KT1000™ measurements. However, the SF36 questionnaire showed a statistical difference such that transverse fixation was superior regarding pain and vitality.

Conclusion: Both techniques were shown to be efficient for transfemoral fixation, but with almost no statistically significant difference between them. We believe that new studies will be necessary for better understanding of these differences.
