Objective: To retrospectively evaluate the early results of anatomic double-bundle anterior cruciate ligament (ACL) reconstruction and compare with the results of native ACL of the contralateral knee.Methods: The results of a consecutive series of 118 patients receiving arthroscopic ACL reconstruction were evaluated.Eight patients were lost to the latest follow-up,leaving a total of 110 patients available for study within at least 3 years' clinical follow-up.Among them,63 patients underwent postoperative MRI and CT scan,as well as clinical evaluation.Results: After reconstruction,the knees were stable and pain-free.Mean postoperative Lysholm score was 95.54 in 110 patients after 3 years.CT and MRI assessment showed that the reconstruction centered in the femoral footprint of ACL (n=63).The sagittal ACL angle in the reconstructed ACL (52.16°±2.45°) was much close to that in the contralateral intact ACL (51.31 °±2.18°,P＞0.05).By ACL-Blumensaat line angle analysis,there was no difference between doublebundle reconstructed knees and their contralateral normal knees (4.67°±0.43° vs.4.62°±0.60°,P＞0.05).Conclusion:Anatomic double-bundle ACL reconstruction can place grafts more precisely in the anatomic footprint of the ACL and better restore knee kinematics.
