Abstract
ObjectiveTo 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. MethodsThe 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. ResultsAfter 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 double-bundle reconstructed knees and their contralateral normal knees (4.67°±0.43° vs. 4.62°±0.60°, P>0.05). ConclusionAnatomic double-bundle ACL reconstruction can place grafts more precisely in the anatomic footprint of the ACL and better restore knee kinematics.
