Comparison of anatomic ACL reconstruction between selective bundle reconstruction and double-bundle reconstruction.
OBJECTIVE
The objective of this study was to compare the clinical and radiologic results of preserved ligament remnants in the selective bundle anterior cruciate ligament (ACL) reconstruction and totally sacrificed ligament remnant in the double-bundle ACL reconstruction in order to confirm the evidence of selective bundle reconstruction.


METHODS
This retrospective comparative study was conducted for comparison between preserved ligament remnants in the selective bundle ACL reconstruction and totally sacrificed ligament remnant in the double-bundle ACL reconstruction. From 2008 to 2010, 16 patients (group I) underwent selective bundle ACL reconstruction and 30 patients (group II) underwent double-bundle ACL reconstruction. Clinical, stability and radiologic results (tunnel locations of femoral tunnels using 3-D computed tomography and graft signal intensity using magnetic resonance imaging) were compared.


RESULTS
In comparison with functional results, no statistical differences in the Lysholm, Tegner and International Knee Documentation Committee scores were observed between the two groups (n.s.). In comparison with stability results between the two groups, no statistical differences were observed in the Lachman, pivot shift and anterior drawer stress tests using a Telos device at 30° and 90° flexed positions (n.s.). In evaluation of the femoral tunnel location, no statistical significant differences in the tunnel position were observed between the groups (n.s.). No statistically significant differences in signal intensity were observed between the two groups (n.s.).


CONCLUSIONS
Compared to the double-bundle ACL reconstruction, selective bundle ACL reconstruction produced comparable clinical and radiologic results. Selective bundle ACL reconstruction could be performed instead of double-bundle ACL reconstruction if some intact bundle exists.
