Abstract
We report the clinical results of anatomically oriented anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone graft (BTB). This technique is intended to mimic the two bundles of the normal ACL, based on the concept of twin tunnel ACL reconstruction. The attached bone plug is introduced into a rectangular femoral socket via a halfway rectangular tibial tunnel in order for the anterior portion of the graft to function as the anteromedial bundle (AMB) and its posterior portion to behave as the posterolateral bundle (PLB). Between July 2007 and December 2009, 47 patients (26 men and 21 women) underwent ACL reconstruction. The mean patient age was 29.0 years (range, 14 to 54 years) and the average follow-up period was 13.8 months (range, 6 to 27 months). Pivot shift test gave a slightly positive result in 5 patients, and the anterior drawer test gave a slightly positive result in 4 patients. The mean KT-2000 side-to-side difference was 0.65 mm (range, -4.0 to +5.0 mm). The mean Lysholm score was 95.4 (range, 85 to 100). Slight rotation instability remained after ACL reconstruction, but fresh meniscal injury was negligible in all cases. The clinical results of anatomically oriented ACL reconstruction with a BTB were good.
