Abstract

Abstract:

Objective　To explore the effective femur tunnel positioning method and primary clinical results in arthroscopic single-bundle anterior cruciate ligament (ACL) reconstruction after the acute anterior cruciate ligament (ACL) rupture.　Methods　All patients with ACL rupture were evaluated after arthroscopic single-bundle ACL reconstruction by means of the autogenous semitendinosus and gracilis tendons and footprint center positioning method in the femur tunnel. The accuracy of the above-mentioned techniques was intra-operatively evaluated through observing the bone marks of lateral femoral epicondyle， and the drawer test，Lachman test, Pivot-shift test, the Lysholm, Tegner and international knee documentation committee (IKDC) scores were used to estimate knee joint function and stability before and after ACL reconstruction.　Results　(1)the lateral femoral epicondyle was found in all the patients during ACL reconstruction, but the resident ridge was found in only 48 patients. (2)after 3 and 24 months of ACL reconstruction, the negative rate was 79%, 77% for the drawer test, 80%, 71% for the Lachman test and 97%, 95% for the pivot shift test.(3) there were significant differences in Lysholm,Tegner,IKDC scores compared with that prior to ACL reconstruction (P<0.01).　Conclusion　The femur footprint center positioning method in the ACL single-bundle reconstruction provides enough knee joint stability and satisfactory clinical results, but the remnant preservation of ligament in the femur footprint is essential and importantly depended on. While the lateral femoral epicondyle can be easily found, that is not the case for the resident ridge.
