Graft placement after the anterior cruciate ligament reconstruction: a new method to evaluate the femoral and tibial placements of the graft.

In order to evaluate graft placement of the anterior cruciate ligament (ACL) reconstruction and its relationship to the clinical outcome of the patient, 100 patients were examined 7 years after an ACL reconstruction. Clinical assessment was performed using the standard knee ligament evaluation form of the International Knee Documentation Committee (IKDC), and the Lysholm and the Marshall knee scores. We developed a new evaluation method of graft placement after an ACL reconstruction, 'the sum score of the graft placement', which takes into account both the femoral and the tibial positions of the graft simultaneously, and our study showed that 'the sum score of the graft placement' has an association to clinical outcome of patients and that it can better explain the long-term osteoarthritic changes at the injured knee than the separate measurements of the femoral and tibial tunnel placements.
