title: The long-term effects of tibial drill hole position on the outcome of anterior cruciate ligament reconstruction.
abstract: Fifty-three cases of anterior cruciate ligament reconstruction were classified into two groups depending on the tibial drill hole position: in the anterior group, the center of tibial drill hole was positioned anteriorly to the dome of the intercondylar notch (Blumensaat's line), and in the posterior group, it was positioned posteriorly to the Blumensaat's line. Knee extension loss in the anterior group was significantly greater at 1 and 2 years postoperatively than that of the posterior group. However, there were no differences between the anterior and posterior groups 3 to 5 years postoperatively. No significant differences in anterior laxity were seen from 1 to 4 years postoperatively. After more than 5 years, anteroposterior translation of the anterior group was significantly greater than that of the posterior group. In the anterior group, extension was restricted in the early postoperative period. At latest follow-up more than 5 years postoperatively, anterior laxity in the posterior group was significantly less than that in the anterior group.
