“…13,14 Although some improvements have been made, above techniques do not substantially eliminate the killer turn. 15 In order to avoid the acute angle between the graft and bone tunnel, Fanelli et al [16][17][18] introduced an alternative technique by creating a tibial tunnel below to the PCL tibial anatomic insertion. This distal tibial tunnel minimized PCL graft bending and was found to decrease stress concentration between the graft and tunnel exit which appeared to provide a superior solution to overcome the killer turn effect.…”

No consensus has been reached on the optimal position of PCL tibial tunnel. The purpose of this study was to compare the biomechanical properties of proximal, distal and anatomic tibial tunnel in transtibial posterior cruciate ligament reconstruction. An in-vitro model of transtibial posterior cruciate ligament reconstruction was simulated using porcine tibias and bovine extensor tendons. Two models of biomechanical testing, load-to-failure loading, and cyclic loading, were performed in this study. The load-to-failure loading found that distal tibial tunnel resulted in greater ultimate load and yield load than the anatomic and proximal tunnel group ( p < 0.05), whereas there were no significant differences in mean tensile stiffness among three groups ( p > 0.05). The cyclic loading found no differences in the graft displacement at 250, 500, and 1000 cycles among three groups ( p > 0.05). It was found that distal tibial tunnel showed superior ultimate load and yield load in load-to-failure loading testing compared with proximal and anatomic tibial tunnels, whereas no significant difference was found in terms of the mean displacement of the survived grafts in cyclic loading testing among three groups.

Editorial Commentary: Posterior Cruciate Ligament Remnant Preservation Has Hypothetical Advantages

Abstract: Posterior cruciate ligament (PCL) remnant preservation has hypothetical advantages, but studies directly comparing PCL reconstruction with or without remnant preservation are not identified.
