Comparison of Clinical and Radiological Results between Posteromedial Portal Technique and Posterior Transseptal Portal Technique in Making a Tibial Tunnel in Single Bundle Posterior Cruciate Ligament Reconstruction with Remnant Preservation / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study is to compare the clinical and radiological results between posteromedial portal technique and posterior transseptal portal technique in making a tibial tunnel in single bundle posterior cruciate ligament (PCL) reconstruction with remnant preservation. MATERIALS AND METHODS: Thirty-three cases of posteromedial portal technique and 35 cases of posterior transseptal portal technique in making a tibial tunnel in single bundle PCL reconstruction with remnant preservation were evaluated retrospectively. The clinical evaluation, including function and stability, was assessed. The tibial tunnel placement was measured using computed tomography. RESULTS: At final follow-up, the clinical results showed significant improvement compared to preoperation in both groups. There were no significant differences in clinical results including function and stability in both groups. The centers of tibial tunnels by posteromedial portal technique were placed more medially and proximally than those of the posterior transseptal portal technique. CONCLUSION: Remnant preserved single bundle PCL reconstructions by posteromedial portal technique and posterior transseptal portal technique were good methods for restoring function and stability compared to preoperation. There were no significant differences in clinical results in both groups. However, the tibial tunnels by posteromedial portal technique tended to be more medial and proximal placements than those of the posterior transseptal portal technique.
