Abstract

Purpose : The majority of PCL deficient knees have some intact remnant PCL bundles. In these cases, the remnant PCL bundles were removed fur easy passage of graft(especially in bone-patellar tendon-bone graft). The purpose of study is to report the results of PCL reconstruction by posterior transseptal portal technique and by preserving the remnant posterior cruciate ligament bundles. Materials & Methods : From November 1993 to June 1999, 44 arthroscopic posterior cruciate ligament reconstructions have been performed by one surgeon. We studied 37 knees those were followed up over 1 year among them. The mean age($14\~56$ years) was 31.8 years. The average follow-up period was 17.8 months($12\~61$ months). The graft materials were 29 double-loop hamstring autografts, 4 double-loop hamstring allografts and 4 Achilles tendon-bone allograft. Results : There are significant improvement of the preoperative subjective symptoms. The last follow-up shows that the average Lysholm knee score was markedly improved from 59.8 pre-operation to 89.2 post-operation and the average KT 2000 side difference was decreased from 11.1mm pre-operation to 2.3 mm post-operation. Follow-up MRI showed that the graft was healed with remnant posterior cruciate ligament bundles as one ligament. Conclusion : The posterior trans-septal portal makes it possible to locate the exact tibial tunnel. The arthroscopic PCL reconstruction preserving the remnant of original PCL bundles seems to provide the good result.
