Objective To evaluate the clinical efficacy of arthroscopic double-bundle reconstruction of posterior cruciate ligament with double-femur-tibia-tunnel and remnant preservation.Methods From June 2007 to June 2010,15 patients were treated with single-femur-tibia-tunnel reconstruction and 18 patients were treated with double-femur-tibia-tunnel PCL reconstruction with remnant preservation under arthroscopy.The two femoral tunnels were placed on footprint,anterolateral bundle was centered at 12mm from the upper apex of femur condyle and 7mm from the remote articular cartilage,while posteromedial bundle was centered in the footprint according to the adjacent method.Residual PCL and surrounding synovial tissue was saved during the procedure.Hamstring tendon was used as autograft.The AL bundle was tightened and fixed in 70° degree of flexion,and PM bundle was tightened and fixed in 0° degree.Results All the patients were followed up.Average follow-up was 32.6 (42 ～ 24) months in the single tunnel group and 30.4 (39 ～ 24) months in the double tunnel group.All the patients showed negative PDT.The Lysholm score was (91.4 ± 3.6) and (93.3 ± 2.8) in the single and the double tunnel groups,with no statistical significance between the two groups (P＞0.05).Measured by KT-1000 arthrometer,the posterior tibial translation was (5.8 ± 0.4) and (5.2 ± 0.6)mm in the single tunnel group at 0° and 60° flexion,while it was (3.4 ± 0.3) and (3.9 ± 0.5)mm in the double tunnel group,with a statistical significance (P＜0.05).At 90° flexion,however,no significance was found between the two groups (P＞0.05).Conclusions PCL reconstruction with double-femurtibia-tunnel method is in consistent with anatomy.It has a better clinical efficacy than the single-femur-tibia-tunnel method.
