Cross Pin Femoral Fixation for Posterior Cruciate Ligament Reconstruction Using Quadruple Hamstring Tendon

ABSTRACT

PURPOSE: The purpose of this study is to introduce new fixation technique for posterior cruciate ligament (PCL) reconstruction using quadruple hamstring tendon autograft. MATERIALS AND METHODS: From September 2001 to March 2002, eight patients received PCL reconstruction using quadruple hamstring autograft for PCL injury without associated procedures for posterolateral complex injures. All femoral tunnels were fixed with cross pins and all tibial tunnels were fixed with Intrafix(Mitek , USA). Clinical assessments consisted of Lysholm knee scores, International Knee Documentation Committee(IKDC) evaluation form and manual maximal side to side difference using KT-2000 arthrometer. RESULTS: The average Lysholm knee score improved from 54 preoperatively to 89 postoperatively. At the final IKDC evaluation, 2 cases were graded as normal, 5 nearly normal, 1 abnormal. Mean side to side difference of manual maximum posterior displacement with knee in 70 degrees flexion using the KT-2000 arthrometer was 3.7mm. CONCLUSION: In PCL reconstruction using quadruple hamstring autograft, cross pins are good fixation method with high strength and stiffness.
