Autologous Bone Grafting with Kirschner-wires Fixation for Medial Tibial Defect in Total Knee Arthroplasty-การใช้ Kirschner-wires ยึดตรึงชิ้นกระดูกบริเวณส่วนที่กระดูกขาดหายไปในการผ่าตัดเปลี่ยนข้อเข่าเทียม

Abstract

        Among 331primary total knee arthroplasties in Nakornping Hospital performed from 1 January 2003 to 19 February 2008, six posterior stabilized total knee arthroplasties severely deformed varus knees with large medial tibial bony defects (> 5 mm). The defect was filled with an autologous bone graft obtained from the same knee and fixed with two Kirschner-wires 1.2-1.6 mm in diameter. The patients were reviewed during an average follow up period of 2 years and 2 months (range 6 months to 3 years and 9 months). The graft was completely united in every case without serious complication. Autologous bone grafting with Kirschner-wires fixation is a simple and effective method to deal with the tibial defects in primary total knee arthroplasty.
