摘要: The aim of this study was to evaluate tibial bone tunnel enlargement following four-strand hamstring tendon anterior cruciate ligament (ACL) reconstruction, using a new method magnetic resonance imaging (MRI) assessment. Correlation with clinical outcome also examined. In prospective ACL 24 patients underwent MRI and assessment, at mean follow-up 6.5 months. A semitendinosus gracilis (STG) graft the polyester Soffix (Surgicraft Ltd) fixation device placed via an instrument guided over-the-top femoral route. Cross-sectional area (CSA) perpendicular long axis calculated digitally three levels, MRI. Clinical assessment included physical examination, Lysholm subjective self-evaluation score KT 2000 arthrometric measurement. CSA 33% found. side-to-side KT-2000 difference 1.66 mm 92. We concluded that previously unused evaluation digital direct measurements provides highly accurate found no correlation between enlargement, knee stability, joint function patient satisfaction scores in short term.
