Resumen:
BACKGROUND AND OBJECTIVE: Currently, there is no stablished pre-operative model that helps the orthopaedic surgeon predict the final graft diameter in anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to determine whether there is a correlation between semitendinosus (ST) and gracilis (GT) cross-sectional area (CSA) evaluated pre-operatively in mm2 using magnetic resonance imaging (MRI) and the final intra-operative ST-GT autograft diameter in mm2.
