How to Improve the Prediction of Quadruple Semitendinosus and Gracilis Autograft Sizes with Magnetic Resonance Imaging and Ultrasonography

摘要

Objectives:To determine if preoperative ultrasonographic measurement of the cross-sectional area (CSA) of the gracilis tendon (GT) and semitendinosus tendon (ST) could predict the diameter of the quadrupled ST-GT autograft as accurately as the magnetic resonance imaging (MRI), and how different magnifications of the MRI slices could influence the accuracy of the measurement.
