Ilahi OA, et al. - Experts ascertained if preoperative magnetic resonance imaging (MRI) could help predict the tendon-only length of the semitendinosus (ST) and the gracilis (G). Data demonstrated a very strong association of MRI estimates of tendon-only length for both the ST and G with operative measurements of these lengths. In cases where MRI scans demonstrated musculotendinous junction (MTJ) of these tendons, the discrepancy between these 2 measurement methods was found to not exceed 3 cm. The surgically measured tendon-only length of the ST was seen to have a strong correlation with its G counterpart.
