Cross-sectional area measurement of the semitendinosus tendon for anterior cruciate ligament reconstruction

Pre-operative ultrasonographic prediction of hamstring autograft size for anterior cruciate ligament reconstruction surgery

“…The use of the cross section area of the hamstring tendon from magnetic resonance imaging (MRI) to predict the final hamstring autograft size for anterior cruciate ligament reconstruction has been described previously, and has proven to be a reliable method [14][15][16][17]. However, MRI is an expensive procedure and takes time to carry out.…”

Hamstring Autograft Size Can Be Predicted and Is a Potential Risk Factor for Anterior Cruciate Ligament Reconstruction Failure

“…This was performed at similar locations along the knee joint and was obtained by software analysis with a region-of-interest tool based on the initial protocol developed by Bickel et al 23 Other than the earliest attempt to predict graft diameter by Yasumoto et al 25 in 1997, the only study based on CT, all 5 subsequent studies found significant Pearson correlation coefficients between CSA and intraoperative graft diameter. [23][24][25][26][27][28] The sample size of most of the imaging studies was under half that of the average anthropometric study (42 patients v 124 patients). The study by Erquicia et al 28 investigated both ultrasound-and MRI-based prediction and found that both can correlate significantly with intraoperative graft diameter.…”

Hamstring graft sizes differ between Chinese and Caucasians

“…Hamstring graft diameter prediction For prediction of the graft diameter, some investigators have used pre-operative magnetic resonance imaging (MRI) or 3-D CT to measure the cross sectional area (CSA) [2,8,21]. However, there was no significant correlation between the CSA of the ST tendon by 3-D CT and intraoperative measurements [21].…”
