Predictive Value of Preoperative 3-Dimensional Computer Tomography Measurement of Semitendinosus Tendon Harvested for Anterior Cruciate Ligament Reconstruction

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].…”

“…However, there was no significant correlation between the CSA of the ST tendon by 3-D CT and intraoperative measurements [21]. In additional, Hamade et al reported that MRI was not practical for evaluating the tendon size since it requires a long scanning time and high cost [8].…”

Are pre-operative anthropometric parameters helpful in predicting length and thickness of quadrupled hamstring graft for ACL reconstruction in adults? A prospective study and literature review

“…Pre-operative parameters such as age, gender, height, weight, BMI, leg length, thigh circumference, etc., have been reported to be of predictive value in a variety of studies but there is poor consensus [11][12][13][14][15][16][17][18]. Magnetic resonance, 3D tomography, and USG have also been employed to improve the accuracy of pre-operative prediction of hamstring tendon graft harvest data [19][20][21]. Few studies have reported height of the patient to correlate with graft diameter and length and also derived a mathematical equation to predict the adequacy of graft, but reproducibility of this has not been proved [11-13, 16, 18].…”

Clinicoradiological correlation between preoperative measurement of ACL footprint on MRI and intra operative semitendinosis graft diameter

“…In a study that evaluated the length of ST and its CSA with MRI, it was expressed that preoperatively measured ST length was closely related to the intraoperatively measured length of ST, however, contrary to data obtained from MRI studies, an apparent correlation was not found between preoperatively determined CSA and that measured during operation. [9] Erquicia et al compared preoperative USG and MRI measurements of tendon CSA and diameters, and measured during surgery and demonstrated reliability of USG in the preoperative evaluation of CSA which also comparable to MRI results obtained under ×2 magnification. [8] However, in clinical practice, for the diagnostic confirmation of ACL lesions, CT and USG are not routinely used.…”

“…[1,[6][7][8][9][10] In all studies about this subject, both gracilis tendon (GT) and semitendinosus tendon (ST) were used for ACL reconstruction. [1,[6][7][8][9][10] Some authors prefer both ST and GT to obtain 4-stranded autograft, whereas some of them prefer only ST in singlebundle ACL reconstruction. [7,11] This present study was designed for primary ACL reconstruction technique with 4-stranded ST autograft.…”
