Anterior Cruciate Ligament Tibial Footprint Size as Measured on Magnetic Resonance Imaging: Does It Reliably Predict Actual Size?

“…Finally, the third study reported good agreement between MRI and intraoperative measurement of the area of the ACL tibial insertion site. 5 These findings confirm that the size of the ACL tibial footprint on MRI could be a useful parameter for predicting its actual size.…”

“…Several previous studies showed that the shape of the ACL tibial footprint differs among patients (elliptical, triangular, C-shape, etc). 5,6,26,27 Therefore, the size of the ACL tibial footprint also differs. 15,16,23,24,26 Predictive equations for actual size that were developed on the basis of MRI measurement and sex showed good concordance correlation coefficients.…”

Correlação entre características antropométricas individuais e as medidas da fóvea tibial do ligamento cruzado anterior

“…The comparison between our results and those of other authors, by the various modes of evaluation, is found in ►Table 3. [3][4][5][6][7][8][9][10][11][12][13][18][19][20][21][22][23][24] In fact, Lord et al 25 published a study of the function of the ACL tibial insertion fibers in the resistance of anterior and rotational displacements, with robotics, in six degrees of freedom of movement. They concluded that the central, posterior and lateral fibers of the ACL tibial insertion play a secondary role in the restriction of tibial displacements and that the most important fibers are the anterior and the anteromedial peripheral portion.…”

“…4 Therefore, anticipating the dimensions of the ACL insertion can be valuable for better surgical planning. This can be done by CT scan 5,6 or magnetic resonance imaging (MRI), [7][8][9][10][11] but it can also be predicted by the individual physical characteristics. 3,4 In this decade, some authors sought to correlate the weight and height of patients with the size of their tibial ACL insertion.…”

Regression modelling combining MRI measurements and patient anthropometry for patient screening and prediction of graft diameter in hamstring autograft arthroscopic ACL reconstruction

“…Recently published papers have noted individual variations in patients' native ACL anatomy, such as in terms of the tibial insertion site, which may influence graft size. 25 , 26 Therefore patient-specific ACL reconstruction using individualised graft characteristics to reproduce native patient anatomy may pave the way to better functional and structural outcomes.…”
