Preoperative calculation of the CSA of the hamstring tendons with MRI and US can help to reliably estimate 4ST-GT grafts. In terms of correlation of the CSA with graft diameter, US was comparable to 2× MRI, but 4× MRI showed a much greater accuracy. Threshold values of the CSA of the ST and GT of 25 mm2, 17 mm2, and 14 mm2 with the 2× MRI, 4× MRI, and US methods, respectively, are needed to reliably predict a 4ST-GT graft with a minimum diameter of 8 mm.

A meniscal allograft fixed with the suture-only technique showed a significantly higher degree of extruded meniscal body than that fixed with the bony fixation method, with no influence on the functional outcome. There was also a considerably higher rate of graft tears observed in those menisci fixed only with sutures, although this difference was not statistically significant with the numbers available.
