Comparing Dimensions of Four-Strand Hamstring Tendon Grafts with Native Anterior and Posterior Cruciate Ligaments

Abstract EN

Background.

The aim of the study was to evaluate whether or not there was any incompatibility between four-strand hamstring tendons taken from the same knee and the dimensions of the ACL and PCL.

Methods.

15 fresh frozen cadaver hamstrings were prepared as four-strand grafts and measurements made of the ACL and PCL circumferences in the midsection were made in the narrowest part of the midsection.

The cross-section areas and diameters were calculated with geometric calculations used to measure the cross-sectional area of cylinders.

Accepting that the geometric insertions were elliptical, the length, width, and area were calculated for entry areas.

Results.

A significant relationship at 96.2% was determined between the ACL mid and the hamstring diameter.

A significant relationship at 96.7% was determined between the ACL and the hamstring mid area.

A significant relationship at 96.4% was determined between the PCL mid and the hamstring diameter.

A significant relationship at 95.7% was determined between the PCL and the hamstring mid area.

Conclusion.

For the reconstruction of ACL and PCL, it was determined that there is less incompatibility between the four-strand hamstring tendons taken from the same knee and the dimensions of the midsection PCL compared to the ACL dimensions.
