Comparing the Stiffness of Peroneus Longus Tendon Versus Hamstrings in Anterior Cruciate Ligament Reconstruction: A Biomechanical Study
The use of autografts originating from either hamstring tendons or peroneus longus tendons is a surgical option in anterior cruciate ligament (ACL) reconstruction.
This research aimed to compare the tensile strength between the hamstring tendon and the peroneus longus tendon in ACL reconstruction. The hypothesis of this study was: Peroneus longus grafts have tensile strength equal to hamstring grafts based on living donor patients.
This cross-sectional study was a biomechanical study examining means and standard deviations (SD) by comparing the tensile strength of peroneus longus tendons and hamstring tendons when used as autograft donors in ACL reconstruction.
In this study, 51 patients with reconstructive ACL were enrolled. The mean diameter of the hamstring tendon was 7.86 with SD ± 0.69, while the mean diameter of peroneus longus tendon was 7.67 with SD ± 0.63. The mean diameter of the peroneus longus graft was not significantly different. The mean displacement on the hamstring tendon was 2.44 with SD ± 0.42, while the peroneus longus tendon was 2.06 with SD ± 0.14. The peroneus longus tendon had significantly more tensile strength compared to the hamstring tendon.
Diameter of the peroneus longus graft was not significantly different from the hamstring graft. However, the peroneus longus graft had more tensile strength than the hamstring graft based on living donor patients.
