Tensile strength comparison between hamstring tendon, patellar tendon, quadriceps tendon and peroneus longus tendon: A cadaver research

Abstract Knee ligament injury is a frequent occurrence. Ligament reconstruction using tendon graft is the best therapy recommendation in the case of severe knee ligament injury. Tendon graft that is oftenly used are hamstring tendon, patellar tendon (BPTB), quadriceps tendon and peroneus longus tendon have been proposed as tendon graft donor. Biomechanically, tensile strength from tendon graft is the main factor that greatly contributes to the success of ligament reconstruction procedure. Numerous researches have been done to calculate tensile strengths of hamstring and patellar tendon, but there has not been a research done yet on the comparison of the tensile strengths of peroneus longus tendon, hamstring, patellar tendon and quadriceps tendon. This research will strive to record the tensile strengths of peroneus longus tendon, hamstring, patellar tendon and quadriceps tendon as well as their comparison. Population of this research is 6 cadavers that have met the exclusion and inclusion criterias. From population above, 48 samples are retrieved and further divided into 4 groups. 12 samples for quadriceps tendon group, 12 samples for hamstring group, 12 samples for peroneus longus tendon group and 12 samples for patellar tendon group. Tensile strength measurement will then be done on each tendon by clamping both ends of examined tendon, then pulled on one side until tendon ruptures. Results are then read with a tensile tester. Tensile strength of peroneus longus tendon is not significantly different in comparison to hamstring tendon (p > 0,05). Whereas when compared to patellar and quadriceps tendons, peroneus longus and hamstring tendons have tensile strengths that are significantly higher (p
