Abstract

Arthroscopic reconstruction of the cruciate ligament of the knee is becoming more and more routine with improved techniques and aids. But the source of grafted tendons is an eternal issue that affects the surgeon’s decision and choice. The two peroneal tendons on the lateral side of the lower leg have the same function as the ankle and pronation of the foot. In particular, the long fibula tendon is used in many orthopedic surgeries to reconstruct the external ligaments of the knee such as the external ligament of the ankle, reconstruct the heel tendon. Twenty cadaveric fibularis longus tendons were taken from the Anatomy Department of Ho Chi Minh City Medicine and Pharmacy University. Fibularis longus tendon length 29.25 ± 2.1cm; the distances from fibularis longus tendon to deep fibular nerve and superficial fibular nerve 71.1 ± 8.63mm, no sp (longitudinal tear) of fibularis longus tendon, the maximum tensile strength and of fibularis longus tendon 1170.4 ± 203N, the maximum length of the fibularis longus tendon rupture 14.29 ± 3.88mm. There was no split of fibularis longus tendon. No sign of impact on adjacent anatomy structures was found. The maximum tensile strength of the fibularis longus tendon was equivalent to other grafts, such as the Hamstrings and patellar tendons.
