Background: Peroneus longus tendon autograft resembles hamstring tendon's biomechanical strength. Thus, peroneus longus is a potential graft in reconstructive orthopaedic procedures. However, there was few study in evaluation of peroneus longus usage in ACL reconstruction. This study aimed to quantify the clinical outcome and donor site morbidity in ACL reconstruction using peroneus longus tendon autograft. Methods: Patients who suffered isolated ACL injury were enrolled and underwent isolated single bundle ACL reconstruction using peroneus longus autograft. Functional score (IKDC, Modified Cincinnati, and Tegner-Lysholm score) were assessed at pre-operative and 2-years after surgery. Graft diameter was measured intraoperative. Donor site morbidities were assessed with thigh circumference measurement and ankle scoring using AOFAS and FADI. We also measured serial hop test. Results: Seventy-five patients fulfilled inclusion criteria. Peroneus longus graft diameter was 8.38 ± 0.68 mm. There was significant difference between pre and 2-years post-operative functional score in IKDC, Modified Cincinnati, and Tegner-Lysholm score. Mean of AOFAS was 98.93 ± 3.10 and FADI was 99.79 ± 0.59 with no significant decrease of thigh circumference, and good serial hop test result. Conclusion: ACL reconstruction with peroneus longus autograft has excellent functional score in IKDC, Modified Cincinnati, Tegner-Lysholm score at 2-years follow up with the advantages of greater graft diameter, less thigh hypotrophy, good serial hop test result, and excellent ankle function based on AOFAS and FADI score.

Introduction Soft tissue injuries, particularly ligaments and tendons, are the most common injuries in sports, account for more than 50% of all injuries and often require orthopedic surgery. According to data in the general population, the incidence rate of anterior cruciate ligament (ACL) injury was 1:3500. The treatment option of ACL injury cases include physical exercise and reconstruction surgery. Graft options for the ACL reconstruction include:autograft and allograft. One of the most popular autograft is hamstring. The use of hamstrings in ACL reconstruction still arguing among the expert. The choice of autograft that can be chosen as a new alternative is the peroneus longus tendon. Currently, there is very few biomechanical study on peroneus longus strength as an alternative choice of autograft in ACL reconstruction. The study to determine the tensile strength of the peroneus longus tendon was conducted by the researcher as a preliminary study that could bring new perspective for future studies. Materials and methods This is an experimental research. Six human cadaveric specimens as research material. Each cadaver was treated by taking hamstring and peroneus from both lower limbs. The hamstring and peroneal tendons were then measured by applying the Hydraulic Servo Pulser tensile test apparatus. Data on tensile strength comparison between peroneal tendon and hamstring were analyzed by descriptive and inferential statistics. Result From the measurement results, it is known that hamstring has lower average tensile strength value compared to peroneus without significant difference (p > 0.05). Conclusion The tensile strength of the peroneus longus tendon, which is similar to that of hamstring, gives information that both have the same biomechanic properties. Peroneus longus should not be used as a first option in ACL reconstruction, but may be used as an alternative donor in cases involving multiple instability that require more tendon donors in the reconstruction.
