Abstract: Background: Hamstring and peroneus longus tendon auto graft has similar biomechanical strength. Peroneus longus is a potential graft in reconstructive orthopaedic procedures. There was few study in evaluation of peroneus longus usage in ACL reconstruction. We aimed to quantify the outcome and donor site morbidity in ACL reconstruction using peroneus longus tendon auto graft.
Methods: Patients who suffered isolated ACL injury were enrolled in the study and underwent trans-portal single bundle ACL reconstruction using peroneus longus auto graft. Functional score (IKDC, Modified Cincinnati, and Tegner-Lysholm score) were assessed at pre-operative and 2-years after surgery. Graft diameter was measured at the time of graft harvest. Thigh circumference, ankle score (AOFAS and FADI) and serial hop test were assessed to evaluate donor site morbidities.
Results: Sixty-eight patients fulfilled inclusion criteria. Peroneus longus graft diameter was 8.16±0.65 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 93.98±2.95 and FADI was 94.80±0.56 with no significant decrease of thigh circumference, and good serial hop test result.
Conclusion: ACL reconstruction with peroneus longus auto graft has excellent functional score in IKDC, Modified Cincinnati, Tegner-Lysholm score at 2-years follow up with the advantages of larger graft diameter, less thigh hypotrophy, good serial hop test result, and excellent ankle function based on AOFAS and FADI score.
