Reconstruction of cruciate ligaments with peroneus longus tendon: functional and clinical outcome of donor ankle and foot

Introduction: To compare the functional and clinical outcome of donor foot and ankle post peroneus longus tendon harvest in cruciate ligament reconstruction. Materials and methods: Patients with cruciate ligament injury underwent peroneus longus tendon autograft harvest in this prospective trial. After 6 months following peroneus harvest, the Foot and Ankle Disability Index (FADI) was used to evaluate the ankle morbidity at the donor location.

Results: In this study sample of 25 patients, the ankle and foot functions of donor site are grossly preserved in almost all the patients which was evaluated by FADI score pre operatively and post operatively. FADI score of donor site ankle was 99.23 ± 0.77.

Conclusion: The peroneus longus tendon has the benefit of being the easiest autograft to harvest and having the fewest problems, making it the most promising option for cruciate ligament restoration. Due to the lack of postoperative biomechanical morbidity, it might be regarded as the first option.
