Background: Anterior Cruciate Ligament (ACL) injuries are among the most common knee ligament injuries, significantly affecting joint stability and function. While traditional graft options like Bone-Patellar Tendon-Bone (BPTB) and hamstring tendons are widely used in ACL reconstruction, they are associated with donor site morbidity and functional limitations. The Peroneus Longus Tendon (PLT) has emerged as a potential alternative autograft due to its favourable biomechanical properties and minimal donor site morbidity. Aim: To evaluate the functional outcomes and safety of using the autologous peroneus longus tendon as a graft in arthroscopic ACL reconstruction. Methods: This prospective study involved 10 patients with ACL injuries who underwent arthroscopic ACL reconstruction using the peroneus longus tendon autograft at Government Chengalpattu Medical College Hospital from May 2024 to March 2025. Patients were followed up at 1, 3, and 6 months postoperatively. Functional outcomes were assessed using the Lysholm Knee Score, while donor site morbidity was evaluated using the Foot and Ankle Disability Index (FADI). Results: The mean age of the patients was 35.3 ± 10.3 years. The average graft length and diameter were 28.69 ± 0.859 cm and 8.27 ± 0.632 mm, respectively. Postoperative assessments showed significant improvement in knee function, with mean Lysholm and FADI scores of 94.1 ± 3.1 and 97 ± 1.4, respectively (p = 0.001). No significant donor site morbidity or ankle function impairment was observed. Conclusion: The use of the peroneus longus tendon as an autograft in ACL reconstruction demonstrates excellent short-term functional outcomes with minimal donor site morbidity. It presents a viable, safe, and effective alternative graft option for arthroscopic ACL reconstruction
