BACKGROUND Anterior cruciate ligament (ACL) reconstruction commonly uses a hamstring tendon autograft, but the peroneus longus tendon can also be used. This study aimed to compare outcomes of anterior cruciate ligament reconstruction in 106 patients using peroneus longus tendon and hamstring tendon autografts. MATERIAL AND METHODS ACL repair was performed on 54 patients using a hamstring tendon autograft and 52 patients with a peroneus longus tendon autograft. Knee function was assessed using the International Knee Documentation Committee (IKDC) and Lysholm scores, while the ankle was evaluated using the American Orthopedic Foot and Ankle Score (AOFAS) and the Foot & Ankle Disability Index (FADI) scores. Donor-site morbidity and graft characteristics were compared. RESULTS There was no difference between the 2 groups in terms of knee IKDC and Lysholm scores (p=0.49, p=0.68, respectively). The diameter of the peroneus longus tendon graft (8.56±0.93) was significantly larger than the hamstring tendon (7.44±0.6) (p<0.001). The peroneus graft harvesting time was significantly shorter (p<0.001). Thigh hypotrophy and donor-site morbidity were significantly higher in the hamstring group (p<0.001 and p=0.006). The donor ankle AOFAS score was 93.46±3.8, and the FADI score was 93.48±4.6. No morbidity associated with the peroneus longus graft was observed. CONCLUSIONS Patients who underwent ACL reconstruction using the peroneus longus tendon experienced faster knee rehabilitation and less donor-site morbidity, such as thigh hypotrophy and knee pain. The peroneus longus tendon, with its larger diameter, fewer graft-related complications, and similar knee scores compared to the hamstring group, is considered a suitable alternative graft source.
