A comparison of functional knee outcomes post-arthroscopic anterior cruciate ligament (ACL) reconstruction using hamstring and peroneus longus (PL) autograft

Abstract

Background: Hamstring autograft (HA) is the most common graft used in ACL reconstruction procedures. However, harvesting HA could weaken the secondary stabilizer of the knee joint. Peroneus longus grafts (PL) is a novel option secondary to hamstring graft with less morbidity at the knee joint. We intended to determine whether peroneus longus autograft (PL) is a comparable alternative to hamstring autograft for ACL Reconstruction. Methods: 84 patients were grouped into "hamstring" (n = 51) and "peroneus longus" (n = 33) groups, with a mean age of 26.2 ± 5.9 in the Hamstring group and a mean age of 26.4 ± 6.6 in peroneus group. We obtain secondary data from the medical records of several hospitals in Makassar. Results: There was a significant difference in Lysholm score (p<0.05) in the hamstring group with peroneus at 6 months and 12 months postoperatively for IKDC score, anterior translation, Power Grading Flexi-Extension, ROM on flexion, and extension. In addition, in muscle atrophy, the Hamstring group compared to the peroneus group also showed a significant difference (p=0.001). Conclusion: The study's results did not show significant differences between the hamstring and peroneus groups other than atrophy of thigh muscles in the hamstring group. Based on the results of this study, we conclude peroneus longus graft is one of the graft options in ACL reconstruction surgery.
