Abstract
Background:
Anterior cruciate ligament (ACL) rupture is one of the most common orthopedic injuries leading to knee instability and functional impairment. While hamstring tendon autografts remain the conventional choice for reconstruction.
Objective:
To compare the functional outcome of ACL reconstruction using peroneus longus tendon graft versus hamstring tendon graft among patients presenting with ACL rupture at a tertiary care hospital.
Methods:
This randomized controlled trial was conducted in the Department of Orthopedics, Jinnah Postgraduate Medical Centre (JPMC), Karachi, over six months following ethical approval from the Institutional Review Board and CPSP. A total of 76 patients aged 20–70 years with ACL rupture and ASA status ≤2 were randomly divided into two equal groups: Group A underwent reconstruction using peroneus longus graft, and Group B using hamstring tendon graft. All procedures were performed arthroscopically under spinal or combined anesthesia. Functional outcomes were assessed at three months postoperatively using the International Knee Documentation Committee (IKDC) and Lysholm Knee Scoring Systems. Data were analyzed using SPSS version 25, and p ≤ 0.05 was considered statistically significant.
Results:
The mean IKDC score was 83.42 ± 6.01 in the peroneus longus group and 78.65 ± 7.10 in the hamstring group (p = 0.002). The mean Lysholm score was 91.08 ± 5.92 and 85.37 ± 7.24, respectively (p < 0.001). Excellent functional outcomes (>90) were observed in 65.8% of Group A and 39.5% of Group B patients (p = 0.01).
Conclusion:
Peroneus longus tendon autograft provided significantly superior short-term functional outcomes compared to hamstring grafts for ACL reconstruction.
