EARLY RESULTS OF A RANDOMIZED CONTROLLED TRIAL COMPARING HAMSTRING AND PERONEUS LONGUS TENDON AUTOGRAFTS FOR ARTHROSCOPIC ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION

The British Association for Surgery of the Knee (BASK) May 2022 Meeting, Newport, Wales, 17–18 May 2022.



Abstract

Abstract

Purpose

This study aims to compare the clinical and functional outcomes and donor site morbidity of anterior cruciate ligament reconstruction with hamstring tendon autograft and peroneus longus tendon autograft in patients with complete anterior cruciate ligament rupture.

Methods

Patients who underwent ACL reconstruction from February 2018 to July 2019 were randomly allocated into two groups (hamstring and peroneus longus). Functional scores (IKDC and Lysholm scores) and pain intensity by visual analogue score were recorded preoperatively, 3, 6months, 1, and 2 years postoperatively. Donor site morbidities were assessed with thigh circumference measurements in hamstring group and ankle scoring with the American foot and ankle score in peroneus longus group.

Results

Sixty patients (hamstring n = 30, peroneus n = 30) met the inclusion criteria. The functional scores (IKDC and Lysholm) did not show statistical difference among the two groups at two years follow-up (P- value>0.05). The means values for visual analogue score after two years in the hamstring and Peroneus longus group was 1±0.74 and 1.03± 1.06, respectively. In peroneus longus group, the mean foot and ankle score was 98.63±3.88 (range= 85–100). A significant difference was found in the hamstring group between operated and non-operated thigh circumferences with p- value <0.001.

Conclusions

Peroneus longus tendon autograft is an easily accessible tendon for ACL reconstruction and gives comparable functional outcomes as hamstring tendon with no additional donor site morbidity in our study.
