The research objective was to compare the clinical and radiological results of single-bundle versus double-bundle arthroscopic anterior cruciate ligament (ACL) replacement.
Method: 80 patients with isolated ACL injuries had surgery between July 2020 and July 2021, with groups for single bundle (SB) and double bundle (DB) reconstructions each consisting of 40 individuals. The GNRB arthrometer, the International Knee Documentation Committee, and the Lysholm scale were used to evaluate the results. The lateral pivot-shift test was used to evaluate rotational stability. To compare the repaired ACL graft orientation, postoperative magnetic resonance imaging (MRI) was done.
Result: The average follow-up was 18.2 months for the DB group and 14.8 months for the SB group. The mean Lysholm score was 94.12±2.66 in the SB group and 93.12±3.30 in the DB group at the time of the final follow-up (P value = 0.201, statistically insignificant). According to the objective IKDC scores, all of the patients in both groups were in grade A or B. The mean differential anterior tibial translation in the SB group was 1.44 ± 0.5 mm and in the DB group it was 1.16 ± 0.7 mm (P = 0.104, NS). In the DB group, all of the pivot shift tests were negative, whereas in the SB group, three patients showed positive results. According to an MRI of surgically repaired knees, both groups' mean sagittal and mean coronal ACL graft-tibial angles were equivalent (P value > 0.04, NS).
Conclusion: At an average of 15 months of follow-up, there was no statistically significant difference between the single-bundle and double-bundle ACL repair groups in terms of knee stability, knee ratings, subjective assessments, or MRI examination of graft inclination angles.
